It's a learning curve for sure, but once you have one MVC framework in your tool belt, you can pick up others easily.

It must be, because I know you're not that stupid, Richard. If my boss doesn't pay me, it's breach of contract. There's nothing in dispute there. My point was only that when the book was written is irrelevant. It's just as irrelevant as the lag time between your work and your paycheck. No, it is quite relevant. The time spent on the book/program/creative work cannot be gotten back whether you are paid for it or not, therefore that time cannot be stolen from you. There may, however, be a breach of contract involved in either case. It is an important distinction. See below. It's not a semantic game. Copyright infringement is not theft, under the laws of the USA or the laws of physics. To call it such is wrong, inaccurate, misleading, disingenuous, ignorant, and otherwise inappropriate. and a violation of the author's reasonable expectations, Artificially created by the law, yes. And is not the ability to enforce a contract between two people not artificially created by the law as well? One could just as easily argue that all civil law suits, artificial creations by law and not having actual criminal behaviour, should also be thrown out. I never said that artificial laws should all be thrown out. They should, however, be understood in their proper context. A physical object can only be in the possession of one person at a time, per the laws of physics. Property law enhances and structures that natural situation. Information, which includes both ideas and their creative expression, by nature becomes known to anyone it touches without depriving the originator of it. It can be possessed by more than one person simultaneously. Copyright law artificially creates such a restriction on movement in an attempt to make its creation more economically attractive. It is not, however, directly based on physical laws. Note that I am not making a statement about right or wrong about either of the above sorts of laws. I am simply explaining them in proper context, because one cannot make a viable statement about whether they are right or wrong without understanding them in proper context. Speeding while driving is also an artificial law in that regard, as there is no physical law that says a car can only go 30 mph. That doesn't make speeding OK or less illegal, it just means that it is not a natural law. Really people. I find it hard to believe that the otherwise-intelligent people on this list have such a hard time with the concept that something should not be done for reasons that don't involve physical property, just as I find it hard to believe that making up things that someone supposedly said has suddenly become the in thing to do. Your post made it seem that you were in favor of those who choose to infringe on copyright. In every online copyright debate I've gotten into, people always seem to assume that either you're with us or you're with the evil terr'ist pirates. Nothing could be further from the truth, nor further from actual sense. That's why I keep getting into these debates; to point out that it's not a simple copyright is moral and eternal vs. rampant theft and economic downfall question. -- 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 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Symfony versus CakePHP?
Disclaimer: I have not used Zend Framework. What I am about to say is based on a blog entry by someone whose name I forget so I can't go track it down now. :-) CakePHP, Symfony, Drupal, etc. are full stack systems. That is, they provide an integrated structure and you match your development to that structure. That means doing things the system's way makes life quite straightforward, but going against the grain makes life quite difficult. Zend Framework, ezComponents, etc. are component systems. They're more of a collection of robust tools that you can put together your own way to build something without having a structure presented to you already. That means you're not bound by a given structure, but you also don't have a structure to fall back on. Both are appropriate in different situations.

