Thanks, --Rick --Rick: The above described rounding algorithm introduces more bias than simply using PHP's round() function, which always rounds down. IMO, modifying rounding is not worth the effort. The best rounding algorithm is to look at the last digit and do this: 0 -- no rounding needed. 1-4 round down. 6-9 round up. In the case of 5, then look to the number that precedes it --

[PHP] htmlMicroscope 1.2.0 out - much better than 1.1.0
Check it out at http://mediabeez.ws/htmlMicroscope
Last modified Mon, 11 Jan 2010, 13:00 UTC+0100
Latest changes:
* Javascript hm() support added
* Added ability to view HTML strings as rendered HTML.
I admit there are still problems with some HTML taking over the
browser as soon as viewed in rendered form.
I hope to fix most of those problems in a later release.
* Added ability to put semi-binary data (see All Ascii in
random array example) in values.
* Much improved CSS; it's now properly generated in javascript
instead of badly hand-crafted stored on the server.
Themes are now generated from definitions like these:
( please use hms.tools.addTheme(contributerName, themeName,
theme) to add a theme, and load them just after hm.js is loaded. var
theme = renesIce)
options : {
..
authorsDefaults : {
themes : {
...
,renesIce : {
themeName : 'renesIce',
cssGeneration : {
colorLevels : {
// This sets stops for color gradients.
// 0 = outer level of display,
// 100 = deepest level of display.
0 : {
background : 'navy',
color : '#FF'
},
45 : {
color : 'black'
},
75 : {
background : 'lime',
color : 'navy'
},
100 : {
background : 'white',
color : 'black'
}
//Rules:
// 1: only css COLOR properties allowed here.
// color names allowed, for a list see
http://www.w3schools.com/css/css_colornames.asp
// 2: properties used anywhere in a list like this must be
present in both 0: and 100:

If you are coming from a windows machine, you can use Cygwin or Xming to set up an X server on the box before SSHing to your data center w/X11 forwarding enabled. -Ken Sande Many thanks to everyone! I currently use a mixture of FreeBSD, Linux, and Solaris/OpenSolaris as operating systems so X11 forwarding is not a problem but maybe quite slow considering the distance between me and my data center right now, and also I have only 1Mbps upstream as the data center uses ADSL which is a restriction on my behalf. Am using SFTP to transfer non-html related stuff and using simple nano or copy-paste from the Gnome terminal. Yeah many options available I know and I guess that's what makes things fun :-) Anyway I'm sure I'll work something out, at worst case I could always VPN once I get a Cisco router out here and get an IPsec tunnel going and do things over NFS mount?? Regards, Kaya I never bother with X-forwarding for development work, it is too slow I agree. I use Konqueror to connect as an FTP client, as it works really well as a file manager with the split screen views it has. From there, I can manage most of my files as I wish over sftp as if they were local. The only thing I can't do it edit the graphics files with Gimp, as that doesn't use KDE's kioslaves :( Thanks, Ash http://www.ashleysheridan.co.uk
RE: [PHP] Upgraded PHP now website doesn't work properly?
From: Kaya Saman I also forgot to mention, it's worth getting an editor that comes with syntax highlighting, as this would have shown you the problem right away. Thanks for both comments Ashley! I will attempt it now. An editor with syntax checking?? Currently my data center is in the UK and I am in Turkey so am having to SSH in and my current text editor is nano. Are there any good CLI based editors that will do highlighting something hopefully not in the vi/vim categories as I really don't get on with them! When working in a shell, I always use joe (Joe's Own Editor). But my first word processor was WordStar, so those keystrokes come naturally.

[PHP] Easy Eclipse PHP Problem
Hi gang: I recently installed MAPA on my new system (Mac X 10.6.2) to use use Eclipse and PHP 5. The EasyEclipse for PHP download is located at: http://www.easyeclipse.org/site/distributions/php.html However, the installation fails. I posted an error report, but there are other reports that date months back. Does anyone have the ear of any developers who work on this open source project?

