phpdbg - The interactive PHP debugger phpdbg [OPTION] [-eFILE] phpdbg a lightweight, powerful, easy to use debugging platform for PHP5. The following switches are implemented (just like cli SAPI):

-n No php.ini file will be used

-c path|file Look for php.ini file in the directory path or use the specified file

-z file Load Zend extension file

-d foo[=bar] Define INI entry foo with value bar

The following switches change the default behaviour of phpdbg:

-v Disables quietness

-s Enabled stepping

-e file Sets execution context

-b Disables use of colour on the console

-I Ignore .phpdbginit (default init file)

-i path|\ffile Override .phpgdbinit location (implies -I)

-O file Set oplog output to file

-q Do not print banner on startup

-r Jump straight to run

-E Enable step through eval()

Passing -rr will cause phpdbg to quit after execution, rather than returning to the console Written by Felipe Pena, Joe Watkins and Bob Weinand, formatted by Ondřej Surý for Debian project.
