Find pathnames matching a pattern

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

pattern

The pattern. No tilde expansion or parameter substitution is done. Special characters:

*	Matches zero or more characters.
?	Matches exactly one character (any character).
[...]	Matches one character from a group of characters. If the first character is !, matches any character not in the group.
\	Escapes the following character, except when the GLOB_NOESCAPE flag is used.

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GLOB_NOESCAPE	Backslashes do not quote metacharacters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.

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Note: On some systems it is impossible to distinguish between empty match and an error.
