Description: Operator precedence in programming languages refers to the rules that determine the order in which operations are performed in expressions. These rules are fundamental to ensure that expressions are evaluated in a predictable and correct manner. In PHP, as in other programming languages, operators have different levels of precedence, meaning that some operators are executed before others. For example, arithmetic operators like multiplication and division have a higher precedence than addition and subtraction. This implies that in an expression combining different operators, the result may vary depending on how operations are grouped. Additionally, operator precedence is also influenced by the use of parentheses, which can alter the order of operation evaluation. Understanding operator precedence is essential to avoid logical errors in code and to write expressions that yield the expected results. In summary, operator precedence is a key concept in programming that directly affects how expressions are evaluated and, consequently, the behavior of the code.
