xml_set_end_namespace_decl_handler — 建立終止命名空間聲明處理器

說明

xml_set_end_namespace_decl_handler(resource $parser, callable $handler): bool

Set a handler to be called when leaving the scope of a namespace declaration. This will be called, for each namespace declaration, after the handler for the end tag of the element in which the namespace was declared.

參數(shù)

parser

A reference to the XML parser.

handler

handler is a string containing the name of a function that must exist when xml_parse() is called for parser.

The function named by handler must accept two parameters, and should return an integer value. If the value returned from the handler is false (which it will be if no value is returned), the XML parser will stop parsing and xml_get_error_code() will return XML_ERROR_EXTERNAL_ENTITY_HANDLING.

handler(resource $parser, string $prefix)
parser
The first parameter, parser, is a reference to the XML parser calling the handler.
prefix
The prefix is a string used to reference the namespace within an XML object.

If a handler function is set to an empty string, or false, the handler in question is disabled.

注意: 除了函數(shù)名，含有對(duì)象引用的數(shù)組和方法名也可以作為參數(shù)。

返回值

成功時(shí)返回 true， 或者在失敗時(shí)返回 false。
