README

A parser for the Accept-Language HTTP header following RFC 2616

Usage

use Syonix\Http\Header\AcceptLanguage\AcceptLanguage;

$parsed = AcceptLanguage::parse('da, en-gb;q=0.8, en;q=0.7'); // Returns Array ordered by quality (q)
$parsed = AcceptLanguage::match('de-CH, de-DE;q=0.9, de;q=0.8', ['de-DE', 'de']); // Returns 'de-DE'

Notes

• AcceptLanguage::match() throws a RuntimeException, if none of the accepted languages matches and * is not in the Accept-Languages string.
• If * is accepted and none of the other accepted languages match, the passed $default parameter is passed
• If $default is omitted, the first element of the $locale array is returned.
• Both parse and match are case insensitive.
• parse always returns the case of the input string
• match always returns the case of the provided locale array.
• As per the RFC, the quality value defaults to q=1.
