<?php //定义Error_Handler 函数
/** * 定义Error_Handler 函数
 * * * @param $error_level 错误级别
 * * @param $error_message 错误信息
 * * @param $file 错误所在文件
 * * @param $line 错误所在行数
 * * */
//屏蔽程序中的错误
error_reporting (0);
set_error_handler("error_handler");
function error_handler ($error_level, $error_message, $file, $line) {
    echo "11111111111";
}
myerror_method();
?>

Copy after login


上面这段代码 调用了没定义的函数myerror_method(); 应该执行我的自定义错误处理函数error_handler()啊
奈何 echo "11111111111";这句没有执行啊,求大牛帮看下呢,跪谢!

------解决方案--------------------
你调用不存在函数,这是致命错误,直接导致脚本结束

你试试 echo $sakdfhgkjad;不存在的变量,则可正常调用自定义错误处理函数

BTW:
如果你非要在致命错误情况下,也能调用,则试试register_shutdown_function函数
------解决方案--------------------
php程序执行时有两个阶段
1、预编译阶段:完成对程序文件的语法分析,并生成中间代码
2、执行阶段:运行中间代码

set_error_handler("error_handler");
是在执行阶段执行的
所以不能处理预编译阶段的错误
