To simple receive a major PHP version value (e.g., 5.2), you can use next:
<?php
// Output below will looks like '5.2', depends to your version
echo floatval(phpversion());
?>

In a addition to phpversion,..

if you've got a system like ubuntu or some else, you get
<?php
echo phpversion(); // 5.2.4-2ubuntu5.2
?>

To fix this, use the following:
<?php
echo substr(phpversion(),0,strpos(phpversion(), '-'));
?>
