在for循环中重新循环数组项[关闭]

Question

I have a for loop that checks for conditions and I want to know if I can re-run an item through the loop if it doesn't meet the condition after I make some changes to variables. is it possible to add something to my else statement that will allow me to re-run the same $item under new conditions?

$array_1 = array();
$arraynumber = 0;
foreach($test_array as $item) {
     if($item[2] == $test_array[$y][2]) {
          $array_1[$arraynumber][] = $item;
          $z++;
     } else {
          $arraynumber++;
          $y = $y+$z;
          $z=0;

          echo $item[2];
     }
}

The solution turns out to be this, just for those interested:

foreach($test_array as $item) {
if($item[2] == $test_array[$y][2]) {
  $array_1[$arraynumber][] = $item;
 $z++;
}elseif($item[2] == $test_array[$y+$z][2]){
$array_1[$arraynumber+1][] = $item;

 $y = $y+$z;
  $z=1;

  $arraynumber++;
}else{
$array_1[$arraynumber+2][] = $item;
 $z++;
 $y = $y+$z;
  $z=0;
  $arraynumber++;

echo $item[2];
}
}

re-run an item through the loop

You could use prev() which will set the internal data pointer 1 step back.

prev($test_array); //will re-run the current element in the next iteration
