Описание

bool xml_set_unparsed_entity_decl_handler ( resource $parser , callback $handler )

Sets the unparsed entity declaration handler function for the XML parser parser .

The handler will be called if the XML parser encounters an external entity declaration with an NDATA declaration, like the following:


<!ENTITY <parameter>name</parameter> {<parameter>publicId</parameter> | <parameter>systemId</parameter>}
        NDATA <parameter>notationName</parameter>

See » section 4.2.2 of the XML 1.0 spec for the definition of notation declared external entities.

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 six parameters:

handler ( resource $parser , string $entity_name , string $base , string $system_id , string $public_id , string $notation_name )

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
entity_name: The name of the entity that is about to be defined.
base: This is the base for resolving the system identifier (systemId ) of the external entity.Currently this parameter will always be set to an empty string.
system_id: System identifier for the external entity.
public_id: Public identifier for the external entity.
notation_name: Name of the notation of this entity (see xml_set_notation_decl_handler()).

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

Note: В качестве аргумента вместо имени функции может быть передан массив, содержащий ссылку на объект и имя метода.
