Shorten Array in PHP?

Question

I want to shorten an array so it only contains 30 elements. If for example I have an array of 100 elements is it possible to take it and chop of (as to speak) 70 of those elements?

Answer 1

Use array_slice to extract the range of elements you need.

$short_array = array_slice($my_big_array, 0, 30)

$short_array will have first 30 elements of $my_big_array

Usage:

$shortarray = array_slice($longarray, 0, 30);
