glob

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

globFind pathnames matching a pattern

Descrizione

glob(string $pattern, int $flags = 0): array|false

The glob() function searches for all the pathnames matching pattern according to the rules used by the libc glob() function, which is similar to the rules used by common shells.

Elenco dei parametri

pattern

The pattern. No tilde expansion or parameter substitution is done.

Special characters:

  • * - Matches zero or more characters.
  • ? - Matches exactly one character (any character).
  • [...] - Matches one character from a group of characters. If the first character is !, matches any character not in the group.
  • \ - Escapes the following character, except when the GLOB_NOESCAPE flag is used.

flags

Any of the GLOB_* constants.

Valori restituiti

Returns an array containing the matched files/directories, an empty array if no file matched or false on error.

Nota:

On some systems it is impossible to distinguish between empty match and an error.

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).

  • readdir() - Legge una voce dall'handle della directory
  • closedir() - Chiude l'handle della directory
  • fnmatch() - Match filename against a pattern

Include dotfiles excluding . and .. special dirs with .[!.]*

<?php
$all_files
= array_merge(glob('.[!.]*'), glob('*'));
// or
$all_files = glob('{.[!.],}*', GLOB_BRACE);
?>
