Operator PrecedencePHP ManualPrevChapter 10. OperatorsNextOperator Precedence The precedence of an operator specifies how "tightly" it binds two expressions together. For example, in the expression 1 + 5 * 3, the answer is 16 and not 18 because the multiplication ("*") operator has a higher precedence than the addition ("+") operator. The following table lists the precedence of operators with the lowest-precedence operators listed first. Table 10-6.
