DOMDocument::load — Load XML from a file
Loads an XML document from a file.
Unix style paths with forward slashes can cause significant performance degradation on Windows systems; be sure to call realpath() in such a case.
成功时返回 TRUE， 或者在失败时返回 FALSE。 If called statically, returns a
DOMDocument 或者在失败时返回 FALSE.
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.
此方法可以被静态调用,但会抛出一个 E_STRICT 错误。
