The explode function will get an array of words in the sentence, and then you will calculate the length of each word, you can through strlen

  • still need to get rid of punctuation marks!) - Kryshtop
  • then I paraphrase: as from the sentence "hello, my name is Alakai!" - pull out {"hello,", "me,", "name is", "Alakai". } - Kryshtop
  • You can replace the commas with spaces first, and then as I described above) - quaresma89

For lovers of the functional approach:

 $input = 'Fooo bar bazzz, фыва-олдж.'; $longest = array_reduce(preg_split('/[^a-zа-яё]+/ui', $input), function ($longest, $curr) { return mb_strlen($longest) < mb_strlen($curr) ? $curr : $longest; }, ''); echo($longest); // "bazzz" 
     $words = explode(" ", preg_replace("/[^A-ZА-ЯЁ ]/ui", " ", $str)); $long = ""; foreach ($words as $word) $long = (mb_strlen($word) > mb_strlen($long)) ? $word : $long; echo $long;

      The range of characters AZ (as, however, А-ЯЁ ) in the regular expression is redundant, because The case-insensitive flag is specified. - Dmitriy Simushev
