guzzle-transcoder

Packagist Version

This package provides a Guzzle 6/7 middleware that transparently converts documents obtained by Guzzle from its native encoding to UTF-8 (or any other specified encoding). It supports the following features:

  • Detection of charset from Content-Type HTTP header.
  • Detection of charset from meta element in HTML document.
  • Detection of charset from XML declaration in RSS and other XML documents.
  • Updating the Content-Type header in the Response object according to target encoding.
  • Updating the metadata in the Response body according to target encoding (not enabled by default).

Installation

It is recommended to install the library using Composer:

composer require fossar/guzzle-transcoder

Usage

Basic example

use Fossar\GuzzleTranscoder\GuzzleTranscoder;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;

$stack = HandlerStack::create();
$stack->push(new GuzzleTranscoder);
$client = new Client(['handler' => $stack]);

$url = 'https://www.myseosolution.de/scripts/encoding-test.php?enc=iso'; // request website with iso-8859-1 encoding
$req = $client->get($url);
echo $req->getBody();

Full example

use Fossar\GuzzleTranscoder\GuzzleTranscoder;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;

$stack = HandlerStack::create();
$stack->push(new GuzzleTranscoder([
	'targetEncoding' => 'windows-1252',
	// Swap the default settings:
	'replaceHeaders' => false,
	'replaceContent' => true,
]));
$client = new Client(['handler' => $stack]);

$url = 'https://www.myseosolution.de/scripts/encoding-test.php?enc=iso'; // request website with iso-8859-1 encoding
$req = $client->get($url);
echo $req->getHeaderLine('Content-Type') . "\n"; // HTTP header will remain unchanged
echo $req->getBody();

Credits

It is largely based on Pascal Landau’s guzzle-auto-charset-encoding-subscriber and web-utility libraries.

We are using Transcoder library. This allows us to fall back to iconv when mbstring is not available or an encoding is not supported by it.
