An example of usage of php's call_user_func_array() function

function debug($var, $val)
{
echo "***DEBUGGINGnVARIABLE: $varnVALUE:";
if (is_array($val) || is_object ($val) || is_resource($val)) {
print_r($val);
} else {
echo "n$valn";
}
echo "***n";
}
$c = mysql_connect();
$host = $_SERVER["SERVER_NAME"];
call_user_func_array('debug', array("host", $host)) ;
call_user_func_array('debug', array("c", $c));
call_user_func_array('debug', array("_POST", $_POST));
?>

function test($str) {
echo $str;
}
call_user_func_array("test" ,"NO.1 www.chhua.com");//Output "NO.1 www.chhua.com"
//Parameter description "The first parameter is the function name, the second is the parameter
class testClass {
 public function write($str){
echo $str;
}
}
call_user_func_array(array(testClass,write),"NO.1 www.chhua.com");//When calling with a class, use array (), array (class name, method name)
?>
