[PHP] PHP5 OOP: Abstract classes, multiple inheritance and constructors
Example/working code here: https://gist.github.com/mhulse/5833826 Couple questions: 1. Is there anything wrong with the way I'm using the abstract class? If so, how could I improve the logic/setup? 2. Is there a way for me to pass $foo to the parent class, from the child, without having to ferry that variable through the abstract class? In other words, is there such a thing as: parent::parent::__construct($foo); ... I want to have my abstract class constructor do things, yet I'd like to avoid having to repeat myself for when it comes to passing constructor arguments from the child. Any tips would be appreciated. Sorry if silly questions. Thanks! Micky -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] php5-fpm segfault
You think this is PHP's bug? I'm not sure. Because PHP installed not latest version and yesterday i tune memory_limit setting to 256M (was -1) and no segfaults registered since that moment. I think, bad designed script allocate too much memory and php-fpm worker become mad and kill himself. But it's hard to find the culprit in a huge number of scripts. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP5 cgi Suexec htaccess rewrite issue
I am running a server with cPanel on and want to have php run as a cgi with Suexec enabled I cannot seem to rectify an issue, when I set the handler to cgi, my rewrite rules on one of my sites stop working Sample url: http://examplesite.com/ad/123-abcde/ The rewrite rule for this is below; RewriteEngine on RewriteBase / RewriteRule ^ad/([0-9]+)(.*)$ ./index.php/ads/ads/action/viewAd/frmAdsID/$1/adTitle/$2 [L] Currently the php 5 handler is dso, and the rewrite rule works perfectly. If the handler is set to cgi, the rewrite rule does not work and I the site just displays the home page. I am at a loss and would appreciate some help. Thanks in advance!

Did you make the changes accordingly in php.ini? I recall that cgi/fastcgi requires different configuration than from isapi type - dll/dso. I don't know how httpd handles impersonation on *nix platform as I've never had to configure it that way. Here's a few from the php.ini ; The root of the PHP pages, used only if nonempty. ; if PHP was not compiled with FORCE_REDIRECT, you SHOULD set doc_root ; if you are running php as a CGI under any web server (other than IIS) ; see documentation for security issues. The alternate is to use the ; cgi.force_redirect configuration below ; http://php.net/doc-root ; cgi.force_redirect is necessary to provide security running PHP as a CGI under ; most web servers. Left undefined, PHP turns this on by default. You can ; turn it off here AT YOUR OWN RISK ; **You CAN safely turn this off for IIS, in fact, you MUST.** ; http://php.net/cgi.force-redirect ; if cgi.nph is enabled it will force cgi to always sent Status: 200 with ; every request. PHP's default behavior is to disable this feature. ; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI. PHP's ; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok ; what PATH_INFO is. For more information on PATH_INFO, see the cgi specs. Setting ; this to 1 will cause PHP CGI to fix its paths to conform to the spec. A setting ; of zero causes PHP to behave as before. Default is 1. You should fix your scripts ; to use SCRIPT_FILENAME rather than PATH_TRANSLATED. ; http://php.net/cgi.fix-pathinfo ; FastCGI under IIS (on WINNT based OS) supports the ability to impersonate ; security tokens of the calling client. This allows IIS to define the ; security context that the request runs under. mod_fastcgi under Apache ; does not currently support this feature (03/17/2002) ; Set to 1 if running under IIS. Default is zero. ; http://php.net/fastcgi.impersonate Note that the above is from old config file and is configured for PHP to run as FastCGI on IIS7.5. There maybe recent changes regarding httpd and impersonation. Go through the php.ini and make all relevant changes regarding 'cgi'. Regards, Tommy

[PHP] PHP5+APACHE 2.2 + Windows 2003 production server
Hi all PHP manual state We do not recommend using a threaded MPM in production with Apache 2. Use the prefork MPM instead, or use Apache 1. For information on why, read the related FAQ entry on using Apache2 with a threaded MPM ( http://www.php.net/manual/en/install.windows.apache2.php ) From apache.org the compiled exe you can download it seems compiled against threaded MPM. Even the all-in-one packages like WAMPSERVER (http://www.wampserver.com/en/) or XAMPP Light install PHP as Apache module on threaded MPM Apache So I'm wondering, is the manual outdated, or should I consider other configuration to install on my production servers?

