How to Join a String recursively in a Loop in PHP

I am reading some JSON data and want to return it as a text from a function. For that, I am doing the following.

<?php

    $json = '{"Business":["Accounting","Macroeconomics"],"0":["English","English","Other","Penmanship"],"Math":["Calculus","Fractions","Functions"],"Other":["Geography","Philosophy"],"Science":["Geology","Physical Science"]}';
    
    $json1 = json_decode($json, true);
    
    
    function rex($json){
        
        foreach ($json as $key=>$value){
            $x='<tr>
                <td style="width:30%;font-weight:700;padding-bottom:10px">'.$key.'</td>
                <td>'.implode(' ,',$value).'</td>
               </tr>';
           echo $x;
        }
    }
    
    rex($json1);
    
    ?>

I can't figure out how to generate a final concatenated string from the function. If I echo it then it returns what I want but how to capture that output inside a variable. $x.=$x doesn't help either. I am a beginner in PHP these days.

return from the function and use concatenation.

...
function rex($json){
  $x = '';
  foreach ($json as $key => $value) {
    $x .= '
    <tr>
      <td style="width:30%;font-weight:700;padding-bottom:10px">'.$key.'</td>
      <td>'.implode(', ',$value).'</td>
    </tr>';
  }
  return $x;  
}
    
echo rex($json1);
