I see that some people are using rtrim() in their version_compare() alternatives to remove a
trailing '.0'. This is not recommended because rtrim() does not just remove '.0'
and instead removes each character.
Take this for example:
<?php
// Returns '1.1'
echo rtrim('1.10', '.0');
?>
Instead, you should use something like substr() to remove it:
<?php
// Returns '1.10'
$ver = '1.10';
if (substr($ver, -2) == '.0') $actual_version = substr($ver, 0, -2);
else $actual_version = $ver;
echo $actual_version;
?>
