我想实现一个输入不同的IP地址并提交后，在“您是第...位访客”中显示相应IP访问了多少次。。。我用一个TXT文件存储IP地址与浏览次数，格式如下：
例：
192.168.0.22 5
192.168.5.44 10
......

这个程序应该如何修改？

<?php// 访客计数器函数function counter() {		!empty($_GET['weburl'])  ||  die('weburl不能为空');	$weburl = trim($_GET['weburl']);	$pattern = "/((25[0-5]|2[0-4]\d|1?\d?\d)\.){3}(25[0-5]|2[0-4]\d|1?\d?\d)/";	//对录入的ip格式进行判断	if(! preg_match($pattern,$weburl))		die('IP地址格式不正确;');	//使ip长度固定	$arr = explode('.',$weburl);	for($i=0;$i<4;$i++){		$arr[$i] = str_pad($arr[$i],3,' ',STR_PAD_LEFT);			}	$weburl = join('.',$arr);	$file = 'counter.txt';	if (! file_exists($file)) {		$num = 1;		$cf = fopen($file, 'w');		fwrite($cf, $weburl.'-'.$num);		fclose($cf);		return $num;	} else {		$cf = fopen($file, 'r+');		while(!feof ($cf)){			$str1 = fgets($cf);			$str2 = substr($str1,0,strpos($str1,'-'));			if($weburl == $str2){				$len = strlen($str1);				$num = (int) trim(substr($str1,strpos($str1,'-')+1));								$num++;								$str1 = $weburl.'-'.$num;				//如果存在则把指针返回到该行前，覆盖写入内容，实现修改				fseek($cf,-$len,SEEK_CUR);				fwrite($cf,$str1);				fseek($cf,$len,SEEK_CUR);				fclose($cf);				return $num;								}		}		//未找到则在末尾换行增加一行记录		fwrite($cf, "\r\n".$weburl.'-1');		return 1;	}}?><html>	<head>		<title>访客计数器</title>	</head>	<body>		<center>			<h1>欢迎访问</h1><br />			<form action="" name="url-form" method="get">				<div>					<input type="text" name="weburl" size="15" />					 					<input type="submit" name="Submit" value="提交" />				</div>			</form>			<hr />			<font size="7" color="red">				您是第<?php echo counter(); ?>位访客			</font>		</center>	</body></html>
