What is the significance of multipart/byterange in the context of PHP uploads and how can it be utilized effectively?

The significance of multipart/byterange in the context of PHP uploads is that it allows for the uploading of large files in smaller chunks, which can help prevent timeouts and memory issues. This can be especially useful when handling uploads of large files in PHP. 

// Set the content type to multipart/byterange
header('Content-Type: multipart/byterange');

// Process the uploaded file in chunks
$chunkSize = 1024 * 1024; // 1MB chunk size
$bytesUploaded = 0;

$targetFile = 'uploads/' . basename($_FILES['file']['name']);

$handle = fopen($_FILES['file']['tmp_name'], 'rb');
while (!feof($handle)) {
    $chunk = fread($handle, $chunkSize);
    file_put_contents($targetFile, $chunk, FILE_APPEND);
    $bytesUploaded += strlen($chunk);
}
fclose($handle);

echo 'File uploaded successfully!';
