If user input is inserted without modification into an SQL query, then the application becomes vulnerable to SQL injection, like in the following example:
$unsafe_variable = $_POST['user_input'];

value'); DROP TABLE table;--, and the query becomes:
column) VALUES('value'); DROP TABLE table;--')
What can be done to prevent this from happening?
