How can the error "Unknown column in 'where clause'" be resolved when deleting records from a database in PHP?

When deleting records from a database in PHP, the error "Unknown column in 'where clause'" typically occurs when the column specified in the WHERE clause does not exist in the table. To resolve this issue, double-check the column name in the WHERE clause to ensure it matches the actual column name in the table. 

// Assuming $conn is the database connection object

// Specify the correct column name in the WHERE clause
$id = 1;

// SQL query to delete a record from the table where the column name is 'id'
$sql = "DELETE FROM table_name WHERE id = :id";

// Prepare the SQL statement
$stmt = $conn->prepare($sql);

// Bind the parameter
$stmt->bindParam(':id', $id);

// Execute the statement
$stmt->execute();
