Different regular expression match result in PHP 7.4.11 and 7.4.12
ken678 replied to ken678's topic in Regex Help
Thank you for the explanation requinix. I will rework the expression but I'm working on legacy code and the expression is significantly more complicated than the above so just hoping not to break anything! -

I'm hoping someone might be able to explain to me why the following code produces different results in PHP 7.4.11 and 7.4.12. This is a simplified version of a real example from a project I'm working on. I can see that 7.4.12 moved to PCRE 10.35 but can't see any obvious reason why the below would behave differently. <?php preg_match('/([^\.]|^)\s*a/', "a", $matches); var_dump($matches); https://onlinephp.io/c/b56ca
