phpdbg aims to be a lightweight, powerful, easy to use debugging platform for PHP 5.4+

Installation
============

To install **phpdbg**, you must compile the source against your PHP installation sources, and enable the SAPI with the configure command.

```
cd /usr/src/php-src/sapi
git clone https://github.com/krakjoe/phpdbg
cd ../
./buildconf --force
./configure --enable-phpdbg
make -j8
make install-phpdbg
```

Where the source directory has been used previously to build PHP, there exists a file named *config.nice* which can be used to invoke configure with the same
parameters as were used by the last execution of *configure*.

**Note:** PHP must be configured with the switch --with-readline for phpdbg to support history, autocompletion, tab-listing etc.

Command Line Options
====================

The following switches are implemented (just like cli SAPI):

 - -n ignore php ini
 - -c search for php ini in path
 - -z load zend extension
 - -d define php ini entry

The following switches change the default behaviour of phpdbg:

 - -v disables quietness
 - -s enabled stepping
 - -e sets execution context
 - -b boring - disables use of colour on the console
 - -I ignore .phpdbginit (default init file)
 - -i override .phpgdbinit location (implies -I)
 - -O set oplog output file
 - -q do not print banner on startup
 - -r jump straight to run
 - -E enable step through eval()
 - -l listen ports for remote mode
 - -a listen address for remote mode
 - -S override SAPI name

**Note:** Passing -rr will cause phpdbg to quit after execution, rather than returning to the console.
