小编ajn*_*ari的帖子

我一直在使用PHP一段时间,但我偶然发现了一些我无法做出正面或反面的事情.这是我在这里发现的帖子(我相信已被锁定),我理解大部分解决方案,但只有一部分我很困惑.

  if ( ( $number & $error_number ) == $number )
  {
    $error_description[ ] = $description;
  }

我不太确定在这里检查什么.任何帮助表示赞赏.

((完整代码))

<?php

$error_number = 22527; //could also use ini_get('error_reporting')
$error_description = array( );
$error_codes = array(

    E_WARNING            => "E_WARNING",
    E_PARSE              => "E_PARSE",
