Piping the output of "ls" and parsing that if you don't have glob() handy is kind of
a bad hack. Here's a far better implementation that uses normal PHP functions that you will
find in < 4.3.0.
if ($fp = opendir('.')) {
while (($file = readdir($fp)) !== FALSE) {
if (is_file($file) && preg_match('/\.txt$/', $file)) {
echo "$file\n";
}
}
closedir($fp);
}
It's set to return only files, not directories, but you can change that easily by removing the
is_file() check. Also, this gives you the extra power of a full regex pattern matcher which glob()
may not be able to provide.
