Operator precedence in php javatpoint

PHP Operator is a symbol i.e used to perform operations on operands. In simple words, operators are used to perform operations on variables or values. For example: In the above example, + is the binary + operator, 10 and 20 are operands and $num is variable. PHP Operators can be categorized in following forms:
We can also categorize operators on behalf of operands. They can be categorized in 3 forms:
Arithmetic OperatorsThe PHP arithmetic operators are used to perform common arithmetic operations such as addition, subtraction, etc. with numeric values.
The exponentiation (**) operator has been introduced in PHP 5.6. Assignment OperatorsThe assignment operators are used to assign value to different variables. The basic assignment operator is "=".
Bitwise OperatorsThe bitwise operators are used to perform bit-level operations on operands. These operators allow the evaluation and manipulation of specific bits within the integer.
Comparison OperatorsComparison operators allow comparing two values, such as number or string. Below the list of comparison operators are given:
Incrementing/Decrementing OperatorsThe increment and decrement operators are used to increase and decrease the value of a variable.
Logical OperatorsThe logical operators are used to perform bit-level operations on operands. These operators allow the evaluation and manipulation of specific bits within the integer.
String OperatorsThe string operators are used to perform the operation on strings. There are two string operators in PHP, which are given below:
Array OperatorsThe array operators are used in case of array. Basically, these operators are used to compare the values of arrays.
Type OperatorsThe type operator instanceof is used to determine whether an object, its parent and its derived class are the same type or not. Basically, this operator determines which certain class the object belongs to. It is used in object-oriented programming. Output: Charu is a developer. bool(true) bool(false) Execution OperatorsPHP has an execution operator backticks (``). PHP executes the content of backticks as a shell command. Execution operator and shell_exec() give the same result.
Note: Note that backticks (``) are not single-quotes.Error Control OperatorsPHP has one error control operator, i.e., at (@) symbol. Whenever it is used with an expression, any error message will be ignored that might be generated by that expression.
PHP Operators PrecedenceLet's see the precedence of PHP operators with associativity.
Next TopicPHP Comments ← prev next → Which PHP operator has high precedence?Precedence of operators decides the order of execution of operators in an expression. For example in 2+6/3, division of 6/3 is done first and then addition of 2+2 takesplace because division operator / has higher precedence over addition operator +.
What are the types of operator precedence?operator precedence. What is the order of precedence of operators?In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.
What is precedence of operators explain with example?The precedence of operators determines which operator is executed first if there is more than one operator in an expression. Let us consider an example: int x = 5 - 17* 6; In C, the precedence of * is higher than - and = .
