[RESOLVED] put element in array

[alirezaok]

i have an array:

$input = array("red", "green", "blue", "yellow");

i want to put "<br>" as an element between array elements

output must:

Array
(
[0] => red
[1] => <br>
[2] => green
[3] => <br>
[4] => blue
[5] => <br>
[6] => yellow
)

what do i do?

thanks

A simple foreach:

$input = array("red", "green", "blue", "yellow"); 
$i=1;
$tmp = array();
foreach($input as $key=>$val)
{
    if($i%2 == 0)
        $tmp[] = '<br />';

$tmp[] = $val;

$i++;
}

I'm not sure why you'd want to do this though. You can get a string with the <br /> element in between them simple enough using:

$string = implode('<br />', $input);

But whatever your fancy 😉 Oh, and the above foreach doesn't worry about the keys of the old array. So associative arrays would be no good going through that.
