Without doing so myself, I'm 99% sure that count($issue) will give you the answer you're looking for -- i.e. the number of different subscripts in the first dimension. From your description of how you expect count() to work, I suspect you're labouring under a misapprehension about how PHP arrays are built: in this case, $issue is an array of (x+1) elements, indexed from 0 to x, each element of which just happens to contain an array itself; it's not a single array of (x+1)*(no. of "string" subscripts) elements. This means you can do something like $current = $issue[0] and $current will be the array of string-subscripted elements contained in $issue[0]. > My problem is I need to loop through these. Well, you don't need to know how many there are to do this -- just use foreach: foreach ($issue as $n=>$elements): // in here, $elements['number']==$issue[$n]['number'], etc. endforeach; Cheers!
