Description

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

Aviso

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");
?>
