Create a json viewer for nested n level in PHP

i want to create a json viewer for an api that converts a json to a list of table, can someone point me how its done? i know its possible but i don’t know how to do it.

e.g.

{"name":diana,
"age":12,
"gender":"male"}

to:

<table>
  <tr>
   <td>name:</td><td>diana</td>
  </tr>
  <tr>
   <td>age:</td><td>12</td>
  </tr>
  <tr>
   <td>gender:</td><td>male</td>
  </tr>
</table>

if something is not clear please let me know :) i forgot to mention that i will be working for a nested json. m(_ _)m

Solution

  • Use json_decode to parse json, then iterate over the result...

    echo "<table>\n";
$data = json_decode($json, true);
foreach($data as $key=>$value) echo "<tr><td>{$key}:</td><td>{$value}</td></tr>\n";
echo "</table>\n";

    Note that this will work only for such "simple" json objects as you gave in example... If theres multi-level nesting, this won't be enough. You will have to check the type of $value and decide how to print it at any level of nesting...

    Also note, that json string can also be not an object at all. It can also be a primitive type.

    Ultimately, you either have a multidimensional array, or an object (if you ommit the second parameter from json_decode call). From that point on, the 'goal' changes from pretty-print a json object into pretty-print a php variable. There are plenty of solutions for that.
