  • 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  • GLOB_NOESCAPE - Backslashes do not quote metacharacters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

4.3.3 GLOB_ONLYDIR became available on Windows and other systems not using the GNU C library

Példák

Example#1 Convenient way how glob() can replace opendir() and friends.

<?php
foreach (glob("*.txt") as $filename) {
    echo 
"$filename size " filesize($filename) . "\n";
}
?>

A fenti példa valami ilyesmi kimenetet ad:

funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820

Note: Ez a függvény nem fog távoli fájlokkal működni, az a szerver helyi fájlrendszerén lesz keresve.

Note: This function isn't available on some systems (e.g. old Sun OS).

Note: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.
