J'ai trouvé un script de like, celui-ci est orienté objet, je souhaiterai avoir la même réciprocité sans objet

ci-joint, le script ! merci

<?php

}
}

$conn = mysql_connect($this->host,$this->user,$this->password);
return $conn;
}

function selectDB($conn) {
mysql_select_db($this->database,$conn);
}
