glob() - a useful but obscure PHP function
Did you know this function exists? Well, since 4.3, there's this new PHP function called glob();
useful if one simply needs a list of files from a directory, and
eventually apply ereg patterns to file matching. Before one had to
either use the dir() class, or the opendir() function; something like this:
Now it's quite simple:
<?php $d = dir("/dir/"); echo "Handle: " . $d->handle . "n"; echo "Path: " . $d->path . "n"; while (false !== ($entry = $d->read())) { if (substr($entry, -3) == 'txt') { echo $entry .' size '. filesize($entry) ."n"; }} $d->close(); ?> Now it's quite simple:
<?php foreach (glob("/dir/*.txt") as $filename) { echo "$filename size " . filesize($filename) . "n"; } ?>
