How can the error "Call to a member function bind_param() on a non-object" be resolved in mysqli prepared statements?

The error "Call to a member function bind_param() on a non-object" occurs when the prepared statement object is not created successfully, usually due to a syntax error in the SQL query. To resolve this issue, make sure the SQL query is correct and the prepare() method returns a valid statement object before calling bind_param(). 

// Correct the SQL query and ensure the prepare() method returns a valid statement object
$stmt = $conn->prepare("SELECT * FROM table_name WHERE column_name = ?");
if ($stmt) {
    // Bind parameters and execute the statement
    $stmt->bind_param("s", $param_value);
    $stmt->execute();
    // Rest of the code to fetch results
} else {
    echo "Error in preparing the statement.";
}
