/**
 * Searches and matches file paths using Ant-like globs.
 *
 * This class implements an Ant-like version of PHP's `glob()` function. The
 * wildcard "*" matches any number of characters except directory separators.
 * The double wildcard "**" matches any number of characters, including
 * directory separators.
 *
 * Use {@link glob()} to glob the filesystem for paths:
 *
 * ```php
 * foreach (Glob::glob('/project/**.twig') as $path) {
 *     // do something...
 * }
 * ```
 *
 * Use {@link match()} to match a file path against a glob:
 *
 * ```php
 * if (Glob::match('/project/views/index.html.twig', '/project/**.twig')) {
 *     // path matches
 * }
 * ```
 *
 * You can also filter an array of paths for all paths that match your glob with
 * {@link filter()}:
 *
 * ```php
 * $filteredPaths = Glob::filter($paths, '/project/**.twig');
 * ```
 *
 * Internally, the methods described above convert the glob into a regular
 * expression that is then matched against the matched paths. If you need to
 * match many paths against the same glob, you should convert the glob manually
 * and use {@link preg_match()} to test the paths:
 *
 * ```php
 * $staticPrefix = Glob::getStaticPrefix('/project/**.twig');
 * $regEx = Glob::toRegEx('/project/**.twig');
 *
 * if (0 !== strpos($path, $staticPrefix)) {
 *     // no match
 * }
 *
 * if (!preg_match($regEx, $path)) {
 *     // no match
 * }
 * ```
 *
 * The method {@link getStaticPrefix()} returns the part of the glob up to the
 * first wildcard "*". You should always test whether a path has this prefix
 * before calling the much more expensive {@link preg_match()}.

19			* Searches and matches file paths using Ant-like globs.
20			*
21			* This class implements an Ant-like version of PHP's `glob()` function. The
22			* wildcard "*" matches any number of characters except directory separators.
23			* The double wildcard "**" matches any number of characters, including
24			* directory separators.
25			*
26			* Use {@link glob()} to glob the filesystem for paths:
27			*
28			* ```php
29			* foreach (Glob::glob('/project/**.twig') as $path) {
30			* // do something...
31			* }
32			* ```
33			*
34			* Use {@link match()} to match a file path against a glob:
35			*
36			* ```php
37			* if (Glob::match('/project/views/index.html.twig', '/project/**.twig')) {
38			* // path matches
39			* }
40			* ```
41			*
42			* You can also filter an array of paths for all paths that match your glob with
43			* {@link filter()}:
44			*
45			* ```php
46			* $filteredPaths = Glob::filter($paths, '/project/**.twig');
47			* ```
48			*
49			* Internally, the methods described above convert the glob into a regular
50			* expression that is then matched against the matched paths. If you need to
51			* match many paths against the same glob, you should convert the glob manually
52			* and use {@link preg_match()} to test the paths:
53			*
54			* ```php
55			* $staticPrefix = Glob::getStaticPrefix('/project/**.twig');
56			* $regEx = Glob::toRegEx('/project/**.twig');
57			*
58			* if (0 !== strpos($path, $staticPrefix)) {
59			* // no match
60			* }
61			*
62			* if (!preg_match($regEx, $path)) {
63			* // no match
64			* }
65			* ```
66			*
67			* The method {@link getStaticPrefix()} returns the part of the glob up to the
68			* first wildcard "*". You should always test whether a path has this prefix
69			* before calling the much more expensive {@link preg_match()}.
70			*

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
