PHP xdebug 帮助调试php 程序

以下步骤为使用source 包去安装xdebug软件包。

#tar xzf xdebug-2.1.0.tgz

#cd xdebug-2.1.0

#phpize

#./configure --enable-xdebug (如果提示找不到php-config ；则请用以下命令编译：./configure --enable-xdebug --with-php-config=/usr/local/php/bin/php-config)

#make && make install

#vi /etc/php.ini

增加以下行：

zend_extension=/usr/lib/php/modules/xdebug.so

把显示错误项打开：

error_reporting  =  E_ALL

display_errors = On

 

保存。

重启apache，即可。
