警告

Unix style paths with forward slashes can cause significant performance degradation on Windows systems; be sure to call realpath() in such a case.

參數(shù)

filename

The path to the XML document.

options

Bitwise OR of the libxml option constants.

返回值

成功時(shí)返回 true， 或者在失敗時(shí)返回 false。 If called statically, returns a DOMDocument 或者在失敗時(shí)返回 false.

錯(cuò)誤／異常

If an empty string is passed as the filename or an empty file is named, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

在 PHP 8.0.0 之前可以靜態(tài)調(diào)用此方法，但會(huì)發(fā)出 E_DEPRECATED 錯(cuò)誤。自 PHP 8.0.0 起，靜態(tài)調(diào)用此方法會(huì)拋出 Error 異常
