PHP: fopen() and fread()

programming
1

hi,

in my application there is a code block that looks something like this:


$fp = fopen($rssURL,"r") 
 
while ($data = fread($fp, 4096))
{
	//process data
}

the $rssURL is the location of an rss file on some website’s server.

so my question is: when does fopen() and/or fread() time out? is there any way to detect this? i don’t want my script to sit there for hours trying to open one 2K file? can i set the limit?

thanks
