Example #1 mysqli_connect() example

<?php
$link 
mysqli_connect("127.0.0.1""my_user""my_password""my_db");

if (!
$link) {
    echo 
"Error: Unable to connect to MySQL." PHP_EOL;
    echo 
"Debugging errno: " mysqli_connect_errno() . PHP_EOL;
    echo 
"Debugging error: " mysqli_connect_error() . PHP_EOL;
    exit;
}

echo 
"Success: A proper connection to MySQL was made! The my_db database is great." PHP_EOL;
echo 
"Host information: " mysqli_get_host_info($link) . PHP_EOL;

mysqli_close($link);
?>

The above examples will output something similar to:

Success: A proper connection to MySQL was made! The my_db database is great.
Host information: localhost via TCP/IP
