Some code samples would be really helpful. You also said "an error occurred"
but failed to mention any details about that error. That aside, I'll make a
guess at some possible problems:

1) You're trying at access the wrong super global (e.g. GET when you should
be looking for POST).
2) You're trying to access the variable directly but do not have
register_globals enabled.
3) You're spelling something wrong (we all do it from time to time).

I'm running PHP version 4.3.0 on a Macintosh PowerBook with OS 10.2.1,
doing some PHP tutorial exercises. And I've run across something I haven't
seen before in the sample code I'm seeing:

   print <<<HERE
   [multiple lines of code]
   HERE;

Now, from what I've read, it seems that the point of "<<<HERE ... HERE;" is
to execute all the code between the two "HEREs".

But when I run this thru my browsers--Netscape 7.02 and IE 5.2--I get the
following error message:

   Parse error: parse error, unexpected $ in [path to file] [line number]

Is this "<<<HERE ... HERE;" new to PHP sometime after version 4.3.0, and
I'm just out of luck unless I upgrade?

Thank you.

AFAIK, it has been in PHP since the beginning of PHP4. I could be wrong,
but I think it was one of the new features added when 4.0 came out. Here
is a little reference material for you on it.

http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

Without seeing a code snippet, I can't tell you what your doing wrong.
Probably something simple, but hopefully the document above will help
you. Another resource which gives a decent guide to HEREDOC's is the
fairly new book "Core PHP Programming Third Edition". It's been a while
since I read it, but if memory serves it has atleast a page or two on
it's usage. I also highly recommend that book anyway to any PHP
programmer, beginner all the way to highly advanced. I thought I knew
almost everything about PHP and even I still learned about a new
function or two from the book. Very worthwhile.

attached mail follows:

It doesn't execute the code between the <<<HERE ... HERE. It's called
heredoc syntax for delimiting strings.

Say you had a really long string, with lots of variables in it that
needed parsing, and lots of " and ' signs. Instead of using print "" you
can use the heredoc syntax. You start with <<< and an identifier (in
this case 'HERE') and then end with that identifier and a semicolon.
It's just a way for delimiting strings, so you need to look for what's
causing that unexpected $ just as if you were looking at a "" string. I
can't help you any more without a code snippet.

$_SESSION is an array, therefore its elements are indexed like so:
$_SESSION['timestamp'].

You can place <form> tags around the anchors and use hidden tags and send
via post so the variable is not obvious. A user reading the source would
see this though...

echo "<form name=\"form1\" action=\"https://this.site.com/somePage.php\"
method=\"post\">\n";
echo "<a onClick=\"this.form.submit();\">SomeLinkText</a>\n";
echo "<input type=\"hidden\" name=\"variable\" value=\"".$value."\">\n";
echo "</form>\n";

I'm not sure off the top of my head if the anchor tag must have any other
description. You might be able to use onChange instead of onClick to
include selection by using the keyboard, but I'm not sure if the anchor tag
responds to onChange. You'd have to try it out.

I doubt it- otherwise it would be pretty easy to set, say
$_SESSION['logged_in']

But you /can/ use JS to set a cookie, which can be retrieved (and stored in
a
session variable if you want) by PHP.

Evan,

Thank you for responding - as a newbie to PHP, HTML, and JavaScript, the
cookie approach is a little too complex for me. However, after googling
some more, I came across the following approach which seems to be simple
and works well:
(a) enclose the result table within a form, specifying the form name as
"results", the "post" method, and "action" as the page url to be loaded
when the anchor is clicked.
(b) insert a hidden field ("seqnum") within the form.
(c) In the php code which builds the table, for the anchor link, use the
following code: ($seqno is the data to be passed)
                            print "<a href=\"javascript://\"
onclick=\"document.results.seqnum.value=$seqno;document.results.submit();\">";
Result: $HTTP_POST_VARS['seqnum'] will be set to the sequence number.
The only downside to this method seems to be that the "visited" anchors
do not change color. Can anyone suggest how to fix that?

Peter

A few months back the official PHP website still warned againts PHP and
Apache 2. I am wondering about the current status of these two technologies
when used together. I am about to configure a web server and was going to
use Apache 1.3 with PHP4+ as opposed to Apache 2 with PHP4+. What are your
opinions, thoughts and experiences.

Thanks in advance.
