PHP Multiple Curl Requests

问题

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

$ch = curl_init();

// get source

curl_close($ch);

What are my options to speed things up?

How should I use the multi_init() etc?

回答1:

• Reuse the same cURL handler ($ch) without running curl_close. This will speed it up just a little bit.
• Use curl_multi_init to run the processes in parallel. This can have a tremendous effect.

回答2:

take curl_multi - it is far better. Save the handshakes - they are not needed every time!

回答3:

or take pcntl_fork, fork some new threads to execute curl_exec. But it's not as good as curl_multi.

回答4:

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
