从值中停止不同的循环

Question

I have a problem concerning my script which allows me to take keys and values of an array ($array) and to add them to an existing array ($arraywithfourwords).

The problem I've encountered is that when I loop over $array, the loop does not break when I expect it to. In the case below, it should break when the value "A" is encountered.

For information, $arraywithfourwords is defined from the beginning, and $array is the array taken at random and to which I attempt to "match" the keys and values of this first array.

$arraywithfourwords before script :

[Aero] => D
[Blue] => V
[Almond] => Q
[Amazon] => X

$array:

[Aero] => D
[Blue] => V
[Almond] => Q
[Amazon] => X
[Android] => A   //STOP BREAK THE LOOP
[Cherry] => J    //Not continue
[Citrine] => P   //Not continue
[Dark] => M      //Not continue
[Celeste] => E   //Not continue

$fourthKey = [Amazon]

Script:

$passed = false;
foreach($array as $key => $value){
    if ($passed && $value != 'A' && $value != 'P')
    {
                $passed2 = 'valid';
                $arraywithfourwords[$key] = $value;

    }

    if ($key == $fourthKey && $value != 'A' && $value != 'P')
    {
                $passed = true;
    }
    if ($passed2 == 'valid') 
    {
                break;
    }

}

print_r($arraywithfourwords);

$arraywithfourwords after script:

[Aero] => D
[Blue] => V
[Almond] => Q
[Amazon] => X
[Cherry] => J //My problem

$arraywithfourwords after script that I search:

[Aero] => D
[Blue] => V
[Almond] => Q
[Amazon] => X

This will stop the loop when you find a 'stop' value :

$stopValues = array('A', 'P');

foreach ($array as $key => $value) {
  if(in_array($value, $stopValues)) {
    break;
  }
  elseif(!in_array($value, $arraywithfourwords)) { // prevent to have duplicated values
    $arraywithfourwords[$key] = $value;
  }
}
