How to Access Individual Columns from a MySQL Query Result?

Accessing Individual Columns from a MySQL Query

In MySQL, the mysqli_fetch_array() function can be used to retrieve rows from a query result as an associative array. However, when iterating over multiple rows, it's common to encounter an issue where all the columns from a given row are combined into a single array element.

Solution:

To address this and access the columns separately, you can utilize the following approach:

<code class="php">$posts = [];

while ($row = mysqli_fetch_array($result)) {
  $posts[] = array(
    'post_id'   => $row['post_id'],
    'post_title' => $row['post_title'],
    'content'    => $row['content'],
    // Add additional columns as needed...
  );
}</code>

With this modified code:

  • The $posts array now stores each row as an associative array, with column names as array keys.
  • You can access individual columns by accessing specific keys within the nested array. For instance, $posts[0]['post_id'] would retrieve the first post's ID.

By utilizing this approach, you can efficiently iterate over multiple rows in a query result and access the columns individually, enabling you to manipulate and process the data as desired.
