Why is it recommended to always use double quotes when accessing array elements in PHP?

Using double quotes when accessing array elements in PHP is recommended because it allows for the interpolation of variables within the string. This means that variables can be directly inserted into the string without the need for concatenation. Using double quotes also makes the code more readable and maintainable. 

// Example of accessing array elements with double quotes
$colors = ['red', 'blue', 'green'];
$index = 1;
echo "The second color is: $colors[$index]";
