How can the warning "Number of variables doesn't match number of parameters in prepared statement" be resolved when using mysqli_stmt::bind_param() in PHP?
When using mysqli_stmt::bind_param() in PHP, the warning "Number of variables doesn't match number of parameters in prepared statement" occurs when the number of variables passed to bind_param() doesn't match the number of placeholders in the prepared SQL statement. To resolve this issue, make sure the number of variables passed to bind_param() matches the number of placeholders in the SQL query.
// Example of resolving the warning "Number of variables doesn't match number of parameters in prepared statement"
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);
// Make sure the number of variables passed to bind_param() matches the number of placeholders in the SQL query