[PHP] php5-mhash disabled...
I just saw that mhash is disabled in the spec file for php5 if SUSE version is 11.0 or higher. Simple question, does it do any harm? I know it's been deprecated in favor for hash, but I have quite a few apps using mhash still, so if it doesn't do any harm I thought I'd continue using it until all apps has been remade for hash. I really didn't find any relevant info on it with a quick Google search, so I ask you fellows.

[PHP] PHP5 - SOAP extension and WSDL generation
Hi there, I'm trying to find out how to generate a WSDL with the functions I am providing as web services, and I'm finding various posts on the net that say it's not possible with the SOAP extension built in PHP5. At the same time, I find that http://www.php.net/manual/en/soap.constants.php lists four constants that have to do with WSDL caching: WSDL_CACHE_NONE (integer) WSDL_CACHE_DISK (integer) WSDL_CACHE_MEMORY (integer) WSDL_CACHE_BOTH (integer) which apparently are only used in the http://www.php.net/manual/en/soapserver.soapserver.php method. so I'm a bit confused about the lack of info there. Why would the extension not include a WSDL-generation method for one given server object while other libraries (NuSOAP and PEAR::SOAP) do? Isn't that kind of pushing users away from the core extension? I mean, generating a WSDL is not a funny job, but many services will need one and a developer doesn't want to be updating his at every change he makes in his service function, does he?

[PHP] PHP5 DOM Problem
Hi there. I don't kno id this is the correct place to post but...
I am using the PHP5 DOM to make up RSS Feeds ..
A Problem I have is I want to make this up for itunes..
?xml version=1.0 encoding=UTF-8?
rss version=2.00 xmlns:itunes=http://www.itunes.com/dtds/podcast-1.0.dtd;
etc..
I use..
$p_dom = new DOMDocument('1.0','UTF-8');
$p_rss = $p_dom-createElement('rss');
$p_rss-setAttribute('version', '2.00');
$p_rss-setAttribute('xmlns:itunes','http://www.itunes.com/dtds/podcast-1.0.dtd');
$p_dom-appendChild($p_rss);
which is working for me.. Debian (PHP 5.2.6-2+b1)
but doesn't work on some other people with other versions of php5 ( I don't
know yet which version they have)
they only get
?xml version=1.0 encoding=UTF-8?
rss version=2.00
So the name space is missing..
So I looked up http://nz2.php.net/manual/en/domelement.setattribute.php
and it says the correct way is to use createElementNS.. but I have tried and
tried and I cannot get it to make up what I want it to do.
can someone help?
I also want to make something like
?xml version=1.0 encoding=UTF-8?
rss version=0.91 xmlns:media=http://search.yahoo.com/mrss/;
xmlns:dcterms=http://purl.org/dc/terms/;
xmlns:gm=http://www.google.com/schemas/gm/1.1;
xmlns:av=http://www.searchvideo.com/schemas/av/1.0;
xmlns:dc=http://purl.org/dc/elements/1.1/;
for mediarss feeds + other types . but I can't seem to be able to use
CreateElementNS to make this up either
Can someone help??

http://www.javaworld.com/javaworld/jw-09-2003/jw-0905-toolbox.html :
A fundamental precept of OO systems is that an object should not expose any
of its implementation details. This way, you can change the implementation
without changing the code that uses the object. It follows then that in OO
systems you should avoid getter and setter functions since they mostly
provide access to implementation details.
To see why, consider that there might be 1,000 calls to a getX() method in
your program, and each call assumes that the return value is of a particular
type. You might store getX()'s return value in a local variable, for example,
and that variable type must match the return-value type. If you need to
change the way the object is implemented in such a way that the type of X
changes, you're in deep trouble.

No,but in the first one, you can control, from within the class/method, what
data is actually allowed to be injected into that variable. Whereas the second
example would allow you to stuff any type of data into that class variable.
That might not be a good thing.

it is different, by your very definition. quote 'Data Hiding IS
Encapsulation' so the difference in the 2 examples you supplied is that the
first one is an example of encapsulation, whereas the later is not.
encapsulation provides control. it reduces the possibility of client code
binding to implementation details which decreases coupling. go into the
archives, you will find the argument from last year. its in the same one
about interfaces, that we pretty much re-hashed this week.

