<?php
function foobar($arg, $arg2) {
echo __FUNCTION__, " got $arg and $arg2\n";
}
class foo {
function bar($arg, $arg2) {
echo __METHOD__, " got $arg and $arg2\n";
}
}
// Call the foobar() function with 2 arguments
call_user_func_array("foobar", array("one", "two"));
// Call the $foo->bar() method with 2 arguments
$foo = new foo;
call_user_func_array(array($foo, "bar"), array("three", "four"));
?>以上例程的输出类似于：
foobar got one and two foo::bar got three and four
Example #2 call_user_func_array() using namespace name
<?php
namespace Foobar;
class
Foo {
static public function test($name) {
print "Hello {$name}!\n";
}
}
// As of PHP 5.3.0
call_user_func_array(__NAMESPACE__ .'\Foo::test', array('Hannes'));
// As of PHP 5.3.0
call_user_func_array(array(__NAMESPACE__ .'\Foo', 'test'), array('Philip'));
?>以上例程的输出类似于：
Hello Hannes! Hello Philip!
Example #3 Using lambda function
<?php
$func
= function($arg1, $arg2) {
return $arg1 * $arg2;
};
var_dump(call_user_func_array($func, array(2, 4))); /* As of PHP 5.3.0 */
?>以上例程会输出：
int(8)
