PHP带有响应的异步HTTP请求

Question

I need to make about 10 requests in my script, and combine their responses. However, if I do it by calling get_file_contents 10 times, it works much slower than for example calling $.json 10 times in Javascript. I tried looking for ways to make asynchronous http requests in PHP, but every single piece of information I found started with "I don't need the response", which is not my case.

Answer 1

file_get_contents is a synchronous function, so when you call it 10 times, you call it 10 times sequentially. You need to make requests in parallel. curl_multi_* methods family is probably what you are looking for. If you are not familiar with curl enough it may be tricky to implement it correctly, so I'd recommend you to use some library for that.

You can take a look at this library https://github.com/petewarden/ParallelCurl
