今天忽然想到的，就寫了一段測試php函數的代碼。

<?php

/**

 *
 * 數組的第一維索引是需要測試的函數的參數名，第二維的每個元素是該參數需要測試的可能值，元素值可以為數組。
 */

$ParamList = array("Param1" => array(3,4,3,2,1),
                   "Param2" => array(3,2,5),
                   "Param3" => array(0,0.5,1,1.5));

// 測試函數
sysTestFunction("Test", $ParamList);

// 待測試的函數
function Test($Param1, $Param2, $Param3)
{
    return $Param1 . "|" . $Param2 . "|" . $Param3;
}
