如何只保留数组的第一个数组？

Question

The title is a bit 'misleading, but the question is simple and I will try to explain what I'm trying to do. Typically to remove the indexes of an array I using unset, but in this case I have an array containing other arrays, each array is classified with an index. What I want to do is to keep only the first array and eliminate unset with everyone else, how?

Example structure

array(7) { 
           [0]=> array(14) { ... } 
           [1]=> array(14) { ... }
          }

I want keep only the array with 0 index, so the first array available. How do this?

Answer 1

reset sets the pointer to the first item in an array and returns it:

$item = reset($array);

$item will contain the array found in the first index.
