我想在我的网页上集成一个计数器，到目前为止我已经这样做了，所以计数器可以工作。但我真正想要的是这个计数器特定于每个要生成的每个页面id

<?php

session_start();

$counter_name = 'counter'.$id.'.txt';
// Check if a text file exists. If not create one and initialize it to zero.
if (!file_exists($counter_name)) {
  $f = fopen($counter_name, "w");
  fwrite($f,"0");
  fclose($f);
}
// Read the current value of our counter file
$f = fopen($counter_name,"r");
$counterVal = fread($f, filesize($counter_name));
fclose($f);
// Has visitor been counted in this session?
// If not, increase counter value by one
if(!isset($_SESSION['hasVisited'])){
  $_SESSION['hasVisited']="no";
  $counterVal++;
  $f = fopen($counter_name, "w");
  fwrite($f, $counterVal);
  fclose($f); 
}
else {
    $counterVal++;
    $f = fopen($counter_name, "w");
    fwrite($f, $counterVal);
    fclose($f);
}
$counterVal = str_pad($counterVal, 5, "0", STR_PAD_LEFT);
$chars = preg_split('//', $counterVal);
$im = imagecreatefrompng("canvas.png");
$src1 = imagecreatefrompng("$chars[1].png");
$src2 = imagecreatefrompng("$chars[2].png");
$src3 = imagecreatefrompng("$chars[3].png");
$src4 = imagecreatefrompng("$chars[4].png");
$src5 = imagecreatefrompng("$chars[5].png");
imagecopymerge($im, $src1, 0, 0, 0, 0, 15, 15, 100);
imagecopymerge($im, $src2, 15, 0, 0, 0, 15, 15, 100);
imagecopymerge($im, $src3, 30, 0, 0, 0, 15, 15, 100);
imagecopymerge($im, $src4, 45, 0, 0, 0, 15, 15, 100);
imagecopymerge($im, $src5, 60, 0, 0, 0, 15, 15, 100);
// Output and free from memory
header('Content-Type: image/png');
echo imagepng($im);
imagedestroy($im);
?>

使用此代码，我只能看到主页的点击量。它以相同的数字显示在每一页上。

page 1 count: 100 
page 2 count: 100

在我刷新 50 倍第 1 页后

page 1 count: 150
page 2 count: 150

文件名counter.php在模板文件上实现，代码如下

 <img style="padding-left: 2px;" alt="Hit counter" src="http://www.example.com/counter/counter.php" />

我一直在寻找解决方案，但到目前为止还没有找到任何解决方案。
提前致谢。

最好的问候，
布哈拉。

对于$id您正在使用的未定义变量，您可以使用例如来自服务器的路径信息：

<?php

session_start();

$id = preg_replace('[^\w-]', '', $_SERVER['PATH_INFO']);

$counter_name = 'counter' . $id . '.txt';

// etc.

请注意，我已删除所有特殊字符以避免出现问题。
