How to match only numbers after a letter?

Question

I want to match only numbers after s

What I've tried

$line = "sometext s123 text";
preg_match("/s[0-9]*([0-9])/",$line,$match);

echo $match[0]

I'm getting s123 instead of 123

Answer 1

$line = "sometext s123 123";
preg_match("/s(\d+)/",$line,$match);

echo $match[1];

Answer 2

You should capture the numbers in a capture group, and then access group 1 instead of group 0 :

preg_match("/s([0-9]+)/",$line,$match);
echo $match[1]

$match[0] will give you complete match including s .
