php increment and decrement
// Php increment and decrement: Just print it then understand $n =9; echo $n++; echo PHP_EOL; echo ++$n; echo PHP_EOL; echo --$n; echo PHP_EOL; echo $n--; echo PHP_EOL; echo "Another Example======\n"; $a = 7; $b = $a++; echo $b."\n".$a;
Here is what the above code is Doing:
1. $a = 7;
2. $b = $a++;
3. echo $b.”\n”.$a;
So, first $a is assigned 7.
Then $b is assigned $a++.
$a++ is a post-increment operator.
So, $b is assigned 7, and then $a is incremented to 8.
Then, $b and $a are printed.
