为linkify-php函数修复正则表达式中的括号

我已经在我们的OSticket系统上实现了"linkify"，它似乎运行得很好，除了一个我在文档中没有注意到的缺陷http://jmrware.com/articles/2010/linkifyurl/linkify.php.当连杆后面跟着a）时，它包括连杆中的）。GRRR

所以我想知道是否有任何超级regex的家伙可以调试，因为linkify已经几年没有更新了。。。

如果需要，这里是正则表达式：

 $url_pattern = '/# Rev:20100913_0900 github.com'/jmrware'/LinkifyURL
    # Match http & ftp URL that is not already linkified.
      # Alternative 1: URL delimited by (parentheses).
      ('()                     # $1  "(" start delimiter.
      ((?:ht|f)tps?:'/'/[a-z0-9'-._~!$&''()*+,;=:'/?#[']@%]+)  # $2: URL.
      ('))                     # $3: ")" end delimiter.
    | # Alternative 2: URL delimited by [square brackets].
      ('[)                     # $4: "[" start delimiter.
      ((?:ht|f)tps?:'/'/[a-z0-9'-._~!$&''()*+,;=:'/?#[']@%]+)  # $5: URL.
      ('])                     # $6: "]" end delimiter.
    | # Alternative 3: URL delimited by {curly braces}.
      ('{)                     # $7: "{" start delimiter.
      ((?:ht|f)tps?:'/'/[a-z0-9'-._~!$&''()*+,;=:'/?#[']@%]+)  # $8: URL.
      ('})                     # $9: "}" end delimiter.
    | # Alternative 4: URL delimited by <angle brackets>.
      (<|&(?:lt|'#60|'#x3c);)  # $10: "<" start delimiter (or HTML entity).
      ((?:ht|f)tps?:'/'/[a-z0-9'-._~!$&''()*+,;=:'/?#[']@%]+)  # $11: URL.
      (>|&(?:gt|'#62|'#x3e);)  # $12: ">" end delimiter (or HTML entity).
    | # Alternative 5: URL not delimited by (), [], {} or <>.
      (                        # $13: Prefix proving URL not already linked.
        (?: ^                  # Can be a beginning of line or string, or
        | [^='s''"']]          # a non-"=", non-quote, non-"]", followed by
        ) 's*[''"]?            # optional whitespace and optional quote;
      | [^='s]'s+              # or... a non-equals sign followed by whitespace.
      )                        # End $13. Non-prelinkified-proof prefix.
      ( 'b                     # $14: Other non-delimited URL.
        (?:ht|f)tps?:'/'/      # Required literal http, https, ftp or ftps prefix.
        [a-z0-9'-._~!$''()*+,;=:'/?#[']@%]+ # All URI chars except "&" (normal*).
        (?:                    # Either on a "&" or at the end of URI.
          (?!                  # Allow a "&" char only if not start of an...
            &(?:gt|'#0*62|'#x0*3e);                  # HTML ">" entity, or
          | &(?:amp|apos|quot|'#0*3[49]|'#x0*2[27]); # a [&''"] entity if
            [.!&'',:?;]?        # followed by optional punctuation then
            (?:[^a-z0-9'-._~!$&''()*+,;=:'/?#[']@%]|$)  # a non-URI char or EOS.
          ) &                  # If neg-assertion true, match "&" (special).
          [a-z0-9'-._~!$''()*+,;=:'/?#[']@%]* # More non-& URI chars (normal*).
        )*                     # Unroll-the-loop (special normal*)*.
        [a-z0-9'-_~$()*+='/#[']@%]  # Last char can''t be [.!&'',;:?]
      )                        # End $14. Other non-delimited URL.
    /imx';

我开始摆弄它，但事实证明它有点让我不知所措。我也在寻找其他替代建议，而不是linkify？

如果你注意到倒数第二行：# Last char can''t be [.!&'',;:?]基本上，最好在其中添加一个）？
