PHP卷曲的性能相关问题是什么？

Question

My client wants to extract the html content of a live webpage and make a copy of the html page in his server. I am thinking of using curl and is there any performance issue linked when I am intending to use curl? Will it use a lot of server memory.

If PHP curl has a performance issue, what is the best alternative to do this?

I am intending to download the page when a user submits the web URl in a form. The server that I am hosting the web is in a linux platform.

Thank you in advance!

Answer 1

I'd use wget instead for a quick and dirty solution (on linux)

wget -r 

Please don't mention performance when you're using PHP. If you want to start asking those questions, perhaps you should be looking into network programming. As someone who likes playing with network programming, I should warn you that it's not a trivial topic.
