上述代码中，有个'errorHandlerException'类，该类放在文件'errorHandlerException.class.php'中，该类用于将错误转换为异常，以便记录错误发生的文件、行号、错误代码、错误信息等信息，同时其方法'isFatalError'用于辨别该错误是否是致命性错误。这里我们为了方便管理，将错误进行编号并命名。该类的代码如下
/** * 文件名称：errorHandlerException.class.php * 摘 要：自定义错误异常类 该类继承至PHP内置的错误异常类 */ class errorHandlerException extends ErrorException { public static $localCode = array( E_COMPILE_ERROR => 4001, E_COMPILE_WARNING => 4002, E_CORE_ERROR => 4003, E_CORE_WARNING => 4004, E_DEPRECATED => 4005, E_ERROR => 4006, E_NOTICE => 4007, E_PARSE => 4008, E_RECOVERABLE_ERROR => 4009, E_STRICT => 4010, E_USER_DEPRECATED => 4011, E_USER_ERROR => 4012, E_USER_NOTICE => 4013, E_USER_WARNING => 4014, E_WARNING => 4015, 4016 => 4016, ); public static $localName = array( E_COMPILE_ERROR => 'PHP Compile Error', E_COMPILE_WARNING => 'PHP Compile Warning', E_CORE_ERROR => 'PHP Core Error', E_CORE_WARNING => 'PHP Core Warning', E_DEPRECATED => 'PHP Deprecated Warning', E_ERROR => 'PHP Fatal Error', E_NOTICE => 'PHP Notice', E_PARSE => 'PHP Parse Error', E_RECOVERABLE_ERROR => 'PHP Recoverable Error', E_STRICT => 'PHP Strict Warning', E_USER_DEPRECATED => 'PHP User Deprecated Warning', E_USER_ERROR => 'PHP User Error', E_USER_NOTICE => 'PHP User Notice', E_USER_WARNING => 'PHP User Warning', E_WARNING => 'PHP Warning', 4016 => 'Customer`s Error', ); /** * 方 法：构造函数 * 摘 要：相关知识请查看 * * 参 数：string $message 异常信息(可选) * int $code 异常代码(可选) * int $severity * string $filename 异常文件(可选) * int $line 异常的行数(可选) * Exception $previous 上一个异常(可选) * * 返 回：void */ public function __construct($message = '', $code = 0, $severity = 1, $filename = __FILE__, $line = __LINE__, Exception $previous = null) { parent::__construct($message, $code, $severity, $filename, $line, $previous); } /** * 方 法：是否是致命性错误 * 参 数：array $error * 返 回：boolean */ public static function isFatalError($error) { $fatalErrors = array( E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING ); return isset($error['type']) && in_array($error['type'], $fatalErrors); } /** * 方 法：根据原始的错误代码得到本地的错误代码 * 参 数：int $code * 返 回：int $localCode */ public static function getLocalCode($code) { return isset(self::$localCode[$code]) ? self::$localCode[$code] : self::$localCode[4016]; } /** * 方 法：根据原始的错误代码获取用户友好型名称 * 参 数：int * 返 回：string $name */ public static function getName($code) { return isset(self::$localName[$code]) ? self::$localName[$code] : self::$localName[4016]; }
