php扩展xdebug基本使用

官网:http://www.xdebug.org/ 使用:http://www.xdebug.orgPHP
强烈推介IDEA2020.2破解激活,IntelliJ IDEA 注册码,2020.2 IDEA 激活码

官网:http://www.xdebug.org/ 

使用:http://www.xdebug.org/docs/

 

安装

http://blog.csdn.net/21aspnet/article/details/7036087

 

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() 
<?php
header( "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()

<?php
echo 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 = 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.dump.SERVER = REQUEST_METHOD,REQUEST_URI,HTTP_USER_AGENT

xdebug.trace_format = 0
xdebug.auto_trace = On
xdebug.trace_output_dir = E:\xampp\tmp\traces
xdebug.trace_output_name = trace.%c.%p

xdebug.collect_params = 4
xdebug.collect_includes = On
xdebug.collect_return = On
xdebug.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]