What he means is don't ask for the data literally (by property name) ask
for it via a method. This allows wrapping the data in work. This is a
moot issue in PHP since PHP allows trapping the property accessor.

one w/ no methods :O

strangely enough, last year when we argued, it became clear the definition
of encapsulation varies quite a bit across the people who subscribe to this
list, tho i posted 4 examples from texts ive read over the years that all
essentialY incorporate data hiding into the definition of encapsulation.
All I can say is that all my __set methods do data sanitizing and
validation, which is were I think it should be done. If anybody thinks this
might be a bad thing, please by all means explain why it is bad.
right; 100%. and even if setters are as simple as
function setStuff($stuff) { $this-stuff = $stuff; }
the client is still being driven through a well defined public interface,
which supports the ability to add validation logic later on w/o impacting
client code. you could also change the internal variable from $stuff to
$goofy and it would be transparent to the client. the point here is
indirection, which in programming terms is basically synonymous w/
flexibility. yes there are costs, runtime performance, system complexity,
but these are the tradeoffs for flexibility. when you take it to a higher
level thats what design patterns are all about. standardized techniques to
incorporate flexibility into an application.

i dont think its moot. if your trapping it via __get() or __set() its still
the same action; driving the client through a well defined interface; if it
just happens to have the same name as the property itself, its still the
same concept. you have the 'work' in the magic methods (at a minimum the
initial part), instead of the getters and setters you would build yourself.
and personally, i think it much cleaner to have separate methods for each of
the properties rather than one big function which has to internally route
control via some sort of logic, be it conditional, variable functions or
w/e.
besides which, for the magic methods to work, the variables have to be
'inaccessible' according to the docs which means protected, private, or
non-existent; and barring the case of non-existent we are right back in the
realm of encapsulation.
unless you meant something different by 'trapping the property accessor';
which you usually do pull some unexpected stuff so im waiting for your next
clever example to prove me wrong :D

return $this-{'get'.ucFirst( $name )}();

[PHP] PHP5 and the DOM model
Hello! Seems that PHP gets more and more object oriented, which is good. I am now running a course in PHP, using PHP 5, where we are going to use the *DOM* interface. I am trying to teach them good OO practices, meaning that we insistently hide properties and expose them as get or set methods. Looking at the PHPs *DOM* implementation, I see that many of the properties are exposed directly, without even offering get methods. 1. Is there something I am misunderstanding orotherwise missing? (I havenot used *DOM* in PHP before). 2.This poses a pedagogical problem for me as a teacher. How do I explain this contradiction to my students?

[PHP] PHP5 strtotime
I use PayPal as my ecommerce solution and I have a PHP script that captures variables posted from PayPal to populate my database.

Samuel Marshall PHP's error value for dates translates to 6 PM 31 December 1969 when formatted, that is, right before the Epoc. That happens when you feed strtotime a string it can't parse, for instance. Looking at the string you list, the year is listed twice. I very much doubt strtotime can grok that.

[PHP] PHP5 and XSLTProcessor: disable validation
Hi, i'm currently learning php by implementing a blog system. This uses xsl for transformation to (x)html. It is working so far, but it is slow. As far as i can see the XSLTProcessor is doing a validation. Doing the same transformation with xsltproc (the command line tool for libxslt) takes about the same time. Adding the parameter --novalid to xsltproc speeds up things dramatically. Is there any possibility/option/parameter/whatever to stop XSLTProcessor validation? I've found nothing in the documentation.

Re: [PHP] PHP5 Speed Issues
Hi everyone! Generaly author of the first e-mail is right. Ofcource, crawling over the code and getting out of it a few milliseconds off doesn't make it worth, but you can learn what is good and what is bad and write your code correctly from the start. Why not to use foreach ($data as $value) if it's better - faster and takes less memory. That's just a habbit on code style. I can bet, that nobody knows or remembers that echo has alternative syntax, with works faster and is easier to write if you cave to echo a complex string with many variables and static text, for example The ordinary: echo 'Hi! My name is '.$_GET['name'].'. I'm '.$_GET['age'].' and I live in '.$_GET['country'].'.'; The alternative: echo 'Hi! My name is', $_GET['name'], '. I'm ', $_GET['age'], ' and I live in ', $_GET['country'], '.'; I have an aplication with doesn't eat all CPU, just about 50-60%, but it eats all 3GB of ram. And not because it is poorly written. It serves ~160 000 - 170 000 requests/hour, that's ~3 960 000 hits a day + another 600 000 hits to the application's WEB part. Just one server could handle, but it can't because of WEB server's FastCGI implementation (they have a patch for that soon released). Just ONE Intel E6600 server with Lighttpd and PHP can handle such load if the code is optimised and written correctly.

