本文实例讲述了php使用文本统计访问量的方法。分享给大家供大家参考，具体如下：
方法1：
$fp = fopen("counter.txt", "r+");while(!flock($fp, LOCK_EX)) { // acquire an exclusive lock // waiting to lock the file}$counter = intval(fread($fp, filesize("counter.txt")));$counter++;ftruncate($fp, 0); // truncate filefwrite($fp, $counter); // set your datafflush($fp); // flush output before releasing the lockflock($fp, LOCK_UN); // release the lockfclose($fp); 方法2：
counter.php文件：
<?php/* counter *///opens countlog.txt to read the number of hits$datei = fopen("countlog.txt","r");$count = fgets($datei,1000);fclose($datei);$count=$count + 1 ;echo "$count" ;echo " hits" ;echo "/n" ;// opens countlog.txt to change new hit number$datei = fopen("countlog.txt","w");fwrite($datei, $count);fclose($datei);?> 用法：
<?phpinclude("counter.php");?>
