Why Am I Getting the \"Cannot use mysqli_Result Object as Array\" Error?

Cannot Use mysqli_Result Object as Array

Encounters the error "Cannot use object of type mysqli_result as array," typically when attempting to perform array-based operations on a result object returned by a MySQL query using the MySQLi extension.

Explanation:

A mysqli_result object, returned by the $mysqli->query() function, represents the result of a query and contains the data retrieved from the database. It is not an array itself and cannot be used as one.

Solution:

To access the row data as an array, you need to fetch the row using the following methods:

• $result->fetch_assoc(): Fetch the row as an associative array, with column names as keys.
• $result->fetch_array(MYSQLI_ASSOC): Fetch the row as an associative array, with column names as keys.
• $result->fetch_array()/$result->fetch_row(): Fetch the row as a numeric array, with column numbers as keys.

Revised Code:

The following modified code in line 303 fetches the row as an associative array using $result->fetch_assoc():

<code class="php">//Check if requested username can be followed.
if (in_array($followingdata['usergroupid'], explode("|", $vbulletin->options['subscribetouser_usergroups_cannot']))){
    exit;
}</code>

Alternatively, you could also use $result->fetch_array(MYSQLI_ASSOC) to fetch the row as an associative array.
