Storing only certain $_GET request values

Currently I have this code that stores all $_GET requests:

  $array_name = array();
  foreach ($_GET as $key => $value) {
      $array_name[] = "'%".escape_string($value)."%'";
  }

My goal is to somehow only store certain values, if for example I have 5 different $_GET request, named 1,2,3,4 and 5. I only want to store 1-3 in this array. How would this be possible?

Slightly different approach to the other answers. $keysToStore is an array of the keys you want to store.

The foreach loop then pulls these values from the $_GET array rather than looping the entire array.

$keysToStore = [1, 2, 3];

$array_name = [];
foreach ( $keysToStore as $key ) {
    $array_name[] = "'%" . escape_string( $_GET[$key] ) . "%'";
}

Edit: can check isset inside the loop if keys are not validated elsewhere.

$keysToStore = [1, 2, 3];

$array_name = [];
foreach ( $keysToStore as $key ) {
    if ( isset( $_GET[$key] ) ) {
        $array_name[] = "'%" . escape_string( $_GET[$key] ) . "%'";
    }
}

For this, you need to add check on $key, that $key has value 1 or 2 or 3. Sample code is this:

 $array_name = array();
 foreach ($_GET as $key => $value) {
    if($key == '1' || $key == '2' || $key == '3'){
      $array_name[] = "'%".escape_string($value)."%'";
    }
 }

Or the other sample code is:

 $array_name = array();
 foreach ($_GET as $key => $value) {
     if(in_array($key, array(1, 2, 3))){
      $array_name[] = "'%".escape_string($value)."%'";
    }
 }

Here 1 , 2 and 3 is key of $_GET. Sample input is: $_GET['1'] = 'Ghazal' , $_GET['2'] = 'Taimur' , $_GET['3'] = 'Malik' , $_GET['4'] = 'Test' , $_GET['5'] = 'City'

You can get the intersection of an array of keys you want:

foreach(array_intersect_key($_GET, array_flip([1,2,3])) as $value) {
      $array_name[] = "'%".escape_string($value)."%'";
}

$array_name = array();
foreach ($_GET as $key => $value) {
  if(in_array($key, array(1, 2, 3)))
    $array_name[] = "'%".escape_string($value)."%'";
  }
}

It this what you are looking for?
