Documentation for class Archive_Tar
===================================
Last update : 2001-08-15
Overview :
----------
The Archive_Tar class helps in creating and managing GNU TAR format
files compressed by GNU ZIP or not.
The class offers basic functions like creating an archive, adding
files in the archive, extracting files from the archive and listing
the archive content.
It also provide advanced functions that allow the adding and
extraction of files with path manipulation.
Sample :
--------
// ----- Creating the object (uncompressed archive)
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->setErrorHandling(PEAR_ERROR_PRINT);
// ----- Creating the archive
$v_list[0]="file.txt";
$v_list[1]="data/";
$v_list[2]="file.log";
$tar_object->create($v_list);
// ----- Adding files
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/";
$v_list[2]="log/file.log";
$tar_object->add($v_list);
// ----- Adding more files
$tar_object->add("release/newfile.log release/readme.txt");
// ----- Listing the content
if (($v_list = $tar_object->listContent()) != 0)
for ($i=0; $i<sizeof($v_list); $i++)
{
echo "Filename :'".$v_list[$i][filename]."'<br>";
echo " .size :'".$v_list[$i][size]."'<br>";
echo " .mtime :'".$v_list[$i][mtime]."' (".date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")<br>";
echo " .mode :'".$v_list[$i][mode]."'<br>";
echo " .uid :'".$v_list[$i][uid]."'<br>";
echo " .gid :'".$v_list[$i][gid]."'<br>";
echo " .typeflag :'".$v_list[$i][typeflag]."'<br>";
}
// ----- Extracting the archive in directory "install"
$tar_object->extract("install");
Public arguments :

None
Public Methods :
----------------
Method : Archive_Tar($p_tarname, $compress = false)
Description :
Archive_Tar Class constructor. This flavour of the constructor only
declare a new Archive_Tar object, identifying it by the name of the
tar file.
If the compress argument is set the tar will be read or created as a
gzip compressed TAR file.
Arguments :
$p_tarname : A valid filename for the tar archive file.
$p_compress : true/false. Indicate if the archive need to be
compressed or not.
Return value :
The Archive_Tar object.
Sample :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object_compressed = new Archive_Tar("tarname.tgz", true);
How it works :
Initialize the object.
Method : create($p_filelist)
Description :
This method creates the archive file and add the files / directories
that are listed in $p_filelist.
If the file already exists and is writable, it is replaced by the
new tar. It is a create and not an add. If the file exists and is
read-only or is a directory it is not replaced. The method return
false and a PEAR error text.
The $p_filelist parameter can be an array of string, each string
representing a filename or a directory name with their path if
needed. It can also be a single string with names separated by a
single blank.
See also createModify() method for more details.
Arguments :
$p_filelist : An array of filenames and directory names, or a single
string with names separated by a single blank space.
Return value :
true on success, false on error.
Sample 1 :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling
$v_list[0]="file.txt";
$v_list[1]="data/"; (Optional '/' at the end)
$v_list[2]="file.log";
$tar_object->create($v_list);
Sample 2 :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling
$tar_object->create("file.txt data/ file.log");
How it works :
Just calling the createModify() method with the right parameters.
Method : createModify($p_filelist, $p_add_dir, $p_remove_dir = "")
Description :
This method creates the archive file and add the files / directories
that are listed in $p_filelist.
If the file already exists and is writable, it is replaced by the
new tar. It is a create and not an add. If the file exists and is
read-only or is a directory it is not replaced. The method return
false and a PEAR error text.
The $p_filelist parameter can be an array of string, each string
representing a filename or a directory name with their path if
needed. It can also be a single string with names separated by a
single blank.
The path indicated in $p_remove_dir will be removed from the
memorized path of each file / directory listed when this path
exists. By default nothing is removed (empty path "")
The path indicated in $p_add_dir will be added at the beginning of
the memorized path of each file / directory listed. However it can
be set to empty "". The adding of a path is done after the removing
of path.
The path add/remove ability enables the user to prepare an archive
for extraction in a different path than the origin files are.
See also addModify() method for file adding properties.
Arguments :
$p_filelist : An array of filenames and directory names, or a single
string with names separated by a single blank space.
$p_add_dir : A string which contains a path to be added to the
memorized path of each element in the list.
$p_remove_dir : A string which contains a path to be removed from
the memorized path of each element in the list, when
relevant.
Return value :
true on success, false on error.
