Code to find product of two numbers in PHP
Product of two numbers using function – #1
Program 1
- Start PHP script
- Declare two integer variable as parameter
- Calculate product of given two numbers and return the value to main
- Calling the function with passing argument
- Display result on the screen
- Exit PHP

<h3>Multiply two number using function</h3>
<?php //php script
//function definition with parameter
function mulTwoNumbers($x, $y)
{
return $x * $y;
//calculate the product of two numbers using function
//and return the product of given number
}
//Calling the function with argument to print result
echo "The product of 5 and 12: ".mulTwoNumbers(5,12);
echo "<br>";
echo "The product of 5 and -10: ".mulTwoNumbers(5,-10);
echo "<br>";
echo "The product of -12 and -13: ".mulTwoNumbers(-12,-13);
echo "<br>";
//exit php
?>
</body>
</html>

}
//Calling the function and print result
echo "The product of 15 and 10: ";
echo mulTwoNumbers(15,10);
echo "<br>";
echo "The product of 25 and 10: ";
echo mulTwoNumbers(25,10);
echo "<br>";

echo mulTwoNumbers(15,-12);
echo "<br>";
//exit php
?>
When the above code is executed, it produces the following result
Multiply two number using function
The product of 15 and 10: 150 The product of 25 and 10: 250 The product of 15 and -12: -180
