SQL Injection Protection prevents execution of malicious SQL code.
Protection methods:
- Using Eloquent/Query Builder
- Prepared statements
- Parameter binding
- Avoiding raw queries
Examples
Safe Query (Good)
User::where('email', $email)->first();
DB::table('users')->where('email', $email)->first();
Using Eloquent/Query Builder which automatically does parameter binding.
Unsafe Query (Bad)
DB::select("SELECT * FROM users WHERE email = '{$email}'");
This method is dangerous and vulnerable to SQL Injection.
