I think you missed the point. SVG is just text. ... There's no need for SVG support per se, as SimpleXML provides all you need anyway. I did miss the point - thanks for setting me straight. However, I'm still unsure about using SVGs. On the one hand, what I'm using as source files are originally in SVG format and I want to be able to dynamically resize and scale them without loss of clarity. That sounds like an excellent reason to use SVG for your image manipulation. But, after they have been resized and scaled, then I think I need to send the resulting image to the browser in some raster image format. Indications are that SVG support on browsers is still not as uniform as PNG or other raster graphics formats. Yeah, Firefox is the only browser I know of with native SVG support worth a damn. Konqueror keeps talking about it but I don't know if it's any good yet. Not sure about Opera or Safari. IE requires a plugin from Adobe, which the last time I was playing with it (which has been a while, but there were no signs of plans to improve it at the time) was OK, but not great and embedded a la flash in a fixed, immutable box. At that last step, assuming that I have manipulated the images to my satisfaction with SimpleXML, can I then output the result in PNG or JPG with PHP? With native PHP, I don't believe so. However, I know that there are assorted command line tools and Java tools to do so. I naturally can't think of them off the top of my head, but I know they exist. You could exec() out to them to cache the rasterized combined image to disk and then serve that. I don't know off hand if there's a PECL module or some user-space PHP code to do that. It's worth spending 10 min Googling it, though. I'm not so sure this can be done. The tricky part is that I am building PHP scripts that could be deployed on servers with different PHP settings, so I'm not confident that I can rely on PEAR or ImageMagick functions being present. Are they standard on PHP 5? Now that could be a problem. You'd have to find either some PHP user-space library or a CLI C library that you could bundle with the app. I'm fairly certain nothing like that is in stock PHP 5. As for finding a good such library, as I said Google would know better than I. (Or maybe I should say Yahoo, since they use PHP. g) Forgive me if my questions are clueless to the point of making the questions unclear. They make a lot more sense now, actually. :-) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson ---End Message--- ---BeginMessage--- Does anyone know of an image gallery I can use on multiple pages of a website.

Now, your problem is exactly as you stated: you don't get the data in the expected format. getenv (REMOTE_HOST) is NOT the referrer. Furthermore, the referrer (which I don't recall what it is sent as exactly, as 'REFERER' I guess (usually gotten via $_SERVER or $_ENV, but getenv() should also work)) is not 'just' the domain name but also includes the path, so you have a huge chance that it won't be exactly what you expect it to be. Parse the url (parse_url() is your friend), extract the host and match against that. - Tul -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Maybe this is what you want... take a look (in a syntax highlighting PHP
editor):
?php
$hash = $_GET['hash'];
require_once('db.class.php');
$db = new db_class;
$db-connect();
/*
You should have an escape method in the db class, otherwise take a look
at mysql_real_escape_string - for MySQL
Also, beware of magic quotes if they are enabled they can mess things
up (not in this case,
but as a general hint).
I usually put things like these in an .htaccess file.
Here's a sample, for a site under construction:
php_flag short_open_tag on
php_flag register_globals off
php_flag magic_quotes_gpc off
php_flag magic_quotes_runtime off
php_flag magic_quotes_sybase off
# Switch to off in production stage
php_flag display_errors on
php_value error_reporting 2039
# This setting depends on you requirements
php_value max_execution_time 300
*/
$safeHash = $db-escape($hash);
/*
If your db class doesn't have an escape method you can do
$safeHash = mysql_real_escape_string($hash);
*/
$r = $db-select(SELECT duration, label, website FROM hhcu_codonations where
hash = '$safeHash' AND valid = '1');
while ($row=$db-get_row($r)) {
// found record - lets see if we can display the image and which image
extract ($row);
$now = time();
if ($duration = $now) {
/*
The call on this is as follows;
img
src=http://mydev.co.za/myscript.php?hash=ARBHASHCODE; border='0'
*/
$referer = $_SERVER['HTTP_REFERER'];
$params = parse_url($referer);
// Beware of gotchas if the referer has no www in the host
param
// We'll add www. to the host if it's not there
$host = (substr($params['host'], 0, 4) == 'www.') ?
$params['host'] : 'www.'.$params['host'];
// Now $host holds something like www.subscribersite.com
$refererWebsite = $params['scheme'].'://'.$host.'/';
/*
So now, the referer is the expected referer or not
You don't need to use MD5 here, you've already checked
the hash
when you queried the DB. You now need to check that the
referer is right for the supplied hash
I'm assuming here you are only hashing the website's
url. You would only need to check the hash
against the request headers if you use a more complex
hashing strategy like the following
define('HASH_SALT', 'a secret string');
$websiteUrl = 'http://www.subscribersite.com/';
$websiteIP = '60.50.40.30';
$hashToStoreInDB =
md5($websiteUrl.$websiteIP.HASH_SALT);
But if you use such a method, you wouldn't need to
check the referer either, you'd build a tentative
hash out of the $_SERVER parameters (HTTP_REFERER,
REMOTE_ADDR) and the HASH_SALT constant,
match that tentative hash against the supplied hash
($_GET['hash']), and then look up that hash
in the database if both hashes match... that would be
all

