Question

I’m building an app which pulls records from a MongoDB. I’ve built the thead>tr>th as follows:

    // building table head with keys
    $cursor = $collection->find();
    $array = iterator_to_array($cursor);
    $keys = array();
    foreach ($array as $k => $v) {
            foreach ($v as $a => $b) {
                    $keys[] = $a;
            }
    }
    $keys = array_values(array_unique($keys));
    // assuming first key is MongoID so skipping it
    foreach (array_slice($keys,1) as $key => $value) {
        echo "<th>" . $value . "</th>";
    }

This gives me:

<thead>
    <tr>
        <th>name</th>
        <th>address</th>
        <th>city</th>
    </tr>
</thead>

This works very well, it grabs all the keys and builds the table head. I don’t have to specify anything and the thead is built dynamically from the data. The part I’m unable to figure out is building all of the tr>td’s

I can easily grab the info and build it like this:

$cursor = $collection->find();
$cursor_count = $cursor->count();
    foreach ($cursor as $venue) {
        echo "<tr>";
        echo "<td>" . $venue['name'] . "</td>";
        echo "<td>" . $venue['address'] . "</td>";
        echo "<td>" . $venue['city'] . "</td>";
        echo "</tr>";
    }

Doing so requires me to modify my php every time I add a new field. How can I build the tr>td’s automagically based on the data from mongodb like I am with the thead?

My data looks like this:

{
  "name": "Some Venue",
  "address": "1234 Anywhere Dr.",
  "city": "Some City"
}

Have you try to use second foreach as below

$cursor = $collection->find();
$cursor_count = $cursor->count();
    foreach ($cursor as $venue) {
        echo "<tr>";
        foreach (array_slice($keys,1) as $key => $value) {
           echo "<td>" . $venue[$value] . "</td>";
        }
        echo "</tr>";
    }
