Hello

Unless I'm missing something, I think the problem is that you are not
capturing the output of str_replace(). It does not modify the string
in-place; it returns the modified version of the string. So, instead
of:

str_replace('</rss>', '', $xmlFileContents);
str_replace('</channel>', '', $xmlFileContents);

do:

$xmlFileContents = str_replace('</rss>', '', $xmlFileContents);
$xmlFileContents = str_replace('</channel>', '', $xmlFileContents);
