I use this php code to connect to my databse and retrieve the table food. I am able to connect to the database but no retrieve the table. I get this as a result: Host information: site.ipagemysql.com via TCP/IP Default database is database. Is there something wrong with my code?


    $mysqli = new mysqli("site.ipagemysql.com", "user", "pass", "database");

    /* check connection */ 
    if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());

    printf("Host information: %s\n", $mysqli->host_info);

$result = mysqli_query($mysqli, "SELECT DATABASE()");
    $row = mysqli_fetch_row($result);
    echo "<br />";
    printf("Default database is %s.\n", $row[0]);

$query = "SELECT * FROM example"; 

$result2 = mysqli_query($mysqli,$query) or die(mysql_error());

while($row2 = mysqli_fetch_array($result2, MYSQLI_BOTH)){
    echo $row2['food']. " - ". $row2['calories'];
    echo "<br />";

This is one of the most common ways to connect & return data from a mysqli database

// Database parameters
    $db_host = 'database_host';localhost??
    $db_user = 'database_user';
    $db_pass = 'database_password';
    $db_name = 'database_name';
// Connect to the database  
    $mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
    if (mysqli_connect_errno()) {
        printf("connect failed: %s\n", mysqli_connect_error());
// Query database
    $query = "SELECT * FROM example";
    $result = $mysqli->query($query) or die($mysqli->error.__line__);
// Loop through results
    if($result->num_rows > 0) {
        while($row = $result->fetch_assoc()) {
            echo $row['food']. " - ".$row['calories'];
            echo "<br">;    
    else {
        echo 'No results';  
// Close connection

Thank you, All online tutorials use mysql_connect(), How where I supposed to know that mysqli_connect() is better? –  Conrad C Nov 24 '12 at 19:50
