PHP: Tips of the Day

Have a look at $_SERVER[‘REQUEST_URI’], i.e.

$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

(Note that the double quoted string syntax is perfectly correct)

If you want to support both HTTP and HTTPS, you can use

$actual_link = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Editor’s note: using this code has security implications. The client can set HTTP_HOST and REQUEST_URI to any arbitrary value it wants.

Get_client_info

In this article, we will focus on the mysqli_get_client_info() function in PHP, which is used to return the MySQL client library version. We will provide you with an overview of the function, how it works, and examples of its use.

Introduction to the mysqli_get_client_info() function

The mysqli_get_client_info() function is a built-in function in PHP that is used to return the version of the MySQL client library that is currently used by the MySQLi extension. This function is useful when you need to know the version of the MySQL client library.

How to use the mysqli_get_client_info() function

Using the mysqli_get_client_info() function is very simple. You just need to call the function on a valid MySQLi connection. Here is an example:

 $mysqli = mysqli_connect("localhost", "username", "password", "database"); $client_info = mysqli_get_client_info($mysqli); printf("MySQL client library version: %s\n", $client_info); mysqli_close($mysqli); ?>

In this example, we call the mysqli_connect() function to connect to a MySQL database with a username and password. We then call the mysqli_get_client_info() function on the MySQLi connection to get the version of the MySQL client library. We then output the version using the printf() function.

Conclusion
