How can code readability and performance be improved by storing the result of the date function in a variable before using it in a loop in PHP?

When using the date function within a loop in PHP, it is more efficient to store the result in a variable before entering the loop. This helps improve code readability and performance by reducing the number of function calls within the loop. By storing the date value in a variable outside the loop, you only need to call the function once and then reuse the variable in each iteration of the loop. 

$date = date('Y-m-d'); // Store the current date in a variable

for ($i = 0; $i < 10; $i++) {
    echo "Today's date is: " . $date . "<br>";
    // Other loop operations using the stored date
}
