In PHP, you can declare a variable using the dollar sign symbol followed by the variable name. Here's an example:

$myVariable = "Hello World";

In this example, $myVariable is the name of the variable, and "Hello World" is its value.

You can also declare a variable without assigning a value to it:

$myVariable;

This will create an empty variable named $myVariable.

Note that in PHP, variable names are case-sensitive, which means that $myVariable and $MyVariable are two different variables. Also, PHP uses a dynamic type system, which means that you don't need to specify the data type of a variable when you declare it. The data type of a variable is determined by the value assigned to it.
