PHP Operators
PHP Operators Overview
PHP operators include arithmetic and logical, with precedence rules.
Introduction to PHP Operators
PHP operators are symbols that tell the PHP processor to perform specific operations. They are essential in controlling the logic and flow of a program. PHP operators can be categorized into several types, including arithmetic, logical, comparison, and assignment operators. Understanding these operators and their precedence is crucial for writing efficient and effective PHP code.
Arithmetic Operators
Arithmetic operators are used to perform mathematical operations on variables and values. PHP supports standard arithmetic operations such as addition, subtraction, multiplication, division, and modulus.
Logical Operators
Logical operators are used to combine conditional statements. PHP includes operators like AND
(&&
), OR
(||
), and NOT
(!
).
Operator Precedence
Operator precedence determines the order in which operations are performed in an expression. Operators with higher precedence are evaluated first. In PHP, arithmetic operators have a higher precedence than logical operators.
Consider the following example:
In the above code, the multiplication is performed before addition because multiplication has a higher precedence.
