I'm trying to build a tiny skeleton framework for a friend, where each time a button is pressed a certain animation is played. He wants a way to count the number of times the button is clicked, as well, but I can't seem to get that part working. What am I doing wrong?

<?php

  if( isset($_POST['mushu']) )
  {
    echo "Working.";
    playAnimation();
    clickInc();
  }

  function playAnimation()
  {
     /* ... */;
  }

  function clickInc()
  {
    $count = ("clickcount.txt");

    $clicks = file($count);
    $clicks[0]++;

    $fp = fopen($count, "w") or die("Can't open file");
    fputs($fp, "$clicks[0]");
    fclose($fp);

    ech开发者_运维知识库o $clicks[0];

  }
?>

<html>

  <head>

    <title>Adobe Kitten</title>

  </head>

  <body>

    <form action="<?php $_SERVER['PHP_SELF']; ?>">
    <input type="button"
           value="Let's see what Mushu is up to."
           name="mushu">
    </form>

  </body>
</html>

<form action="<?php $_SERVER['PHP_SELF']; ?>" method="post">
    <input type="submit"
           value="Let's see what Mushu is up to."
           name="mushu">
</form>

First of all use the form with method="post", or change $_POST[] to $_GET[] in your Script.

And If your Button is not a Submit button, then you are not submitting the form. So I've changed type="button" to type="submit".

Should work

The code looks fine, I tested it and it worked for me. I suggest:

Make sure the file isn't read-only.
Make sure the file is called "clickcount.txt"
Make sure it's in the same folder as your script.

It would be helpful to know the error but a shot in the dark - it could be a problem with Write permissions?

also, change to:

<input type="submit" value="Let's see what Mushu is up to." name="mushu" />
