    Can't seem to create a simple pattern matching function due to character than won't allow me to escape it.

    Hi everyone. I am looking to create a simple function that will spot a
    hexcolor in a font tag, that has quotes, and remove the quotes. i.e
    <font color="ffffff"s hould become <font color=ffffff>.

    Perhaps I am making it more complex than it needs to be, but I have
    broken down the input string into an array of single characters using
    preg_split(), and I am iterating through the chars, looking for a quote
    followed by a hash. The problem appear to be with the hash. Although it
    prints out fine, not amount of escaping the hash seems to allow me to
    match it. Instead preg_match() match spaces (obviously because the
    veriable I am using to store the '#', is not storing it properly.

    Please could someone put me out of my misery by either hinting towards
    a simpler way to do it, or just shooting me?

    I am sure there are at least 100 different ways of using regex to
    achieve what I want, but I can't think how. Perhaps I am just looking
    at the wrong functions?

    Many thanks.

    Daz.

      Why not just preg_replace('/(<font\s+color\ s*=\s*)"(#[0-9a-f]+)"/si',
      '\1\2', $html)?

          Because I forgot how to get the matched text from the regex pattern
          match. Hehe.

          Many thanks for that. :)
