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 file

fwrite($fp, $counter); // set your data

fflush($fp);      // flush output before releasing the lock

flock($fp, LOCK_UN);  // release the lock

fclose($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：

<?php

include("counter.php");

?>

希望本文所述对大家PHP程序设计有所帮助。
