The **boolean data type** (`bool`) is used to represent **logical values**. A boolean variable can only have two possible values: **true** or **false**. Booleans are fundamental for **decision-making** and **conditional operations** within PHP programs.

## Outputting Boolean Values 
___

You can output boolean values (`true` or `false`) using the `echo` function. When you use `echo` with `true`, PHP automatically outputs `"1"`, as `true` converts to this string:

When you use `echo` with `false`, nothing is output, as `false` converts to an empty string:

This approach allows for convenient output of boolean values without manually converting them to strings.
