You could use file_get_contents to read the entire file into a string,
then perform a str_replace to replace the unwanted part of the string
with "". Then write the content back into the file.
$filename = "path/to/file";
$unwanted = "some unwanted string";
$content = file_get_contents($filename);
$clean_content = str_replace($unwanted, "", $content);
file_put_contents($filename, $clean_content);
