PHP does not output isset array from Mysql. Although through print_r the array is displayed

The Mysql command is set correctly, since the data is displayed correctly via print_r($ads). I pack the resulting array into $ads

Catch id

$id = htmlentities($_GET['id']);

Query DB.

SELECT
     rent.id, 
     rent.run,
     rent.year,
   FROM rent
     WHERE rent.id = '.$id.'
          ORDER BY rent.time_upload DESC');

But through the isset function, they are not shown, no errors are displayed, nothing, just a blank page.

I output the data like this

<?php if (isset($ads)): ?>

      <h3> 
 
          <?=$ads['id'];?> 
             <?=$ads['run'];?>
                    <?=$ads['year'];?>  

 
      </h3>
          
<?php endif; ?>

short_tags are included in PHP.

Please help solve the problem.

Answer

You’re not going deep enough. $ads['run'] doesn’t exist, only $ads['3625']['run'] does. Try:

<?php
foreach( $ads as $ad ) {
    ?>
    <h3> 

      <?=$ad['id'];?> 
         <?=$ad['run'];?>
                <?=$ad['year'];?>  


  </h3>
  <?php
 }
