I am using web app and azure mySQL database. I tried using a simple connection and it works:

Code: Select all

$host = '';
$username = 'xxxxxxxx';
$password = 'xxxxxxxx';
$db_name = 'xxxxxxxx';

//Establishes the connection
$conn = mysqli_init();

mysqli_ssl_set($conn, NULL, NULL, "/cert/BaltimoreCyberTrustRoot.crt.pem", 

mysqli_real_connect($conn, $host, $username, $password, $db_name, 3306, 
if (mysqli_connect_errno($conn)) {
die('Failed to connect to MySQL: '.mysqli_connect_error());

//Run the Select query
printf("Reading data from table: \n");
$res = mysqli_query($conn, 'SELECT * FROM tbl_xxxx');
while ($row = mysqli_fetch_assoc($res)) {
   echo $row["ID"]. " : " . $row["XXXX"]."<br>";

//Close the connection
But when I use the connection string on my database class, I got this error:

Code: Select all

An attempt was made to access a socket in a way forbidden by its access permissions.
on a client browser. My database class is:

Code: Select all

public function open_connection() {
    $this->conn = mysqli_init();

    mysqli_ssl_set($this->conn, NULL, NULL, "/cert/BaltimoreCyberTrustRoot.crt.pem", NULL, NULL);

    mysqli_real_connect($this->conn, server, user, pass, database_name, 3306, MYSQLI_CLIENT_SSL, MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);

        echo "Problem in database connection:". mysqli_connect_error();
        $db_select = mysqli_select_db($this->conn, database_name);

        if (!$db_select) {
            echo "Problem in selecting database:". mysqli_connect_error();

Please note that the

Code: Select all

server, user, pass, database_name
is already defined with same value in the above code. Fyi, my test shows the

Code: Select all


Code: Select all

Problem in selecting database:
so the connection is fine. Is there anything I can do to properly select a database by using this class? Thank you.
