How to convert php array into function parameters

When we need to pass a PHP array to a function as a parameter, there is a very convenient way, which is to use the splat operator (also called the spread operator).

Use the splat operator to pass each element in the array to the function as an independent parameter. Here is an example:

function myFunction($param1, $param2, $param3) {
  // function code here
}

$myArray = array('a', 'b', 'c');
myFunction(...$myArray);

In the above example, we define a function named myFunction, which contains three parameters $param1, $param2 and $param3. Then, we created an array called $myArray with 3 elements: a, b, and c. Finally, we pass $myArray to the myFunction function and add 3 dots in front to convert it into a function parameter using the splat operator.

Inside the function, the value of $param1 is 'a', the value of $param2 is 'b', and the value of $param3 is 'c'.

Using the splat operator, you can also combine multiple arrays into a parameter list and pass it to the function. For example:

function myFunction($param1, $param2, $param3) {
  // function code here
}

$myArray1 = array('a', 'b');
$myArray2 = array('c', 'd');
$myArray3 = array('e', 'f');

myFunction(...$myArray1, ...$myArray2, ...$myArray3);

In this example, we define three arrays $myArray1, $myArray2 and $myArray3, each array contains 2 elements. We then pass these arrays to the myFunction function and use the splat operator to convert them into function parameter lists.

Inside the function, the value of $param1 is 'a', the value of $param2 is 'b', the value of $param3 is 'c', the value of $param4 is 'd', and the value of $param5 is 'e', ​​the value of $param6 is 'f'.

In short, using the splat operator to convert PHP arrays into function parameters is a very convenient method. It can make the code cleaner and more readable, while reducing some manual coding work.