if ($refererWebsite == $website) {
switch ($label) {
// ... code to follow

Hey Jochem all, Thanks much for this tip. I will check it out. A little further reading looks like PEAR provides some XML and DTD capabilities? Anyone have any experience with this? Also, the reason I asked about the DTD is that these XML files are really extensive, providing lots of varied info about literature, history, a whole ton of topics, so I thought parsing the DTD will be necessary to know what kinds of data I'm really looking at. I'll check out Jochem's suggestion now, but would also like to hear if anyone has used PEAR, and also about the need for the DTD for big, complicated XML files.

So far I've found this: http://us.php.net/manual/en/ref.xml.php Which has some samples on, but nothing that I see will take a DTD file and parse the XML accordingly. use php5 and the DOM extension (not XML and not DOMXML): http://us.php.net/manual/en/ref.dom.php I'm thinking something like this is probably possible. I'm still looking through the docs, but if anyone can point me in the right direction would be appreciated. Thanks!

If you only need to know what kind of data you are looking at, you can just grab the doctype property for the DocumentElement and compare it to a set of (known by you) predefined doctypes... After that, you can implement a walk through the elements of the XML stream knowing what you can expect about it. This will simplify your programming logic, unless there are infinite doctypes for the data source in question. For validation, you can use this http://us.php.net/manual/en/function.dom-domdocument-validate.php (only if you are interested in the document being well formed according to the DTD) For identifying the DTD, check the DocumentElement doctype property and the DOMDocumentType class http://us.php.net/manual/en/ref.dom.php.

Re: [PHP] Question about urlencode....
Unless your URL is more complicated than your example, you shouldn't need to use urlencode() at all. You'd need to use it in a case where your string may contain characters that aren't valid in URLs like spaces and such: $baseurl = http://www.somesearchsite.com/search=;; $searchfor = Grace O'Mally; $searchurl = $baseurl . urlencode($searchfor); Since you set your URL explicitly and it's not something entered by a user, you shouldn't need it. Try that and see if it fixes your other problem with double encoding.. or at least gives a better clue as to where it's coming from. Slainte! -TG - Original Message - From: Colin Guthrie [EMAIL PROTECTED] To: php-general@lists.php.net Date: Thu, 22 Nov 2007 16:19:18 + Subject: [PHP] Question about urlencode Hi, OK this one is a little embarrasing. I've been doing this for years and I just wonder if I'm wrong Say you have an exit link on your site, e.g. /leave.php, which accepts a url get arg. You use this page to record stats/whatever and then issue a Location: header to take the user to the correct location. Fairly standard yeah? Well I've been doing something like: $url = 'http://colin.guthr.ie/'; echo 'a href=/leave.php?url='.urlencode($url).'Click/a'; The logic in /leave.php does not need to call urldecode as it's done automatically by PHP. This has worked well for me in the browsers I've used (IE, FF etc.) Recently, though, when using google webmaster tools I noticed that I was getting a lot of 404's and this ultimately stemmed from the double urlencoding of these url paramaters whereby the % signs used to encode characters like / as %2F were encoded themselves leading to %252F. PHP would automatically urldecode this to %2F but that still leaves me with an encoded variable. Ugg. So my question is, is the google bot just getting it wrong? Is it reading the link and seeing a % and encoding it? Or is it finding a page somewhere randomly on the interweb which has incorrectly double encoded it and going from there? It doesn't give you an referrer info which makes tracking down such errors pretty tricky :( I could just call urldecode manually, but I'm curious as to why I should need to. Anyone fought with this before? Col -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Page not displayed/Forbidden on PHP forms
I would check the follwing: - If the problematic host has apache's mod_security enabled. The system administrator can tell you if mod_security is disallowing some of the input (which might cause the 403 forbidden). - PHP.INI parameters max_execution_time, max_input_time and max_input_nesting_level (more info is at the online php manual) you can query these values through ini_get, and you can set them through .htaccess files, e.g. php_value max_execution_time 300 (if the hosting company allows their use). - Call ignore_user_abort at the top of the processing script (CAREFULLY read the notes for that function) and query the value returned by connection_status, or connection_aborted (maybe create a log file for the returnded values through successive requests to keep track of any issue) - Check what (cache) headers the server or your processing script is sending to the browser. - Also, if $_REQUEST processing is a time consuming operation and you use ob_start, ob_end_flush, etc you can try flushing the output buffer from time to time (if your programming logic allows for that). Well, this is quite a list... but if they are getting 403 forbidden it might be an issue with the server configuration (such as a highly restricted mod_security configuration), rather than server performance or speed. Hope that helps. Ohh, by the way, if you can send the culprit URL to us for testing it will help a lot (BUT DON'T DO THAT if this is a private system, or a system for which you don't want to get any additional traffic).