Well obviously you can always write horrible code but if you write code
that is easy to maintain it's usually not that kind of code.

Well obviously you can always write horrible code but if you write code

thats pretty subjective; ive worked w/ plenty of 'easy to maintain' code
that could
only have hardware thrown at it by a load balancer. which i consider a real
mess.
even then the design of the load balancer will have to maintain request
forwarding
to particular hosts unless the code already supports or is given support for
session
storage in a common location all the webservers can address.
i personally am not a fan of the 'just throw hardware at it' adage, if it
can be called that.
i was recently at the d.c. php conference and heard a talk from a gentleman
on behalf
of yahoo. he says they are *very* picky about getting new hardware; yahoo
wants clear
rationale for the addition of any new hardware into the system. in short;
they advocate
writing solid code because it saves them money in the long run.
what i see happening when people throw hardware at their problem is that in
early stages
it works great. then further down the road the software is unable to be
easily spread to
multiple systems and then guess what; you end up spending man hours to do
something that
could have been done in the first place. another issue is randomly added
machines can be
hard to maintain because their roles are not clearly defined.
what im saying is adding hardware to a system is natural and relevant, but
ensure it is a
good decision by evaluating alternatives before arbitrarily 'throwing
hardware at the problem'.

Hi Robert, Stut List Thanks for your replies which arrived after I had gone to bed |-Z Robert :- In PHP5 objects are no longer copied when assigned.

Start here: http://php.net/language.oop5.cloning It's amazing what a good night's sleep will do :-) I could not find that page last night even though I was sure it must have existed and I can see that it is a well documented and encountered problem.

I have hundreds of $Working_Class = $Under_Class; lines in my code as well as $Upper_Class = $Aristocracy; lines too. I think the documentation on references needs updating to reflect PHP 5's behaviour a little more accurately because I can see this causing serious problems to somebody just copying their code blindly. I have just built a client a development server using php5 instead of php4 and turned zend.ze1_compatibility_mode on so that their old CMS would work - I just hadn't realised that the cloning problem was solved by this.

[PHP] php5 - possible bug discovered
Hi,
I think I have discovered a bug in php5. If I haven't, I've discovered
a bug in the documentation or a bug in my brain.
php -v :-

Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
I've attached a code snippet for those that want to save it and try
running it and it's also pasted here :-
?php
class Class_1
{
private $Text;
function __construct($Text)
{
$this-Text = $Text;
}
function Set($Text)
{
$this-Text = $Text;
}
function Display()
{
print $this-Text . \n;
}
} // End Class_1
class Class_2
{
private $Text;
private $C1;
function __construct($Text)
{
$this-Text = $Text;
$this-C1 = new Class_1('From David');
}
function Set_C1($Text)
{
$this-C1-Set($Text);
}
function Display()
{
print $this-Text . \n;
$this-C1-Display();
}
} // End Class_2
print Below is T1\n;
$T1 = new Class_1('Hello');
$T1-Display();
print Below is T2\n;
$T2 = new Class_2('World');
$T2-Display();
print Copying T2\n;
$T3 = $T2;
print T2 Copied, original value is :-\n;
$T2-Display();
print Copy of T2 (T3) value is :- \n;
$T3-Display();
print Changing T3\n;
$T3-Set_C1(This clears Dave);
print T3 Change complete, new value is :-\n;
$T3-Display();
print Below is T2 which shouldn't have changed !!! \n;
$T2-Display();
// var_dump($T1);
?
The output it produces is :-
% php -e bug.php
Below is T1
Hello
Below is T2

T2 Copied, original value is :-

Copy of T2 (T3) value is :-

Changing T3
T3 Change complete, new value is :-

Below is T2 which shouldn't have changed !!!

%
Now I would expect that $T2 would not change when I changed $T3.
Reading the documentation :-
http://www.php.net/manual/en/language.references.whatdo.php
... Note: Not using the operator causes a copy of the object to be
made. If you use $this in the class it will operate on the current
instance of the class. The assignment without will copy the instance
(i.e. the object) and $this will operate on the copy, which is not
always what is desired. Usually you want to have a single instance to
work with, due to performance and memory consumption issues.
This effectively states that $T3 is a 'COPY' of $T2 and $T3 works on the
copy, not the master yet in the above snippet, the copy and the master
have both been changed. Further documentation mentions that the copy
starts off as a reference and only becomes a copy when it is changed.
This doesn't seem to be happening.
I found this because in my actual application I was using :-
Master.class
...
$Clone = $this;
$Clone-Do_Something;
and later in master.class I did :-
$this-Do_Something_Else
and php barfed with :-
PHP Fatal error: Call to a member function Function_Name() on a non-object
I had deleted the missing object in $Clone but not in the master (this
was the whole idea of working on $Clone - I didn't want to delete the
object in the master !!).
I can't find anything similar in the bug database on php.net (but I may
be looking in the wrong place) and I can't believe that I'm the first
person to encounter this.
Can anybody explain if this is a bug or if I have misunderstood the
documentation ?

The turkish translation files of such opensource software usually use gettext and .po files for i18n and are always a bit behind the translation status of other european languages. I decided to work a bit on some of those tr.po files on my local linux box (opensuse 10.2 with apache 2.x mysql 5.x and php 5.2.0). But when I started the test phase in turkish I couldn't test because of strange errors. I contacted the forum of gallery2 and after investigating the problem I stumbled over an answer of bug #35050 at bugs.php.net: http://bugs.php.net/bug.php?id=35050 and its status: WONT FIX Now that's really great. It means that turkish hosting providers cannot use php5 at all! And as of the news on php.net php4 will not be supported or developed any further after the end of 2007! Will Turks really have now to wait for a php6? When will that come out? That's seems to me to be a sort of discrimination of turkish language in php5. Is it technical so difficult to develop a patch for this bug? Sincerely -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] PHP5 objects access/instantiation model
Hi, new to PHP5 and I have a question about the object model.
I want to be able to create a class which is allows abstraction from
specifics. So for one example, imagine a generic database connection wrapper
which can have multiple drivers depending on the database used. Some of the
functionality is generic, some is database specific (mysql_ , odbc_). So:
Class MySQL_driver {
public prop1 ;
public connect() {
echo Foo;
}
public runquery() {
echo Foo;
}
...
}
Class ODBC_driver {
public prop1 ;
public connect() {
echo Foo;
}
public runquery() {
echo Foo;
}
...
}
Class generic {
public $driver = null ;
function __construct($connection_type) {
if $this-connection_type = MySQL {
$this-driver = new MySQL_Driver ;
} else {
$this-driver = new ODBC_Driver ;
}
}
function authenticate { // Using the
non-generic connect() from the selected driver
$this-driver-prop1 = fooey // These references
work fine from within the generic class
echo $this-driver-prop1 ;
echo $this-driver-function1 ;
}
function errors { //
Reporting non-generic errors from the selected driver
}
function debug {
}
...
}
$gen = new generic(MySQL) ; //
Instantiate the generic database object, which determines its own driver
$gen-driver-prop1 = fooey // but they
fail from here
echo $gen-driver-prop1 ;
echo $gen-driver-function1 ;
$gen-authenticate() ; // this
works ok though, so everything is created correctly
So I want to access generic functions as $generic-authenticate(), and
database specific functions $generic-driver-runquery. This allows the top
level code to be able to be completely generic and not know anything about
the underlying database.
But I can't ! I can't find a way of accessing the encapsulated object
(driver) from the instantiator of generic. Is it possible ?
I guess there are lots of workaround ways. I could write lots of
middleman code in generic and use things like __set and __get etc but its
lots of extra overhead. I also know I could use extends but that makes the
code the wrong way around (MySQL_Driver would have to extend generic), hence
the top-level application would have to include code to determine which
driver to create rather than the db object determining its own connection
driver to use. This is true also for just lumping everything in a single
class per db type.
Surely it must be possible ? Or am I missing something ?
I also don't really get the idea of interface and abstract classes ? They
don't seem to be any practical use ? Maybe that's me ? Anyway, not really
relevant to this post ...
Please, please can someone help !!

You want a factory class that creates an instance of the appropriate
driver object. The driver object SHOULD extend the generic class.
?php
class DbFactory
{
function __construct()
{
// :)
}
function getConnection( $type, $params )
{
if( $type == 'MySQL' )
{
return new DB_Driver_MySQL;
}
else
if( $type == 'ODBC' )
{
return new DB_Driver_ODBC;
}
return false;
}
}
class DB_Driver_Generic
{
public $var1;
public $var2;
function __construct()
{
}
function runQuery( $query )
{
}
}
class DB_Driver_MySQL extends DB_Driver_Generic
{
function __construct()
{
parent::__construct();
}
}
class DB_Driver_ODBC extends DB_Driver_Generic
{
function __construct()
{
parent::__construct();
}
}
?
Cheers,
Rob.

there is a lot of usefulness in these constructs; look into design patterns.
also, there are code libraries already written w/ the abstraction you are
trying to develop.
im not discouraging you from developing your own, but it may be helpful for
you to study some of the other code.

Re: [PHP] PHP5 objects access/instantiation model (correction)
some ideas about class design:
1. properties should normally (read almost always) be private.
2. the apps interface to the DB [connection] is via the 'generic'
class, the app should have to know nothing about the drive object and
should have no direct access to it.
3. use an interface definition for your drivers (so they all share a
common set of method ... a common interface ;-))
this leaves you with the problem of wanting to write as little boilerplate
code for making the functionality each driver class implements available via
the 'generic' class.
I would suggest either a few simple functions like so:
class DB {
function query() {
$args = func_get_args();
return call_user_func_array(array($this-driver, __FUNCTION__),
$args);
}
}
which you can simplify into something like:
class DB {
function __call($meth, $args) {
$func = array($this-driver, $meth)
if (!is_callable($func))
throw new Exception('undefined interface:
'.__CLASS__.'::'$meth);
return call_user_func_array($func, $args);
}
}
just an idea :-) ... this seems to me to be something along the decorator
pattern,
you could choose to do something along the lines of the factory pattern, where
by
your factory returns a 'driver' object which your application uses (not caring
what
class of driver it is) ... this would also require that your driver classes
share a
common interface (actually using a interface definition to enforce it is a
seperate issue).
an interface example:
interface DBDriver {
function query($sql, $args);
function commit($id);
function rollback($id);
}
class MySQL_DBDriver implements DBDriver {
function query($sql, $args) { return mysql_query($sql, $args); }
function commit($id); { return true; }
function rollback($id); { return true; }
}

// but they fail from here
echo $gen-driver-prop1 ;
echo $gen-driver-function1 ;
what fails exactly? what is the error?
// this works ok though, so everything is created
// correctly
$gen-authenticate() ;
PS. I would hazard a guess and say the generic class is not very generic -
it's quite specifically a 'database' class, it is an 'abstract' class (not in
the
php syntax sense) in that the DBMS specifics are hidden away in helper/plugin
classes.

Re: [PHP] PHP5 objects access/instantiation model (correction)
Robert,
I looked at your code in InterJinn a couple of times; i havent gone over all
of it mind you but it looks pretty sweet.
have you had a look at any of the other frameworks i mentioned earlier in
this thread?
ez components, onPHP, and now there is a new one ive found (in recent
thread) Radicore. i really like the xsl approach
for templates.
All,
also, more on topic; there are many different ways to use interfaces and
abstract classes in many different design patterns.
they all have purpose, pros and cons. take for instance factory method and
abstract factory; where the former uses inheritance
the later uses composition. the former can produce only a single class of
products, but the abstract base class rarely needs revision;
whereas the later can produce sets of related product classes; yet every
time a new product class is needed or deprecated the
abstract factory [interface] needs revision.
Steve,
you might also check out
http://www.phppatterns.com/docs/start
i dont think its been maintained in a while, but its a great place to start.
also, i think PDO is pretty sweet, but really its only the base of a strong
db abstraction layer, such as what youll find in ez components.
-nathan
ps.
i cant decide if i should build my own db layer around pdo or go for a
pre-built one from an aforementioned framework; only time will tell :

throw new Exception('undefined interface:
'.__CLASS__.'::'$meth);
return call_user_func_array($func, $args);
}
}
just an idea :-) ... this seems to me to be something along the decorator
pattern,
you could choose to do something along the lines of the factory pattern,
where by
your factory returns a 'driver' object which your application uses (not
caring what
class of driver it is) ... this would also require that your driver
classes share a
common interface (actually using a interface definition to enforce it is a
seperate issue).
an interface example:
interface DBDriver {
function query($sql, $args);
function commit($id);
function rollback($id);
}
class MySQL_DBDriver implements DBDriver {
function query($sql, $args) { return mysql_query($sql, $args);
}
function commit($id); { return true; }
function rollback($id); { return true; }
}

PS. I would hazard a guess and say the generic class is not very generic -
it's quite specifically a 'database' class, it is an 'abstract' class (not
in the
php syntax sense) in that the DBMS specifics are hidden away in
helper/plugin classes.

It's very different in many respects from other styles of coding. It's an MVC approach for the most part but the way libraries are accessed is different than what I've seen elsewhere. In general class names are only used in two places... when extending a class, and in the registration of a class to a service. Instead classes are registered as services/libraries and instances are retrieved by a general factory mechanism that returns the instance based on the service/library name. In this way almost all aspects of the framework can be overloaded, even if they are core features, without ever touching the core code itself or ever having to change class references within your code since you can just register a different class for the service and all existing uses of that service will now use the newly registered version. This was very useful even before PHP5 got autoload (and even still IMHO) because the loader would load the class's code on an as requested basis. have you had a look at any of the other frameworks i mentioned earlier in this thread? ez components I work with a version of ez components on almost a daily basis (pre-existing CMS that a client had set up) ... it makes me scream because their template engine is godawful because it uses a block approach that requires changing the PHP code if you move blocks out of registered nestings. It's absolutely horrible. The code for the classes is generally disgusting also, but that's just my opinion. Fortunately, I was allowed to hook in InterJinn as needed and so new stuff uses the ez components framework bu generally punts the work to InterJinn modules / services / and templates. We've found run time speed to be much greater for those modules and the maintainability of the content is much, much, easier. , onPHP, and now there is a new one ive found (in recent thread) Radicore. i really like the xsl approach for templates. XSL is nice, but it's complex for the average Joe content developer. When I created InterJinn I wanted something with similar capabilities but without the restriction of well-formed-ness for the HTML content in general (so that existing content could still be adapted with minimal disruption - my new site is XHTML strict). So I created custom tags that can wrap well-formed or not-so-well formed content and process as necessary. Generally speaking though the template engine isn't in any way limited to just custom tags, it can include anything since it's pluggable and extendable. Also, unlike most other template engines, TemplateJinn compiles to the actual PHP code the web server loads, so there's no run-time hit, and in fact, there can be a run time bonus on some aspects. For instance headers, footers, etc, etc can be punted to separate templates but at compile time they are brought together to create the final page. That's not to say TemplateJinn can't be used at run-time, it can be, and it is in the case of the ez components hooking since ezcomponents uses a front end loader. Cheers, Rob. -- ...

Re: [PHP] PHP5 objects access/instantiation model (correction)
You probably ought to have:
class mysql_driver extends generic_driver {
}
Seems like that would be the most reasonable OOP model, imho.
That said, I suspect that if you do something like:
$driver = $this-driver;
You then may be able to access the driver-specific data using
$driver-propl; etc.

Hi, new to PHP5 (and the forums evidently !) and I have a question

object model.
I want to be able to create a class which is allows abstraction from
specifics. So for one example, imagine a generic database connection
wrapper
which can have multiple drivers depending on the database used. Some
of the
functionality is generic, some is database specific (mysql_ , odbc_).
So:
Class MySQL_driver {
public prop1 ;
public connect() {
echo Foo;
}
public runquery() {
echo Foo;
}
...
}
Class ODBC_driver {
public prop1 ;
public connect() {
echo Foo;
}
public runquery() {
echo Foo;
}
...
}
Class generic {
public $driver = null ;
function __construct($connection_type) {
if $this-connection_type = MySQL {
$this-driver = new MySQL_Driver ;
} else {
$this-driver = new ODBC_Driver ;
}
}
// Using the non-generic connect() from the selected driver
function authenticate {
$this-driver-prop1 = fooey
// These references work fine from within
// the generic class
echo $this-driver-prop1 ;
echo $this-driver-function1 ;
}
// Report non-generic errors from the selected driver
function errors {
}
function debug {
}
...
}
$gen = new generic(MySQL) ;
// Instantiate the generic database object, which
// determines its own driver
$gen-driver-prop1 = fooey
// but they fail from here
echo $gen-driver-prop1 ;
echo $gen-driver-function1 ;
// this works ok though, so everything is created
// correctly
$gen-authenticate() ;
So I want to access generic functions as $generic-authenticate(), and
database specific functions $generic-driver-runquery. This allows
the top
level code to be able to be completely generic and not know anything
about
the underlying database.
But I can't ! I can't find a way of accessing the encapsulated object
(driver) from the instantiator of generic. Is it possible ?
I guess there are lots of workaround ways. I could write lots of
middleman code in generic and use things like __set and __get etc
but its
lots of extra overhead. I also know I could use extends but that makes
the
code the wrong way around (MySQL_Driver would have to extend generic),
hence
the top-level application would have to include code to determine
which
driver to create rather than the db object determining its own
connection
driver to use. This is true also for just lumping everything in a
single
class per db type.
Surely it must be possible ? Or am I missing something ?
I also don't really get the idea of interface and abstract classes ?
They
don't seem to be any practical use ? Maybe that's me ? Anyway, not

