Need help translating from pseudo code

[tryin_to_learn]

I have variables called preConSA1, preConSA2, preConSA3 and preConSA4. Each can have an integer value of from 1 to 4. What I'd like to do is loop through the values like this:

if ($preConSAx = 1) {
$preConSAx = $preConFirstChoice;
} else if (preConSAx = 2) {
$preConSAx = $preConSecondChoice;
} else if (preConSAx = 3) {
$preConSAx = $preConThirdChoice;
} else if (preConSAx = 4) {
$preConSAx = $preConFourthChoice;
}

I'm not even sure I've written the pseudo code right, but basically, what I'm trying to do is find a short-cut way to assign each of the 4 preConSA variables to its respective choice variable. I could do it the long way -- just writing the code block out 4 times -- one for each variable. But I figured there was a more eloquant way to do it. Anyone?

You can put the "preConSA1, preConSA2, preConSA3 and preConSA4" in an array
and then "$preConFirstChoice, $preConSecondChoice, ..." in a second array and
then use a loop to do the assignment :

$preCon_array[0] = $preConSA1;
$preCon_array[1] = $preConSA2;
$preCon_array[2] = $preConSA3;
$preCon_array[3] = $preConSA4;

$Choice_Array[0] = $preConFirstChoice;
$Choice_Array[1] = $preConSecondChoice;
$Choice_Array[2] = $preConThirdChoice;
$Choice_Array[3] = $preConFourthChoice;

for ($i=0;$i<4;$i++)
{   

    $result[$i] = $ChoiceArray[$preCon_array[$i]];
}

Instead of $result[] you can use $preCon_array[] again if you want.

Excellent, herve. That works, thanks.
