Sensex Figure using a Linux Command

This one command will fetch and display the latest sensex figure in Linux. This command basically downloads a page, locates a specific line, and then extract just the necessary portion from it. I am sure you could find other uses for this method.

curl -s "http://money.rediff.com/money/jsp/markets_home.jsp" |grep ''|head -n1|perl -pe 's/^.+\">([\d\,\.]+)<\/TD>.+$/\1/i;'

Using PHP’s Curl functions behind a Proxy

Using PHP’s Curl functions even if the net is accessible only thru a proxy. This is the only way curl can be used if you use GoDaddy’s hosting.

ch = curl_init("http://rss.news.yahoo.com/rss/topstories");

curl_setopt(ch, CURLOPT_HEADER, false);
curl_setopt(ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt(ch, CURLOPT_PROXY, "");
curl_setopt(ch, CURLOPT_PROXYPORT, 80);
//curl_setopt (ch, CURLOPT_PROXYUSERPWD, "username:password");

data = curl_exec (ch);
