Xdebug Configuration

Xdebug Installation

 

Address: http://xiaobin.net/201007/using-vim-and-xdebug-to-debug-php-code/

In principle, this debugging method relies mainly on the vim plug-in "Remote PHP Debugger", which implements a dbgp server. During debugging, xdebug establishes a connection with the server, receives Debugging commands from the server, and returns the debugging result.

Installation and configuration

Xdebug

Installation:

Ubuntu directApt-Get install php5-xdebugInstall

To/Usr/lib/PhP5/20090626 + LFS You Can See That xdebug. So can be copied to your specified module address.

 

Configuration :(PHP. iniFile)

• Load xdebug extension:
  

  Zend_extension =/<Extension_dir>/Xdebug. So# <Extension_dir> the directory you copied

• Configure xdebug to enable dbgp remote debugging
  

  Xdebug. remote_enable = on
  Xdebug. remote_handler = dbgp

Vim debugger plug-in

This is simple. You only need to download the plug-in and decompress it ~ /. Vim/plugin directory

Debugging process

Use Vim to open the PHP file to be debugged and press<F5>Enter the debugging status. Please go to the PHP debugging guide, which describes in detail.

Notes

In the actual process, if you find that PHP debugging is still not working properly after the installation is complete, it may be caused by the following reasons:

I,Xdebug loading failed

You can use phpinfo or "PHP-M" to check whether xdebug is successfully loaded. The reason for loading failure may be that PHP is "Debug build" (which can be confirmed through phpinfo). Therefore, "zend_extension =/" should not be used in PHP. ini/<Extension_dir>/Xdebug. So, instead of zend_extension_ Debug=/<Extension_dir>/Xdebug. So ";

In other aspects, check whether the xdebug. So path is correct, and whether the apache service or FastCGI service is restarted.

Phpinfo is displayed as follows, indicating normal

II. The debugging session has expired.

Xdebug uses a cookie to determine whether you are debugging the conversation. Note that the cookie expires for one hour. One day when you work hard, you find that VIM + xdebug is still working. Why don't you do it again? Most of the reason is that this session has expired.

As long as the parameter"Xdebug_session_start = 1", The debugging session will last for 1 hour.

Access path:

For Clean URLs use:Http://example.com/admin/feature? Xdebug_session_start = 1

Otherwise use:Http://example.com? Q = admin/feature & xdebug_session_start = 1

 

4. Change the debugging wait time (5 seconds by default)

 

Edit debuger. py

 

 

 2. Press <F5> and browse PHP file within 5 seconds .:-)
If you did setup correctly, server will make connection to vim.
[You can change port by editing last line of Debugger. Vim]

All the windows currently opened will be closed and debugger interface will be shown.
