It had to do with working around another function to exploit the injection. It's good to mention, that in same rare cases, addslashes could by bypassed [1]. In the context of web applications, user input comes from HTTP input. g. Assuming that GET parameter 'id' in digits-only, the best thing to do is to check if ID really contains digits only, by for example converting it into an INT (and catch the exception if any), Our security expert explains why single quotes matter in SQL injection attacks and how using Prepared Statements (also called Parameterized Queries) can effectively prevent Single quotes play a crucial role in SQL queries, often used to delimit string literals. The example uses a version of the "Magical Code Injection In SQL, when dealing with user-generated input for database inserts, it is crucial to properly handle special characters like single quotes ('), to prevent SQL injection attacks and As a result, any malicious payload that starts with a double quote will remain unescaped inside the final query, enabling injection.
