Example#1 Object oriented style

<?php
$mysqli 
= new mysqli("localhost""my_user""my_password""world");

/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}
 
$query "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if (
$result $mysqli->query($query)) {

    
/* fetch object array */
    
while ($obj $result->fetch_object()) {
        
printf ("%s (%s)\n"$obj->Name$obj->CountryCode);
    }

    
/* free result set */
    
$result->close();
}

/* close connection */
$mysqli->close();
?>

Example#2 Procedural style

<?php
$link 
mysqli_connect("localhost""my_user""my_password""world");

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

$query "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if (
$result mysqli_query($link$query)) {

    
/* fetch associative array */
    
while ($obj mysqli_fetch_object($result)) {
        
printf ("%s (%s)\n"$obj->Name$obj->CountryCode);
    }

    
/* free result set */
    
mysqli_free_result($result);
}

/* close connection */
mysqli_close($link);
?>
