PHP Regular expressions not working

Question

I've been using regexr.com to build and test regular expressions to use in my php programs. However, with this one particular expression, it seems to work on the website but not in the program and I am not sure why

I am trying to match EU label data (ex: GC 71) in the following string:

"Viking SnowTech II 165/70 R13 79T Winterreifen Auf Lager  G C 71  dBKundenbewertung (2.00) 29,50 € Details  In den Einkaufswagen"

the regular expression '#\\s\\w\\s\\w\\s\\d{1,}#' works fine on regexr.com but finds no match in my program

$eulab = $row_html -> plaintext;
        if( preg_match('#\s\w\s\w\s\d{1,}#', $eulab)){
            $insert['eulab'] =  $matches[0];

        }else {
            echo "No Match";
        }

i've tried other expressions too like \\s{1}[AZ]{1}\\s{1}[AZ]{1}\\s{1}\\d{1,}\\s{1} which also work on regexr but find no match in my program. Could this be an encoding issue? or just my php syntax? No errors are being thrown.

Answer 1

My problem was that the browser was only displaying a single whitespace when really there was more than that. I altered the expression to correct for that and it worked.

problem solved by @chris85 above

My final code and expression are:

        $eulab = $row_html -> plaintext;

        if( preg_match('#\s\w\s+\w\s+\d+#', $eulab, $matches)){

            $insert['eulab'] =  str_replace(" ", "", $matches[0]);
        }
