我可以做一个CRON工作一个小时吗

Question

I am creating an app that requires a CRON job to be executed every 60 seconds.

My host only allows a CRON job once an hour.

I was wondering if I could create a script like this:

$i = 0;
while(1==1){
// update database code

delay(10000);

// $i is incremented once a minute/10000ms
$i++;
}

//if $i reaches 60 we know that the CRON has run for an hour
if($i == 60){
die();
}

Is this recommended? Will this accurately update my database every 60 seconds?

I don't mind if the script will be a few seconds out.

I understand I will need to set my php.ini to increase the max execution time.

Answer 1

Should work, if the hosting allows overriding of max_execution_time . You can do it right in the script, by the way: ini_set('max_execution_time', 0) . And be careful with memory. It's not C/C++, of course, but still a good idea to watch variables initialization and loops.
