【解決方法】データベースからデータをより簡単に取得する方法、または取得したデータをフィルタリングする方法は?

I'm building a business listing website, and fetching all data from a database. The problem was that if I wrote a function for all the boxes uniformly, only the first one with the specified id would work. So I got the code below to do the work.

<?php
    if(is_array($fetchData)){      
    $sn=1;
    foreach($fetchData as $data){
?>

<div class="content">

    
<div id= <?php echo $data['id']??''; ?> class="business" style="border: 1px solid rgb(0, 0, 0);height: 100px;width: 400px;padding: 2px;overflow: hidden;">
    <container class="boxholder1">

    <div class="box1">
        <div id="titleLine">
            <p><img class="brandlogo" src="image/logo.png" alt=""</p>
            <p class="brandname"><?php echo $data['businessname']??''; ?></p>
        </div>
            )            
    <div id="datas"><div id="list">
        <p>County:<?php echo $data['county']??''; ?></p>
        <p>CITY: <?php echo $data['city']??''; ?></p>
        <p>Phone: <?php echo $data['phone']??''; ?></p>
        <p>EMAIL: <?php echo $data['email']??''; ?></p>
    </div>
  
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>    
    <script>

        $("#<?php echo $data['id']??''; ?>").click(function(){
        if($("#<?php echo $data['id']??''; ?>").css('height') === "500px")
            $("#<?php echo $data['id']??''; ?>").css('height', '100px');
        else
            $("#<?php echo $data['id']??''; ?>").css('height', '500px');
        })
        $("#<?php echo $data['id']??''; ?>").click(function(){
        if($("#<?php echo $data['id']??''; ?>").css('width') === "800px")
            $("#<?php echo $data['id']??''; ?>").css('width', '400px');
        else
            $("#<?php echo $data['id']??''; ?>").css('width', '800px');
        })
        
    </script> 

    </div>
    <?php
    $sn++;}}else{ ?>
<?php
}?>

Surprisingly, it works perfectly for its purpose the boxes get displayed as I wanted, and the function works well too for each one of them. But now I want to filter the boxes by e.g location etc. and can't really get a solution for that.

I tried multiple ways for the filtering, but nothing really works, cause I can't reference all the boxes. That's why I need a simpler solution for displaying them or a working solution for the filtering, I'd preferably keep the same concept with the expandable boxes. Any idea is highly appreciated!
