Join Kevin Skoglund for an in-depth discussion in this video Else and elseif statements, part of PHP Essential Training.
- [Instructor] In the last movie,…we saw the basics of an if statement,…and how we can have a section of code…that only executes if an expression evaluates to true.…In this movie, we're going to build on that…by talking about Else and Elseif,…that is the ability to have an alternative…that gets executed if something is not true.…Let's take a look.…So if we have if a is greater than b,…we want to echo a is larger than b,…we can use else immediately after it…to say if that's not true,…then the alternative version should be…to echo this section of code,…the statement, echo a is not larger than b.…
So one of these two things will be true.…We've basically divided the path into two…and said, if this is true, do the first statement,…else, do the second statement.…Now, again, this is without the curly braces,…which is suitable if you have only a single line of code,…but I'm going to strongly encourage you…even if you have a single line of code…to always use curly braces,…and if you have multi-line code,…you'll definitely want to use them.…
