phpdbg aims to be a lightweight, powerful, easy to use debugging platform for PHP5.4+

• Flexible Breakpoints (Class Method, Function, File:Line, Address)
• Easy Access to PHP with built-in eval()
• Easy Access to Currently Executing Code
• Userland API
• SAPI Agnostic - Easily Integrated
• PHP Configuration File Support
• JIT Super Globals - Set Your Own !!
• Optional readline Support - Comfortable Terminal Operation
• Easy Operation - See Help :)

Planned

• Improve Everything :)

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
./config.nice
make -j8
make install-phpdbg

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

Command Line Options

The following switchess 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()

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