PHP custom regex in url

Question

I am new in Stackoverflow and I have a simple question: I need to create a regex to match a custom patterns in string. I want to create a regex to detect this url:

/post-title-92581_1.html

where $match[0] = 92581 and $match[1] = 1

I created this regex ((\-[0-9]+)_([1-2]{1}).html) works fine,but this returns:

$match[0] // -92581
$match[1] // 1

if i change string to /post-title-925-81_1.html i get

$match[0] // -81
$match[1] // 1

I only want to get the FIRST MATCH (-925) without "-".

Answer 1

Put the - outside of the brackets...

-([0-9]+)_([1-2]{1}).html

Everything inside the brackets gets returned as a match!
