Write a PHP class called 'Calculator' that has a private property called 'result'. Implement methods to perform basic arithmetic operations like addition and subtraction. Sample Solution: PHP Code : <?phpclassCalculator{private$result;publicfunction__construct(){$this->result=0;}publicfunctiongetRes...
First, we’ll illustrate how to perform arithmetic operations with increment and decrement operators by providing an example with pre-increment. The following script increments the value of the variable $number by 1, stores the new value in the variable $result and then outputs its v...
The function should handle addition (+), subtraction (-), multiplication (*), and division (/) operations. For division, return null if the second number is zero. If the operator is not one of the valid arithmetic operators, return null....
Arithmetic Operators These operators perform mathematical operations on variables and values. Operations such as addition(+), multiplication(*), subtraction(-), etc. can be performed. Comparison Operators These Operators are used to compare two variables or values and return boolean values, true or...
Performing Operations: $sum = $x + $y; $difference = $x - $y; $product = $x * $y; $quotient = $x / $y; Concatenating Strings: $greeting = "Hello, " . $name . "!"; Printing Values: echo $name; echo "$greeting";Comments in ...

You can perform basic arithmetic operations on big numbers in PHP using the BC Math or GMP functions. For example, to add two big numbers, you can use the bcadd() function:$sum = bcadd($num1, $num2). Similarly, to multiply two big numbers, you can use the bcmul() function:$product...
