Keith,

Another interesting addition to all of this, both your code and my
developers original code work on our PHP v4 instance.

It might be a bug in PHP 5.2.5, as I had problems with that version. I downgraded to 5.2.4 - that's what I used to test my code on.

However the code you posted did not work for me on 5.2.4

Regards

Keith

Is this what you are looking for Jesse:

<html>

<head>
<title>Wiki Text Tester</title>
</head>

<body>

<?php

echo "Contents of \$_POST array: <br />";

while (list($key, $value) = each($_POST))
  {
  echo "$key: $value <br />";
  }

?>

<br />

<form method="post" action="" accept-charset="utf-8">

<textarea name="wikitext" cols="80" rows="10">
<?php echo $_POST['wikitext'] ?>
</textarea>

<input type="submit" />
</form>

</body>
</html>

The above also works with <html> or html in the text area.

I tried your code on my machine but it was doing strange
things to the URL for the page.

HTH

One of our developers has brought an interesting problem to my
attention.
I'll start off by describing our environment.  We are running a Solaris
10
server with Apache 2.2.6.  PHP version 5.2.5 is loaded as a module and
appears to be working fine.  However, our developer ran into a problem
using dokuwiki.  When he submits a form with a <html> tag in it, he
receives a 400 error.  He threw together this little script to verify
the
problem:

<html>
<body>
<?php
echo sprintf("%s", $_POST['wikitext']);
?>
<br />
<form method="post" action="<?=$_SERVER['PHP_SELF']?>"
accept-charset="utf-8">
<textarea name="wikitext" style="height: 300px;" cols="80"
rows="10"></textarea>

<input type="submit"/>
</form>
</body>
</html>

This can be viewed here:  http://eagles.its.csulb.edu/php/PostTest.php

As you can see, the script does nothing more than take what is submitted
and display it on the screen.  However, if you type in <html> then click
on the Submit Query button, you will get a 400 error.

Does anyone know why this is occurring?  Am I looking at some php.ini
parameter change to fix this?
