Answer 1

I'm sure that your problem is somewhere else, but here's my solution, using preg_replace_callback :

$string = 'multiple


newline



convert




or replace';
$r = preg_replace_callback(
    '/' . PHP_EOL . '(' . PHP_EOL . '+)' . PHP_EOL . '/',
    function($v) {
        return PHP_EOL .PHP_EOL . implode(PHP_EOL . PHP_EOL, array_fill(0, strlen($v[1]), ' ')) . PHP_EOL . PHP_EOL ;
    },
    $string
);

echo $r;
