Post-increment¶
Post-increment is the ++ operator, used on a variable, when it is placed after the variable. This means that the increment happens after the variable is read: in this case, the first echo displays 1, as the increment happens after the echo call.
There is also a post-decrement, which uses the operator --, and reduces the variable by 1.
Post-increment and post-decrement have a corresponding pre-increment and pre-decrement.
<?php
$a = 1;
echo $a++; // displays 2
echo $a; // displays 2
?>
