<?php $firstName = 'Tony'; $lastName = 'Stark'; $jobTitle = 'CEO of Stark Industries'; $qualification = 'MSc in electrical engineering and physics'; echo ' <p>Name: ' . $firstName . ' ' .' is ' . $jobTitle . ' </p>; echo ' <p>Education: He holds a ' . $qualification . ' .</p>; ?>
Your strings are missing some of the matching quotes.
It is simpler to put php variables inside of double-quoted strings -
echo "<p>Name: $firstName, is $jobTitle.</p>"; echo "<p>Education: He holds a $qualification.</p>";
