What are the best practices for handling file uploads in PHP forms with multiple file inputs?

When handling file uploads in PHP forms with multiple file inputs, it is essential to loop through each file input and process them individually. This ensures that each file is properly validated, uploaded, and saved to the desired location. By using a loop, you can efficiently handle multiple file uploads without duplicating code. 

// Loop through each file input
foreach($_FILES['file_inputs']['name'] as $key => $value){
    $file_name = $_FILES['file_inputs']['name'][$key];
    $file_tmp = $_FILES['file_inputs']['tmp_name'][$key];
    $file_type = $_FILES['file_inputs']['type'][$key];
    $file_size = $_FILES['file_inputs']['size'][$key];
    
    // Validate file type, size, and other constraints
    // Process file upload and save to desired location
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
}
