How can I use `AND`/`OR` in an `if`/`else` statement in PHP?

In PHP, you can use AND and OR in if/else statements to combine conditions:

1. AND (&&) ensures that all conditions must be true for the code to run.
2. OR (||) ensures that the code runs if at least one condition is true.
3. Combining AND and OR allows you to create more complex logic, and it’s important to use parentheses to make the order of evaluation clear.
4. and and or (lower precedence) are alternatives, but they should be used carefully due to their different precedence compared to && and ||.

Always prioritize readability when combining conditions.
