The main assignment operator is ‘=’, which basically assigns a value on the right to a variable on the left. If you think this is the same as an equal sign in mathematics, don’t! Think of it as a ‘assigned to’ so whatever is on the right is assigned to the left.
Here’s a simple example:
There are various kinds of operators used in PHP, but we’re going to start with the most basic and commonly known operator - the Math operators.
What are operators? They are basically a special set of characters (or symbols, if you like) which tells PHP to perform a certain operation. For example, the ‘+’ (plus sign) is used for arithmetic adding of 2 values or variables.
Now you know why I’m starting with the Math operators, cos anyone who has had any basis schooling in Mathematics will be familiar with the Math operators.
In PHP, you can use something called a ‘variable‘ to store values or reference to things. It’s like a container which you can put some thing or things inside which can be easily passed around.
