    $zeroText = true;
    $oneText = true;
    $twoText = true;
      
      foreach($array as $value){
      if($zeroText){
            echo 'zero Text Printing';
            echo '<br>';
            $zeroText = false;
        }
        if($oneText){
            echo 'one Text Printing';
            echo '<br>';
            $oneText = false;
        }
        if($twoText){
            echo 'two Text Printing';
            echo '<br>';
            $twoText = false;
        }

What you want, is called a control break. You compare the relevant property of your current loop item, with that of the previous one - and based on whether they are the same or not, you decide what to do.

Put your header texts into an array, so that their index in there corresponds with the values you got in your data array, then you can simply use that value to access the correct header.

$header = ['Zero Text Printing', 'One Text Printing', 'Two Text Printing'];

$array = [0,0,0,0,0,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,2];

$previous_value = -1;

foreach($array as $item) {
  if($previous_value != $item) {
    echo $header[$item] . '<br>';
  }
  echo $item . '<br>';
  $previous_value = $item;
}
