cronjob. run php only in a specified interval of time

I have set up a cronjob that excutes a php script every 35 minutes. The issue is that I only want it to run from 11 AM to 2 AM the next day. I want this to be automatic without having to add # manually to the crontab.

I've tried putting something like this at the top of the php script :

$time = date(H);

if ($time < 23 & $time > 11)
{
   echo 'Working';
}
else
{
   echo 'Stopped';
}

But as you can see that only works on the same day.

NOTE The server is using another time zone which has +4 hours of difference with mine.

That means: 11 AM local time is 3 PM server time and 3 AM next day local means 7 AM next day server.

Let's take your code and apply some arithmetic, just substract 2 hours and you will have 9 to 23 instead of 11 to 23 + 0 to 2.

$time = date(H)  - 2 ;

if ($time < 23 & $time > 9 )
{
   echo 'Working';
}
else
{
   echo 'Stopped';
}

Try!

I guess your timezone is GMT-4, so 11 am to 2 am on your timezone will be 15 am to 6 am on the server; the other posible setup is you're talking on server time, which mean 11 am to 2 am is 7 am to 10 pm on your setup.

This mean it's possible you must adjust the code to substract 6 hours instead of 2.

shift the times to the correct timezone before checking.

You need to enclose H with quote marks:

$time = date("H");

Another way it is treated as constant, and, as you don't have such constant, date() receives empty argument

P.S. hohner provided better solution for you

So you want your cronjob to run between certain hours of the day? Have you tried:

35 11-23,0-2 * * * php /path/to/your/script.php

This will execute at 35 mins past every hour between 11am (day 1) and 2am (day 2) - everything is in server time.
