To elaborate on m0nty's excellent recommendation, PHPMyAdmin imposes limits on uploading/importing SQL files from your PC - a timeout (300 seconds) and a filesize (2 Mb, or sometimes less, depending on the host).
BigDump circumvents these limits. You simply FTP the SQL file to a folder on your web server along with the 'bigdump.php' script. Running the script via a web browser connects to your MySQL database and imports the file.
