Can preg_match break if the string is too long?

Question

PHP

Hello, I have a very simple regex
preg_match('/^(\d+,?)+$/', $myStr);
Problem: The
regex should check if the string matches the format - number (1 or more) comma (0 or 1)
Everything works as intended until the length of the string goes beyond a certain value
In my case, the string consists of 22 and you with symbols
