What are potential pitfalls when confusing PHP and MySQL functions?

Mixing up PHP and MySQL functions can lead to errors in your code and potentially security vulnerabilities. To avoid this, always make sure to use the correct functions for each task - PHP functions for handling data and logic, and MySQL functions for interacting with the database. Be mindful of the syntax and parameters required for each function to prevent confusion. 

// Correct way to query a MySQL database using PHP
$connection = mysqli_connect("localhost", "username", "password", "database");
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
if($result){
    // Process the result
} else {
    // Handle any errors
}
mysqli_close($connection);
