call_user_method_array — 调用一个用户方法,同时传递参数数组(已废弃)
$method_name
, object &$obj
, array $paramarr
)call_user_method_array() 函数自 PHP 4.1.0 起已废弃,使用 call_user_func_array() 函数和 array(&$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。
参见 call_user_func_array() 和 call_user_func() 。

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
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);
}
