I am making a script and i came upon a need to overwrite a file rather than just add to it. I am using $file = @fopen($filename, "w"); but that just adds. Does anyone know the code to overwrite? Thanks for the help

I actually tried that before and it didn't work. I also just tried it again and still no good :( . By what it says on that page, a simple "w" should work too, but it doesn't. Anyone know whats wrong?

Your right, "w" should be enough. But "that page" is the PHP manual, and I'm pretty sure it is right sooooo. Make sure

Safe mode is not enabled(or that the PHP user is the owner of the file)
$filename is NOT a URL eg. http://www.blah.com
fopen() is not failing. Remove the "@' in front of fopen to find out

Ok, i made sure of the second 2 things you said and they check out, but I have cpanel and I am not sure how to check safe mode. Do I just talk to my host? thanks

You could make a php page with


<?

phpinfo();

?>

and it will say if Safe Mode is enabled. If so, being that you use CPanel, I doubt that your webhost will disable it, but every webhost is different.

Always a good way to find things out, but phpinfo() will tell you. If you could post your complete code I might be able to find the problem

Ok, i ran the phpinfo() script and didn't see anything saying safe mode was enabled. Here is the php info http://echodesign.jexhost.com/testing/test.php

Do you mean you need some of the script code?No. He means he needs all of it.
Also, could the file to write to being a .txt be a problem?No.

Ok, here is the full code:

<?php
$filename = "sitename.txt"; // file to write to

$error = "An error occured while changing the site name!";

$success = "Site name changed, redirecting...";



// Change Name
$name = stripslashes($_POST['name']);

// Change URL
if ($sitelink = stripslashes($_POST['sitelink'])) {

$add = "
<!-- Site Name -->
<a href=".$sitelink.">".$name."</a>
";

$sitename = @file_get_contents($filename).$add;


$file = @fopen($filename, "w+");
@fwrite($file, $sitename);
@fclose($file);
$message = $success;
}
else {
$message = $error;
}
echo "
<html>
<head>
<title>Change Site Name</title>
<meta http-equiv=\"refresh\" content=\"2;url=changetitles.php\">
".$message."
</head>
<body>
</body>
</html>";

?>

$sitename = @file_get_contents($filename).$add;

This line is causing it to append the contents instead of overwriting it. If you want the file overwritten replace the above code with this.


$sitename = $add;

If you want it to append remove


$sitename = @file_get_contents($filename).$add;

and replace

$file = fopen($filename, "w");
with

$file = fopen($filename,'a');
