Vim+xdebug Debugging PHP

1 Installing the PHP debugging environment

After installing Php-devel, there will be phpize and php-config scripts.

Yum installphp-devel.x86_64

2 Installing Xdebug2.1 Installation

Installing with Yum may fail with PECL installation success.

#yum installphp-pecl-xdebug.x86_64

Pecl Installxdebug

2.2 Modify Permissions

Assigning shared libraries xdebug.so Execute permissions

chmod +x/usr/lib64/php/modules/xdebug.so

2.3 Modifying the PHP configuration

To create a new profile Xdebug.ini (or append directly to php.ini) under/ETC/PHP.D, add the following:

===============================================================================

[Xdebug]
Xdebug.defalut_enable=on
Zend_extension =/home/rong/php-5.5.16/lib/php/extensions/no-debug-non-zts-20121212/xdebug.so
zend_debugger.allow_hosts=127.0.0.1
Zend_debugger.expose_remotely=always
Zend_debugger.httpd_uid=-1
Xdebug.auto_trace = On
Xdebug.auto_profile = On
Xdebug.collect_params = On
Xdebug.collect_return = On
Xdebug.profiler_enable = On
Xdebug.trace_output_dir = "/tmp"
Xdebug.profiler_output_dir = "/tmp"
Xdebug.dump.GET = *
Xdebug.dump.POST = *
Xdebug.dump.COOKIE = *
Xdebug.dump.SESSION = *
Xdebug.var_display_max_data = 4056
Xdebug.var_display_max_depth = 5
Xdebug.remote_enable=on
Xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9010
Xdebug.remote_autostart=1

===============================================================================

Red is the key content, configure the location of the xdebug.so, and enable Xdebug to open the remote debugging mode. Remote_port a must be consistent with the VIM configuration or IDE configuration that will be mentioned later.

2.4 Verifying that the installation was successful

Visit the test page http://localhost/test.php to see if Xdebug is included in the output of the Phpinfo () function.

3 Installing the VIM Debug Plugin 3.1 download installation

VIM supports Xdebug for plugins in this:

http://www.vim.org/scripts/script.php?script_id=1929

After decompression, copy the plugin folder in the plugin to xxx/vim/plugins/.

Cp–r debugger/* xxx/vim/plugins/

3.2 Modifying the default port

Under/home/user, create a new. vimrc file, and join the configuration as follows:

Let G:debuggerport = 9010

Note: Be consistent with the port configuration in Xdebug.ini.

4 Debugging examples

Take/export/data/discuz/test.php as an example (/export/data/discuz is my discuz! x root directory).

test.php content is as follows:

===============================================================================

<?php

Phpinfo ();

$name = "Cdai";

Print ("Hello {$name}");

?>

===============================================================================

Open test.php with vim and switch to print ("Hello {$name}"); This line, input : Bp command plus breakpoint.

Press F5 to start listening, which requires a browser to access the test.php page within five seconds.

Http://localhost/test.php?XDEBUG_SESSION_START=1

Note: Be sure to add the xdebug_session_start=1 parameter to the URL to turn on debugging.

When you enter a URL, the call stops at the breakpoint line. As follows:
