Here's the code. This is a simple code to connect to mysql. Bare in mind PHP can connect to other database also. I am assuming you have the database and datatables in place
// First the connection string to connect php to a database say mysql database
// These are default settings, please change to your convenience
$host = "localhost"; $user="root";$password="";
$connect = mysql_connect($host, $user, $password);
// Fail-safe statement
if(!$connect)
{
die("Cannot connect to mysql database: ".mysql_error());
}
// Selecting the database
mysql_select_db("my_db"); // put name of your db in place of my_db
$select = mysql_query("SELECT * FROM table_name"); // put name of yr table in place of table_name
// fail-safe measure
if(!$select)
{
echo "Error fetching data: ".mysql_error();
}
else
{
while($fetch = mysql_fetch_array($select))
{
// Replace col_1, col_2 etc with your name of your table column headings
echo $fetch["col_1"]."
";
echo $fetch["col_2"]."
";
echo $fetch["col_3"];
}
}
?>
