Receiving array of values in GET request via PHP Api script [duplicate]

Question

I have written an API script in PHP which receives a single value for parameter 'id' and returns the corresponding entry in db.How can I receive an array of values for 'id' and return all corresponding entries?

if(@$_GET["id"]){
    @$id=$_GET['id'];

    $where="where id=".$id;
 }else{
    $id=0;
    $where="";
 }

PS I have only started working with PHP.

then start with prepared statements with paraeters to prevent sql injection see stackoverflow.com/questions/60174/… — nbk

have you created a instance of PDO or mysqli, then you can use this stackoverflow.com/questions/30354280/… — bhucho

It is bad practice to suppress error using @, instead, check it's existence with isset() function. Like this

if(isset($_GET["id"])){
           $id = $_GET["id"];
}

or

$id = isset($_GET["id"])? $_GET["id"] : 0;

Now, if your id post variable as an array of values. You can collect them using foreach, like this

if(isset($_GET["id"])){
   foreach($_GET["id"] as $id){
       echo $id; // use it as you want.
}
    }

I am assuming your id post variable and is a single dimension array.
