php display blank and error on mysqli_fetch_array

Question

I receive a blank page when I try connect to mysql, based on the error. php doesn't like the 3rd line

$link = "SELECT * FROM `Table` WHERE `id`='$id'";
$results = mysqli_query($db,$link);
$qdata = mysqli_fetch_array($results);

This code is working on my old server, so mysqli_fetch_array seems absolute? Or did I miss something else on my php config?

Thanks!

This is the error message Fatal error: Call to undefined function mysqli_connect() in /opt/php_script/connect.php on line 14

Line 14 is

$link = "SELECT * FROM `Table` WHERE `id`='$id'";

Answer 1

Your mysqli extendion is not enabled. Check your php.ini , go to the extensions part and enable it.

Answer 2

This means the build of PHP you are using does not have mysqli support. You will have to recompile PHP with mysqli support (on Linux) or add the php_mysqli.dll extension to your php.ini file on Windows.

See Installation - mysqli on PHP.net for more information.
