Question

what does the assignment in this loop do? I don’t get the array notation in it :S

foreach($fieldvalues as $fieldvalue){
    $insertvalues[] = $fieldvalue;
 }

Answer 1

$insertvalues[] means insert a new item into the array, its a shortcut of array_push(). Its also preferred as it created lesser overhead whilst the PHP is working.

Additional:

For those who are unsure how the loop works.

foreach($fieldvalues as $fieldvalue)

every time the loop… loops, the value $fieldvalue becomes the next value a pointer is looking it in the array $fieldvalues – thus adding this to a new array `$insertvalues by means of the shortcut syntax mentioned above.
