Does file_get_contents() use a cache?

Question

If I write:

 $mypage=file_get_contents("www.mywebsite.com/mypage.htm");

The first time I run the script, file_get_contents() will surely make a HTTP request to www.mywebsite.com for mypage.htm, and get a response with the content of mypage.htm.

But every next time I run the script, will file_get_contents() get the real file on www.mywebsite.com? Or it has some kind of cache on the localhost?

No it doesn't but you might use db, apc or memcached to handle the cache yourself. — Anze Jarni, Jul 29 '12 at 10:14

It does not. However, there will be a speed-up because the DNS resolution step may be faster on subsequent tries (till the cached entry expires), as the DNS records are cached by the server's OS.
