You may find this a little more intuitive. It only requires one function call to
$original = array( 'a', 'b', 'c', 'd', 'e' ); $inserted = array( 'x' ); // not necessarily an array, see manual quote array_splice( $original, 3, 0, $inserted ); // splice in at position 3 // $original is now a b c x d e
If replacement is just one element it is not necessary to put array() around it, unless the element is an array itself, an object or NULL.
RETURN VALUE: To be noted that the function does not return the desired substitution. The
$originalis passed by reference and edited in place. See the expression
