PHP - Multiple upload files not saved with . txt extension

Question

galley.

I am trying to upload multiple files that accept all types of files and save with the correct extension, but in the files . txt it saved with extension . Plain, I tried to change this extension doing a check but it was in vain.

I’m a beginner in PHP, someone can help me Please?

Follow my current code:

<?php

if(isset($_FILES['file'])){
if(count($_FILES['file']['tmp_name']) > 0){
    for($q=0;$q<count($_FILES['file']['tmp_name']);$q++){

        $extension = $_FILES['file']['name'];
        $ext = pathinfo($extension, PATHINFO_EXTENSION);

        if ($ext == 'Text'){
            $ext = 'txt';
        }

        $filename = md5($_FILES['file']['name'][$q].time().rand(0,9999)).$ext;

        move_uploaded_file($_FILES['file']['tmp_name'][$q], 'files/'.$filename);

    }
}
}
?>

Had tried otherwise too:

if(isset($_FILES['file'])){
if(count($_FILES['file']['tmp_name']) > 0){
    for($q=0; $q<count($_FILES['file']['tmp_name']); $q++){

        $extension = $_FILES['file']['name'];
        $extension = explode('.', $extension);
        $extension[1];

        $filename = md5($_FILES['file']['name'][$q].time().rand(0,9999)).'.'.$extension[1];

        move_uploaded_file($_FILES['file']['tmp_name'][$q], 'files/'.$filename);

    }
}
}

If I do the same procedure for single file upload it saves properly as . txt:

$file = $_FILES['file'];

if(isset($file['tmp_name']) && !empty($file['tmp_name'])){

$extension = $_FILES['file']['name'];
$extension = explode('.', $extension);
$extension[1];

$filename = md5(time().rand(0,9999)).'.'.$extension[1];

move_uploaded_file($file['tmp_name'], 'files/'.$filename);
}

Any hints as to why it’s going wrong? Thanks in advance.

Answer 1

Missed per file index like you did on md5:

Of:

$extension = $_FILES['file']['name'];

To:

$extension = $_FILES['file']['name'][$q];
