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="">
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?
