The encode_entities() should be enough. That is if you insert the value into places like <p>HERE</p> or <input type="text" value="HERE">. If on the other hand you use it in <script>alert('HERE');</script> it's escaped wrong. Likewise in this case: <a href="page.pl?value=HERE"> or just <a href="HERE">.

Ad Update1: There should not be, but there had been errors in web servers that allowed things like this. It's safer to store the credentials in a different file outside the directories accessible by HTTP.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
