PHP Manual: call_user

Description

mixed call_user_method ( string method_name, object &obj [, mixed parameter [, mixed ...]] )

Warning

The call_user_method() function is deprecated as of PHP 4.1.0, use the call_user_func() variety with the array(&$obj, "method_name") syntax instead.

Calls the method referred by method_name from the user defined obj object. An example of usage is below, where we define a class, instantiate an object and use call_user_method() to call indirectly its print_info method.

<?php
class Country {
    var $NAME;
    var $TLD;
    
    function Country($name, $tld) 
    {
        $this->NAME = $name;
        $this->TLD = $tld;
    }

    function print_info($prestr = "") 
    {
        echo $prestr . "Country: " . $this->NAME . "\n";
        echo $prestr . "Top Level Domain: " . $this->TLD . "\n";
    }
}

$cntry = new Country("Peru", "pe");

echo "* Calling the object method directly\n";
$cntry->print_info();

echo "\n* Calling the same method indirectly\n";
call_user_method("print_info", $cntry, "\t");
?>
