I am unable to make a php curl request with port number , without port number i am getting response properly. Through terminal when i do curl http://www.sample.com:8088 i am getting response back properly. But not through php curl on doing curl_inf() i am getting ``` Array ( [url] => http://www.sample.com:8088/ [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => 0 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0 [namelookup_time] => 0 [connect_time] => 0 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 [certinfo] => Array ( ) ) ``` My code ``` $url = "http://www.sample.com:8088/"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_TIMEOUT, 400); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, True); curl_setopt($ch, CURLOPT_RETURNTRANSFER, True); $report=curl_getinfo($ch); print_r($report); $result = curl_exec($ch); curl_close($ch); echo $result; ``` this code give me response from ubuntu , but not giving response from cent os if port number is specified.
