How to Fix mysqli_fetch_array() Parameter Discrepancy Error in PHP?

Error: mysqli_fetch_array() Parameter Discrepancy

In the provided code, the mysqli_fetch_array() function is encountering an error because it expects the first parameter to be a MySQL result object, but instead, it's receiving a boolean value. This indicates that the query executed by mysqli_query() has failed.

Resolution:

To resolve the issue, add the following code after mysqli_query():

<code class="php">if (!$check1_res) {
    trigger_error(mysqli_error($con), E_USER_ERROR);
}</code>

This statement will check if the query was successful. If it fails, it will display the MySQL error message, providing valuable information about the underlying cause of the problem.
