What is the purpose of using the return statement in a PHP function like t1s1?

The purpose of using the return statement in a PHP function like t1s1 is to explicitly specify the value that the function should output or return when it is called. This allows the function to pass data back to the calling code, which can then be used for further processing or manipulation. Without the return statement, the function may not provide any output or the desired result.

function t1s1() {
    // Perform some operations here
    $result = 10; // Example result
    return $result;
}

// Call the function and store the returned value
$output = t1s1();

// Output the result
echo $output;
