What is the difference between -0, +0, and 0 in PHP?

In PHP, -0, +0, and 0 are all considered as the same value numerically, which is 0. However, they are represented differently in terms of their sign. To ensure consistency and avoid confusion, it is recommended to always use 0 as the standard representation of zero in your code.

// Example of using 0 as the standard representation of zero
$number = 0;
echo $number; // Output: 0
