Php xdebug installation, configuration, and debugging skills

Xdebug is a php code execution tool that can test the performance of each stage of our php code, so that we can optimize the number of code in a timely manner, next I will give you the xdebug and xdebug debugging skills.

Windows xdebug configuration and installation

1. Download Xdebug

: Http://xdebug.org/download.php
The latest version is 2.1.2 and has many versions. There are 32-bit and 64-bit differences, the differences between VC6 and VC9, and the difference in thread security.

<? PHP phpinfo ();?> Save to test. php, save the server directory, and open it in a browser. Find Compiler (VC6 if not), Architecture (the value of Configure Command if not), and Thread Safety in the previous Info. For example, you should download a 32-bit VC9 thread safe (PHP 5.3 VC9 TS (32 bit ))

2. Install Xdebug
If you have configured PHP, change the downloaded file to php_xdebug.dll (it doesn't matter if you don't change it, just to look good), and put down the ext folder in the PHP installation directory.

3. Configure Xdebug

Xdebug has many configuration projects, so I only know a few of them. Modify the PHP. ini file in the php installation directory and insert the following code at the end of the file:
[Xdebug]

The Code is as follows:

Copy code

Zend_extension = "E: APMServPHPextphp_xdebug.dll" Xdebug. auto_trace = On ; It is best to set automatic tracking at the beginning, otherwise it will not be enabled Xdebug. profiler_enable = on Xdebug. trace_output_dir = "E: APMServxdebug" Xdebug. profiler_output_dir = "E: APMServxdebug" ; Maximum number of Recursion Xdebug. max_nesting_level = 100 ; Override var_dump () Xdebug. overload_var_dump = On When this parameter is set to 1, xdebug enforces exception tracking even if an exception is caught. Xdebug. show_exception_trace = 1   Xdebug. show_local_vars = 1 Xdebug. collect_params = On Xdebug. collect_return = On Xdebug. collect_vars = On Xdebug. dump_undefined = On Xdebug. profiler_enable_trigger = On   ; Allow remote connection Xdebug. remote_enable = true ; IP address of the zs IDE that allows remote connection Xdebug. remote_host = 192.168.0.51 Zendstudio Port Xdebug. remote_port = 9000 Zendstudio application layer communication protocol Xdebug. remote_handler = dbgp Xdebug. extended_info = "1"

Because I don't want to have a Log file (because the file is growing fast and has a GB or two days later), I commented out trace_output_dir and profiler_output_dir, note that Xdebug does not automatically create a directory. You must ensure that the directory actually exists. As for the other items, they are all default values. Therefore, the values are listed because they may be changed. Now, refresh the phpinfo () page to see the Xdebug information.

Linux xdebug configuration and installation

Xdebug is a module of php and needs to be compiled and installed. php installed with lnmp is installed to/usr/local/php by default, and a hard link to/usr/bin is made.

Compile xdebug first

The Code is as follows:	Copy code
Wget http://www.xdebug.org/files/xdebug-2.2.3.tgz Tar xzf xdebug-2.2.3.tgz Cd xdebug-2.2.3 /Usr/bin/phpize ./Configure -- with-php-config =/usr/local/php/bin/php-config

Modify php. ini configuration

Add the following

The Code is as follows:

Copy code

; No-debug-non-zts-20090626 this folder name and php version are one-to-one correspondence Zend_extension = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/xdebug. so" Xdebug. default_enable = On Xdebug. show_exception_trace = On Xdebug. show_local_vars = 1 Xdebug. max_nesting_level = 50 Xdebug. var_display_max_depth = 6 Xdebug. dump_once = On Xdebug. dump_globals = On Xdebug. dump_undefined = On Xdebug. dump. REQUEST = * Xdebug. cli_color = 2

Restart php-fpm, write the wrong php code at will, and refresh the browser to see the error prompt.
