…One of the most important features of the programming language like PHP is the…use of variables to store values that might change or aren't known in advance.…If you've done any work with Javascript much of this…will be familiar to you but there are some important differences.…Even if you don't know any other programming language…You use variables all the time, without even realizing it.…For example, what's your name? My name's David,…but my producer's name is Scott. The word name is a real-life variable.…
Name always remains the same, but its value changes.…Let's look at some other real-life examples of variables.…What day is it?…What's the distance? Which city are you going to?…To convert these real-life variables into PHP variables, just…stick a dollar sign at the beginning of the word.…A PHP…script can then change the value of the variable, depending on…who's logged into a website, name might become David, Scott, or Linda.…
PHP is capable of working out the current day or date.…So day might become Monday, Tuesday, Wednesday, and so on.…
