本文實例講述了php使用文字統計訪問量的方法。分享給大家參考，具體如下：
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檔：
<?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");
?>
