Question

a question about getting some random words out of a bigger string after it has been translated:

<?=__("water, chicken, banana, rice, bread, salt, cucumber, ananas, peach")?>

on my site currently outputs:

water, kip, banaan, rijst, zout, komkommer, ananas, perzik

now imagine I want to get just 3 words from that on random. How do I do that?

It’s important not to touch the words parts inside __(" & ") part! The translater cannot process when __($var) but ONLY when __("word1, word2, word3").

I imagine the best is to first put the the outcome into a string or array (this is how far I came please don’t laugh)

$translated = __("water, chicken, banana, rice, bread, salt, cucumber");
echo $translated;
# shuffle & echo 3 items

How do I proceed from here to randomly get 3 words out of $entireString ?

update

    $array = explode(',', $translated);
    $randomKeys = array_rand($array, 3);
    $translated = '';
    foreach(array_keys($randomKeys) as $key){
      $translated .= $array[$key].' ';  // use space or comma
    }

    echo $translated;

echos: water kip banaan always. so it does not seem to shuffle well?

Answer 1

you can use

$array = explode(',', $str);
$randomKeys = array_rand($array, 3);
$str = '';
foreach($randomKeys as $key){
  $str .= $array[$key].' ';  // use space or comma
}
