php如何自定义错误处理

set_error_handler(errorhandler,E_ALL|E_STRICT);

function my_define_error(errCode,errCode,errCode,errMsg,errFile,errFile,errFile,errLine){
    函数内部写入处理错误的代码
}

<?php // 用户定义的错误处理函数
 function myErrorHandler($errno, $errstr, $errfile, $errline) {
     echo "<b>Custom error:</b> [$errno] $errstr<br>";
     echo " Error on line $errline in $errfile<br>";
 } // 设置用户定义的错误处理函数
 set_error_handler("myErrorHandler");

 $test=2; // 触发错误
 if ($test>1) {
     trigger_error("A custom error has been triggered");
 }
 ?>

Custom error: [1024] A custom error has been triggered
 Error on line 14 in C:\webfolder\test.php
