Hi everyone, I stumbled across the following issue, proposing to add a way to validate regex. [1]
There is currently no way of knowing if a regex pattern is valid, apart from writing clunky code. [2] Two propositions emerged from the issue: either create a dedicated "preg_validate()" function, or add a new flag to "filter_var()", namely FILTER_VALIDATE_REGEX_PATTERN. I would be in favor of the latter. The approach and implementation would surely be simpler. I don't feel like we should do advanced error management. Knowing if a pattern is valid or not would suffice for the vast majority of cases. I don't think the second approach would require an RFC. Christoph thinks that this should at least be announced on the mailing list, so here we are. Looking forward to your feedback. — Alexandre Daubois [1] https://github.com/php/php-src/issues/9289 [2] https://stackoverflow.com/questions/4440626/how-can-i-validate-regex
