Does `mysqli_real_escape_string` Offer Sufficient Protection Against SQL Injection?

Can "mysqli_real_escape_string" Effectively Prevent SQL Injection and Attacks?

While "mysqli_real_escape_string" is an essential step in safeguarding against SQL injection, it isn't the ultimate defense. As demonstrated in SQL injection examples, this function can be bypassed, leaving your database vulnerable.

To truly protect against SQL injection and other SQL attacks, the industry standard recommends using prepared statements. By separating data (parameters) from SQL queries, prepared statements effectively prevent data contamination and maintain query integrity. This approach effectively eliminates opportunities for malicious actors to exploit vulnerabilities.

However, in specific scenarios where prepared statements cannot be employed, implementing a rigorous whitelist can provide a reliable safeguard. By restricting the permissible values for each parameter, you can prevent the introduction of malicious characters or code into your queries, ensuring data protection and security.
