PHP xdebug installation configuration and debugging PHP tips _php Tutorial

Xdebug is a PHP code execution height tool, it can test the performance of our PHP code at all stages, so that we can do several code optimization in a timely manner, the following I will give you from the configuration of Xdebug and Xdebug debugging skills.

Windows Xdebug Configuration Installation

1. Download Xdebug

Download Address: http://xdebug.org/download.php
The latest version is 2.1.2, with many versions, with 32-bit and 64-bit differences, differences between VC6 and VC9, and thread safety or not.

Save to test.php, save the server directory, open through the browser. In the first info, find compiler (no VC6), Architecture (not the value of Configure command) and thread Safety. For example, you should download the 32-bit VC9 thread-safe (PHP 5.3 VC9 TS (three bit))

2. Installing Xdebug
If you've already configured PHP, rename the downloaded file to Php_xdebug.dll (it doesn't matter, just to look good), put down the Ext folder of the PHP installation directory.

3. Configure Xdebug

Xdebug a lot of configuration items, I only know a very small part, so just talk about the usual. To modify the PHP installation directory's php.ini file, 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 Auto-tracking settings are best set at the front, otherwise they won't turn on Xdebug.profiler_enable=on Xdebug.trace_output_dir= "E:apmservxdebug" Xdebug.profiler_output_dir= "E:apmservxdebug" ; Maximum recursive number xdebug.max_nesting_level=100 ; rewrite Var_dump () Xdebug.overload_var_dump = On When this parameter is set to 1 o'clock, Xdebug will still force exception tracking even if an exception is caught when an exception occurs 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 connections Xdebug.remote_enable=true The IP address of the ZS IDE that allows remote connections xdebug.remote_host=192.168.0.51 ; Zendstudio set the port xdebug.remote_port=9000 ; Zendstudio application-Layer communication protocol Xdebug.remote_handler=dbgp xdebug.extended_info= "1"

Because I do not want to have a log file (because the file grows fast, not two days there is one or two g), so the Trace_output_dir and Profiler_output_dir commented out, to note that Xdebug will not automatically build the directory, You must ensure that the set directory is actually present. As for the others, it is the default value, so the note is dropped, because it may change, so the column comes out. Now refresh the phpinfo () page, you should be able to see the xdebug information.

Linux Xdebug Configuration Installation

Xdebug is a module of PHP, need to compile the installation, I use LNMP installed php,php is installed by default to/usr/local/php, and then do a hard link to/usr/bin

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

Modifying the php.ini configuration

Add the following to the

The code is as follows

Copy Code

no-debug-non-zts-20090626 this folder name and PHP version are one by one corresponding 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, refresh the browser, you can see the error message
