Question

I have the following code snippet.

$items['A'] = 'Test'; $items['B'] = 'Test'; $items['C'] = 'Test'; $items['D'] = 'Test';  $index = 0; foreach($items as $key => $value) {     echo '$index is a $key containing $value\n';     $index++; } 

Expected output:

0 is a A containing Test 1 is a B containing Test 2 is a C containing Test 3 is a D containing Test 

Is there a way to leave out the $index variable?

Answer 1

Your $index variable there kind of misleading. That number isn’t the index, your ‘A’, ‘B’, ‘C’, ‘D’ keys are. You can still access the data through the numbered index $index[1], but that’s really not the point. If you really want to keep the numbered index, I’d almost restructure the data:

 $items[] = array('A', 'Test'); $items[] = array('B', 'Test'); $items[] = array('C', 'Test'); $items[] = array('D', 'Test');  foreach($items as $key => $value) {     echo $key.' is a '.$value[0].' containing '.$value[1]; }
