Bonjour,

Je me suis retrouvé dans la situation où mon hébergeur a fait la mise à jour php5.5 et donc mon fichier en mysql n'est plus opérationnel.
J'ai effectué la migration à l'aide de mysql convert tool et 2 lignes de code apparaissent avec des problèmes.

Malgré mes recherches sur la toile et plusieurs essais infructueux depuis quelques jours, je m'en remets à vous demander de l'aide SVP.

Je vous livre les deux lignes avant et après modifications, avec les messages d'erreur.

Voici l'extrait avant avec pour message d'erreur : mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead

//! Connect to the MySQL server
public function connect() {
$this->link = @mysql_connect($this->host,$this->user,$this->password);
if (!$this->link)
throw new Exception("Cannot connect to the database.");
$this->selectDB($this->dbname);
$this->connected = true;
}

public function selectDB ($dbname) {
if (!@mysql_select_db($dbname,$this->link))
throw new Exception("This database ($dbname) doesn't exist.");
}

public function getVersion () {
if (!$this->connected)
$this->connect();
return mysql_get_server_info($this->link);



Voici l'extrait après modifications avec pour message d'erreur : Line Message
44 [Line 44] Cannot analyze server parameter to extract host, socket and port! Conversion cannot be performed automatically. You must manually check the result of the conversion.
52 [Line 52] mysql_select_db(string database_name [...]) is emulated using mysqli_query() and USE database_name. This is a possible SQL injection security bug as no tests are performed what value database_name has. Check your script!
Generated Code

//! Connect to the MySQL server
public function connect() {
$this->link = @($GLOBALS["___mysqli_ston"] = mysqli_connect($this->host, $this->user, $this->password));
if (!$this->link)
throw new Exception("Cannot connect to the database.");
$this->selectDB($this->dbname);
$this->connected = true;
}

public function selectDB ($dbname) {
if (!@((bool)mysqli_query($this->link, "USE " . $dbname)))
throw new Exception("This database ($dbname) doesn't exist.");
}

public function getVersion () {
if (!$this->connected)
$this->connect();
return ((is_null($___mysqli_res = mysqli_get_server_info($this->link))) ? false : $___mysqli_res);
}

Voilà pour les "problèmes".

Merci d'avance pour votre éventuelle réponse.

Cordialement

Bonjour,

La première action est déjà de supprimer les "@" dans ton code car le but des "@" est de masquer les erreurs PHP, ce qui peut être assez problématique pour déboguer son code.

Ensuite au niveau de ton code :

$this->link = @($GLOBALS["___mysqli_ston"] = mysqli_connect($this->host, $this->user, $this->password));

Là je comprends pas ce que tu essaye de faire...

Ensuite pour ta seconde erreur, mysqli à une fonction dédiée mysqli_select_db() pour sélectionner la base de données, plutôt que de faire une query("USE nom_de_la_bdd");
http://php.net/mysqli_select_db

Merci pour ta réponse,

Le script était déjà écrit et je l'ai juste converti tel quel. J'ai juste livré la ligne car je ne comprenais pas la structure également

Je vais donc supprimer les @, et voir comment ça réagit.

Pour la deuxième ligne faut-il la réécrire ?

Je ne comprends pas forcément comment modifier ces lignes à l'aide du lien, j'ai fait quelques tentatives mais en vain.

Voici le fichier complet, si ça peut aider
