I'm trying to extract from a string like this:
$message = #porrabarça per avui @RTorq el @FCBar guanyarà per 3-1 al AC Milan
The '3-1'. As Number - Number
I've tried
$message = preg_replace('/[0-9]\s*-\s[0-9]/i', '', $message);
But it isnt working. It's output is the same as the input.
Can you help me out?
The problem is \s here.
/[0-9]\s*-\s[0-9]/
^

+--- This makes a single space mandatory.
You need \s* there. Use preg_match to extract anything. preg_match matches and optionally set the match to a variable. From there you can extract the matches. preg_replace replaces the matched content.
preg_match("/\d+\s*-\s*\d+/", $message, $match);
$num = $match[0];
To replace use this pattern and empty string as replace string in preg_replace.
A better pattern would using POSIX character classes. it'll match any type digit characters of any other locale.
/[[:digit:]]+[[:space:]]*-[[:space:]]*[[:digit:]]+/
If you want to replace the string :
<?php
$message="#porrabarça per avui @RTorq el @FCBar guanyarà per 3-1 al AC Milan";
echo $message = preg_replace('/[0-9]+-[0-9]+/', '', $message);
?>
If you want to get matched groups :
<?php
$message="#porrabarça per avui @RTorq el @FCBar guanyarà per 3-1 al AC Milan";
preg_match_all('/[0-9]+-[0-9]+/', $message, $matches);
print_r($matches);
?>
/i is not needed here. Digits has no case-sensivity