Sample 1 :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling
$v_list[0]="file.txt";
$v_list[1]="data/"; (Optional '/' at the end)
$v_list[2]="file.log";
$tar_object->createModify($v_list, "install");
// files are stored in the archive as :
// install/file.txt
// install/data
// install/data/file1.txt
// install/data/... all the files and sub-dirs of data/
// install/file.log
Sample 2 :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/"; (Optional '/' at the end)
$v_list[2]="log/file.log";
$tar_object->createModify($v_list, "install", "dev");
// files are stored in the archive as :
// install/file.txt
// install/data
// install/data/file1.txt
// install/data/... all the files and sub-dirs of data/
// install/log/file.log
How it works :
Open the file in write mode (erasing the existing one if one),
call the _addList() method for adding the files in an empty archive,
add the tar footer (512 bytes block), close the tar file.
Method : addModify($p_filelist, $p_add_dir, $p_remove_dir="")
Description :
This method add the files / directories listed in $p_filelist at the
end of the existing archive. If the archive does not yet exists it
is created.
The $p_filelist parameter can be an array of string, each string
representing a filename or a directory name with their path if
needed. It can also be a single string with names separated by a
single blank.
The path indicated in $p_remove_dir will be removed from the
memorized path of each file / directory listed when this path
exists. By default nothing is removed (empty path "")
The path indicated in $p_add_dir will be added at the beginning of
the memorized path of each file / directory listed. However it can
be set to empty "". The adding of a path is done after the removing
of path.
The path add/remove ability enables the user to prepare an archive
for extraction in a different path than the origin files are.
If a file/dir is already in the archive it will only be added at the
end of the archive. There is no update of the existing archived
file/dir. However while extracting the archive, the last file will
replace the first one. This results in a none optimization of the
archive size.
If a file/dir does not exist the file/dir is ignored. However an
error text is send to PEAR error.
If a file/dir is not readable the file/dir is ignored. However an
error text is send to PEAR error.
If the resulting filename/dirname (after the add/remove option or
not) string is greater than 99 char, the file/dir is
ignored. However an error text is send to PEAR error.
Arguments :
$p_filelist : An array of filenames and directory names, or a single
string with names separated by a single blank space.
$p_add_dir : A string which contains a path to be added to the
memorized path of each element in the list.
$p_remove_dir : A string which contains a path to be removed from
the memorized path of each element in the list, when
relevant.
Return value :
true on success, false on error.
Sample 1 :
$tar_object = new Archive_Tar("tarname.tar");
[...]
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/"; (Optional '/' at the end)
$v_list[2]="log/file.log";
$tar_object->addModify($v_list, "install");
// files are stored in the archive as :
// install/file.txt
// install/data
// install/data/file1.txt
// install/data/... all the files and sub-dirs of data/
// install/file.log
Sample 2 :
$tar_object = new Archive_Tar("tarname.tar");
[...]
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/"; (Optional '/' at the end)
$v_list[2]="log/file.log";
$tar_object->addModify($v_list, "install", "dev");
// files are stored in the archive as :
// install/file.txt
// install/data
// install/data/file1.txt
// install/data/... all the files and sub-dirs of data/
// install/log/file.log
How it works :
If the archive does not exists it create it and add the files.
If the archive does exists and is not compressed, it open it, jump
before the last empty 512 bytes block (tar footer) and add the files
at this point.
If the archive does exists and is compressed, a temporary copy file
is created. This temporary file is then 'gzip' read block by block
until the last empty block. The new files are then added in the
compressed file.
The adding of files is done by going through the file/dir list,
adding files per files, in a recursive way through the
directory. Each time a path need to be added/removed it is done
before writing the file header in the archive.
Method : add($p_filelist)
Description :
This method add the files / directories listed in $p_filelist at the
end of the existing archive. If the archive does not yet exists it
is created.
The $p_filelist parameter can be an array of string, each string
representing a filename or a directory name with their path if
needed. It can also be a single string with names separated by a
single blank.
See addModify() method for details and limitations.
Arguments :
$p_filelist : An array of filenames and directory names, or a single
string with names separated by a single blank space.
Return value :
true on success, false on error.
Sample 1 :
$tar_object = new Archive_Tar("tarname.tar");
[...]
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/"; (Optional '/' at the end)
$v_list[2]="log/file.log";
$tar_object->add($v_list);
Sample 2 :
$tar_object = new Archive_Tar("tarname.tgz", true);
[...]
