-
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:
handler ( resource $parser , string $data )- parser
- The first parameter, parser, is a reference to the XML parser calling the handler.
- data
- The second parameter, data , contains the character data as a string.
Character data handler is called for every piece of a text in the XML document. It can be called multiple times inside each fragment (e.g. for non-ASCII strings).
If a handler function is set to an empty string, or FALSE, the handler in question is disabled.
Note: 除了函式名稱，還可以用一個包含物件參照和方法名稱的陣列作參數。
