Take note that if you pass phpversion() with an empty string, eg.
<?php
echo phpversion('');
?>
It will not return anything, since it cannot find an extension with the name string(0) ''.

to realize if the actual version ist newer than '5.2.10'
simply use:
<?php
if (strnatcmp(phpversion(),'5.2.10') >= 0)
{
# equal or newer
}
else
{
# not sufficiant
}
?>

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(), '-'));
?>
