PHP function that converts a glob pattern into a regular expression, extracted from the Symfony Finder component.

Installation

To install via Composer, do the following:

$ composer req ashleydawson/globtoregex

Requirements are:

• PHP >= 7.1

Basic Usage

Basic usage of the function is as follows:

<?php

require __DIR__.'/vendor/autoload.php';

$regex = \AshleyDawson\GlobToRegex\glob_to_regex('/**/*.txt');

echo $regex;

Where output is:

#^(?=[^\.])/(?:(?=[^\.])[^/]++/)*(?=[^\.])[^/]*\.txt$#

Usage

The following simple example returns a set of matched file paths:

<?php

require __DIR__.'/vendor/autoload.php';

use function AshleyDawson\GlobToRegex\glob_to_regex;

$paths = [
    '/foo/bar/sample.txt', 
    '/baz/biz/example.txt', 
    '/fiz/boo/music.mp3',
];

// Find matches for the glob pattern `/**/*.txt`
$regex = glob_to_regex('/**/*.txt');

$matches = array_filter($paths, function ($path) use ($regex) {
    return preg_match($regex, $path);
});

print_r($matches);

Where output is:

Array
(
    [0] => /foo/bar/sample.txt
    [1] => /baz/biz/example.txt
)
