fsockopen to curl problem..

[btray77]

I have the original code of:

 

if (@fsockopen($_SERVER['SERVER_NAME'], $c[1], $errno, $errstr, $portcheck))

 

I'm wanting to convert that to use CURL.

 

I've tried the following with no luck.  What am I doing wrong?

 

$cx = curl_init($_SERVER['SERVER_NAME']);

curl_setopt($cx, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($cx,curlOPT_port,$c[1]);

curl_setopt($cx, CURLOPT_FAILONERROR,true);

curl_setopt($cx, CURLOPT_TIMEOUT, $portcheck);

$temp = curl_exec($cx);

if (!curl_errno($cx))

 

There are some ports that should give an error and some that should not.  The code it to tell me if the port is giving error or not.  (aka is DNS/POP3/SMTP/ETC server up/down)

 

 

 

Also second part question.  What would I have to do to test to see if I could use fsockopen or if I need to use curl.

 

 

Thank you

if you are connecting to ports other than http or https then shouldn't you stick to fsockopen

some servers do not allow you to use fsockopen...  Like dreamhost...

i don't think this would work because curl will send an http request to a working POP server then say there is an error because POP did not respond like a HTTP server so there for the script would say the service is down you could try using stream_socket_server()

$sock = stream_socket_server("tcp://{$_SERVER['SERVER_NAME']}:{$c[1]}");
stream_set_timeout($sock,$portcheck);
if($sock){
//port ok
}else{
//port error
}

not exactly sure but that should work although it might wait 30 seconds because of when the timeout is set