$v_list[0]="dev/file.txt";
$v_list[1]="dev/data/"; (Optional '/' at the end)
$v_list[2]="log/file.log";
$tar_object->add($v_list);
How it works :
Simply call the addModify() method with the right parameters.
Method : extract($p_path = "")
Description :
This method extract all the content of the archive in the directory
indicated by $p_path.If $p_path is optional, if not set the archive
is extracted in the current directory.
While extracting a file, if the directory path does not exists it is
created.
See extractModify() for details and limitations.
Arguments :
$p_path : Optional path where the files/dir need to by extracted.
Return value :
true on success, false on error.
Sample :
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->extract();
How it works :
Simply call the extractModify() method with appropriate parameters.
Method : extractModify($p_path, $p_remove_path)
Description :
This method extract all the content of the archive in the directory
indicated by $p_path. When relevant the memorized path of the
files/dir can be modified by removing the $p_remove_path path at the
beginning of the file/dir path.
While extracting a file, if the directory path does not exists it is
created.
While extracting a file, if the file already exists it is replaced
without looking for last modification date.
While extracting a file, if the file already exists and is write
protected, the extraction is aborted.
While extracting a file, if a directory with the same name already
exists, the extraction is aborted.
While extracting a directory, if a file with the same name already
exists, the extraction is aborted.
While extracting a file/directory if the destination directory exist
and is write protected, or does not exist but can not be created,
the extraction is aborted.
If after extraction an extracted file does not show the correct
stored file size, the extraction is aborted.
When the extraction is aborted, a PEAR error text is set and false
is returned. However the result can be a partial extraction that may
need to be manually cleaned.
Arguments :
$p_path : The path of the directory where the files/dir need to by
extracted.
$p_remove_path : Part of the memorized path that can be removed if
present at the beginning of the file/dir path.
Return value :
true on success, false on error.
Sample :
// Imagine tarname.tar with files :
// dev/data/file.txt
// dev/data/log.txt
// readme.txt
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->extractModify("install", "dev");
// Files will be extracted there :
// install/data/file.txt
// install/data/log.txt
// install/readme.txt
How it works :
Open the archive and call a more generic function that can extract
only a part of the archive or all the archive.
See extractList() method for more details.
Method : listContent()
Description :
This method returns an array of arrays that describe each
file/directory present in the archive.
The array is not sorted, so it show the position of the file in the
archive.
The file informations are :
$file[filename] : Name and path of the file/dir.
$file[mode] : File permissions (result of fileperms())
$file[uid] : user id
$file[gid] : group id
$file[size] : filesize
$file[mtime] : Last modification time (result of filemtime())
$file[typeflag] : "" for file, "5" for directory
Arguments :
Return value :
An array of arrays or 0 on error.
Sample :
$tar_object = new Archive_Tar("tarname.tar");
if (($v_list = $tar_object->listContent()) != 0)
for ($i=0; $i<sizeof($v_list); $i++)
{
echo "Filename :'".$v_list[$i][filename]."'<br>";
echo " .size :'".$v_list[$i][size]."'<br>";
echo " .mtime :'".$v_list[$i][mtime]."' (".
date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")<br>";
echo " .mode :'".$v_list[$i][mode]."'<br>";
echo " .uid :'".$v_list[$i][uid]."'<br>";
echo " .gid :'".$v_list[$i][gid]."'<br>";
echo " .typeflag :'".$v_list[$i][typeflag]."'<br>";
}
How it works :
Call the same function as an extract however with a flag to only go
through the archive without extracting the files.
Method : extractList($p_filelist, $p_path = "", $p_remove_path = "")
Description :
This method extract from the archive only the files indicated in the
$p_filelist. These files are extracted in the current directory or
in the directory indicated by the optional $p_path parameter.
If indicated the $p_remove_path can be used in the same way as it is
used in extractModify() method.
Arguments :
$p_filelist : An array of filenames and directory names, or a single
string with names separated by a single blank space.
$p_path : The path of the directory where the files/dir need to by
extracted.
$p_remove_path : Part of the memorized path that can be removed if
present at the beginning of the file/dir path.
Return value :
true on success, false on error.
Sample :
// Imagine tarname.tar with files :
// dev/data/file.txt
// dev/data/log.txt
// readme.txt
$tar_object = new Archive_Tar("tarname.tar");
$tar_object->extractList("dev/data/file.txt readme.txt", "install",
"dev");
// Files will be extracted there :
// install/data/file.txt
// install/readme.txt
How it works :
Go through the archive and extract only the files present in the
list.
