How to Upload the Same File in Different Names for Each Users Using Foreach

Question

other queries working through the foreach loop.but file upload for 1st index of array.this is not multiple file upload.i wanna upload same file in different names for each users.

    foreach($_POST['groupmem'] as $user){
    //Some Queries

    $filename2 = str_replace(" ", "_","{$user}.{$_FILES['proposal']['name']}");
    $destination2 = '../img/proposal/' . $filename2;
    $extension2 = pathinfo($filename2, PATHINFO_EXTENSION);
    $file2 = $_FILES['proposal']['tmp_name'];
    $size2 = $_FILES['proposal']['size'];
    if (!in_array($extension2, ['zip', 'pdf', 'docx'])) {
        echo "You file extension must be .zip, .pdf or .docx";
    } elseif ($_FILES['proposal']['size'] > 200000000) { // file shouldn't be larger than 200Megabyte
        echo "File too large!";
    } else {
        if (move_uploaded_file($file2, $destination2)) {
            $sql = "UPDATE project SET proposal_name='$filename2' WHERE u_id='{$user}' ";
            if (mysqli_query($conn, $sql)) {
                echo "File uploaded successfully";
            }
        } else {
            echo "Failed to upload file.";
        }
    }
    }

you need to do only the first upload and then copy files with diferent filenames after this move_uploaded_file — Antonio Abrantes, May 03 '20 at 02:00

Thanks for the knowing.. @Dharman how i jump through that kind of SQL injections except mysqli_real_escape_string. — Vishva Madumal, May 07 '20 at 22:41
Use placeholders and parameters. See for example here: https://phpdelusions.net/sql_injection and https://stackoverflow.com/questions/7537377/how-to-include-a-php-variable-inside-a-mysql-statement — Dharman, May 07 '20 at 22:42

you can not do move_uploaded_file inside the loop

$user1 = $_POST['groupmem'][0];
$filename1 = str_replace(" ", "_","{$user1}.{$_FILES['proposal']['name']}");
$destination1 = '../img/proposal/' . $filename1;
$extension1 = pathinfo($filename1, PATHINFO_EXTENSION);
$file1 = $_FILES['proposal']['tmp_name'];
$size1 = $_FILES['proposal']['size'];
if (!in_array($extension1, ['zip', 'pdf', 'docx'])) {
    echo "You file extension must be .zip, .pdf or .docx";
} elseif ($_FILES['proposal']['size'] > 200000000) { // file shouldn't be larger than 200Megabyte
    echo "File too large!";
} else {
    if (move_uploaded_file($file1, $destination1)) {

    foreach($_POST['groupmem'] as $user){
        $filename2 = str_replace(" ", "_","{$user}.{$_FILES['proposal']['name']}");
        $destination2 = '../img/proposal/' . $filename2;
        if ($user <> $user1) {
            if (!copy($destination1, $destination2))  echo "failed to copy $file...\n";
        }

        $sql = "UPDATE project SET proposal_name='$filename2' WHERE u_id='{$user}' ";
        if (mysqli_query($conn, $sql)) {
        echo "File uploaded successfully";
        }
    }

    } else {
        echo "Failed to upload file.";
    }

}
