If you want to ensure that the file is not changed by other scripts while
you're reading from it, yes. Note that this is advisory only - writer
scripts will only respect the lock if they request a write lock. See
manual for details.

flock() takes a file handle as an argument, not an array of strings:
$fh = fopen("/path/file.ext", 'r');
flock($fh, LOCK_SH);
// read from file here
flock($fh, LOCK_UN);
fclose($fh);
See example 1 in the manual page for flock for more info.
