* PHP support for the Libravatar.org service.
|
||||
*
|
||||
* Using this class is easy. After including or requiring
|
||||
* PEAR/libravatar.php simply do:
|
||||
* <code>
|
||||
* $libravatar = new Services_Libravatar();
|
||||
* $url = $libravatar->url('melissa@meldraweb.com');
|
||||
* </code>
|
||||
* Services/Libravatar.php simply do:
|
||||
* <code>
|
||||
* $libravatar = new Services_Libravatar();
|
||||
* $url = $libravatar->getUrl('melissa@meldraweb.com');
|
||||
* </code>
|
||||
*
|
||||
* This would populate $url with the string:
|
||||
* http://cdn.libravatar.org/avatar/4db84629c121f2d443d33bdb9fd149bc
|
||||
* This would populate $url with the string:
|
||||
* <code>
|
||||
* http://cdn.libravatar.org/avatar/4db84629c121f2d443d33bdb9fd149bc
|
||||
* </code>
|
||||
*
|
||||
* A complicated lookup using all the options is:
|
||||
* <code>
|
||||
* $libravatar = new Services_Libravatar();
|
||||
* $options = array();
|
||||
* $options['s'] = '40';
|
||||
* $options['algorithm'] = 'sha256';
|
||||
* $options['https'] = true;
|
||||
* $options['d'] = 'http://upload.wikimedia.org/wikipedia/commons/a/af/Tux.png';
|
||||
* $url = $libravatar->url('melissa@meldraweb.com', $options);
|
||||
* </code>
|
||||
* <code>
|
||||
* $libravatar = new Services_Libravatar();
|
||||
* $libravatar->setSize(40);
|
||||
* $libravatar->setAlgorithm('sha256');
|
||||
* $libravatar->setHttps(true);
|
||||
* $libravatar->setDefault(
