PHP uses CURL to download remote HTML files

It is said that using Curl is more efficient than file_get_contents when downloading remote HTML files.                                                                                                                       
                                                                                                                                                                                                                                                                                                       



$ch = curl_init();

//Set UA
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//Convert the information obtained by curl_exec() Return as a file stream rather than output directly. If not added, even if there is no echo, it will automatically output
$content = curl_exec($ch);
//Execute
curl_close($ch);
//Close
echo $content;
