I have a specific need to strip characters from a PHP input.

For example, we have a version number and I only need the last part of it.

Given 14.1.2.123 I only need 123
Given 14.3.21 I only need the 21

Is there a way that I can get just those numbers in PHP?

You can try this - 

$temp = explode('.', $version); // explode by (.)
echo $temp[count($temp) - 1]; // get the last element

echo end($temp);

Or

$pos = strrpos($version, '.'); // Get the last (.)'s position
echo substr(
     $version, 
     ($pos + 1), // +1 to get the next position
     (strlen($version) - $pos) // the length to be extracted
); // Extract the part

strrpos(), substr(), strlen(), explode()
