PHP Multiple Curl Requests
提问by Simon
I'm currently using Curl for PHP a lot. It takes a lot of time to get results of about 100 pages each time. For every request i'm using code like this
我目前在 PHP 中使用 Curl 很多。每次得到大约100页的结果需要花费大量时间。对于每个请求，我都使用这样的代码
$ch = curl_init();
// get source
curl_close($ch);
What are my options to speed things up?
我有哪些选项可以加快速度？
How should I use the multi_init()etc?
我应该如何使用multi_init()等？
回答by Emil Vikstr?m
- Reuse the same cURL handler ($ch) without running curl_close. This will speed it up just a little bit.
- Use curl_multi_initto run the processes in parallel. This can have a tremendous effect.
- 在不运行 curl_close 的情况下重用相同的 cURL 处理程序 ($ch)。这将加快一点点。
- 使用curl_multi_init并行运行进程。这会产生巨大的影响。

take curl_multi - it is far better. Save the handshakes - they are not needed every time!
采取 curl_multi - 它要好得多。保存握手 - 不是每次都需要握手！

when i use code given in "http://php.net/curl_multi_init", response of 2 requests are conflicting. But the code written in below link, returns each response separately (in array format) https://stackoverflow.com/a/21362749/3177302
当我使用“ http://php.net/curl_multi_init”中给出的代码时，2 个请求的响应发生冲突。但是下面链接中编写的代码，分别返回每个响应（以数组格式） https://stackoverflow.com/a/21362749/3177302

or take pcntl_fork, forksome new threads to execute curl_exec. But it's not as good as curl_multi.
或采取pcntl_fork，fork一些新的线程来执行curl_exec。但它不如curl_multi.
