What do php operators mean?

An operator is something that takes one or more given values ​​(an expression, in programming jargon) and produces another value (thus the entire structure becomes an expression).

Operators can be grouped according to how many values ​​they can accept. Unary operators can only accept one value, such as ! (logical negation operator) or (increment operator). Binary operators accept two values, such as the familiar arithmetic operators - (add) and - (subtract), which are the majority of PHP operators. Finally, there is the only ternary operator ? :, which accepts three values; it is often simply called the "ternary operator" (although it might be more appropriate to call it a conditional operator).

php operators include arithmetic operators, assignment operators, increment\decrement operators, comparison operators, logical operators, array operators, ternary operators, and combined comparison operators.

See the Operators chapter for a complete list of PHP operators.
