减少 cURL PHP 中的带宽使用

Question

I'm using basic cURL requests to fetch webpages in PHP, however these webpages are big in size and I'm limited in bandwidth usage.

Is there a way to reduce/optimize cURL data usage, for example using compression. I also heard that Brotli compression is the best, but I'm not sure how to use it.

Answer 1

$headers[] = "Accept-Encoding: gzip"; // tell the server you accept gzip
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch,CURLOPT_ENCODING , "gzip"); // tells curl to gunzip it automatically
$data = curl_exec($ch);

Not tried this with brotli, support will vary by software version which you didn't tell us about.
