今天忽然想到的，就寫了一段測試php函數的代碼。

復制代碼 代碼如下:

<?php
/**
 * 參數數組$ParamList說明
 *
 * 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;
}

/**
 * 自動測試
 *
 * @param  string  $FunctionName  函數名稱
 * @param  array   $ParamList     參數列表
 * @return array
 */
function sysTestFunction($FunctionName, $ParamList)
{
    if(empty($FunctionName))
    {
        echo "函數名不能為空";
        return false;
    }
    if(!is_array(current($ParamList)))
    {
        echo "參數不是2維數組";
        return false;
    }
    $TestParamList = sysCombineArray($ParamList);
    echo "開始測試函數" . $FunctionName . "<br />";
    foreach($TestParamList as $Key => $TestParamInfo)
    {
        echo "開始測試第" . $Key . "組參數：<br />";
        foreach($TestParamInfo as $ParamKey => $Param)
        {
            ${"Param" . $ParamKey} = $Param;
            $TempParamList[] = "$Param" . $ParamKey;
            if(is_array($Param))
