Question

I’m trying to sort everything out using array & loops
lets say this is an array,

$arr = array('One','Two','Three','Four','Five','Six');

i want to select first three of them to be used as
$arr[0], $arr[1] and $arr[2]
this ends up with one,two,three
i want to use the same for next 3..
something to break it and use the same 0 1 2 index again to return second three
here’s an example to explain more,

$arr = array('One','Two','Three','Four','Five','Six');

  echo $arr[0].$arr[1].$arr[2]; // OneTwoThree
        break; // < ??
  echo $arr[0].$arr[1].$arr[2]; // FourFiveSix

also, i want to use it with foreach loop

$arr = array('One','Two','Three','Four','Five','Six');
  foreach($arr as $num){
  echo $num; // OneTwoThree
   if($something == 3){ // < ??
        break; // < ??
    }
  echo $num;   // FourFiveSix
   }

and what im trying to do is using each three arrays of the array to use them later

Answer 1

Use array_chunk and loop over the result:

foreach(array_chunk($arr, 3) as $a) {
  echo $a[0], $a[1], $a[2];
}

Here it is with added linebreaks:

foreach(array_chunk($arr, 3) as $a) {
  echo $a[0], $a[1], $a[2], "<br>\n";
}

Note: The last element may have less than three elements! A possible fix for this is to use implode to concatenate the elements:

foreach(array_chunk($arr, 3) as $a) {
  echo implode('', $a), "<br>\n";
}
