In that case put the timing loop INSIDE dothisfunction() and rather than
breaking out of the loop, execute a return to the calling script.

----------------
Thanks guys
sorry about the delay .. I am in Australia..
checking the time each loop would only work if the loops complete correctly
.. if the process locks mid loop php wont reach the criterion break because
it deals with each command linearly. ie
for (x=0;x!="array full";x++)
dothisfunction(x);
if ( (0 === ($x % 1000)) && (time () - $start_time) > $timeout)
break;
etc
if dothisfunction() locks up wont the entire script freeze?
maybe I am wrong..
what I am after is something like alert() in Perl or the 'on error resume
next' in ASP which runs externally to the loop and breaks to the next
instance if it is taking too long...
any ideas?
cheers!
