php扩展xdebug基本使用

来源:互联网 发布:电信光猫iptv端口连接 编辑:程序博客网 时间:2024/05/17 23:55

官网:http://www.xdebug.org/ 

使用:http://www.xdebug.org/docs/

 

安装

使用

 

1.获取文件名,行号,函数名

xdebug_call_class()

<?php
    function fix_string($a)
    {
        echo "Called @ ".
            xdebug_call_file().
            ":".
            xdebug_call_line().
            " from ".
            xdebug_call_function();
    }

    $ret = fix_string(array('Derick'));
?>


输出:

Called @ /var/www/xdebug_caller.php:12 from {main}
 
2.输出head信息
xdebug_get_headers() 
<?phpheader( "X-Test", "Testing" );setcookie( "TestCookie", "test-value" );var_dump( xdebug_get_headers() );?>


输出:

array(2) {  [0]=>  string(6) "X-Test"  [1]=>  string(33) "Set-Cookie: TestCookie=test-value"}

 

 

3.输出执行时间

xdebug_time_index()

<?phpecho xdebug_time_index(), "\n";for ($i = 0; $i < 250000; $i++){    // do nothing}echo xdebug_time_index(), "\n";?>

4.代码覆盖

xdebug_start_code_coverage();

代码

var_dump(xdebug_get_code_coverage());

看图更明显

 

5.代码跟踪

需要跟踪的代码:

class myClass{    public function a($a) {        echo $a * 2.5;    }    public function b($b) {       $this->a($b + 2);    }}xdebug_start_trace('trace');$obj=new myClass();$obj->b(6);echo "</br>";xdebug_stop_trace();

--------------------------------------------------------------------------
xdebug配置参考

xdebug.default_enable = Onxdebug.show_exception_trace = Onxdebug.show_local_vars = 1xdebug.max_nesting_level = 50xdebug.var_display_max_depth = 6xdebug.dump_once = Onxdebug.dump_globals = Onxdebug.dump_undefined = Onxdebug.dump.REQUEST = *xdebug.dump.SERVER = REQUEST_METHOD,REQUEST_URI,HTTP_USER_AGENTxdebug.trace_format = 0xdebug.auto_trace = Onxdebug.trace_output_dir = E:\xampp\tmp\tracesxdebug.trace_output_name = trace.%c.%pxdebug.collect_params = 4xdebug.collect_includes = Onxdebug.collect_return = Onxdebug.show_mem_delta = On

设置xdebug.auto_trace = Off可在代码中添加xdebug_start_trace();xdebug_stop_trace();语句生成追踪文件。


使用xdebug_start_trace跟踪代码执行

xdebug_start_trace('trace');$a->myCaller($b);xdebug_stop_trace();TRACE START [16:53:57]0.0010      57964    -> MyClass->myCaller() /code/xdebug.php:210.0011      58104     -> MyOther->myCallee() /code/xdebug.php:40.0011      58104      -> xdebug_call_class() /code/xdebug.php:100.0011      58128      -> printf() /code/xdebug.php:100.0014      58196      -> xdebug_call_function() /code/xdebug.php:110.0015      58196      -> printf() /code/xdebug.php:110.0016      58196      -> xdebug_call_file() /code/xdebug.php:120.0016      58244      -> printf() /code/xdebug.php:120.0017      58244      -> xdebug_call_line() /code/xdebug.php:130.0017      58244      -> printf() /code/xdebug.php:130.0018      58244   -> xdebug_stop_trace() /code/xdebug.php:220.0019      58244TRACE END [16:53:57]
