There's many different ways to solve this. Here, I am putting the first letters of each word into one array, the rest into another. (Using mb_ string functions, makes this work with UTF-8 & letters outside of the base Latin range.)

Then I "rotate" the first letters array by one position, using array_pop and array_unshift, and then the result gets combined again.

$words = explode(" ", "Lorem Ipsum is simply dummy text of the printing and typesetting industry");

foreach($words as $word) {
    $firstLetters[] = mb_substr($word, 0, 1);
    $otherLetters[] = mb_substr($word, 1);
}

array_unshift($firstLetters, array_pop($firstLetters));

foreach($firstLetters as $key => $firstLetter) {
    $result[] = $firstLetter . $otherLetters[$key];
}

echo implode(' ', $result);
