What is the significance of the error message "Fatal error: Call to a member function bind_param() on a non-object" in PHP and how can it be resolved?

The error message "Fatal error: Call to a member function bind_param() on a non-object" in PHP typically occurs when trying to use the bind_param() method on a variable that is not an object, usually due to a failed query execution. To resolve this issue, you should check if the query execution was successful before trying to bind parameters.

// Assuming $stmt is your prepared statement object
if($stmt){
    $stmt->bind_param(...); // Bind parameters if the statement is valid
} else {
    // Handle the error or debug the issue
}
