A simple shortcut method may be used to add or subtract 1 from a number.
<?php
$number = 10;
$number++; // that is the same as saying $number=$number+1;
echo "$number";
?>
$number = 10;
$number++; // that is the same as saying $number=$number+1;
echo "$number";
?>

Can you guess what you would put to decrease a number by one? For those who are having a brain fuzzy :
<?php
$number = 10;
$number--; // that is the same as saying $number=$number-1;
echo "$number";
?>
$number = 10;
$number--; // that is the same as saying $number=$number-1;
echo "$number";
?>
