I have the following string: a:2:{s:4:"user";b:1;s:6:"userid";s:2:"48";}
What I need to do is extract number 48 from it, in this case. This number could have any number of digits. How would I go about doing this?

It looks like you are facing a serialized strings. So, instead of trying to get that number using regular expression or any other string manipulation methods, try this:
$myVar = unserialize('a:2:{s:4:"user";b:1;s:6:"userid";s:2:"48";}');
$myNumber = $myVar['userid'];

What exactly are you trying to achieve? That string looks like a serialize()d one, so your best bet would be to unserialize() it

It looks like serialized string.
$data = unserialize('a:2:{s:4:"user";b:1;s:6:"userid";s:2:"48";}');
print_r($data['userid']);

Looks like that's a serialized associative array. You just need to use unserialize() to turn it back from a string into an array.
<?php
$arr = unserialize('a:2:{s:4:"user";b:1;s:6:"userid";s:2:"48";}');
echo $arr['userid'];
?>

The string I see is serialized array in PHP
To unserialize array do this
$obj = unserialize('a:2:{s:4:"user";b:1;s:6:"userid";s:2:"48";}');
echo $obj['userid'];
I have unserialized array then access array param by name
