Different css styling for last element of a php array

Question

When looping through an array how can I create a different css div style for the last element to be output in my array.

for($i=0;$i<=count($productid);$i++){         


        

Answer 1

Just check if it is the last $productid

for(...)
{
    if ($i === (count ($productid) - 1))
        // Last one -> special CSS
    }
}

Also, DO NOT use count() in a FOR loop if you don't really have to. Just assign a value BEFORE and use it :

$count_temp  = count ($productid);
for ($i = 0; $i < $count_temp; ++$i)

And use this $count_temp again if the IF statement to check if it's the last element

Answer to comment :

How would this same method get the first element?

if ($i === 0)

Or

// Special CSS for $i = 0
// Start loop at 1 instead of 0
for ($i = 1; $i < $count_temp; ++$i)
