Basically every "array" in PHP is an array and a hash, glued together. All of the values are stored in the hash as key/value pairs, but there's an array stored along with it that gives an ordering to the keys. The thing is, most of the time you either need one behavior (in-order processing) or the other (random lookup), and not both. PHP is giving you the overhead of both at all times; Perl is requiring you to say which one you really want. In the case where you really do need both methods, it's not very hard to set up the necessary parallel data structure in your own code, but Tie::IxHash is another option.

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).
