Metóda - glob

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

The glob() function searches all files and directories matching a pattern by rules of the glob() function of the libc library. The rules are similar to rules in common shells.

Please note: The function works only in the filesystem of the given server and therefore there's no way to search for files of remote sources.

Please note: The function is not available on some systems, such as old Sun OS.

Please note: Tthe GLOB_BRACE flag is not available on some non-GNU systems, such as Solaris.

Procedurálne

• function glob (string $pattern, int $flags = 0) : array

Parametre

Názov	Dátový typ	Predvolená hodnota	Popis
$pattern	string		The pattern for searching, on which no tilde expansion nor parameter substitution is applied.
$flags	int	0	Accepts flags: GLOB_MARK - To each returned directory a slash is added. GLOB_NOSORT - The returned files are not sorted and are in the order as found. If this flag is not used, the files and directories are sorted alphabetically. GLOB_NOCHECK - If no matching files or directories are found, the pattern is returned. GLOB_NOESCAPE - Backslashes don't escape special characters. GLOB_BRACE - Sequences like {a, b, c} will be expanded to match "a", "b" or "c". GLOB_ONLYDIR - Returns matching directories only. GLOB_ERR - Stops the searching on errors (e.g. caused by unreadable files or directories). Errors are ignored without this flag.
