Insert “element” among other “elements” of the array (loop) php

Question

my code causes the images to appear randomly within the page. But how to insert an \"element\" (in my case would be a div) between these images?

Answer 1

If you want to add a div(content) between those two pairs of images - add additional condition into your loop:

...
for ($i=0; $i<4; $i++) {
    if ($i == 1) echo '
some content ...
';
    echo '';
}
