What PHP function can be used to read the content of the browser address bar and assign it to a variable?

To read the content of the browser address bar and assign it to a variable in PHP, you can use the $_SERVER['REQUEST_URI'] superglobal variable. This variable contains the URI (Uniform Resource Identifier) that was requested by the client. By accessing this variable, you can retrieve the content of the browser address bar and store it in a variable for further processing.

$address_bar_content = $_SERVER['REQUEST_URI'];
echo $address_bar_content;
