How to Fix the \"Cannot Use Object of Type mysqli_result as Array\" Error in PHP?

Troubleshooting "Cannot Use Object of Type mysqli_result as Array" Error in PHP

To resolve the error message "Fatal error: Cannot use object of type mysqli_result as array," which typically occurs in PHP code related to database operations, follow these steps:

Understanding the Error:

The error indicates that you are attempting to use a mysqli_result object as an array when it should be treated as an object returned by a database query.

Inspecting the Code:

In your case, the code in line 303 attempts to use $followingdata['usergroupid'] as an array element, but since it is a mysqli_result object, it cannot be used directly as an array.

Solution:

To fix the issue, you need to fetch the result row from the $result object as an associative array. This can be achieved using either mysqli_fetch_assoc() or mysqli_fetch_array().

Corrected Code:

Instead of accessing the usergroupid property directly, use mysqli_fetch_assoc() to fetch the result row as an associative array:

<code class="php">$result = $vbulletin->db->query_write("SELECT * FROM user WHERE userid = $followinginfo[userid]");
$followingdata = $result->fetch_assoc();</code>

Alternatively:

You can also use mysqli_fetch_array() to fetch the result row as an array:

<code class="php">$followingdata = $result->fetch_array(MYSQLI_ASSOC);</code>

Applying the Solution:

Make the necessary changes in your code, and the error should be resolved. Remember to fetch the result row as an associative array before accessing it as an array.
