Q:

sorting - PHP- combining two params within match() expression to be set dynamically

Hello everyone,

I have been working on a sorting function in PHP, and I have encountered a challenge. I am using the `match()` expression to sort my data based on different parameters. However, I want to combine two parameters within the `match()` expression, and I need it to be set dynamically.

For example, let's say I have two variables: `$param1` and `$param2`. I want to sort my data based on the combination of these two variables within the `match()` expression. I have tried something like this:

```php
$sortedData = match(true) {
$param1 && $param2 => 'Sort condition 1',
$param1 || $param2 => 'Sort condition 2',
default => 'Sort condition 3',
};
```

However, this doesn't seem to be working as expected. It's not considering the combination of `$param1` and `$param2` within the `match()` expression.

Is there a way to achieve what I am trying to do? Can I dynamically combine two variables within the `match()` expression to sort my data based on their combined values?

Any help or suggestions would be highly appreciated. Thank you in advance!

Hey there!

I've faced a similar issue before while working with the `match()` expression in PHP. To dynamically combine two parameters within the `match()` expression, you can use the `match(true)` condition and utilize the `&&` operator.

In your case, instead of directly using `$param1 && $param2` as a condition within the `match()` expression, you can use them as separate conditions and combine them dynamically using the `&&` operator. Here's an example:

php
$sortedData = match (true) {
($param1 && $param2) => 'Sort condition 1',
($param1 || $param2) => 'Sort condition 2',
default => 'Sort condition 3',
};


By enclosing the conditions in parentheses, you ensure that they are evaluated separately and then combined using the `&&` or `||` operator accordingly. This way, you can achieve your desired sorting based on the combination of `$param1` and `$param2`.

Give it a try and let me know if it works for you. Don't hesitate to ask if you have any further questions. Good luck!

Hey!

I can definitely understand the frustration you're facing while trying to dynamically combine two parameters within the `match()` expression in PHP. I've had a similar experience, and I found a workaround that might help you.

Instead of directly using the `&&` operator within the `match()` expression, you can use a ternary operator to achieve the desired combination. Here's an example:

php
$sortedData = match (true) {
($param1 && $param2) ? true : false => 'Sort condition 1',
($param1 || $param2) ? true : false => 'Sort condition 2',
default => 'Sort condition 3',
};


By using the ternary operator, you can evaluate the conditions `$param1 && $param2` and `$param1 || $param2` separately and set them to `true` or `false` accordingly. This way, you can dynamically combine the parameters within the `match()` expression.

Give it a shot and see if it works for your sorting needs. Feel free to reach out if you have any more questions or need further assistance. Good luck with your sorting function!
