How can the error message "Query failed: Query was empty" be resolved in PHP?

The error message "Query failed: Query was empty" typically occurs when trying to execute an SQL query that is empty or missing. To resolve this issue, ensure that the SQL query string is properly constructed and not empty before executing it in PHP. 

// Check if the SQL query is not empty before executing
if (!empty($sql_query)) {
    // Execute the SQL query
    $result = mysqli_query($connection, $sql_query);
    
    // Check if the query was successful
    if ($result) {
        // Process the result
    } else {
        // Handle the query failure
        echo "Query failed: " . mysqli_error($connection);
    }
} else {
    // Handle the case where the SQL query is empty
    echo "Error: SQL query is empty";
}
