xml_set_default_handler
Set up default handler
Description
true xml_set_default_handler(XMLParser $parser, callable $handler)
Parameters
-
parser
-
The XML parser.
-
handler
-
If null is passed, the handler is reset to its default state.
Warning
An empty string will also reset the handler,
however this is deprecated as of PHP 8.4.0.
If handler is a callable,
the callable is set as the handler.
If handler is a string,
it can be the name of a method of an object set with
xml_set_object.
Warning
This is deprecated as of PHP 8.4.0.
Warning
As of PHP 8.4.0, the callable is checked to be valid while setting the handler,
not when it is called.
This means that xml_set_object must be called prior to
setting a method string as the callback.
However, as this behaviour is also deprecated as of PHP 8.4.0,
using a proper callable for the method is recommended instead.
The signature of the handler must be:
void handler(XMLParser $parser, string $data)
-
parser
-
The XML parser calling the handler.
-
data
-
data contains the character data.
This may be the XML declaration, document type declaration,
entities or other data for which no other handler exists.
Return Values
Always returns true.
