Create / add up array with switch statements - php

Question

For readability and perfomance reasons, I'd like to build up an array with a switch statement instead of if-statements.
Consider the following if-statement:
$size = 2;
$array = array();
if($size >= 1) { array_push($array,'one','foo'); }
if($size >= 2) { array_push($array,'two','bar','barista'); }
if($size >= 3) { array_push($array,'three','zoo','fool','cool','moo'); }
It basically counts up from 1 to $size, it might be more readable and most likely a lot faster with a switch-statment...but how do you construct that ??
$step = 2;
$array = array();
switch($step)
{
case ($step>1): array_push($array,'one','foo');
case ($step>2): array_push($array,'two','bar','barista');
case ($step>3): array_push($array,'three','zoo','fool','cool','moo');
}
I tried leaving out the break, which didn't work - as the manual says:
In a switch statement, the condition is evaluated only once[...].
PHP continues to execute the statements until the end of the switch
block, or the first time it sees a break statement.
Anyway, anyone got an idea how to build up such an array with a switch-statement ??

Answer 1

Surely what you want can be achieved much more easily using
$array=range(1,$size);
Based on further coments and subsequent edits, something like:
$baseArray = $array(array('one'),
array('two','twoA'),
array('three','threeA','threeB'),
array(),
array('five'),
);
$step=2;
$array = array_slice($baseArray,0,$step);
and then flatten $array

Answer 2

Well, a switch statement would look like:
edit: the above doesn't work - let me take a look.
but in this example, you could just do:
$size = 2;
$array = range(1, $size); // Array ( [0] => 1 [1] => 2 )

Answer 3

$valuesIWant = array(1=>'one','two','three','four');
$array = array();
for ($i = $step - 1; $i > 0; $i--) $array[] = $valuesIWant[$i];
$array = array_reverse($array);
So if $step is 2, you get:
Array
(
[0] => one
)
...and if it is 4, you get:
Array
(
[0] => one
[1] => two
[2] => three
)
