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!
