Description: ------------ When readLine() comes to an empty line in a text file, it stops. Reproduce code: --------------- while ($line = File::readLine('file')) { print $line; } compare with: $fp = fopen('file', 'r'); while ($line = fgets($fp, 1024)) { print $line; } fclose($fp); Expected result: ---------------- The while loop should continue until all lines in 'file' have been read and returned. Actual result: -------------- The while loop stops at the first empty line in 'file'

Your code is at fault, not the package.

In what way is my code at fault? The File documentation does not indicate any methods to either determine the number of lines in a file, nor to determine if there are lines left to be read.

Because while treats 0, null, '' and so on as false. You should use while(false !== $line = File::readLine()) HTH
