Hi there,
having a short look on the php site ( http://de2.php.net/manual/de/function.curl-init.php ),
the following might fit your needs...
It will return the retrieved bytes if everything goes well and FALSE if it doesn't

return ($res) ;

Here is what I use, modified slightly to return FALSE if it fails. Check the TIMEOUT to see if that is OK for your needs.

Hi @ray, thanks for the great script.
In the end of your script I put this lines:
//////////////////////////
$vision = my_curl("http://www.google.pt/search?q=free+photos&hl=pt-PT&start=10&sa=N");
echo $vision;
//////////////////////////
I execute the script and in browser appear entire site http://www.google.pt/search?q=free+photos&hl=pt-PT&start=10&sa=N
For this example I don't want the site, but just if each site have connection (try for one or two seconds).
I like your script but I need to adapt to my necessity, so I need something like this:
If ($html == true){
Connect
} else {
No connect
}
How I do that?
Regards, JC

Hi again @ray, I put in this way for check the connection:
if(my_curl("http://www.google.pt/search?q=free+photos&hl=pt-PT&start=10&sa=N")) {
echo "Yes!";
} else {
echo "No.";
}
Do you thing this is the best way?
What this line do "curl_setopt($curl, CURLOPT_TIMEOUT, 10);"?

To just return True or False, try this.
The cURL options are documented here:
http://us.php.net/manual/en/function.curl-setopt.php
The CURLOPT_TIMEOUT is the maximum number of seconds to allow cURL functions to execute.
Best regards, ~Ray

Hi @ray, just one thing:
What is correct:
if (!$html = curl_exec($curl)) { $html = FALSE; } OR
if (!$html == curl_exec($curl)) { $html = FALSE; }

The single equal sign is correct but I see an error in my example. Corrected copy posted below.
This single-equal construct says, "run curl_exec and assign the output to $html, then test $html and if it is FALSE, it satisfies the 'if' statement."
