<?php

//配置文件数据值获取。
//默认没有第三个参数时,按照字符串读取提取&#39;&#39;中或""中的内容
//如果有第三个参数时为int时按照数字int处理。
function getconfig($file, $ini, $type="string")
{
	if ($type=="int")
	{
		$str = file_get_contents($file);
		$config = preg_match("/" . $ini . "=(.*);/", $str, $res);
		Return $res[1];
	}
	else
	{
		$str = file_get_contents($file);
		$config = preg_match("/" . $ini . "=\"(.*)\";/", $str, $res);
		if($res[1]==null)
		{	
			$config = preg_match("/" . $ini . "=&#39;(.*)&#39;;/", $str, $res);
		}
		Return $res[1];
	}
} 

//配置文件数据项更新
//默认没有第四个参数时,按照字符串读取提取&#39;&#39;中或""中的内容
//如果有第四个参数时为int时按照数字int处理。
function updateconfig($file, $ini, $value,$type="string")

	$str = file_get_contents($file);
	$str2="";
	if($type=="int") 
	{	
		$str2 = preg_replace("/" . $ini . "=(.*);/", $ini . "=" . $value . ";", $str);

//echo getconfig("./2.php", "bb", "string");
getconfig("./2.php", "bb");//
updateconfig("./2.php", "kkk", "admin");
