Variables are use to store the value
Creating PHP Variables
In PHP, a variable starts with the
$ sign, followed by the name of the variable:
<?php $txt = "Hello world!"; $x = 5; $y = 10.5; ?>
After the execution of the statements above, the variable
$txt will hold the value
Hello world!, the variable
$x will hold the value
5, and the variable
$y will hold the value
Note: When you assign a text value to a variable, put quotes around the value.
Note: Unlike other programming languages, PHP has no command for declaring a variable. It is created the moment you first assign a value to it.
