Ensuring a Secure PHP File Upload

Check MIME types and ensure proper validation during file uploads for security.

Source Code

if (isset($_FILES['file'])) {
    $fileTmpPath = $_FILES['file']['tmp_name'];
    $fileType = $_FILES['file']['type'];
    
    if ($fileType == 'image/jpeg' || $fileType == 'image/png') {
        // Proceed with your file upload logic
        echo "File type is acceptable for upload.";
    } else {
        echo "File type not allowed.";
    }
}
