1. What are Logical Operators?
In programming, logical operators are tools that allow you to combine or modify conditions to perform more complex evaluations. In PHP, the most common logical operators are &&(and), ||(or), and !(not).
2. Operator "and" ( &&):
The (and) operator &&is used to combine two conditions, and the resulting expression will be true only if both conditions are true. Let's look at an example:
