PHP uses CURL to download remote HTML files

It is said that Curl is more efficient than file_get_contents in downloading remote HTML files. $ Ch = curl_init (); Curl_setopt ($ ch, CURLOPT_URL, $ url ); // Set the URL, which can be placed in the curl_init parameter Curl_setopt ($ ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1 "); // Set UA Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 ); // Return the information obtained by curl_exec () in the form of a file stream instead of directly outputting it. If no echo is added, the output is automatically generated even if no echo exists. $ Content = curl_exec ($ ch ); // Execute Curl_close ($ ch ); // Close Echo $ content;
