How to pass values into an array in php?

I am working on a php code as shown below in which the values (let us supposed I entered 12, 13, 14) of $data->{"articles_id_" . ICL_LANGUAGE_CODE} is coming through admin portal. Let us suppose I have entered 12, 13, 14 for "articles_id_" . ICL_LANGUAGE_CODE

Php code:

'post__in' => array($data->{"articles_id_" . ICL_LANGUAGE_CODE}),

On debug it is returning:

[post__in] => Array
    (
        [0] => 12, 13, 14
    )

Whereas I want to be returned like this:

[post__in] => Array
(
    [0] => 12
    [1] => 13
    [2] => 14
)

Problem Statement:

I am wondering what changes I should make in the php code above so that its return in the way I want.

You can use this too:

'post__in' => str_getcsv($data->{"articles_id_" . ICL_LANGUAGE_CODE}),

str_getcsv — Parse a CSV string into an array

str_getcsv( string $input,string $delimiter=",",string $enclosure='"',string $escape="\" ) :array

https://www.php.net/manual/en/function.str-getcsv.php

Then if it has ,\s you can trim using array map.

'post__in' => array_map('trim', str_getcsv($data->{"articles_id_" . ICL_LANGUAGE_CODE})),

In this case it's similar to explode or preg_split, but those were taken already as answers ... :-p

This treats it more like a CSV line so it will deal with things like this foo,"Some other thing",bar - Some CSV formats (includng PHP fputcsv and SplFileObject::fputcsv will enclose strings with spaces or commas with double quotes ". Explode/Preg Split would retain the " but this would remove them. It also does a few other things that are CSV related. But as I said, in this case with integers it's basically the same as explode(',', ...)

Cheers!

Explode or preg_split.

Explode is static and must have both comma and space.

'post__in' => explode(", ",$data->{"articles_id_" . ICL_LANGUAGE_CODE}),

Preg_split can have an optional space, meaning it can split strings like "12,13,14" and "12, 13, 14" and even "12, 13, 14" which explode can't.

'post__in' => preg_split("/,\s*/",$data->{"articles_id_" . ICL_LANGUAGE_CODE}),

If it's user input you need to split then I would definitely go for preg_split.
It's very common for "normal" people (not programmers) to write numbers with space in-between.

'post__in' => explode(',', $data->{"articles_id_" . ICL_LANGUAGE_CODE}),

If the value of $data->{"articles_id_" . ICL_LANGUAGE_CODE} is a comma-separated string, you should explode() it:

'post__in' => explode(",", $data->{"articles_id_" . ICL_LANGUAGE_CODE})
