Open a Connection to the MySQL Server

Store the connection in a variable ($con) for later use in the script:

<?php
// Create connection
$con = mysql_connect("dbhost", "dbuser ", "dbpass ", "dbname");

// Check connection
if (mysql_connect_error())
{
echo "Failed to connect to MySQL: " . mysql_connect_error();
}
?>

Close a Connection


<?php
$con = mysql_connect("dbhost", "dbuser ", "dbpass ", "dbname");

// Check connection
if (mysql_connect_error())
{
echo "Failed to connect to MySQL: " . mysql_connect_error();
}

mysql_close($con);
?>
