This may come as a bit of a shock to you, but PHP's arrayfunctions can do a lot more than just count the elements of an array oriterate through key-value pairs. This article takes an in-depth look atPHP's less well-known array manipulation tools, illustrating how they canbe used to write tighter, more efficient code...and have some fun in thebargain as well!
PHP allows you to extract a subsection of the array with the array_slice() function, in much the same way that the substr() function allows you to extract a section of a string. Here's what it looks like:
array_slice(array, start, length)
where "array" is an array variable, "start" is the index to
begin slicing at, and "length" is the number of elements to return from "start".
