glob — Find pathnames matching a pattern
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.
The pattern. No tilde expansion or parameter substitution is done.
Valid flags:
Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on 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_BRACE flag is not available on some non GNU systems, like Solaris.
