How can the $_GET superglobal be used to convert a string to an integer in PHP?

To convert a string to an integer in PHP using the $_GET superglobal, you can use the intval() function to explicitly cast the value to an integer. This is important because values obtained from $_GET are always treated as strings by default. By using intval(), you can ensure that the value is properly converted to an integer for further processing. 

// Get the value from the $_GET superglobal
$value = $_GET['value'];

// Convert the string value to an integer using intval()
$intValue = intval($value);

// Now $intValue will contain the integer value of the input string
