Le souci c'est qu'une fois m'être identifié et avoir posté mon commentaire, j'ai ce message d'erreur :

Code:

Fatal error: Call to a member function getVideoEntry() on a non-object in /htdocs/public/www/tests.php on line 55

et si je reviens à la page précédente, je trouce ceci:

You are authenticated!

Code:

Fatal error: Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Argument is not an instance of Zend_Http_Client.' in /htdocs/public/www/Zend/Gdata/YouTube.php:231 Stack trace: #0 /htdocs/public/www/Zend/Gdata/YouTube.php(212): Zend_Gdata_YouTube->setHttpClient(Object(__PHP_Incomplete_Class), '675765237623', '987348763498537...', 'AI39si7KdFT8_t4...') #1 /htdocs/public/www/tests.php(116): Zend_Gdata_YouTube->__construct(Object(__PHP_Incomplete_Class), '675765237623', '987348763498537...', 'AI39si7KdFT8_t4...') #2 {main} thrown in /htdocs/public/www/Zend/Gdata/YouTube.php on line 231

je précise que j'ai emprunté ce code ici: http://stackoverflow.com/questions/8...-youtube-gdata

Si quelqu'un peut m'aider ?

Merci.
