(PHP 4 >= 4.3.0, PHP 5)
glob — Find pathnames matching a pattern
$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.
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)
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GLOB_NOESCAPE - Backslashes do not quote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.
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.
| Versione | Descrizione |
|---|---|
| 5.1.0 |
GLOB_ERR was added
|
| 4.3.3 |
GLOB_ONLYDIR became available on Windows and
other systems not using the GNU C library
|
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
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_BRACEflag is not available on some non GNU systems, like Solaris.
