Example

Example 1. Object oriented style

<?php

/* create a connection object which is not connected */
$mysqli = mysqli_init();

/* set connection options */
$mysqli->options(MYSQLI_INIT_COMMAND, "SET AUTOCOMMIT=0");
$mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 5);

/* connect to server */
$mysqli->real_connect('localhost', 'my_user', 'my_password', 'world');

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

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

$mysqli->close();
?>

Example 2. Procedural style

<?php

/* create a connection object which is not connected */
$link = mysqli_init();

/* set connection options */
mysqli_options($link, MYSQLI_INIT_COMMAND, "SET AUTOCOMMIT=0");
mysqli_options($link, MYSQLI_OPT_CONNECT_TIMEOUT, 5);

/* connect to server */
mysqli_real_connect($link, 'localhost', 'my_user', 'my_password', 'world');

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

printf ("Connection: %s\n.", mysqli_get_host_info($link));

mysqli_close($link);
?>

The above examples would produce the following output:

Connection: Localhost via UNIX socket
