If you are downloading files, search for "php curl multithreading" or see [[http://www.lijingquan.net/php-mtidown.html | a multi-threaded PHP download class online]?

If you just get interface data, look at [[http://blog.longwin.com.tw/2009/10/php-multi-thread-curl-2009/ | PHP uses CURL to synchronously crawl multiple Web pages] and the final reference of the article
