yet another curl question....

Jenski · 06-26-2008, 09:43 AM

ok, I have this code:

Code:

$ch = curl_init('http://www.google.co.uk'); // the target
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return the page
$result = curl_exec($ch); // executing the cURL
curl_close($ch); // Closing connection
echo $result;

Which I got from here:
TalkPHP - cURL Basics

Any ideas why I would end up with a blank screen? with no errors?
Do I need to configure something with the curl library or something?
I'm using php 5
Thanks
Jen

Do you normally see errors on your development server? I imagine it is causing errors, but you're not displaying them, and possibly logging them. You need to enable the cURL module in order for it to work.

First you may wish to enable the displaying of errors. Find the following 2 lines and change them to what they are below. Those are the only 2 lines, or so I think.

Code:

error_reporting  =  E_ALL
display_errors = On

And then to enable cURL, acquire the DLL/SO (depending on OS) from PHP.net, and last of all uncomment the following line, again in php.ini:

Code:

extension=php_curl.dll

Thanks for your reply. I've double checked the php.ini file and it is already loading the curl extention, I have also enabled logging, and still comes up with a blank screen.
It obviously recognises the curl function, just acts as if it doesnt know what to do with it.

Try adding a trailing slash after the url. Curl acts funny with some server setups.

PHP Code:


			
$ch = curl_init('http://www.google.co.uk/'); // the target
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return the page
$result = curl_exec($ch); // executing the cURL
curl_close($ch); // Closing connection
echo $result;

still no avail

is there another setting in the php ini file that could be preventing it? Safe Mode or something?

I just tried

Code:

$exists = function_exists  ('curl_init');
echo $exists;

and it returns '1'.
I'm running out of ideas...

Also when I do phpinfo();
it comes up with:

Code:

curl
cURL support 	        enabled
cURL Information 	libcurl/7.18.0 OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.1

I don't know what's stopping it

HA! FOUND IT!!!!!

I didn't configure our networks Proxy Server in the options!!

If anybody else has this problem here is the solution:

Code:

$proxy="<proxy_ip>:<proxy_port_no>";
$ch = curl_init('http://www.google.co.uk/'); // the target
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return the page
$result = curl_exec($ch); // executing the cURL
curl_close($ch); // Closing connection
echo $result;

Hope this helps somebody
