How can the use of the "require" function in PHP affect the availability of parameters?

When using the "require" function in PHP to include a file, if the required file contains functions that expect certain parameters to be passed in, it can affect the availability of those parameters in the current scope. To solve this issue, you can pass the required parameters to the included file explicitly to ensure they are available within the functions. 

// main_file.php
$param1 = 'value1';
$param2 = 'value2';

require 'included_file.php';

// included_file.php
function myFunction($param1, $param2) {
    // Function logic using $param1 and $param2
}

myFunction($param1, $param2);
