Without cutted words:

/**
 *  Splits a string with words in equal parts (PHP7)
 *
 *  @since    1.0 DP0
 *  @version  1.0 DP0
 *
 *  @param    string    words   String with words
 *  @param    int       parts   How many parts needed
 *
 *  @return   array             Parts as rec. Array
 */

function split_words_into_parts( string $words, int $parts ) {

      $words_array  = explode( ' ', $words );
      $words_cnt    = count( $words_array );
      $per_part   = max( round( $words_cnt / $parts ), 1 );

      $result     = [];


      /*---  Splitting full array  ---*/

      for( $i = 0; $i < $parts; $i++ )
          $result[] = array_slice( $words_array, $i * $per_part, $per_part );

      return $result;
}
