How to build a url of a GRAVATAR image from a given email

There is a simple way with php, a simple script or URL manipulation to build a URL for the gravatar image corresponding to an email?

Ex. http://gravatar.com/avatars/avatar.php?email=myemail@myserver.com and this return a jpeg or png image.

If there is no simple way like the example, what is the easiest way you know to resolve a url of the gravatar corresponding to an email?. Thanks

Use this:

$userMail = whatever_to_get_the_email;

$imageWidth = '150'; //The image size

$imgUrl = 'http://www.gravatar.com/avatar/'.md5($userMail).'?size='.$imageWidth;

(Fixed the $imgUrl)

You can use this code to get an email's avatar set on Gravatar.com or generate a default avatar if no avatar found for that email.

You just need to pass an email as a parameter and call this function anywhere in your project.

public function  get_avatar($email){

    $url = 'https://www.gravatar.com/avatar/'; // The gravatar's API url
    $url .= md5( strtolower( trim( $email ) ) ); // Hash the user's email
    $url .='.png?s=300'; // Get a custom image size

        //Extract the image if is set on Gravatar

    if ( isset($img) ) {
        foreach ( isset($atts) as $key => $val )
            $url .= ' ' . $key . '="' . $val . '"';
    }

    return $url; // Return the avatar's url or the default avatar if no image found.

}

You can just see this simple function of Gravatar which can:

  1. Check if the email has any gravatar or not.

  2. Return the gravatar image for that email.

    <?php

class GravatarHelper
{

  /**
  * validate_gravatar
  *
  * Check if the email has any gravatar image or not
  *
  * @param  string $email Email of the User
  * @return boolean true, if there is an image. false otherwise
  */
  public static function validate_gravatar($email) {
    $hash = md5($email);
    $uri = 'http://www.gravatar.com/avatar/' . $hash . '?d=404';
    $headers = @get_headers($uri);
    if (!preg_match("|200|", $headers[0])) {
      $has_valid_avatar = FALSE;
    } else {
      $has_valid_avatar = TRUE;
    }
    return $has_valid_avatar;
  }

  /**
  * gravatar_image
  *
  *  Get the Gravatar Image From An Email address
  *
  * @param  string $email User Email
  * @param  integer $size  size of image
  * @param  string $d     type of image if not gravatar image
  * @return string        gravatar image URL
  */
  public static function gravatar_image($email, $size=0, $d="") {
    $hash = md5($email);
    $image_url = 'http://www.gravatar.com/avatar/' . $hash. '?s='.$size.'&d='.$d;
    return $image_url;
  }

}

You can use then like:

if (GravatarHelper::validate_gravatar($email)) {
   echo GravatarHelper::gravatar_image($email, 200, "identicon");
}

Though @dipi-evil's solution works fine, I wasn't getting larger image with it. Here's how I got it working properly.

$userMail = 'johndoe@example';

$imageWidth = '600'; //The image size

$imgUrl = 'https://secure.gravatar.com/avatar/'.md5($userMail).'?size='.$imageWidth;

You can find a sample script with PHP code on their implementation site: http://en.gravatar.com/site/implement/php

The root script is at http://www.gravatar.com/avatar/ The next part of the URL is the hexadecimal MD5 hash of the requested user's lowercased email address with all whitespace trimmed. You may add the proper file extension, but it's optional.

The complete API is here http://en.gravatar.com/site/implement/
