What are some common pitfalls when using cURL for file uploads in PHP?

One common pitfall when using cURL for file uploads in PHP is not setting the correct Content-Type header for the file being uploaded. This can result in the file not being uploaded correctly or the server rejecting the upload. To solve this issue, make sure to set the Content-Type header to match the file type being uploaded. 

// Set the correct Content-Type header for the file being uploaded
$file_path = '/path/to/file.jpg';
$file_mime = mime_content_type($file_path);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
    'file' => new CURLFile($file_path, $file_mime, basename($file_path))
]);
curl_exec($ch);
curl_close($ch);
