Re: [PHP] free allocated memory: HOW ?
Couple of questions come to mind... 1. How big is this template that you're loading? Not sure why almost any HTML file would take up 300+ meg of memory when loaded into a variable. Are you loading images and other content in as well or just the HTML file? 2. Replacing the placeholders with actual data increases memory that much? Damn.. maybe I'm just ignorant of how PHP maintains things in memory, but that seems kind of nuts too 3. Do you have to store each newsletter in memory at each loop or can you send them out then move to the next one without storing them in an array or whatever you're doing? 4. Please tell us these 'newsletters' don't contain information on "male enhancement products" or "govt seized puppies"..hah -TG = = = Original message = = = I am using PHP version 5.1.2. on my dev machine. The same problem with PHP 5.2.1 on webserver. I am generating mails based on a HTML Template. After reading the template with fread() memory_get_usage() says ~386 MB in use...

RE: [PHP] WWE in Stamford, CT needs a kick ass PHP Developer!
Thanks for the insight Tedd. It's good to get real feedback (unlike some of these guys busting my stones here - lol). I can take the blame on putting that Dreamweaver component in there, not our Development team. Gotta remember a lot of times you are dealing with a job spec developed from HR and we don't get the nuances of the space like you folks do. Basically the Dreamweaver is listed there because there is a lot of interdepartmental work that goes on and the less apt employees who are more "Creative" in nature work well in the Dreamweaver application (think Magazine Editors and Photo Departments and such, all of the folks who are more content than anything else). So I need someone who can play both sides, our developers are all excellent and I'd put them up with anyone in terms of ability. So thanks everyone for taking the time to see what World Wrestling Entertainment is all about. I'd really appreciate you keeping us in mind if you hear of anyone who is looking. Thx - Pat -Original Message- From: tedd [mailto:[EMAIL PROTECTED] Bullcrap! If you think that nested tables gets you in the "ballpark" quicker, then you haven't a clue as to what css is used for. My advice, replace your Dreamweaver experience requirement with someone who really knows css and you'll be a lot better off in both reducing time to develop and subsequent compliance issues. IMO, anyone who states that they produce "dynamic and cutting edge web sites" using a WYSIWYG editor is highly suspect and any employer who asks for that experience is doing his business and his clients a disservice.

Re: [PHP] scandir and ftp wrapper
Still can't get it to work, seems to be a problem generally with the ftp
wrapper.
If I try something really basic like
echo file_get_contents('ftp://user:[EMAIL PROTECTED]/file.txt');
I get an empty string with no error messages.
If I copy and paste the ftp url string into firefox it displays the file, so
the url is correct
If I try this
echo file_get_contents('http://www.google.com');
I get the html displayed. I have been testing this code using the php cli if
that makes any difference.
Really could use some suggestions on this one
Thanks

The SESSION_ID that is stored in a cookie on your computer is what links you to your authenticated session on the server. So the owner manages to sniff that SESSION_ID, knowing you are still logged on, he goes to the same site you are on, and edits the cookie that was generated by that site, to have the same SESSION_ID as the one he sniffed over the network. The owner has now owned/hijacked your session and is authenticated as yourself. Depending on the logoff mechanism involved he may or maynot be able to continue using your session when you logoff. So, to conclude on how to optimize your security, your authentication system should be encrypted, as in log in using https:// . Hope this helps, P.S You can try this at home by opening your same siteon two different computers and editing the session cookie on the one your not authenticated on with the session_id from the one you are authenticated on. It's quite suprising how it just "logs in" without credentials ;) Regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] 'lang' file editor ...
what I'm looking for is something that will make it possible for an end user to merge [the contents] existing language files (that contain the items for the same language) *and* perform translations between languages in a visual/easy way (i.e. without opening a text editor) but end up with lang files that still formatted and commented when I'm done. it's a three step process: 1. 'parse' 2 files: a 'reference' and a 'translation' file 2. display an editing interface for the 2 files (textareas, filtering [e.g. show only untranslated items], sorting, etc) 3. write out a merged/updated file. probably the merging of 2 existing lang files of the same language will require a seperate interface than the translation/comparison of 2 files containing different languages. I have made a half-assed attempt to do this some years ago and it worked ok but wasn't quite the level of sophistication I desired - If no one has anything like this lying around then I guess it's time for me to hack up a new thingummy, using var_export()/print_r() [and running the code to merge, etc] won't cut it (I've been down that road already) so probably I'm looking at using either the tokenizer (although how exactly is something I'd have to look into) or a combination of preg_match()/preg_replace() (which is something I am confident I can now do to the required level - when I tried before my regexp skills sucked too much). I'm quite sure I make it work, but I'd be surprised if no-one has gone before me - there must be tons of projects out there with the same kind of language file structure ... maybe I should consider moving my 'shit' into gettext format.

While I've not looked into it myself, I'd imagine it is just a VCALENDAR attachment with the correct (or perhaps M$ bastardised) MIME type. If you have an IMAP server you can use, send the mail to Outlook and drag the message to the IMAP server then use the shell or e.g. Thunderbird to look at the Message Source that Outlook inexplicably keeps so secret and guarded from you!! It should be obvious from that how to copy it (unless it's wrapped up in the evil package of a "winmail.dat" file - eugh TNEF sux s bad) Col. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

"Syntax" is grammar, a set of rules, the "visible" part of a programming language, something you either follow or you get a parse error. To which grammar are you referring? > be it dot notation or the pointers (->) in php. Having "primitive" types, including literals, behave like instances of a class helps writing object-oriented code, because you don't have to special case. It's not required, however. You can write o-o code in today's PHP, it just won't be purely "objective". > I heard it called messaging at one point in the past. > > the passing up of information in the tree.

The class really represents a number, not "Math", that's too abstract
(pun intended) for an instantiable class.
Besides, you're mixing together two responsibilities, Math should really
be called Number, it should be immutable, and you'll spare someone from
a terrible debugging session caused by someone doing
$math = new math;
$ten = $math->in(10);
$five = $ten->subtract(5);
$fifty = $ten->add(40);
($fifty is actually 45, because $ten is 5 after the subtract() call)
