Your next challenge is to figure out how to check for a character or substring in a given haystack (source string). Just like with the “starts with” functionality, there are a couple of different implementations. In this two-part series, you’ll explore:
- Implementation #1: Using a string position implementation
mb_strposby leveraging the offset argument to start exactly where we want.
- Implementation #2: Use the same strategy as we did with “starts with”.
We’ll walk through both implementations, talk about how they work and process, and then explore which is the better solution and why.
Your best friend is code, Tonya is making the introductions.
