Has Substring
Lab: PHP String Building and Processing Basics
Video Runtime: 21:47
There are times when you check if a substring exists within a string. For example, maybe you want to check for a class attribute or if the read more link text says “Continue reading.” PHP gives you do this using strpos
.
This PHP instruction checks for the substring or character (needle) that you want within the target string (haystack). If it finds it, then it returns its character position to you; else, it returns false
.
In this episode, you will search the content as well as the read more link. I’ll show you how it works and when to use it.
Who needs copy/paste? Right. Writing code from scratch is fun!
