To define a function in PHP, you would use the following syntax:

```php
function functionName(parameters) {
// function body
}
```

Here's a step-by-step breakdown:

1. Start with the keyword `function`. This tells PHP that you're defining a function.

2. Next, provide a name for your function using `functionName`. This should be something descriptive that tells you what the function does. Function names are case-insensitive.

3. After the function name, include any parameters that the function needs inside parentheses `()`. If there are multiple parameters, separate them with commas.

4. Then, enclose the body of the function — the code that gets executed when the function is called — in curly braces `{}`.

5. Inside the function body, you can refer to the parameters as if they were variables.

Here's an example of a simple PHP function that adds two numbers:

```php
function addNumbers($num1, $num2) {
return $num1 + $num2;
}
```

In this example, `addNumbers
