Join Kevin Skoglund for an in-depth discussion in this video Variables, part of PHP Essential Training.
- Our exploration of the PHP programming language…is going to begin with an exploration…of the different structures or types…that we can use while writing PHP,…and the first of those…that we're going to look at are variables.…Now, if you've done programming before,…then you're familiar with what a variable is,…but if you haven't let me start by explaining…that a variable is a symbolic representation of a value.…You can think of it as a symbol…that refers to something,…and that's going to make a lot more sense…once we actually start using them.…But, as its name suggests,…it can change over time, or vary.…It has a variable value,…because it can point to different values.…
Now in PHP, there are some rules about the kinds of names…that we can give to variables…They need to start with a dollar sign…that needs to be followed by…either a letter or an underscore.…They contain letters, numbers, underscores, or dashes.…They cannot contain any spaces,…and they are case sensitive.…It makes a difference whether we use an uppercase letter…
