(PHP 4 >= 4.0.5, PHP 5)
call_user_method_array — 调用一个用户方法，同时传递参数数组（已废弃）
call_user_method_array() 函数自 PHP 4.1.0 起已废弃，使用 call_user_func_array() 函数和 array(&$obj, "method_name") 语法代替。
从用户定义的 obj
对象中调用 method_name
所指的方法，同时使用 paramarr
中的参数。

You don't have to write a new function, <?php call_user_func_array(array($obj, $method_name), $params); ?> works pretty fine! (to my mind, 'eval' fucntion should be avoided almost all the time)

<?php
/**
* @param string $func - method name
* @param object $obj - object to call method on
* @param boolean|array $params - array of parameters
*/
function call_object_method_array($func, $obj, $params=false){
if (!method_exists($obj,$func)){
// object doesn't have function, return null
return (null);
}
// no params so just return function
if (!$params){
return ($obj->$func());
}
// build eval string to execute function with parameters
$pstr='';
$p=0;
foreach ($params as $param){
$pstr.=$p>0 ? ', ' : '';
$pstr.='$params['.$p.']';
$p++;
}
$evalstr='$retval=$obj->'.$func.'('.$pstr.');';
$evalok=eval($evalstr);
// if eval worked ok, return value returned by function
if ($evalok){
return ($retval);
} else {
return (null);
}
return (null);
}
?>

If you this function will be deleted in future php releases you can use this function:
<?
function _call_user_method_array($name, $obj, $params) {
// get params
$txt = "";
foreach($params as $nr => $el) {
$txt.='$params['.$nr."], ";
}
$txt = substr($txt, 0, strlen($txt)-2);
// run it
return eval('return call_user_method($name, $obj, '.$txt.');');
}
?>
Hope this helps somebody.
