Answer 1

html :-
<input type="file" name="file" id="file" multiple>
PHP CODE:-
//Loop through each file
for($i=0; $i<count($_FILES['file']['name']); $i++) {
//Get the temp file path
$tmpFilePath = $_FILES['file']['tmp_name'][$i];
//Make sure we have a filepath
if ($tmpFilePath != ""){
//Setup our new file path
$newFilePath = "./uploadFiles/" . $_FILES['file']['name'][$i];
//Upload the file into the temp dir
if(move_uploaded_file($tmpFilePath, $newFilePath)) {
//Handle other code here
}
}
}
