Esempi
Example#1 Convenient way how glob() can replace opendir() and friends.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
Il precedente esempio visualizzerà qualcosa simile a:
funclist.txt size 44686 funcsummary.txt size 267625 quickref.txt size 137820
Note
Nota: Questa funzione non opererà su file remoti perché il file che deve essere esaminato deve essere accessibile attraverso il filesysmte del server.
Nota: This function isn't available on some systems (e.g. old Sun OS).
Nota: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.
