Beispiele
Example#1
Convenient way how glob() can replace
opendir() and friends.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
Das oben gezeigte Beispiel erzeugt
eine ähnliche Ausgabe wie:
funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820
Anmerkungen

entfernten Dateien arbeiten, da
der Zugriff auf die Datei, die bearbeitet werden soll, über das Dateisystem des
Servers möglich sein muss.
Hinweis:
