PHP function with unknown number (Regexp type) $childIds[] = X,$child->id

Usually I end up finding a solution by browsing StackOverflow, but here I come up short!

Here is the structure of my categories in the database

Parent category A (category_id = 1)
Child category B (category_id = 2)
Child category C (category_id = 3)
Child category D (category_id = 4)
Child category E (category_id = 5)

Basically my Joomla extension does not allow you to classify a Page in several categories at the same time.
But I managed to get around this by modifying some php files, and adding several category_id values (separated by commas)

My code that works. But it’s just too long. I would like to simplify it.
I had to create all the scenarios, depending on the position of the numbers.

My code :

// Get all child ids from this category
$categoryModel = ES::model('ClusterCategory');
$childs = $categoryModel->getChildCategories($activeCategory->id, [], SOCIAL_TYPE_PAGE, array('state' => SOCIAL_STATE_PUBLISHED));

$childIds = [];

foreach ($childs as $child) {
    $childIds[] = "1,$child->id";
    $childIds[] = "2,$child->id";
    $childIds[] = "3,$child->id";
    $childIds[] = "4,$child->id";
    $childIds[] = "5,$child->id";
    $childIds[] = "$child->id,1";
    $childIds[] = "$child->id,2";
    $childIds[] = "$child->id,3";
    $childIds[] = "$child->id,4";
    $childIds[] = "$child->id,5";   
    $childIds[] = "1,$child->id,2";
    $childIds[] = "2,$child->id,3";
    $childIds[] = "3,$child->id,4";
    $childIds[] = "4,$child->id,5";
    $childIds[] = "5,$child->id,1";
    $childIds[] = "2,$child->id,1";
    $childIds[] = "3,$child->id,2";
    $childIds[] = "4,$child->id,3";
    $childIds[] = "5,$child->id,4";
    $childIds[] = "1,$child->id,5";
    $childIds[] = $child->id;
}

My question :
How to insert a variable instead of the number?
I tried Regexp, and many other things.

As in an equation with an unknown.
$childIds[] = X,$child->id,X;

Thank you,
Philippe

    @patrick-simard Thank you very much Patrick. It works wonderfully well ! And if there are 4 values with 3 commas, how can I adapt your code ? I tried that, but it doesn't work.

    for ($k = 1; $k <= 50; $k++)
{ if ($i != $k)
{ $childIds[] = "$child->id,$i,$j,$k";
$childIds[] = "$i,$child->id,$j,$k";
$childIds[] = "$i,$j,$child->id,$k";
$childIds[] = "$i,$j,$k,$child->id";
}
}

    You should be using nested loops instead

    $categoryModel = ES::model('ClusterCategory');
$childs = $categoryModel->getChildCategories($activeCategory->id, [], SOCIAL_TYPE_PAGE, array('state' => SOCIAL_STATE_PUBLISHED));

$childIds = [];

foreach ($childs as $child) {
    for ($i = 1; $i <= 5; $i++) {
        $childIds[] = "$i,$child->id";
        $childIds[] = "$child->id,$i";
        
        for ($j = 1; $j <= 5; $j++) {
            if ($i != $j) {
                $childIds[] = "$i,$child->id,$j";
            }
        }
    }
}

    This way, you can easily adjust the range of numbers by changing the loop boundaries, and the code will be more maintainable.
