str_replace - Modify external file?

Hello,

My data.txt file is formated like this:

qqqq||eeee
rrrr||tttt
yyyy||uuuu
iiii||oooo
aaaa||bbbb

I'm trying to get this code to replace the data I put in $name but it
is not changing.

How can the php code be changed to modify the data I put in $name?

<?php
$name = "aaaa"
if(is_writable("data.txt"))
{
$fp = fopen("data.txt","a");
$content = $fp;
$rplName = str_replace("aaaa","TestRpl",$content);
fwrite($fp, $rplName);
fclose($fp);
}
else
{
echo'File is not writable';
}
?>

Thank you for your help,

$filename = "data.txt";

$handle = fopen($filename,'r');
$content = fread($handle,filesize($filename));
echo $content;
$name = str_replace("aaa","TestRpl",$content);
fclose($handle);
if ($name)
{
$handle = fopen($filename,'w');
fwrite($handle,$name);
fclose($handle);

Hello Robin,

Thank you for the link below! I've been searching Google now for about
3 weeks for a solution and did not find one.
