I’m trying to extract from a string like this: $message = #porrabarça per avui

  • 0

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:]]+/
