xml_set_processing_instruction_handler

(PHP 4, PHP 5)

xml_set_processing_instruction_handler Set up processing instruction (PI) handler

설명

bool xml_set_processing_instruction_handler ( resource $parser , callback $handler )

Sets the processing instruction (PI) handler function for the XML parser parser .

A processing instruction has the following format:

<?target data?>

You can put PHP code into such a tag, but be aware of one limitation: in an XML PI, the PI end tag (?>) can not be quoted, so this character sequence should not appear in the PHP code you embed with PIs in XML documents.If it does, the rest of the PHP code, as well as the "real" PI end tag, will be treated as character data.

인수

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 three parameters:

handler ( resource $parser , string $target , string $data )

parser
The first parameter, parser, is a reference to the XML parser calling the handler.
target
The second parameter, target , contains the PI target.
data
The third parameter, data , contains the PI data.

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

Note: 함수 이름 대신에, 객체의 참조와 메쏘드 이름을 가지는 배열을 사용할 수 있습니다.

반환값

성공할 경우 TRUE를, 실패할 경우 FALSE를 반환합니다.
