Recursive php function, to split long words:

/**
 * Cut words to max char, in a text
 *
 * @param    string text        Text to check
 * @param    integer maxChar    Max word length
 * @return   string             Verified text
 */
function checkWordLength($text, $maxChar=50) {

    $arrText = explode(' ', $text);
    foreach ($arrText as $key=>$t) {
      if (strlen($t)>$maxChar) {
        $arrText[$key] = chunk_split($t, $maxChar, ' ');
      }
    }

    return implode(' ', $arrText);
}

Use:

$text = checkWordLength($text);
