PHP数组到HTML表问题

Question

I have my code working to some degree as it echo's out my array to a table - but the issue is, it's echoing out all fields.

I want to display just the name, trainer and status fields. I just can't get my head around how to do it.

Array

[{
id: "8001073",
name: "Castarnie",
silk: "c20170311her/00829186.jpg",
cloth_number: "4",
jockey: "Harry Cobden",
trainer: "Robert Walford",
weight_value: "165",
weight_unit: "pounds",
form: "P-2P2PF",
bred: "GB",
last_run: "21",
status: "WINNER"
},
{
id: "7164976",
name: "Try It Sometime",
silk: "c20170311her/00026136.jpg",
cloth_number: "8",
jockey: "Mikey Hamill",
trainer: "Sheila Lewis",
weight_value: "140",
weight_unit: "pounds",
form: "654529",
bred: "IRE",
last_run: "20",
status: "LOSER"
}
]

and the PHP code looks like

<?php if (count($obj) > 0): ?>
<table>
  <thead>
    <tr>
      <th><?php echo implode('</th><th>', array_keys(current($obj))); ?></th>
    </tr>
  </thead>
  <tbody>
<?php foreach ($obj as $row): array_map('htmlentities', $row); ?>
    <tr>
      <td><?php echo implode('</td><td>', $row); ?></td>
    </tr>
<?php endforeach; ?>
  </tbody>
</table>
<?php endif; ?>

It doesn't make sense to call array_map() to modify every value in each row with htmlentities because you are only displaying three of them -- only modify what you are going to display.

Code: (Demo)

$json_data=file_get_contents($api_url);    
$objects=json_decode($json_data);
if(is_array($objects) && sizeof($objects)){
    echo '<table><thead><tr>';
        echo '<th>Name</th><th>Trainer</th><th>Status</th>';
    echo '</tr></thead><tbody>';
    foreach($objects as $row){
        echo '<tr>';
            echo '<td>',htmlentities($row->name),'</td>';
            echo '<td>',htmlentities($row->trainer),'</td>';
            echo '<td>',htmlentities($row->status),'</td>';
        echo '</tr>';
    }
    echo '</tbody></table>';
}else{
    echo 'Invalid or empty json data received';
}

Output:

<table>
    <thead>
        <tr>
            <th>Name</th>
            <th>Trainer</th>
            <th>Status</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Castarnie</td>
            <td>Robert Walford</td>
            <td>WINNER</td>
        </tr>
        <tr>
            <td>Try It Sometime</td>
            <td>Sheila Lewis</td>
            <td>LOSER</td>
        </tr>
    </tbody>
</table>
