[LAST EDIT] After some troubles with the last code, here a clean one.Hope that can help somebody.
// -- HTML --
//-- Using name="image[]" in the input file doesn't work. //-- Better if you use name="image1", name="image2", name="image3", etc..
<div class="container">
<label for="title">Title:</label>
<input type="hidden" name="MAX_FILE_SIZE" value="500000" />
<input type="file" class="form-control" name="image1" id="upload_file_pc" required><br /><br />

// -- PHP --
foreach($_FILES as $file){
$filesname = ($file["name"]); //-- Client file name
$target_dir = "upload/"; //-- Here you can add after the " /" something for recognize the file up.
$target_file = $target_dir . basename($filesname);
$filestmp = ($file["tmp_name"]);
$filessize = ($file["size"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if the image file is an actual image or fake image
if(isset($_POST["submit"])){
$check = getimagesize($filessize);
if($check !== false) {
$messagemerci = "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
}
else {
$messagemerci = "File is not an image.";
$uploadOk = 0;
}
}
// Check if the file already exists
if (file_exists($target_file)) {
$messagemerci = "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($filessize > 500000) {
$messagemerci = "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType !="jpeg" && $imageFileType != "gif" && $imageFileType != "pdf" ) {
$messagemerci = "Sorry, only JPG, JPEG, PNG, GIF & PDF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
$messagemerci = "Sorry, your file was not uploaded.";
// if everything is ok, try to upload the file
}
else {
if (move_uploaded_file($filestmp, $target_file)) {
$messagemerci = "The file ". basename( $filesname). " has been uploaded.";
}
else {
$messagemerci = "Sorry, there was an error uploading your file.";
}
}
};
Now I will make some security process inside it and it will be not so bad.
Thank for your time.

// -- Beginning --
I don't understand how to download multiple files from an HTML form using PHP.
I don't want to use this: <input type="file" name="" multiple>
One input to allow multiple files it's not something I want to use for the moment.
So let's start:
I can upload one file with this code:
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload the file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
But how can I upload multiple files?
I thought I needed:
foreach ($_FILES["image”]["tmp_name"] as $index){
//--something
}
But nothing...
I saw this answer from Okonomiyaki3000 here(arigatô by the way, with your answer I saw hope :)... )
$files = array_map('RemapFilesArray'
(array) $_FILES['attachments']['name'],
(array) $_FILES['attachments']['type'],
(array) $_FILES['attachments']['tmp_name'],
(array) $_FILES['attachments']['error'],
(array) $_FILES['attachments']['size']
);
function RemapFilesArray($name, $type, $tmp_name, $error, $size)
{
return array(
'name' => $name,
'type' => $type,
'tmp_name' => $tmp_name,
'error' => $error,
'size' => $size,
);
}
I understand the process but doesn't work for me...
I try everything but I don't understand how to loop every $_files[POST]
Maybe I made a mistake that I cannot see because I'm a newbie.
I also check other solutions and finally, I come here because of your reputation.
So here a complete example of what I tried before asking.
//-- In this case, I want to upload multiple files with an HTML form and a PHP action.
//-- I don't understand how to loop with each file in $_Files.
//-- I made 3 examples, working for 1 file upload but not for 4 files.
//-- Anyone can explain to me how it works. NOT JUST WRITING THE RIGHT WAY PLEASE.

[EDIT] Thank you to NiMusco for his help. Now I understand better how to see what is uploaded in $_FILES but when I put $_FILES['name'] in "$data" and echo "$data" I get "Array"...
So I tried something simple, maybe I did it wrong but for me it's work but I don't get what I expect.
Here :
?php
if(!empty($_FILES))
{
foreach($_FILES as $file)
{
$namefile = $file['name'];
echo $namefile;
}
}
?>".
But what I get is " Array ".... not the file name. here what I get when I do:
print_r($_FILES) :" Array
(
[image] => Array
(
[name] => Array
(
[0] => img_1.jpg
[1] => img_2.jpg
[2] => img_3.jpg
[3] => img_4.jpg
)
[type] => Array
(
[0] => image/jpeg
[1] => image/jpeg
[2] => image/jpeg
[3] => image/jpeg
)" etc...."
I think "Array" refer at this : "[name] => Array" of print_r ...
Maybe I need to go back to learn PHP from the beginning. I missed something for sure.
[EDIT] I FOUND THE SOLUTION WITH THE HELP OF NiMusco.
So here my full code who works for me:
