[EMAIL PROTECTED]: That is what i am saying, this will never comes to next
iteration. If i wan't to do some kind of error check, it will never be
executed, because whole program will stop at file_get_contents() and
will not execute anything after this call. Thats the problem. This
function will never return anything.
With this timeout, this script have to print '#' at least once a
second.
But the default_socket_timeout stops waiting for connection but in this
case the file_gets_contents() is already downloading when server drops
the connection because of network unstability or service overload.
Isn't there some kind of timeout, that will stop waiting for broken
connection after specified time?

It won't matter what you put in timeout if you wrap everything in a
while(1) loop. Of course it just sits there, try adding some error
checking there..

[EMAIL PROTECTED]: It's possible, but in this case the
default_socket_timeout have to close the socket and continue with next
URL (crawler freezing too with many different URLs). Or
default_socket_timeout doesn't matter in here?
It's true, that my router sux, but i don't see any reason why PHP
should crash at first problem with connectivity, that ends in total
script freeze, i thought, that is why we have socket timeout option. Or
not?

Are you sure it's not just your network connection freezing? f.e. some
kind of firewall stopping you from connecting to one site too many times
in too short time? (fyi: your script works fine for me, I stopped it
after 10 minutes..)

I tryed to run this at PHP4 - CLI (MS Windows Server2003)
It returned this errors. May be, this error is handled another way in
PHP5 and it causes the hang up...
