How does the choice between index.php and index.html impact the retrieval of variables via $_GET in PHP?

When using $_GET to retrieve variables in PHP, the choice between index.php and index.html impacts the ability to process PHP code. If the file is named index.html, the PHP code within it will not be executed, and therefore $_GET variables cannot be retrieved. To solve this issue, ensure that the file is named index.php so that PHP code can be processed and $_GET variables can be accessed. 

// index.php

// Retrieve a variable using $_GET
$variable = $_GET['variable_name'];

// Process the variable
echo "The value of the variable is: " . $variable;
