How to use CURL via a proxy?

Here is a working version with your bugs removed.

$url = 'http://dynupdate.no-ip.com/ip.php';$proxy = '127.0.0.1:8888';//$proxyauth = 'user:password';$ch = curl_init();curl_setopt($ch, CURLOPT_URL,$url);curl_setopt($ch, CURLOPT_PROXY, $proxy);//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_HEADER, 1);$curl_scraped_page = curl_exec($ch);curl_close($ch);echo $curl_scraped_page;

I have added CURLOPT_PROXYUSERPWD in case any of your proxies require a user name and password.I set CURLOPT_RETURNTRANSFER to 1, so that the data will be returned to $curl_scraped_page variable.

I removed a second extra curl_exec($ch); which would stop the variable being returned.I consolidated your proxy IP and port into one setting.

I also removed CURLOPT_HTTPPROXYTUNNEL and CURLOPT_CUSTOMREQUEST as it was the default.

If you don't want the headers returned, comment out CURLOPT_HEADER.

To disable the proxy simply set it to null.

curl_setopt($ch, CURLOPT_PROXY, null);

Any questions feel free to ask, I work with cURL every day.

I have explained use of various CURL options required for CURL PROXY.

$url = 'http://dynupdate.no-ip.com/ip.php';$proxy = '127.0.0.1:8888';$proxyauth = 'user:password';$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL callcurl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with portcurl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and passwordcurl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY typecurl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0$curl_scraped_page = curl_exec($ch);curl_close($ch);echo $curl_scraped_page;

Post declaring the proxy settings in the php script file issue has been fixed.

$proxy = '10.172.123.1:80';curl_setopt($cSession, CURLOPT_PROXY, $proxy); // PROXY details with port
