What is the significance of using the array name "fileToUpload[]" in the HTML form for multiple file uploads in PHP?

When uploading multiple files in PHP, using the array name "fileToUpload[]" in the HTML form allows you to handle multiple file uploads simultaneously. This naming convention tells PHP to treat the file input as an array, allowing you to loop through each uploaded file and process them individually. This is especially useful when dealing with forms that allow users to upload multiple files at once. 

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