💻 3 Mistakes Beginners Make in PHP/MySQL (and how to fix them)
🚫 1. Not using prepared statements
Many beginners write queries like:
$query = "SELECT * FROM users WHERE email = '$email'";
👉 This is dangerous (SQL Injection 😬)
✅ Fix: Use prepared statements (MySQLi/PDO)
More secure + professional
🚫 2. Mixing PHP and HTML everywhere
Code becomes messy like spaghetti 🍝
Hard to debug, harder to scale
✅ Fix:
Separate logic and UI
Use functions or basic MVC structure
🚫 3. No error handling / debugging
“White screen of death” and you’re stuck 😭
✅ Fix:
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
Or at least:
error_reporting(E_ALL);
ini_set('display_errors', 1);
🔥 Bonus Tip:
Always validate user input before sending to database!
