正则表达式只从字符串末尾选择数字

Question

I need a bit of a help with regex, fro example I have these strings:

• "Dovolenka (8)"
• "Bol raz jeden život 26/26"
• "Parížski mohykáni č.1"
• "Vtipnejší vyhráva 1985; Deň tlače,rozhlasu a televízi"

And I need to get the numbers "8", "26", "1", but not the "1985" that's a year not a part number. I got this so far '/(\d+).?$/' that works for picking the number but I do not know how to remove the string for preg_replace() function, so it only returns the wanted numbers.

Edit: What if i wanted only the strings, so vice versa ?

Answer 1

Have a look at preg_match function, the third parameter is the array of matched items, as you enclose your numbers in brackets, you'll find them there. To be more precise, $matches[1] contains mathcing numbers, $matches[0] contains the whole matched expression.
