glob

(PHP 4 >= 4.3.0, PHP 5)

globFind pathnames matching a pattern

Descrizione

array glob ( string $pattern [, int $flags = 0 ] )

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.

flags

Valid flags:

  • GLOB_MARK - Adds a slash to each directory returned
  • GLOB_NOSORT - Return files as they appear in the directory (no sorting). When this flag is not used, the pathnames are sorted alphabetically
  • GLOB_NOCHECK - Return the search pattern if no files matching it were found
  • GLOB_NOESCAPE - Backslashes do not quote metacharacters
  • GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', or 'c'
  • GLOB_ONLYDIR - Return only directory entries which match the pattern
  • GLOB_ERR - Stop on read errors (like unreadable directories), by default errors are ignored.

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 visualizzerĂ  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.
