Can you explain the concept of incrementing and decrementing variables in PHP?

Incrementing and decrementing variables in PHP refers to increasing or decreasing the value of a variable by 1. This is commonly done using the ++ (increment) and -- (decrement) operators. Incrementing a variable means adding 1 to its current value, while decrementing means subtracting 1. 

// Incrementing a variable
$number = 5;
$number++;
echo $number; // Output: 6

// Decrementing a variable
$number--;
echo $number; // Output: 5
