Creating a $varible from a string

[cesarcesar]

I am trying to dynamically create a variable name by crating a string of its name first. the problem is i can not find function to take a string and convert it into a variable that can be used. The variable I am trying to create is all ready there and has a value pulled from a DB, these variable are added below.

CODE-

<?

/***** Added for this post */

$SITE->Option4Total1s = 50;
$SITE->Option4Total1e = 100;
$SITE->Option4Total1x = 150;
$SITE->Option4Total2s = 200;
$SITE->Option4Total2e = 250;
$SITE->Option4Total2x = 300;

/****************************/

?> <table border="1" cellpadding="2" cellspacing="0">
<tr>
<td><b>Total Order Amount</td>
<td><b>Standard</b></td>
<td><b>Expedited</b></td>
<td><b>Express</b></td>
</tr>

<? for ($i = 1; $i < 12; $i++) { ?>
<tr>
<?

								$compile_name = "Option4Total".$i."s";

$Option4Totals = "$"."SITE->".$compile_name;

$compile_name = "Option4Total".$i."e";
$Option4Totale = "$"."SITE->".$compile_name;

$compile_name = "Option4Total".$i."x";
$Option4Totalx = "$"."SITE->".$compile_name;
?>
<td><input type="text" name="Option4Max1" value="<? echo $SITE->Option4Max1; ?>"></td>
<td>$<input type="text" name="Option4Total<? echo $i; ?>s" value="<? echo $Option4Totals; ?>"></td>
<td>$<input type="text" name="Option4Total<? echo $i; ?>e" value="<? echo $Option4Totale; ?>"></td>
<td>$<input type="text" name="Option4Total<? echo $i; ?>x" value="<? echo $Option4Totalx; ?>"></td>
</tr>
<? } ?>
</table>

Let's say you have the following:

$name = "paul";

You should be able to do this

$$name = "paul has a name";
echo $paul;  

You should get the following output:

paul has a name

im not sure this is correctYour answer is close but i cant get to work for me. let me put this in a shoter format-

<? // all pulled from a for loop just to have in mind.

$SITE->Option4Total1s = 50; // set the var
$i = 1; // fake the loop

$string = "SITE->Option4Total".$i."s";
echo $string;

// echo should return, 50
?>

How do i get $string to give me 50?

This will work:

$string = 'Option4Total' . $i . 's';
echo $SITE->{$string}; 

FWIW, using arrays is a much better idea.
