forward_static_call_array —Call a static method and pass the arguments as array
Calls a user defined function or method given by thecallback parameter. This function must be called within a method context, it can't be used outside a class. It uses thelate static binding. All arguments of the forwarded method are passed as values, and as an array, similarly tocall_user_func_array().
callbackThe function or method to be called. This parameter may be anarray, with the name of the class, and the method, or astring, with a function name.
parameterOne parameter, gathering all the method parameter in one array.
Note:
Note that the parameters forforward_static_call_array() are not passed by reference.
Returns the function result, orfalse on error.
Example #1forward_static_call_array() example
<?php
classA
{
constNAME='A';
public static functiontest() {
$args=func_get_args();
echo static::NAME," ".join(',',$args)." \n";
}
}
classBextendsA
{
constNAME='B';
public static functiontest() {
echoself::NAME,"\n";
forward_static_call_array(array('A','test'), array('more','args'));
forward_static_call_array('test', array('other','args'));
}
}
B::test('foo');
functiontest() {
$args=func_get_args();
echo"C ".join(',',$args)." \n";
}
?>The above example will output:
BB more,args C other,args
Regarding namespaces:
Be sure to include fully namespaced class path:
<?php
forward_static_call_array(
array('NAMESPACE\CLASS_NAME','STATIC_METHOD'),
$params
);one of academic example, when forward_static_call() can be useful
<?php
classA
{
public static functiontest()
{
var_dump('we were here');
return static::class;
}
}
classBextendsA
{
public static functiontest()
{
returnself::class;
}
}
classCextendsB
{
public static functiontest()
{
$grandParent=get_parent_class(parent::class);// $grandParent is A
returnforward_static_call([$grandParent,__FUNCTION__]);// calls A::test()
}
}
// prints
// string(12) "we were here"
// string(1) "C"
var_dump(C::test());
