Strict Standards message on php array

Question

I currently am getting the following error message when splitting out array values by character: Strict Standards: Only variables should be passed by reference

This is my array:

array(6) { [0]=> string(8) "2390:SS0" [1]=> string(8) "2391:SS1" [2]=> string(9) "2392:SS11" [3]=> string(7) "250:BS1" [4]=> string(8) "251:BS10" [5]=> string(8) "252:BS11" }

This is my php:

foreach ($postcodes as $key => $value)
{
  $postcode_ids     = current(explode(':', $value));
  $postcode         = next(explode(':', $value));
}

The notice seems to appear on the next line? Any ideas or pointer would be great. Thanks.

next() modifies the array that you pass in. It is passed by reference. Therefore you cannot use

next( [expression] );

but only

next( [variable] );

To simplify your code, replace

 $postcode_ids     = current(explode(':', $value));
 $postcode         = next(explode(':', $value));

with

 list($postcode_ids, $postcode) = explode(':', $value);

Im not sure how I would split the value of the array, if I can use next?

Fantastic, works great. I have never seen this array function before it will come in very handy.
