Decreasing one from a variable?

[FoxhoundX]

Is there an opposite of $string++?

I have a alpha string that I wish to take one off (f=e, etc)..any help?

Maybe something like this?

<?

$string = 10;
$sub = 1;
$answer = $string - $sub;

print($answer);

?>

Hope that helps! 🙂

$string-- ????

Subtracting one from an alpha retrieves the string as 0 before anything, so that doesnt work.

$string-- doesnt work. It doesn't spill any errrors, but it doesnt do anything to the string 😕

Here is what I am trying to do, perhaps someone has an alternate way..

<?
if(!isset($_POST['TEXT'])){
die('Nothing Entered to Encrypt!');
}
$text = $_POST['TEXT'];
if($text == ''){
die('Nothing Entered to Encrypt!');
}
$max = strlen($text);
echo 'The String <font color=red size=4>';
echo $text;
echo ' </font>Encrypted Is: <Font color=red size=4>';

$count = '0';
$cnt = '2';
$newstring = substr($text,$count,-1);


while($count != $max){
//here is where  Ineed it...
$newstring .= substr($text,$count,-1);
//This is to reverse the string..
while($count != $max){
$temp = substr($text,$count,1);
for ($i = 1; $i != $cnt; $i++) {
$temp++;
$temp++;
$temp++;
}
echo $temp;
$count++;
$cnt++;
}


?>

Is there no way to do this? 😕
