note 98012 added to function.call-user-method-array

Small, but necessary change:

Remember: eval returns null, unless return is called within eval'd string.
So check, that result is not false (bool).

Hint:
Using classes that gets functionality from external sources, i.e. SoapClient, which gets functions from wdsl, the method_exists -check in the beginning will fail.
Maybe you want to add a parameter to the function to supress the check that method exists.

<?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 ($evalok !== false){
        return ($retval);
    } else {
        return (null);
    }       
    return (null);  
}
