file_put_contents multiple image upload through API in PHP - php

Question

I am trying to upload multiple images through a PHP API.
When uploading, the data sending returns success, but it only uploads the names of the images to the Database and the files are not saved on the server side.
I tried to specify separate paths to decode, and then I used the file_put_contents function, but nothing uploads correctly to the server.
if($_SERVER['REQUEST_METHOD']=='POST'){
$pic = $_POST['pic'];
$random = random_word(20);
$path = "grocery/item_img/".$random.".jpg";
$actualpath = "$random.jpg";
$actualpath1 = "$random1.jpg";
$actualpath2 = "$random2.jpg";
$sql = "INSERT INTO item (`pic`, `pic1`, `pic2`)
VALUES (NULL, '$actualpath', '$actualpath1', '$actualpath2')";
class emp{}
if(mysqli_query($koneksi,$sql)){
foreach ($_POST['pic'] as $name) {
file_put_contents($path, $name);
}
echo json_encode(array( 'success' => 1,'message'=>'Item Added Successfully'));
}
else{
echo json_encode(array( 'success' => 0,'message'=>'Failed to Add Item Image'));
}
}
function random_word($id = 20){
$pool = '1234567890abcdefghijkmnpqrstuvwxyz';
$word = '';
for ($i = 0; $i < $id; $i++){
$word .= substr($pool, mt_rand(0, strlen($pool) -1), 1);
}
return $word;

SOLVED
foreach gives Invalid argument supplied
when edits it to
foreach ((array) $pic as $image) {
...
}
error gone but still no uploads
then tried
move_uploaded_file($_FILES["pic"]["tmp_name"], $path1);
give error of :
Undefined index: pic
then edits to :
if (isset($_FILES['foto'])) {
move_uploaded_file($_FILES["foto"]["tmp_name"], $path1); }
error gone but won't upload
tried to edit the file_put_contents
to the param of pic1
it uploaded the second pic ,,,
so below is the working code which uploads the three images while storing their paths to the DB
anyway to make it neat while working
if($_SERVER['REQUEST_METHOD']=='POST'){
$pic = $_POST['pic'];
$pic1 = $_POST['pic1'];
$pic2 = $_POST['pic2'];
$random = random_word(20);
$random1 = random_word(20);
$random2 = random_word(20);
$path = "../item_img/".$random.".jpg";
$actualpath = "$random.jpg";
$actualpath1 = "$random1.jpg";
$actualpath2 = "$random2.jpg";
//upload files
$path1 = '../item_img/'.$actualpath;
$path2 = '../item_img/'.$actualpath1;
$path3 = '../item_img/'.$actualpath2;
$sql = "INSERT INTO item (`pic`, `pic1`, `pic2`)
VALUES (NULL, '$actualpath', '$actualpath1', '$actualpath2')";
class emp{}
if(mysqli_query($koneksi,$sql)){
file_put_contents($path1,base64_decode($pic));
file_put_contents($path2,base64_decode($pic1));
file_put_contents($path3,base64_decode($pic2));
}
echo json_encode(array( 'success' => 1,'message'=>'Item Added Successfully'));
}
else{
echo json_encode(array( 'success' => 0,'message'=>'Failed to Add Item Image'));
}
}
function random_word($id = 20){
$pool = '1234567890abcdefghijkmnpqrstuvwxyz';
$word = '';
for ($i = 0; $i < $id; $i++){
$word .= substr($pool, mt_rand(0, strlen($pool) -1), 1);
}
return $word;
