i start learn php. please explain detail code write.

if don't need process words' length later, try this:

// file contents $text = file_get_contents('path/to/file.txt');    // break text array of words $words = str_word_count($text, 1);  // display text echo $text, '<br><br>';  // , every word it's length foreach ($words $word) {     echo $word, ' => ', mb_strlen($word), '<br>'; } 

but noticed, str_word_count() function has many issues utf-8 string (f.e. polish, czech , similar characters). if need those, suggest filtering out commas, dots , other non-word characters , using explode() $words array.
