Are there any potential pitfalls or security risks in using conditional statements like if($user['level'] >= "0") in PHP code?

Using loose comparison operators like ">=" can lead to unexpected behavior, especially when comparing different data types. To avoid potential pitfalls or security risks, it is recommended to use strict comparison operators (===) and ensure that the variable being compared is of the correct type.

if($user['level'] >= 0) {
    // Code block for users with level greater than or equal to 0
}
