PHP Parameterized FunctionPHP Parameterized functions are the functions with parameters. You can pass any number of parameters inside a function. These passed parameters act as variables inside your function. They are specified inside the parentheses, after the function name. The output depends upon the dynamic values passed as the parameters into the function. PHP Parameterized Example 1
Addition and Subtraction In this example, we have passed two parameters $x and $y inside two functions add() and sub().
<!DOCTYPE html>
<html>
<head>
<title>Parameter Addition and Subtraction Example</title>
</head>
<body>
<?php
//Adding two numbers
function add($x, $y) {
$sum = $x + $y;
echo "Sum of two numbers is = $sum <br><br>";
}
add(467, 943);
//Subtracting two numbers
function sub($x, $y) {
$diff = $x - $y;
echo "Difference between two numbers is = $diff";
}
sub(943, 467);
?>
</body>
</html>

PHP Parameterized Example 2
Addition and Subtraction with Dynamic number In this example, we have passed two parameters $x and $y inside two functions add() and sub().
<?php
//add() function with two parameter
function add($x,$y)
{
$sum=$x+$y;
echo "Sum = $sum <br><br>";
}
//sub() function with two parameter
function sub($x,$y)
{
$sub=$x-$y;
echo "Diff = $sub <br><br>";
}
//call function, get two argument through input box and click on add or sub button
if(isset($_POST['add']))
{
//call add() function
add($_POST['first'],$_POST['second']);
}
if(isset($_POST['sub']))
{
//call add() function
sub($_POST['first'],$_POST['second']);
}
?>
<form method="post">
Enter first number: <input type="number" name="first"/><br><br>
Enter second number: <input type="number" name="second"/><br><br>
<input type="submit" name="add" value="ADDITION"/>
<input type="submit" name="sub" value="SUBTRACTION"/>
</form>
Output: 
We passed the following number, 
Now clicking on ADDITION button, we get the following output. 
Now clicking on SUBTRACTION button, we get the following output.
