You have to write the whole file over. So read the entire file into a
string. If you know you're looking to match $template, then you can use
a preg_replace() call.
$new_value = "red";
preg_replace('/\$template="[^"]";/','$template="'.$new_value.'";',$text)
;
or something similar. Adapt to your needs.
