I have to run a php function for around 10 minutes. Now I am sheduling the job as a wp-cron-job. But it is getting timed out after 30seconds which is the maximum execution time for php. How to get rid of this timeout issue?
In my opinion function that works 10min is not a best idea. Can You maybe refactor Your function or simply try to build
My favorite article about that: https://pippinsplugins.com/batch-processing-for-big-data/
30 seconds should be enough for a script in the web, but that's generally speaking.
Running your cron as php-cli will have no timeout limit, you can read more about this here
You can also increase the timeout in any php script, as discussed here - https://stackoverflow.com/questions/3829403/how-to-increase-the-execution-timeout-in-php already.
Here is also ready-made class for you to extend and batch process elegantly - https://github.com/gdarko/wp-batch-processing
I used it to run a big batch process on customers, and it's working great.
Here is an article about it
