Calling MySQL from PHP

Web pages on the UCL Web server which use PHP can access databases on the MySQL server. Full details of the PHP MySQL API (Application Program Interface) can be found in the on-line PHP manual at

Pages using PHP/MySQL can also be created using Dreamweaver MX.

A page such as the following example should be saved in a file with a .php extension. Note that PHP pages only work in the main UCL Web tree under, and not in users' personal web space. This example displays the names and ages in table people in database ucabwww, where the person's age is over 18.

<body bgcolor="white">
<table border="1">
# Connect to MySQL server
$conn = mysql_connect($host,$user,$password)
   or die(mysql_error());
# Select the database
mysql_select_db("ucabwww", $conn)
   or die(mysql_error());
# Send SQL query
$sql = "SELECT * FROM people WHERE age > 18 ORDER BY name";
$result = mysql_query($sql)
   or die(mysql_error());
# Fetch table rows, one by one, and display as HTML table rows
while ($row = mysql_fetch_assoc($result)) {
   echo "<tr><td>", $row['Name'], "</td><td>", $row['Age'],
