The XML parser.
handler
If null
is passed, the handler is reset to its default state.
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().
This is deprecated as of PHP 8.4.0.
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.

Versión | Descripción |
---|---|
8.4.0 |
Passing a non-callable string to
handler is now deprecated,
use a proper callable for methods, or null to reset the handler.
|
8.4.0 |
The validity of handler as a callable
is now checked when setting the handler instead of checking when calling it.
|
8.0.0 |
parser expects an XMLParser
instance now; previously, a valid xml resource was expected.
|
7.3.0 |
El valor de retorno de handler ya no es
ignorado cuando la extensión ha sido compilada contra libxml. Anteriormente,
el valor de retorno era ignorado y el análisis nunca se detenía.
