Script language for dynamic web-pages. The syntax and concepts used are similar to Perl
- $conn = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname, $dbport) or die ('Error connecting to mysql');
- Open database connection
- $result = mysqli_query($conn,$query) or die('Error, retrieve failed');
- Execute a query on the opened connection
- $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
- Fetch a row as hash
- $row = mysqli_fetch_array($result, MYSQLI_NUM);
- Fetch a row as array

<?php

}
?>
