does PHP support something like ampersand in bash (forking)? Let's say I wanted to use cURL on 2 web pages concurrently, so script doesn't have to wait before first cURL command finnishes, how could one achieve that in PHP? Something like this in bash:
curl www.google.com &
curl www.yahoo.com &
wait

No. See the other answers, though I do point out that the PCNTL extension is UNIX only.

cURL supports running multiple downloads concurrently.
