Question

So as far as I know, I have done this exactly as prescribed I should do, but PCRE makes absolutely no sense to me at all, so I am going to ask you what is wrong with this code and why does it say:

missing terminating ] for character class at offset 10 in

  $UrlTeams = preg_replace(
    array(
        "/[\/\\\40][\\]?/",
        "/[\.%]/",
        "/\&/"
    ),
    array(
        "/\-/",
        "",
        "\&amp\;"
    ),
    $UrlTeams
  );

Answer 1

Try:

$UrlTeams = preg_replace(
    array(
        "#[/\40\\\\][\\\\]?#",
        "#[.%]#",
        "#[&]#"
    ),
    array(
        "-",
        "",
        "&"
    ),
    $UrlTeams
  );
