PHP Parameterized Function


PHP Parameterized Functions are the PHP functions with parameters. PHP Parameterized functions are a piece of code that can be used repeatedly in a PHP program. Any number of parameters can be passed inside a parameterized function after the name of the function, inside the parentheses.

Syntax:

function functionName() 
{
    code to be executed;
}

Example 1: Parameterized Function used with a single argument

<!DOCTYPE html>
<html>
<body>
 
<?php
function website($languagename) {
	echo "$languagename.<br>";
}
 
website("PHP");
website("Jquery");
website("HTML");
website("Javascript");
?>
 
</body>
</html>

Output

PHP.
Jquery.
HTML.
Javascript.

Example 2: Parameterized function used for ADDITION (Two arguments passed; function returns a value)

<!DOCTYPE html>
<html>
<body>
 
<?php
function sum($x, $y) {
	$z = $x + $y;
	return $z;
}
 
echo "Sum of 4575 and 1890 = " . sum(4575,1890) . "<br>";
echo "Sum of 5677 and 1783 = " . sum(5677,1783) . "<br>";
echo "Sum of 268879 and 49879080 = " . sum(268879,49879080);
?>
 
</body>
</html>
