Looping Through a stdClass Object in PHP

Question

I have a array called $result that contains the query results. When Loading the view, I'm passing the varible as a parameter. I'm trying to acess the values in [Document_No] [Line_No][Description] [Type] [Quantity] [Unit_of_Measure] and display them to the user.

I have tried to loop through the array and keep getting this error. Cannot use object of type stdClass as array

Values of $result

No need to use this loop foreach ($lines as $line). You can use directly $lines->Description

You have an array of objects. Each object has properties that can be referenced.

So, for the array $result, you can iterate through the array.

foreach($result as $row) {}

Each row, however, is an object; properties of an object are referenced like so: $row->Document_No

So if you were wanting to print out a table using fields [Document_No] [Line_No][Description] [Type] [Quantity], you could do this:

<?php
// do whatever to get $result

// php logic finished...
?>
<table>
  <tr>
    <th>Document_No</th>
    <th>Line_No</th>
    <th>Description</th>
    <th>Type</th>
    <th>Quantity</th>
  </tr>
  <?php foreach($result as $row): ?>
  <tr>
    <td><?= $row->Document_No ?></td>
    <td><?= $row->Line_No ?></td>
    <td><?= $row->Description?></td>
    <td><?= $row->Type ?></td>
    <td><?= $row->Quantity ?></td>
  </tr>
  <?php endforeach; ?>
</table>

For a form, the same idea applies:

<?php foreach($result as $index => $row): ?>
<input disabled id="description" class="form-control input-group-lg reg_name" name=“description[<?= $index ?>]” value=“<?= $row->Description?>” >


...
<?php endforeach; ?>
