Glob( <pattern>, <flags> )

Description

Find files/folders matching a pattern.

Parameters

pattern

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

flags

Optional; Valid flags:

@GLOB_MARK - Adds a slash to each directory returned
@GLOB_NOSORT - Return files as they appear in the directory (no sorting, directories will be at top too)
@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@GLOB_NOESCAPE - Backslashes do not quote metacharacters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 Value

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

None

Example

To search in the directory for all files and directories that end with .txt, you would write:

$filelist = glob("*.txt");

If you want a list of files and directories that begin with “te”, the code to write is:

$filelist = glob("te*");

To get a list of directories only which contain “ma”, the code is:

$filelist = glob("*ma*", @GLOB_ONLYDIR);

Another example

$dir = './';
 
foreach(glob($dir.'*.txt') as $file) 
{
    print( $file . "\n");
}

Also possible:

$files = glob('*.*');

This shows how to use the @GLOB_BRACE flag:

$images = Glob('images/{*.jpg,*.gif,*.png}', @GLOB_BRACE);
printr($images);
