Gravatar URL builder (aka. a Gravatar library)

Install

Via Composer

$ composer require gravatarphp/gravatar

Usage

Create a Gravatar instance and use it for creating URLs.

use Gravatar\Gravatar;

// Defaults: no default parameter, use HTTPS
$gravatar = new Gravatar([], true);

// Returns https://secure.gravatar.com/avatar/EMAIL_HASH
$gravatar->avatar('user@domain.com');

// Returns https://secure.gravatar.com/avatar/EMAIL_HASH
// The fourth parameter enables validation and will prevent the
// size parameter from being added to the URL generated.
$gravatar->avatar('user@domain.com', ['s' => 9001], true, true);

// Returns https://secure.gravatar.com/EMAIL_HASH
$gravatar->profile('user@domain.com');

// Returns https://secure.gravatar.com/EMAIL_HASH.vcf
$gravatar->vcard('user@domain.com');

// Returns https://secure.gravatar.com/EMAIL_HASH.qr
$gravatar->qrCode('user@domain.com');

You can override the globally used protocol (HTTP, HTTPS) by setting the last parameter to true/false.

use Gravatar\Gravatar;

$gravatar = new Gravatar();

// Returns http://www.gravatar.com/avatar/EMAIL_HASH
$gravatar->avatar('user@domain.com', [], false);

// Returns http://www.gravatar.com/EMAIL_HASH
$gravatar->profile('user@domain.com', false);

// Returns http://www.gravatar.com/EMAIL_HASH.vcf
$gravatar->vcard('user@domain.com', false);

// Returns http://www.gravatar.com/EMAIL_HASH.qr
$gravatar->qrCode('user@domain.com', false);

Last, but not least, you can pass default options to the builder and use them to generate avatar URLs.

use Gravatar\Gravatar;

$gravatar = new Gravatar([
    'size' => 500,
]);

// Returns https://secure.gravatar.com/avatar/EMAIL_HASH?size=500&r=g
$gravatar->avatar('user@domain.com', ['r' => 'g']);

Parameters

If you pass any of the following parameters and turn validation on (fourth parameter in the avatar() method), their values will be checked against the allowed values defined in the Gravatar documentation:

• s, size -- The image size
• d, default -- The default image to display if there is no matching Gravatar
• f, forcedefault -- Tell Gravatar to use the default image even if there is a matching Gravatar
• r, rating -- The audience rating (G, R, etc.) to restrict the Gravatar to

If the value fails validation, an InvalidArgumentException will be thrown. Any parameters not listed above are not sanitized or validated in anyway.

Notes

Profile, vCard and QR Code requests will only work with the primary email address. This is a limitation of Gravatar. However the builder won't complain, since it doesn't know if it is your primary address or not. For more tips and details check the Gravatar documentation.

Testing
