PHP代码不起作用[关闭]

i'm trying to create a counter of my website visit and i did something like this:

contatore.txt: 0

index.html:

<html><head>
</head>
<body>
<p><?php include ("counter.php"); ?></p>
</body></html>

counter.php:

<?php
    $file_handle = fopen("contatore.txt", "r");
    $line = ((int)(fgets($file_handle))) + 1;
    fclose($file_handle);
    $fh = fopen( 'filelist.txt', 'w' );
    fwrite($fh, (string)($line));
    fclose($fh);
    echo ((string)($line));
?>

here is the problem: the browser just auto hide the php code usin :( can you help me?? thanks

Your file is named index.html. Unless you told your server that .html files should be treated as PHP scripts, that means the PHP code is NOT being executed - it's going out as literal text. And since PHP tags make it look like HTML, your browser is properly hiding that unknown/illegal tag.

Rename it to index.php.
