Vim xdebug Debugging php PHP remote Debugging

Xdebug Configuration

Xdebug Installation

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

In principle, this kind of debugging method mainly relies on vim plug-in "remote PHP Debugger" to implement, the plug-in implements a DBGP server. When debugging, Xdebug will establish a connection with the server to communicate, receive debug commands from the server and return the debug results.

Installation and Configuration

Xdebug

Installation:

Ubuntu under direct apt-get install Php5-xdebug installation

To/usr/lib/php5/20090626+lfs can see xdebug.so can be copied to the address of the module you specify

Configuration: (php.ini file)

Load Xdebug Extension:

zend_extension=/ /xdebug.so # Copy to the directory for you

Configure Xdebug to turn on DBGP remote debugging

Xdebug.remote_enable=on
Xdebug.remote_handler=dbgp

Vim's Debugger Plugin

This simple, just need to download the plugin back, unzip and put into the ~/.vim/plugin directory

Debugging process

Use VIM to open the PHP file you want to debug, press to enter the debug state. Please step into the PHP debugging guide, which is written in more detail.

Precautions

In the actual process, if you find that the installation is still not working properly with PHP, it is most likely caused by the following reasons:

One, xdebug loading is not successful

You can confirm that the Xdebug was successfully loaded by phpinfo or "php-m". The reason for the unsuccessful loading may be that PHP is "Debug Build" (which can be confirmed by Phpinfo), so php.ini should not use "zend_extension=/ /xdebug.so" instead of "zend_ extension_debug=/ /xdebug.so ";

The other aspect is to pay attention to whether the xdebug.so path is correct, or if the Apache service or FASTCGI service is restarted.

The phpinfo display is displayed as follows, indicating normal

Second, the debugging session has expired

XDebug a cookie to determine if you are debugging a conversation, please note that this cookie expires in 1 hours. One day when you work in work, found Vim + xdebug just work, how do not work, it is mostly because this session has expired.

The debug session lasts 1 hours, as long as the parameter "Xdebug_session_start=1″" is appended to the URL.

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

Iv. Change the Debug wait time (default 5 seconds)

Edit debuger.py

2. Press and browse php file within 5 seconds. :-)
If you do setup correctly, server would make connection to vim.
[You can change the port by editing last line of Debugger.vim]

All the Windows currently opened would be closed and debugger interface would be shown.

3. In Debuggin mode
