    function myFunction($words,$chars)

    return $chars.$words;
}

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

foreach ($words as $key => $value) {

    $cond = ($key>0)?mb_substr($words[$key-1], 0,1):mb_substr(end($words),0,1);

    $result[] = myFunction(mb_substr($value,1),$cond);

}

$finalRes = implode(" ", $result);

echo $finalRes;

    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);
