Hi,

I've had a search through google but couldn't really find the answer I was
looking for.I'm
new to PHP, so please take it <relatively> easy.

I've created a script which runs some SNMP queries. I'd like help if
possible in formatting one of the
values it returns.

When you run a query for the system uptime the result is displayed like so:

Timeticks: (4592345) 12:45:23.45

1.) I would like to remove the first two "fields" so I am left with:
12:45:23.45

I have managed to remove the Timeticks: part but don't know how to remove
the (4592345) (because this is of variable size).

$sysuptime = eregi_replace("Timeticks: ","",$sysuptime);

I don't know if it is possible but could you say remove everything within
the brackets - is that possible in a regular expression?
$sysuptime = eregi_replace("[()]","",$sysuptime); ???? (I tried that and it
didn't work ;) )

2.) If possible I would like to convert the output 12:45:23.45 to something
more like 12hr 45 mins

Obviously as the uptime increases that needs to incorporate _days_ as well.

3. Is it good/bad practice to use the same variable name twice in the
statement above?

Many thanks

David
