> See Reference : [RFC 7231](https://tools.ietf.org/html/rfc7231)

### Install

[](#get-best-match-between-need-and-offerings)

---

> **Note:** You can use `*` as wildcards for matching a family of choices.

```
$need  = 'image/*;q=0.9,*/*;q=0.2';
$offer = 'text/html,svg/xml,image/svg+xml';
echo Negotiation::bestMatch($need,$offer);
```

```
image/svg+xml

```

### Preferred and best match

[](#preferred-and-best-match)

---

Negotiation class automatically orders by priority based on `q` parameter.

```
$negotiatior = new Negotiation('en-US;q=0.3,it,en;q=0.4,es;q=0.9,de');
```

You can obtain the preferred response via the `preferred` method.

```
echo $negotiatior->preferred();
```

```
it

```

Or get the best match against another RFC7231 query

```
echo $negotiatior->best('es,en-US');
```

```
es

```

`false` will be returned if no match can be found.