But what you can do is keep your dev box local, and then use rsync over ssh to publish to the production (or dev) server that is across ocean(s). I use .devel as my TLD for my dev hosts (IE www.something.devel) but otherwise have the dev box configured identical to the production server, so that if it works on dev box I know it works on production. Other thing I do, cron job on production dumps the database once a night, cron job on dev fetches it (via rsync over ssh w/ keys) and applies it to dev database so that the dev database is always very close to production database. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

//$data and $errors could be passed in from the above function if

for simple pages. Its a mini MVC where the code could post the data

Re: [PHP] Upgraded PHP now website doesn't work properly?
But what you can do is keep your dev box local, and then use rsync over ssh to publish to the production (or dev) server that is across ocean(s). I use .devel as my TLD for my dev hosts (IE www.something.devel) but otherwise have the dev box configured identical to the production server, so that if it works on dev box I know it works on production. Other thing I do, cron job on production dumps the database once a night, cron job on dev fetches it (via rsync over ssh w/ keys) and applies it to dev database so that the dev database is always very close to production database. Thanks for the tip! It isn't really a necessity as I'm not a web developer - I just built my site from scratch that's all as I don't have any developer friends who can help me out since I'm not an established company yet.. Usually I just sftp a tar'ed folder or files into my home dir if I need anything or do work on the fly. I really need to learn rsync though as I managed to accomplish transfers of it once but never again :-( It is especially useful for backing up machines!

[PHP] Count the Number of Certain Elements in An Array
Hi, This seems like a pretty simple problem, but I can't seem to be able to figure it out. I have a lot of elements in an array, and some of them are duplicates, but I don't want to delete them because I have other purposes for it. Is it possible for me to find out the number of certain elements in an array? For example, // Create a simple array. $array = array(1, 2, 3, 4, 5, 3,3,4,2); $total = count($array); echo $total; If I run the code, the value of $total would be 9. However, what I really want to do is to get the values of the different instances of each, like: 1 = 1 2 = 2 3 = 3 4= 2 5= 1 Is there a simple code that I use to find this out? Thanks for your help.

LL I do that sort of thing all the time and don't get RBL'd. I think the key things are if your domain can be reverse verified, the frequency you send (if you're just sending hundreds of emails out that's a red flag), BCC: but no TO:, and if the content/body seems to be non-spammy. Make sure any hyperlinks in the body are correct and non-spammy looking too. A common phishing routine is to display one hyperlink to the user, but the actual 'click' takes you somewhere else. I think doing one of those, to register, click _here_ deals is WORSE (from an automated spam filter POV) than showing the actual hyperlink and making it a hyperlink too. Ala, to register, click http://www.abcaccos.org/register/fa4jar4875;. Avoid sending HTML emails for registrations too. It has a better chance of getting through and should have a disclaimer in it to 'whitelist this sender' sort of dealio. Once they're setup, then you can work with HTML emails, but you don't want to loose/frustrate customers right off the bat by not letting them register properly despite how pretty you think the HTML version looks. I think you should [a] do what your client asks -- it's their money [b] put in a From: that is representative of the site the user expected the email to actually come from [c] put a disclaimer on your web form for the person to add ord...@computility.com and eve...@abcaccos.org to their whitelist (no-spam filter) [d] make the SUBJ: line of the email VERY explicit about WHO and WHAT this is concerning: ie SUBJ: Registration Confirmation from ABC Assoc. for username JDOE requested If I was a customer and got an email from @computility.com and I didn't know who the heck they were, since I was expecting from @abcaccos.org, then I would most likely delete it.

IMO, modifying rounding is not worth the effort. The best rounding algorithm is to look at the last digit and do this: 0 -- no rounding needed. 1-4 round down. 6-9 round up. In the case of 5, then look to the number that precedes it -- if it is even, then round up and if it is odd, then round down -- or vise versa, it doesn't make any difference as long as you are consistent. Here are some examples: 122.4 -- round down (122) 122.6 -- round up (123) 122.5 -- round up (123) 123.4 -- round down (123) 123.6 -- round up (124) 123.5 -- round down (123) There are people who claim that there's no difference, or are at odds with this method, but they simply have not investigated the problem sufficiently to see the bias that rounding up/down causes. However, that difference is very insignificant and can only be seen after tens of thousands iterations. PHP's rounding function is quite sufficient. This is called (among other things) banker's rounding. But PHP's round() function won't do banker's rounding, as far as I know. Paul -- Paul M.
