PHP : Add word from array to string after every 5 words

Question

I've got a string and i wanted to put a word every after 5 words. The word is coming from array.

French History Maths Physics Spanish Chemistry Biology English DT Maths History DT Spanish English French RS

and i want to get 2 words from the array then insert it to the string above after 5 words.

$words = arrray(a, able, about, above, abst, accordance, according, accordingly, across, act, actually, added, adj);

Like this output :

French History Maths Physics Spanish a able about above abst Chemistry Biology English DT Maths according according accordingly across act Spanish English French RS.

Have you made any attempts at this yet, please add any code (non working code is fine) to the question. — Nigel Ren, Jul 13 '20 at 06:00
I have made any attempts yet. i don't know how to start it. Thank you for replying to my question — Marc Justin Rait, Jul 13 '20 at 06:01
but in your example, you add after every 5 words you add 5 words from the `array` instead of 2 or i misunderstanding? — Joseph, Jul 13 '20 at 06:03
There are resources around for [php explode: split string into words by using space a delimiter](https://stackoverflow.com/questions/18638753/php-explode-split-string-into-words-by-using-space-a-delimiter) which is at least a start. — Nigel Ren, Jul 13 '20 at 06:04
@Joseph Yes, but it's only the concept i wanted to show. sorry for inserting 5 words. — Marc Justin Rait, Jul 13 '20 at 06:05
You need to show us your best attempt (code) so we can take it from there. Edit your question, so the output sample is in _accordance_ with your desired outcome as per your description (i.e. is it _a word_, or _2 words_, or a variable number?). — jibsteroos, Jul 13 '20 at 06:28

$string = 'French History Maths Physics Spanish Chemistry Biology English DT Maths History DT Spanish English French RS';
$words  = array('a', 'able', 'about', 'above', 'abst', 'accordance', 'according', 'accordingly', 'across', 'act', 'actually', 'added', 'adj');
$result = [];

$xpld = explode(' ',$string);
if(!empty($xpld))
{
  $count = 0;
  for ($i=0; $i < sizeof($xpld) ; $i++) 
  {
    if ($i % 5 == 0 && $i > 0) 
    {
      for ($j=$count; $j < $count + 5 ; $j++) 
      {
        $result[] = @$words[$j];
      }
      $count = $j;
    }
    $result[] = $xpld[$i];
  }
}
$result = implode(' ',$result);
echo $result;

The code above works like the one in your example, but I don't know is it efficient or not, note that I used suppress @ to avoid your array words out of index

Thank you very much, this is the answer i'm looking for. – Marc Justin Rait Jul 14 '20 at 07:39 — Marc Justin Rait, Jul 14 '20 at 07:39
