Hello :), heres my script and i don't understand what's wrong with it -

<html>
<body>
<?php
$file="file.txt";
$fileo = fopen($file,"a");
$filew = fwrite($fileo,"Rocks Are Cool");
$filer = fread($fileo);
$filec = fclose($file);
echo $filer;
?>
</body>
</html>

Replace fread (which returns a handle) with file_get_contents.

I Mean, use this...

<html>
<body>
<?php
$file="file.txt";
$fileo = fopen($file,"a");
fwrite($fileo,"Rocks Are Cool");
fclose($file);
$filer = file_get_contents($file);
echo $filer;
?>
</body>
</html>

Also, you're trying to fclose() a string. Should be:

<html>
<body>
<?php
$file="file.txt";
$fileo = fopen($file,"a");
fwrite($fileo,"Rocks Are Cool");
fclose($fileo);
$filer = file_get_contents($file);
echo $filer;
?>
</body>
</html>

$fileo = fopen($file,"a");
$fileo is a file handle.
"file.txt" is a string.

you can only close handles, not strings.
which i the script tried to do here
fclose($file);
