I'm currently working on a project where I need to include a PHP variable inside a MySQL statement, but I'm not quite sure how to go about it. I have been searching online and came across a few different methods, but wanted to see if anyone here could provide some guidance.
To give you some context, I have a PHP variable named `$username` which holds the value of the current user's name. I want to use this variable in a MySQL statement to retrieve data specific to that user from the database.
Here's what I have so far:
$username = "John Doe"; // Just an example value, I actually get this dynamically from the user
$sql = "SELECT * FROM users WHERE username = '$username'";
Is this the correct way to include a PHP variable inside a MySQL statement? Or should I be doing it differently? I want to make sure that I'm not vulnerable to SQL injection attacks or any other security issues.
Any help or suggestions would be greatly appreciated. Thanks in advance!
