  作者:zhanhailiang 日期:2013-03-11

1.简述

引用官方描述:

The Xdebug extension helps you debugging your script by providing a lot of valuable debug information.

  |   NOTE: Please disregard the message                                 |

  |   that is emitted by the PECL installer. This does not work for      |
  |   Xdebug.                                                            |

# 修改php配置文件
################################################################
add the following line to php.ini: 
    zend_extension="/wherever/you/put/it/xdebug.so" 
    (for non-threaded use of PHP, for example the CLI, CGI or Apache 1.3 module)
or:
    zend_extension_ts="/wherever/you/put/it/xdebug.so" 
    (for threaded usage of PHP, for example the Apache 2 work MPM or the the ISAPI module). 
Note: In case you compiled PHP yourself and used --enable-debug you would have to
use zend_extension_debug=. From PHP 5.3 onwards, you always need to use the
zend_extension PHP.ini setting name, and not zend_extension_ts, nor zend_extension_debug.
However, your compile options (ZTS/normal build; debug/non-debug) still need to match
with what PHP is using.

3.测试用例

简单的测试用例如下:

header( 'X-Test: Testing' );
setcookie( "TestCookie", "test-value" );
var_dump( xdebug_get_headers() );

输出如下:

array(2) {
  [0] =>
  string(15) "X-Test: Testing"
  [1] =>
  string(33) "Set-Cookie: TestCookie=test-value"
}

高级测试用例――查看变量的zval值

$a = array(1, 2, 3);
$b =& $a;
$c =& $a[2];
 
xdebug_debug_zval('a');

输出如下:

a: (refcount=2, is_ref=1)=array(3) {
  [0] =>
(refcount=1, is_ref=0)=  int(1)
  [1] =>
(refcount=1, is_ref=0)=  int(2)
  [2] =>
(refcount=2, is_ref=1)=  int(3)
}

开始Xdebug之旅吧,少年!【Documentation for: Xdebug 2】
