Using basic functions inside PHP

Question

I'm a complete newbie, so sorry if I say this, this is confusing. I am currently working on my online computer science course, and we practice the features. We have to make three sentences to output three different variables inside the sentence

x - y years and has z

Here is what I mean:

Obama is 50 years old and the president of the United States .

Bill Gates is 60 years old and the founder of Microsoft .

Jacob is 20 years old and a student .

This is the code I have:

<?php

function displayStory($name) {
} 
function displayAge($age) {
} 
function displayJob($job) {
    echo $name . " is " . $age . " and is " . $job . ".<br />";
}
displayStory("Obama");
displayAge("50");
displayJob("the President of The United States");
displayStory("Bill Gates");
displayAge("60");
displayJob("the founder of Microsoft");
displayStory("Jacob");
displayAge("20");
displayJob("a student");

?>

I am sure there is an easier way to complete this, and I know other ways to complete this, but we must use the DisplayX function to do this.

Thanks in advance:)
