Php curl_init function usage

First, in php. ini in C \ windows, I opened the extension = php_curl.dll function, and then restarted apapche. The following is what I wrote to capture PHP information in Baidu:

2. // Initialize curl
3. $ Ch = curl_init () or die (curl_error ());
4. Echo "test ";
5. // Set URL parameters
6. Curl_setopt ($ ch, CURLOPT_URL, "http://www.baidu.com/s? Wd = php ");
7. // Request that CURL return data
8. Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
9. // Execute the request
10. $ Result = curl_exec ($ ch) or die (curl_error ());
11. // Obtain the returned result and display it
12. Echo $ result;
13. Echo curl_error ($ ch );
14. // Disable CURL
15. Curl_close ($ ch );
16. ?>

But why didn't we respond? No text for the test. if I put echo "test" on the first line, the output will be available. I guess the curl_init () function is not running yet!

Check whether CURL extension support is available in PHP phpinfo! Copy php_curl.dll to c: \ windows \ and c: \ windows \ system32, restart apache, and try again. instead of the php_curl.dll file, copy libeay32.dll and ssleay32.dll in the php directory to c: restart apache in \ windows \ system32.
