PHP uses curl to download remote HTML files

It is said that using curl when downloading remote HTML files is a bit more efficient than file_get_contents. $ch = Curl_init (); curl_setopt ($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); The information obtained by CURL_EXEC () is returned as a file stream, rather than as a direct output. If not added, even without echo, it will automatically output $content = curl_exec ($ch); Perform Curl_close ($ch); Shut down Echo $content; Copy Code
