How to sort an Array using If in PHP

Question

I have the following Array which contains data such as: Card, Month and Year. However, I receive it in a disorganized way and I would like to treat these values to follow the pattern. No Card, Year and Month or Month, Card and Year. I tried to use the sort() functions of php, but without success!

Array                                                                                                                    (
[0] => Array 
(
    [0] => 5522 8600 0000 0000
    [1] => 2020
    [2] => 09
)

[1] => Array 
(
    [0] => 09
    [1] => 5522 8600 0000 0000
    [2] => 2020
)

[2] => Array 
(
    [0] => 5522 8600 0000 0000
    [1] => 20
    [2] => 9
)                                                                                                    
)

I would like to create a function in which the Array is organized as follows:

 Array                                                                                                                   (
    [0] => Array 
    (
        [0] => 5522 8600 0000 0000
        [1] => 09
        [2] => 2020
    )

    [1] => Array 
    (
        [0] => 5522 8600 0000 0000
        [1] => 09
        [2] => 2020
    )

    [2] => Array 
    (
        [0] => 5522 8600 0000 0000
        [1] => 9
        [2] => 20
    )
)

Then comes the point of conditions, if as the Array the year 2020 is defined with only 2 decimal places, that is, 20 (19, 20, 21, 22, 23, ...) I would check if the value does not is greater than 12, following the number of months we have in 1 year, knowing this, to identify the year in this Array, I would apply another validation to check if the value is greater than 12 and if it has 2 or 4 digits, however I can't apply it in any way!

Thank you very much in advance!

Better to store these values as objects. Then store those objects in an array or list. Then, you wouldn't have to worry about the index of data inside the object. — Loki

Can you elaborate on No Card, Year and Month or Month, Card and Year ? As I see it, its just card, month and then year. — nice_dev

@nice_dev I would like to organize the Array, because after organizing it, I would transform it into JSON. — VanDecisive

As per your comment you can go with this solution:

$finalArray = [];
foreach($array as $key=>$arr){
    $arry = [];
    foreach($arr as $ar){
        
        if(strlen($ar) > 4){
            $arry[0] = $ar;
        }else if((strlen($ar) ==1 || strlen($ar) == 2) && (int)$ar <=12){
            $arry[1] = $ar;
        }else{
            $arry[2] = $ar;
        }
    }
    ksort($arry);
    $finalArray[$key] = $arry;
}

print_r($finalArray);

What about the card having month 11 and year 11 ? Your code will fail in that condition.

VanDecisive Over a year ago

It will not fail because of the API it receives, only from the year 2015 upwards, so there is no risk of failure, as it is a validation of credit / debit card

@JohnDoe I have already said first that it's like to be impossible to do it , but after reading all comment of OP i came up with this solution. Now it's OP's duty to check it and in case failed then let me know.

We can do this by comparing the number of values in the array then assign them the index position by going through the loop within the array.

But there is an issue.

[0] => Array 
(
    [0] => 5522 8600 0000 0000
    [1] => 20
    [2] => 20
)

According to your scenario, at one point you are showing 2020 as 20. So this can be possible that it can be a date too as I mentioned the above array. So by using this approach every logic will become failed.

Good as it is about validities, that is, month and year, in the key referring to the month: 09 (September) follows the pattern, which would be 12 months, values above that with 2 or 4 digits I can consider as the year, already the month I could create a validation that verifies the first digit of the value and check if it starts with 0 or 1 (using two decimal places) and if that value would not be greater than 12, that's why the use of If's, however I'm not managing to apply this in any way
