The official manual gives the following example:

Copy code The code is as follows:

// Use Example of NameSpace
namespace Foobar;
class Foo {
static public function test() {
print "Hello world!n";
}
}
call_user_func( __NAMESPACE__ .'Foo::test'); // As of PHP 5.3.0
// Hello world!
call_user_func(array(__NAMESPACE__ .'Foo', 'test')); // As of PHP 5.3.0
// Hello world!
?>

Copy code The code is as follows:

// Example of direct method calling
class myclass {
static function say_hello()
{
echo "Hello!n";
}
}
$classname = "myclass";
call_user_func(array($classname, 'say_hello'));
call_user_func($classname .'::say_hello'); // As of 5.2.3
?>

So, what if it is an ordinary method and the method has parameters?
The following is a small example written by the author for reference:
Copy the code The code is as follows:

//Execute the class with parameters
class Loveapple{
public function sayHello($a, $b){
echo "Hello:".$a.". " .$b."n";

}
}
$obj = new Loveapple();
//Execution result Hello: loveapple. Using instance.
call_user_func(array ($obj, "sayHello"), "loveapple", "Using instance.");
//Execution result Hello:loveapple. Using class name.
call_user_func(array("Loveapple", "sayHello") , "loveapple", "Using class name.");
?>
