属性

severity: 异常级别

范例

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();
?>

以上例程的输出类似于：

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
