php xdebug installation configuration and debugging php skills_PHP tutorial

xdebug is a high-level tool for PHP code execution. It can very well test the performance of each stage of our PHP code, so that we can optimize the code in a timely manner. Now I will give you 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. There are many versions, including the difference between 32-bit and 64-bit, the difference between VC6 and VC9, and the difference between thread safety and not

Save to test.php, and open the saved server directory through the browser. Find Compiler (if not, it is VC6), Architecture (if not, look at the value of Configure Command) and Thread Safety in the front Info. As shown below, you should download 32-bit VC9 thread-safe (PHP 5.3 VC9 TS (32 bit))

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

3. Configure Xdebug

Xdebug has many configuration items, and I only know a few of them, so I will only talk about the commonly used ones. 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

代码如下

复制代码

zend_extension="E:APMServPHPextphp_xdebug.dll" xdebug.auto_trace=On ;自动跟踪设置最好在最前面设置，要不然不会开启 xdebug.profiler_enable=on xdebug.trace_output_dir="E:APMServxdebug" xdebug.profiler_output_dir="E:APMServxdebug" ;最大递归数 xdebug.max_nesting_level=100 ;重写var_dump() xdebug.overload_var_dump = On ;当这个参数被设置为1时，即使捕捉到异常，xdebug仍将强制执行异常跟踪当一个异常出现时 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   ;允许远程连接 xdebug.remote_enable=true ;允许远程连接的zs IDE的ip地址       xdebug.remote_host=192.168.0.51 ;zendstudio 设定的端口 xdebug.remote_port=9000 ;zendstudio 的应用层通信协议 xdebug.remote_handler=dbgp xdebug.extended_info="1"

zend_extension="E:APMServPHPextphp_xdebug.dll"

xdebug.auto_trace=On

;It is best to set the automatic tracking setting at the front, otherwise it will not be turned on

xdebug.profiler_enable=on xdebug.trace_output_dir="E:APMServxdebug"

xdebug.profiler_output_dir="E:APMServxdebug"

;Maximum number of recursions

xdebug.max_nesting_level=100

;Rewrite var_dump()

代码如下	复制代码
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

xdebug.overload_var_dump = On ; When this parameter is set to 1, even if an exception is caught, xdebug will still force exception tracking 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 zs IDE that allows remote connection xdebug.remote_host=192.168.0.51 ;Port set by zendstudio xdebug.remote_port=9000 ;zendstudio’s 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 grows very fast, it will be one or two gigabytes in less than two days), so I commented out trace_output_dir and profiler_output_dir. It should be noted that Xdebug will not automatically create a directory, and you must ensure that the set directory is is actually there. As for the other several values, they are all default values, so they are noted out. Because they may be changed, they are listed here. Now refresh the phpinfo() page and you should be able to see the Xdebug information. linux xdebug configuration installation xdebug is a module of php that needs to be compiled and installed. I installed php using lnmp. php is installed to /usr/local/php by default, and then makes 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

Modify php.ini configuration

Add the following

;no-debug-non-zts-20090626 This folder name corresponds to the php version one-to-one

The code is as follows

代码如下

复制代码

;no-debug-non-zts-20090626 这个文件夹名称和php版本是一一对应的     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

Copy code

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 any php code with errors, refresh the browser, and you will see the error message
