( #3333=superdoc: print w/replies, xml ) Need Help??

Your question has been answered directly by the other fine monks, but I thought it would also be useful to point out that this is a common case where a hash is used instead of an array. Hashes make checks for existence much faster than iterating through your array each time (which is what grep does).

Here's an example of how you could make your array into a hash:

my %ignore; @ignore{ @ignore } = (); # note this is a hash slice. the first @ignor +e # is referring to the hash

And here's how you can check the hash for existence:

if (exists $ignore{$username} or exists $ignore{$askname}) {

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
