This is a small example of the ‘bad’ form of variable naming. What’s bad about it is the fact when you read the code: echo “This $a $b is a $c <br>“; it is all but impossible to guess which variable is which. Contrast this with the ‘good form’ variables, which is much easier to read.
[php]
<html>
<body>
<h1>Variables</h1>
<?php
echo "<br>";
$a="Ford";
$b="Explorer";
$c = 2003;
echo "This $a $b is a $c <br>";
?>
</body>
</html>
[/php]
Should produce the following output
[box] Variables
This Ford Explorer is a 2003