Re: [PHP] PHP Performance and System Load
on the point of class size; i think this is more a design issue than a performance issue. i worked at a place where we had several files w/ classes that were several thousand lines in size. one i remember was over 6000 lines long. personally i would never let something grow that large, but all im saying is we had large classes like that and the system wasnt crawling. -nathan On 7/20/07, Larry Garfield [EMAIL PROTECTED] wrote: On Friday 20 July 2007, Sascha Braun, CEO @ ejackup.com wrote: Dear People, The webserver does only contain the webspace filesystem structure as well as 5 line of PHP Code dummies, for every document in the content management system, to avoid the usage of mod_rewrite. I inherited a CMS at work that did that. Stop. Now. Use mod_rewrite. You'll live longer and spend less on hair-regrowth medication. mod_rewrite is not itself a huge performance hit. If you're on a dedicated server then you can move the mod_rewrite directive to the apache.conf file and disable .htaccess files, which can give you a performance boost, but if a reasonably simple mod_rewrite is the difference that is killing your server then you need to rethink your server. It's a minor issue. You'll get a better performance gain out of a slightly faster processor. Your PHP coding style itself likely has little if any impact on performance. pre vs. post increment is going to be a tiny fraction of a percent compared to the time taken to parse code, hit the database, hit the disk, etc. As others have said, benchmark benchmark benchmark. As a general guideline, the big performance killers I've run in to include: - Parsing. Opcode cache is good, but if you can give it less to cache that helps, too. You said you're already using autoload(), which helps, but make sure that you're not loading gobs of code that you don't use. Even with an opcode cache, that will eat up RAM. - SQL in loops. Never do this. - Cache pretty much everything that you get back from the database if you can, using a static variable. (Not a global; a static variable local to a function or method, or a private class variable.) If you're loading complex objects, cache the fully prepared version. That not only provides a performance boost, but also provides you with a good single-point-of-optimization because it's then much easier to shift that from a static variable or static array to a memcached storage. - Limit your individual transfers. Oft-forgotten, but remember that every file the browser has to request is another HTTP hit on the server. Even if the response from the server is nope, no change, it's still an HTTP hit. That can really hurt your effective performance, both on the server side and client side. Merge your CSS and JS into as few files as reasonable, even if that means that you send more than you need to on the first page request. It helps overall. You can do that manually or automatically. (Drupal, for instance, auto-aggregates CSS and in the next version will auto-aggregate JS, too. That's been a big performance boost.) The same goes for image files. - Apropos of the last, Firebug! The latest version has a great profiler that can show you how long each HTTP request takes. You may find that you spend most of your browser-load time on things that don't involve PHP at all. - EXPLAIN your SQL. That is, the MySQL EXPLAIN command prefixed to any SELECT query will tell you how MySQL is going to parse and process it. Odds are good that adding a few well-placed keys/indexes will make your SQL an order of magnitude faster or more. Also, watch out for filesort. Any time a query has to do a filesort, it gets slow. It always has to filesort if you are doing a WHERE and ORDER BY that use fields in different tables. Avoid that if you can. Much more information in a MySQL group. :-) Again, benchmark it from every direction you can. Odds are, though, that your PHP code itself is not the bottleneck but the server configuration, SQL server, HTTP traffic, etc. are where you're really dying.

[PHP] Re: filter input; escape output; Email Text
Hello, on 07/20/2007 06:03 PM Richard Lynch said the following: So, I'm trying to be more consistent about escaping my output. I do something like this (only prettier): if (!isset($_REQUEST['blah_id'])) error_out(Bad blah_id input); $blah_id = (int) $_REQUEST['blah_id']; $blah_id_sql = mysql_real_escape_string($blah_id, $connection); $query = select title from blah where blah_id = $blah_id_sql; $blah = mysql_query($query, $connection) or die(DB Error); list($title) = mysql_fetch_row($blah); $title_html = htmlentities($title); $title_email = SOME_FUNCTION_HERE($title); What function should be used to escape output to make it 100% kosher for an email Subject and/or Body, in a plain-text email? The original title came from the outside world, had mysql_real_escape_string() applied to it, and was crammed into the DB. It could have ANY kind of malicious text in it. We do NOT send (and will NEVER send) HTML enhanced (cough, cough) emails. For simplicity sake, I'd probably be happy with a more restrictive function that covered both Subject and Body in this instance. Message headers should be encoded with q-encoding, which is a variant of quoted-printable that includes character set information. This is a bit complicated (too many RFCs to read) but you can use this MIME message composing class to encode your message headers properly. This class also escapes properly line breaks in headers. Malicious line breaks are used by spammers to attack form mail like scripts. They inject line breaks to insert new headers to the message that can make the messages be sent to other addresses. http://www.phpclasses.org/mimemessage -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Bundled GD compiling?
I'm confused as to certain issues regarding the bundled version. The documentation says:: To use the recommended bundled version of the GD library (which was first bundled in PHP 4.3.0), use the configure option --with-gd. GD library requires libpng and libjpeg to compile. Note: When compiling PHP with libpng, you must use the same version that was linked with the GD library. This (to me) seems ambiguous. How am I suppose to know which libpng the bundled GD library used? So how should I configure? http://www.libgd.org/FAQ_PHP ./configure --with-gd -with-png-dir=/usr --with-jpeg-dir=/usr --with-freetype-dir=/usr' The FAQ says this is all the features?

Re: [PHP] session_decode from session handler
I have a similar problem I am facing with session data stored in the database
from the set_session_handler.
What I am trying to do is show a list of online users and the page they are
currenlty viewing. For this purpose I am query the sessions table to get the
list of session and from that I loop through to get the session data of each
online user. But for some reason, I cannot decode/un-serialise the session
data. Any pointers ?
cheers,
Jeffery

How did you get $data?
If it's just serialized data, you can simply call unserialize instead
of session_decode.

just following up on this problem. I am using PHP 5.2.3. I also do remember
that previously in older versions of PHP, I used to see the session data was
the actual serialised data. But now with my testing it just seems to be one
long string. Which leads me to beleive that there is some kind of encoding
taking place.
