The problem is that the script works on different hostings. What could be the problem?

Question

PHP

There is a script that parses the site, taking the information using regular expressions. Used by CURL.
It works on Ru-center hosting, but not on reg.ru. Could there be a problem in php.ini? I configured this file on 1st and 2nd server, setting the same maximums for requests, etc., but it still does not work.
It feels like some kind of timeout is going on, but where to change its value?

Answer 1

1. php version
2. CURL version
3. php.ini and its settings
4. Hosting restrictions on the load, after which processes are simply chopped.
Could you be more specific about the error.
