Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You need to double evaluate.
$$errortype resolves to $invalid
evaluating resolves to the string containing $number.
That has to be evaluated as well.

Also why not use foreach and you can use eval()'s
return value. See below:

<?php
$errormessage = "";

$error["1231"] = "invalid";
$error["1255"] = "invalid_max";

$invalid     = 'You did not choose a valid quantity for item number
$item.\n';
$invalid_min = 'You did not order the minimum amount for item
$item.\n';
$invalid_max = 'You ordered more than you were permitted for item
$item.\n';

//while (list($item, $errortype) = each($error)) {
foreach($error as $item=>$errortype) {
        $errormessage .= eval("echo eval(\"echo
\\\"$$errortype\\\";\");");
}

echo $errormessage;
?

$error["1231"] = "invalid";
$error["1255"] = "invalid_max";

$invalid     = 'You did not choose a valid quantity for item number
$item.\n';
$invalid_min = 'You did not order the minimum amount for item
$item.\n';
$invalid_max = 'You ordered more than you were permitted for item
$item.\n';

while (list($item, $errortype) = each($error)) {
    eval("\$errormessage .= \"$$errortype\";");
}

print $errormessage;

Eval prints the following:
You did not choose a valid quantity for item number $item.
You ordered more than you were permitted for item $item.

It should print this:
You did not choose a valid quantity for item number 1231.
You ordered more than you were permitted for item 1255.
