Copy code The code is as follows:

 
$cookie_jar = tempnam('./tmp','cookie' ); 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL,'Login address'); 
curl_setopt($ch, CURLOPT_POST, 1); 
$request = 'username= xxx&pwd=xxx'; 
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);//Transfer data
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);//Save the returned cookie information in the $cookie_jar file Medium
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//Set whether the returned data is automatically displayed
curl_setopt($ch, CURLOPT_HEADER, false);//Set whether to display the header information
curl_setopt( $ch, CURLOPT_NOBODY, false);//Set whether to output page content 
curl_exec($ch); 
curl_close($ch); //get data after login 

$ch2 = curl_init (); 
curl_setopt($ch2, CURLOPT_URL, 'View address'); 
curl_setopt($ch2, CURLOPT_HEADER, false); 
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt( $ch2, CURLOPT_COOKIEFILE, $cookie_jar); 
$orders = curl_exec($ch2); 

echo $orders; 
curl_close($ch2);// Practice has proven to be very stable:) 
?> 

Test on this machine first, remove the ; in front of extension=php_curl.dll in php.ini, check phpinfo(), there is no curl.
Check the documentation,

Copy the code The code is as follows:

 
Note to Win32 Users: In order to enable this module on a Windows environment, libeay32.dll and ssleay32.dll must be present in your PATH. 

Copy libeay32.dll and ssleay32.dll to system32, restart apache, refresh phpinfo(), Saw curl.

Copy code The code is as follows:

cURL Information libcurl/7.16.0 OpenSSL /0.9.8d zlib/1.2.3 

The local test passed successfully, and then tested on the server. Curl was not installed originally, so I had to recompile php.
Added --with-curl=/usr/local/curl after the original compilation parameters.
My configuration this time is:

Copy code The code is as follows:

 
./configure '--prefix= /usr/local/php5' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql=/usr/local/mysql' '--with-gd=/usr/local /gd' '--with-zlib' '--with-png' '--with-jpeg-dir=/usr/local/jpeg' '--with-freetype-dir=/usr/local/freetype' ' --enable-sockets' '--with-iconv' '--enable-mbstring' '--enable-track-vars' '--enable-force-cgi-redirect' '--with-config-file-path =/usr/local/php5/etc' --with-curl=/usr/local/curl 

OK soon. phpinfo displays
