What is the significance of setting "name="images[]" in the HTML form for file uploads in PHP?

Setting "name='images[]'" in the HTML form for file uploads in PHP allows multiple files to be uploaded simultaneously. This is achieved by using an array in the form input name, which PHP can then process as an array of files. This is particularly useful when creating a form for uploading multiple images or files at once. 

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="images[]" multiple>
    <input type="submit" value="Upload">
</form>
