How to pass data from the database to modal

Hello, I have a website offline and I'm in need of a function that I think is complex. I wanted, when loading an image, that comes from the database, open a modal with the information about it. I'll explain, my site is about companies and when we upload an image of the company I wanted to open a modal with the rest of the information, contacts, location, etc ...

<div class="col-md-12" style="margin-top:20px">
    <div class"container-fluid">
        <div class="row" align="center">
            <?php
                $empresas="SELECT * FROM empresa ORDER BY Nome";
                $query_empresas=$ligacao->query($empresas) or die ('erro ligacao');

                while($linha=$query_empresas->fetch_assoc())
                {     
            ?>          
                <div class="col-md-3">
