use logic inside of an array?

imimin

I need help in getting a php script I have been working on for a while finished. I came to a stopping point (brick wall) today when I tried to execute flow control inside of an array. Can someone please tell me if it is possible to use logic inside of an array?

An example of what I would like to do is:

$shippingCost = $baseShippingCost * $shippingBoxArr['numberOfBoxes'];

$shippingBoxArr is an arrray and I would like to apply the following logic while the array "runs", but am not sure how to do it:

if ($endTotalShippingCost = ('$dryIceCost + $totBoxCost + $ups_res_charge + $ups_dist_charge')) {$endTotalShippingCost=1000000;}

else {$endTotalShippingCost=$endTotalShippingCost;}

I would appreciate any help I can get on this!

I'm not sure how to answer this until you explain what you mean by "while the array 'runs'." Do you want to do a foreach loop, a while loop, an array_walk(), or what?

I am not sure howto handle this (I am fairly new to programming). I have the following code:

$shippingCost = $baseShippingCost * $shippingBoxArr['numberOfBoxes'];

that I need to apply the following logic to (or something similar):

	if ($endTotalShippingCost = ('$dryIceCost + $totBoxCost + $ups_res_charge + $ups_dist_charge')) {$endTotalShippingCost=1000000;}

else {$endTotalShippingCost=$endTotalShippingCost;}

***The idea here is to display (fill variable) the results of the array that satisfy the logic.

If this does not make sense, please ask me, I appreciate your help.

Thank you!

What I mean by

"while the array 'runs'."

is when the array code executes I would like to apply some logic to the array values (I am not sure if this is possible or if i should take a different approach).

Well, arrays do not "execute". They are simply structures for storing data. By themselves they do not "do" anything.

Certainly you can use results of an arithmetic expression to set or alter the values of an array. You can even use a PHP function like [man]array_walk/man to apply a function to each member of an array.

THANK YOU!

When you say:

apply a function to each member of an array

what do you mean by member? Are you talking about each key, value set?

Yes. Not sure if that is the best "technical" term, maybe array "element" would be better?
