示例
示例 #1 使用 set_error_handler() 函数将错误信息托管至 ErrorException。
<?php
function exception_error_handler($severity, $message, $file, $line) {
if (!(error_reporting() & $severity)) {
// 这个错误代码未包含在 error_reporting 中
return;
}
throw new ErrorException($message, 0, $severity, $file, $line);
}
set_error_handler("exception_error_handler");
/* 触发异常 */
strpos();
?>以上示例的输出类似于：
Fatal error: Uncaught exception 'ErrorException' with message 'strpos() expects at least 2 parameters, 0 given' in /home/bjori/tmp/ex.php:12
Stack trace:
#0 [internal function]: exception_error_handler(2, 'strpos() expect...', '/home/bjori/php...', 12, Array)
#1 /home/bjori/php/cleandocs/test.php(12): strpos()
#2 {main}
thrown in /home/bjori/tmp/ex.php on line 12
