Finding Files Matching a Pattern

$log_files = File::glob('/test/*.log');
if ($log_files === false)
{
    die("An error occurred.");
}

You can also pass flags to the method.

$dir_list = File::glob('/test/*', GLOB_ONLYDIR);
if ($dir_files === false)
{
    die("An error occurred.");
}

Valid flags are:

• GLOB_MARK - Adds a slash to each directory returned
• GLOB_NOSORT - Return files as they appear in the directory (no sorting)
• GLOB_NOCHECK - Return the search pattern if no files matching it were found
• GLOB_NOESCAPE - Backslashes do not quote meta-characters
• 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 empty array if no files are matched or a false on error.

Note that on some systems there's no difference between an empty match and an error.
