Question

$example = array('First','Second','Third','Fourth','Fifth',...

The code below will unset the third element in $example.

unset($example[2]);

How can I unset all of the elements past the third element?

I want $example‘s value to be this afterwards:

$example = array('First','Second','Third');

Answer 1

Don’t use unset, use array_splice:

$example = array('First','Second','Third','Fourth','Fifth');
array_splice($example,3);
//$example = array('First','Second','Third');
