$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.
$ insertvalues []表示在数组中插入一个新项,它是array_push()的快捷方式。它也是首选,因为它在PHP工作时创建了较少的开销。
Additional:
For those who are unsure how the loop works.
对于那些不确定循环如何工作的人。
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.
每次循环...循环时,值$ fieldvalue成为指针在数组$ fieldvalues中查找它的下一个值 - 因此通过上面提到的快捷语法将它添加到新数组`$ insertvalues中。
