wait some minutes

Anon

I have a webpage which is called each night and which loops through a whole lot of transactions (batch processing). Sometimes however, it might not be possible to start at the predefined time (script is called by a bot at 3 am). Is it possible to have a command in the script which lets it wait for a minute or two and then tries again?

Why not cron it a second time later. If there is no work to be done the second time it just exists.

could be, but what if it still doesn't have access? This is a script which absolutely has to be run every night, but which might have a problem to access certain files (if a user is busy...).

was thinking of a "for()" statement...

for (!$open = site_is_open()) {
$open = site_is_open();
}

what do you think?

Anon

How about this?

$start=time();
while (!site_is_open())
{
sleep(120); // wait 2 minutes to try again
if (time() - $start > 5*3600) // give up after 5 hours
break;
}

The if statement isn't strictly necessary, but I have an irrational fear of endless loops.

HTH,
