Take a look at the Firebug addon for Firefox and another addon called
"FirePHP" or "FireConsole" (the new name coming soon). It lets you
output PHP debugging data to HTTP headers that show up in your Firebug
console. I believe it supports collapsable tree type output.

I know it's not quite what you want, but what about copying and pasting
the output from the view source to a more advanced text editor like Kate
or Notepad++. They both support code-folding, and allow you to minimise
blocks of code at points in the text, usually where you have opened
brackets, etc. This also comes in handy when you're developing too.

Hello,
I have a function that uses tidy to attempt to clean up a bunch of crappy HTML
that I inherited. In order to use tidy, I write the crappy HTML to a temporary
file on disk, run tidy, and extract and return the clean(er) HTML. The program
itself works fine but with all of the disk access, it runs quite slowly. I saw
on this page (http://www.php.net/manual/en/wrappers.php.php) that I could write
to memory by using php://memory. Unfortunately, I could not quite get it to
work. The problem is that in the below function, the code within the [[[if
(file_exists($dirty_file_path))]]] does not get run if I change
[[[$dirty_file_path]]] to "php://memory". Has anyone ever successfully used
php://memory before? If so, what can I do to use it in my code? Thank you.
//==========================================================
function cleanUpHtml($dirty_html, $enclose_text=true) {

why read from disk in the first place?

what does it matter that it runs slowly, run it once and be done with it?
alternatively use the php tidy extension and avoid the file system and shelling
out altogether.
actually I'd imagine shelling out from a webserver process is the bottle neck
and not saving/reading
from the file system.
lastly I don't suppose you've heard of /dev/shm ?
and, er, no, I don't have experience with php://memory but you might try
searching for
other people's code:

No, but I was intrigued to try it, so I tested this:
$text = 'Some text.';
file_put_contents('php://memory', $text);
echo file_get_contents('php://memory');
And it returned nothing. The docs suck on this and it apparently
doesn't work. I see others use it with fopen(), but there is no mention
of which file functions it works with and which it doesn't.

I did a sample test from the manual with fopen like this,
<?php
$fp = fopen('php://memory', 'r+');
if ($fp)
{
fputs($fp, "line 1\n");
}
rewind($fp);
echo stream_get_contents($fp);
?>
console output
F:\wc\trunk>php -f m.php
line 1

So maybe it only works with an open file/stream resource? Hard to tell
with no docs.

Shawn, would you take a few moments to submit this as a bug at
http://bugs.php.net/? I know you well enough that, if you say the docs suck,
they probably do.

Thank you, this looks like exactly what I need. Unfortunately I cannot get it
to work on my machine. I recompiled PHP with --with-tidy=/usr/local and this
is the version and modules in use:

[snip]
So I figured it out... I was using the wrong command to compile libtidy. (I am
not a *nix geek so I had no idea I was messing it up.) To get it working, I
followed the instructions I found here:
http://www.php.net/manual/en/ref.tidy.php#64281
My setup is slightly different from the person who wrote the directions in that
I am running OS X 10.6.2 and PHP 5.2.12. However, the only difference between
the instructions I followed and what I actually had to do is that the line to
comment out for me was line 525 instead of 508. (The actual line is: typedef
unsigned long ulong;)
Thank you everyone for your help!

Quite easy to do with some CSS.
<a href="#" class="details">
regular content
<div class="details">hidden until mouse overed</div>
</a>
And the CSS would be something like:
a.details
{
position: relative;
}
a.details div.details
{
position: absolute;
top: 0px;
left: 0px;
display: none;
}
a:hover div.details
{
display: block;
}
This is a simplified example, but works without Javascript, and if the
browser doesn't support CSS, the hidden details are just displayed
normally, which is the best fail method I think.
Thanks,

Hi, I've always thought that session data was subdomain specific and would
not carry over between http://www.mydomain.com and
https://secure.mydomain.com, but it seems to be working for me now. Can I
rely on this and post from http://www.mydomain.com to
https://secure.mydomain.com and simply pass a hidden input containing
PHPSESSID, or do I need to pass each key=>value pair that _SESSION contains
at www. and reset them as _SESSION vars at secure.
<https://secure.mydomain.com> ?

