PHP Parameterized Function
PHP 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
//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);
?>
Output
Sum of two numbers is = 1410
Differenceof two number is = 467
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']);
}
?>
