How to implement multiplication in php

Operator refers to certain symbols that generate another value through one or more expressions, such as " ", "%", ".", etc. are all operators.

In the expression 2 1, the operator " " has two operands, 1 and 2. An operator with two operands can be called a binary operator, and an operator with one operand is called a unary operator.

Next, I will give you a brief introduction to the commonly used operators in PHP.

The following table:

The example is as follows:

<?php 
$x=10; 
$y=6;
echo ($x + $y); // 输出16
echo &#39;<br>&#39;;  // 换行
echo ($x - $y); // 输出4
echo &#39;<br>&#39;;  // 换行
echo ($x * $y); // 输出60
echo &#39;<br>&#39;;  // 换行
echo ($x / $y); // 输出1.6666666666667
echo &#39;<br>&#39;;  // 换行
echo ($x % $y); // 输出4
echo &#39;<br>&#39;;  // 换行
echo -$x;
?>
