Summary
-------

[](#summary)

Regex enables to work with a validated [regular expression](https://en.wikipedia.org/wiki/Regular_expression).

Installing
----------

[](#installing)

Regex is available through [Packagist](https://packagist.org/packages/chevere/regex) and the repository source is at [chevere/regex](https://github.com/chevere/regex).

```
composer require chevere/regex
```

Creating Regex
--------------

[](#creating-regex)

Create a Regex by passing the regular expression pattern.

```
use Chevere\Regex\Regex;

$regex = new Regex('/^Hello World!$/');
```

Reading pattern
---------------

[](#reading-pattern)

### As-is

[](#as-is)

The `__toString` method is used to access the pattern passed on instance creation.

```
$string = $regex->__toString();
// /^Hello World!$/
```

### Without delimiters

[](#without-delimiters)

The `noDelimiters` method is used to access to the regex pattern without delimiters.

```
$string = $regex->noDelimiters();
// ^Hello World!$
```

### Without delimiters and anchors

[](#without-delimiters-and-anchors)

The `noDelimitersNoAnchors` method is used to access to the regex pattern without delimiters and anchors.

```
$string = $regex->noDelimitersNoAnchors();
// Hello World!
```

Match
-----

[](#match)

The `match` method provides [preg\_match](https://www.php.net/preg-match).

```
$array = $regex->match('Hello World!');
// [Hello World!]
```

Match All
---------

[](#match-all)

The `matchAll` method provides [preg\_match\_all](https://www.php.net/preg-match-all).

```
$regex->matchAll();
// [Hello World!]
```

Assert Match
------------

[](#assert-match)

The `assertMatch` method asserts that the string matches. It throws `Exceptions\NoMatchException` when failing to assert.

```
$regex->assertMatch('Hello World!');
```

Assert Match All
----------------

[](#assert-match-all)

The `assertMatchAll` method asserts that the string matches all. It throws `Exceptions\NoMatchException` when failing to assert.

```
$regex->assertMatchAll('Hello World!');
```
