$_GET and isset() url response Json - php

Question

I have use a lot of answers here to solve almost everything, but i can't figure out how to accomplish this;
I use PHP to get data from my MySQL, and encode to json with url request, so wen I go to miweb. com /_js/ajax/load_content.php?f=1
I get a perfect response from my databesa and echo to json encode, 1 means user with id number 1
my response looks like this:
[{"i":"1","n":"Azul","p":"_imgs\/site\/iconos\/0-100\/22\/activo\/ico_00022_138.jpg"}]
and if i go to miweb. com/_js/ajax/load_content.php?f=2 i will get
[{"i":"2","n":"Lety","p":"_imgs\/site\/iconos\/0-100\/87\/activo\/ico_00087_138.jpg"}]
what i need to accomplish is to go to ?f=1,2
miweb.com /_js/ajax/load_content.php?f=1,2 and get the response in same json like this
[{"i":"1","n":"Azul","p":"_imgs\/site\/iconos\/0-100\/22\/activo\/ico_00022_138.jpg"},
{"i":"2","n":"Lety","p":"_imgs\/site\/iconos\/0-100\/87\/activo\/ico_00087_138.jpg"}]
this is my php scrip:
require '../../system/config.php';
if( isset($_GET['h']) ) {
get_ficha($_GET['h']);
} else {
die("Solicitud no válida.");
}
function get_ficha( $id) {
// CONECCION DATABASE//
$database = new mysqli(HOST, USER, PASS, DBNAME);
if($database->connect_errno) {
die("No se pudo conectar a la base de datos");
}
mysqli_set_charset($database, "utf8");
//Sanitize ipnut y preparar query
if( is_array($id) ) {
$id = array_map('intval', $id);
$promo = "WHERE `ID` IN (" . implode( ',', $id ) . ")";
} else {
$id = intval($id);
$promo = "WHERE `ID` = " . $id;
}
if ( $result = $database->query( "SELECT * FROM (ficha)" . $promo) ) {
if( $result->num_rows > 0 ) {
$promo = array();
while( $row = mysqli_fetch_array($result))
{
$id=$row['id'];
$nombre=$row['nombre'];
$icono=$row['ico_138'];
$promo[] = array(
'i'=> $id,
'n'=> $nombre,
'p'=> $icono
);
}
} else {
$promo = array(
);
}
$result->close();
} else {
$promo["success"] = false;
$promo["data"] = array(
'message' => $database->error
);
}
header('Content-type: application/json; charset=utf-8');
echo json_encode($promo, JSON_UNESCAPED_UNICODE);
$database->close();
}
exit();

You need to explode the get variable
get_ficha(explode(',', $_GET['h']));
Then in your function
if( is_array($id) && count($id) > 1) {
$id = array_map('intval', $id);
$promo = "WHERE `ID` IN (" . implode( ',', $id ) . ")";
} else {
$id = intval($id);
$promo = "WHERE `ID` = " . $id;
}
