Proposal for a new basic function: str_contains

Hello PHP Devs, I would like to propose the new basic function: str_contains. The goal of this proposal is to standardize on a function, to check weather or not a string is contained in another string, which has a very common use-case in almost every PHP project. PHP Frameworks like Laravel create helper functions for this behavior because it is so ubiquitous. There are currently a couple of approaches to create such a behavior, most commonly: <?php strpos($haystack, $needle) !== false; strstr($haystack, $needle) !== false; preg_match('/' . $needle . '/', $haystack) != 0; All of these functions serve the same purpose but are either not intuitive, easy to get wrong (especially with the !== comparison) or hard to remember for new PHP developers. The proposed signature for this function follows the conventions of other signatures of string functions and should look like this: str_contains(string $haystack, string $needle): bool This function is very easy to implement, has no side effects or backward compatibility issues. I've implemented this feature and created a pull request on GitHub ( Link: https://github.com/php/php-src/pull/5179 ). To get this function into the PHP core, I will open up an RFC for this. But first, I would like to get your opinions and consensus on this proposal. What are your opinions on this proposal? Kind regards, Philipp Tanlak
