How to get repeatable form-field data?

Question

I'm using Repeatable field Type.

The data from database are:

{"social_icon":["fa fa-facebook","fa fa-twitter","fa fa-linkedin"],"social_link":["https://www.facebook.com/user","https://www.twitter.com/user","https://www.linkedin.com/user"]}

array made wit $array_links = json_decode($social_links, true);

Array ( [social_icon] => Array ( [0] => fa fa-facebook [1] => fa fa-twitter [2] => fa fa-linkedin ) [social_link] => Array ( [0] => https://www.facebook.com/user [1] => https://www.twitter.com/user [2] => https://www.linkedin.com/user ) ) 1

if I get information through loop:

<?php foreach ($array_links as $key => $value) {
                foreach ($value as $content) {
                    echo $content.'<br>';
                }
            } ?>

It shows me the following

fa fa-facebook
fa fa-twitter
fa fa-linkedin
https://www.facebook.com/user
https://www.twitter.com/user
https://www.linkedin.com/user

I want to build it:

<a href="https://www.facebook/user"><i class="fa fa-facebook"></i></a>

get data with $array_links[0][1];not serve me, because they use some 6 links, and other links will not use.

Thanks for helping me.

You could group each set of field by the key.

Call the parameter and convert to array:

$social_links = $params->get('social_links');
$array_links = json_decode($social_links, true);

Create a function in your helper.php that will group them by key

public function group_by_key($array) 
{
    $result = array();

    foreach ($array as $sub) 
    {
        foreach ($sub as $k => $v) 
        {
            $result[$k][] = $v;
        }
    }
    return $result;
}

Then push $array_links through the function and called it in mod_mymodule.php

$filtered_array = group_by_key($array_links);

Then loop through the result and display however you liek:

foreach ($filtered_array as $key => $val) 
{   
    echo '<a href="' . $val[0] . '"><i class="' . $val[1] . '"></i></a>';
}
