In your output file, the error on fopen is showing a newline after the
file name. When you use fgets() to get the filenames, it includes the
newline from the file.
This will get rid of the newline character. The trim function removes
any whitespace around a string.
$mainfileline = trim(fgets($mainfile, 1024));
