wecenter—enable CURL extension to allow the server to support remote collection of PHP curl functions

curl(), file_get_contents(), and snoopy.class.php are three tools used in remote page crawling or collection.

I still prefer to use snoopy.class.php because it is more efficient and No server-specific configuration support is required, and it can be used in ordinary virtual hosts;

file_get_contents() is slightly less efficient, and in common failure situations, curl() is very efficient and supports multi-threading, but the curl extension needs to be turned on.

The following are the steps to enable the curl extension:
　1. Copy the three files php_curl.dll, libeay32.dll, and ssleay32.dll under the PHP folder to system32;
　2. Remove the semicolon in extension=php_curl.dll in php.ini (c:WINDOWS directory);
　3. Restart apache or IIS.

The above introduces wecenter-enable CURL extension, so that the server supports remote collection of PHP curl function, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
