# glob

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

glob — Find pathnames matching a pattern

### Description

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

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.

### Parameters

`pattern`

  The pattern. No tilde expansion or parameter substitution is done.

`flags`

  Valid 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  - `GLOB_NOESCAPE` - Backslashes do not quote metacharacters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 Values

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.

### Changelog

Version | Description
--- | ---
5.1.0 | `GLOB_ERR` was added

### Examples

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

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

The above example will output something similar to:

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

### Notes

> Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

> 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.
