glob
Find pathnames matching a pattern
Syntax
glob ( string $pattern [, int $flags = 0 ] ) : array
Parameters
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| GLOB_NOESCAPE | Backslashes do not quote metacharacters |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. |
Return
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.