1. cookies are shared automatically on SUB domains, so if you set your cookie
domain
to example.com it will be available at both www.example.com and
secure.example.com
2. cookies can have a HTTPS flag set which means they will not be shared with
non-HTTPS
connections.
3. DONT put the contents of $_SESSION on the wire. (given the question you're
asking I'd
hazard a guess you don't have the skills to sufficiently
4. google/read/search/learn about the security implications of sharing a cookie
between
HTTPS and non-HTTPS domains.
5. session_regenerate_id() - I would use this if you intend to pass session ids
around,
although it will probably give you a stack of problems in terms of usability
(e.g. back button usage),
actually I'd use it any time you log someone in or out or have a user perform a
particularly
sensitive action.
6. the $_SESSION will only be available on both sites if they are both on the
same server
and running with the same session ini settings (i.e. session save path, session
name) - different
servers could obviously be using a shared filesystem or an alternative session
storage (e.g.
memcached or database server).
7. consider not sharing the session - instead pass just the data that you need
(e.g. shopping
basket contents etc) and either including a hash of the data (which uses a
secret string that
is not included in the form/url/etc but that both servers/sites know about
AND/OR using 2-way
public key encryption on the data that you pass in between the servers/sites
personally for higher end commercial sites I prefer to just to put everything
on HTTPS
solving all potential issues with sharing a cookie or data between nonHTTPS and
HTTPS sites,
and everything directly related ... the cost being extra overhead per request -
but hardware
is cheap and security is difficult to get exactly right.
the biggest names on the web have [had] security loophopes/problems related to
these issues, and they
generally have tons of man power and some very clever/knowledgable people on
their teams - which is to say:
your chance (and mine for that matter) of not making any mistakes on this front
are slimmer than theirs.

Ohhh? The index page of the manual has 110 lines of totally meaningless
entries, and the
introduction doesn't open. I haven't the faintest idea what it's all about, but
I very
much doubt if it would mean anything to the original writer.

I've never used DomDoument to create an HTML page, and I probably never
will. I also don't have much of a problem with creating decent html code
that validates either.

I don't think heredocs is relevant. The original writer wanted to save the HTML
output of
a working page to a file, whereas (I think!) heredocs are involved with getting
messy
stuff into PHP.
I still think that simply capturing the page from the browser is the simplest
solution for
the original question, but if you want a more elegant one see:
http://codeutopia.net/blog/2007/10/03/how-to-easily-redirect-php-output-to-a-file/
The writer appears to know what he's talking about, and I am pleased to have
found this,
as I have often wanted to to redirect PHP output to a file.

Thanks for this. I was just revising a bit of code to insert some extra
entries into an
array. Previously I had opened a new array, copied the data up to the insertion
point into
it, put in the new entry, then copied the tail, then renamed the new array.
After reading
this, I realise the correct procedure was to copy the existing data into a
temporary
array, insert the new entry in the existing array, and then copy the tail from
the copy
back into the working data.
This way only the data in the tail actually has to be copied, rather than the
whole array.

I do not use nor recommend Windows for delivering messages to many
recipients, but if you are stuck with it, maybe you can use Microsoft
Exchange in the same machine where PHP is running, you can drop the
messages in the mail queue pickup directory to avoid waiting for the
mail server to process them.

Hello,
When uploading a file the variable $_FILES['userfile']['tmp_name'] is not
set and when debugging I get the following error although /tmp folder exists
and the permissions are set to 777:
$_FILES['userfile']['error'] = 6
which says
UPLOAD_ERR_NO_TMP_DIR
Value: 6; Missing a temporary folder. Introduced in PHP 4.3.10 and PHP
5.0.3.
Has anyone encountered such a problem or has a clue as to what the cause
could be?
Thank you.
Kind regards
Ali

What does "print phpinfo()"; tell you about the upload_tmp_dir?