Yeah. I've been working on re-writing it using bits from everyone !! It's a

recommend it, it's the only way to learn. Some things just can't be learnt
from the manual!

Re: [PHP] PHP5 or PHP4 this is the question
You should get a new server that supports PHP 5.2.1. PHP 4 is dead. It hasn't had a non-security/bug release in years. PHP 5 is 3 years old. The one and only reason to care about PHP 4 at this point is if you're writing something that has to run on any possible cheap shared web host, and even many of those are starting to move to PHP 5.2. If you're on a shared host, get a new shared host that supports PHP 5.2. If you're running your own server, install PHP 5.2. If your server's sysadmin won't let you upgrade to 5.2 or won't give yo a new box on which to put 5.2, then get a new sysadmin because he is going to suffocate your development. As to the liklihood of portability, it depends on what you've actually done. Anything interesting with OO starts in PHP 5, but you said you're not using that. Are you passing objects (even stdClass objects)? That changes. Are you using any of the newer array handling functions, like array_combine? PHP 5 added a lot of them, many of which can be implemented in user-space using PEAR::PHP_Compat. There are more subtle differences, too. So it's quite possible that if you're not doing anything exotic you can downgrade your script without too much trouble. You're still better off doing the Internet a favor and removing one more PHP 4 server from existence. It will make your life easier in the long run.

Hi list,
I have a class which I use to parse simple bbcode inside some comments.
I noticed on PHP5 that scope of preg_replace function is changed
when function is called inside a class. To the point:
[CODE]
class PHS_editor
{
...
function parse_content( $str = null )
{
$from_arr = array( @\[B\](.*?)\[\/[EMAIL PROTECTED],
@\[U\](.*?)\[\/[EMAIL PROTECTED], @\[I\](.*?)\[\/[EMAIL PROTECTED],
@\[URL=([^\]]*)\]([^\[]*?)\[\/[EMAIL PROTECTED],
@\[IMG=([^\]]*)[EMAIL PROTECTED],
@\[QUOTE=([^\]]*)\]([^\[]*?)\[\/[EMAIL PROTECTED]
);
$to_arr = array( 'b\1/b', 'u\1/u', 'i\1/i',
'a href=\1 target=_blank\2/a',
'img src=\'.stripslashes(
\*$this-get_image_location*( '\\1' ) ).'\ border=\0\',
'table width=\98%\ align=\center\
cellpadding=\1\ cellspacing=\0\ border=\0\ class=\form_type\.
tr.
td class=\maintext\'.stripslashes(
\*$this-remove_mytags*( '\\2' ) ).'/td.
/tr.
/table'
);
if( is_null( $str ) )
$str = $this-editor_content;
return preg_replace( $from_arr, $to_arr, str_replace( ,
nbsp;, nl2br( $str ) ) );
}
...
}
[/CODE]
When it gets to parse [IMG] tags I get Fatal error: Using $this
when not in object context in So it seems they changed the scope
for preg_replace callback functions. As this function is called inside
the method shouldn't it have the scope of the class?
Is there a workaround for this? I cannot declare a function
get_image_location which will staticly call the method bcuz I use
variables from instanced class.
How are you trying to use this class? It sounds like you're trying to
use the method statically. When a method is called statically it does
not have a $this.

Yes, method was called staticly. Strange tho in php 4 it worked.
Thnx for enlighting me with this.

[PHP] php5 cert
are volcan exams really harder than actual php5 exam as phparch asserted?
Re: [PHP] php5 cert
Actually I found the real exam harder than the test exam. It may have just been the question set I ended up with, but it was a lot more nitpicky on details that I rarely use in my work.

[PHP] PHP5 Static functions called through __call() that don't exist... yet
Hi all,
I am building an assertType object using static functions. What I want to
keep away from is the following:
code
public static function assertString($para){
return $answer;
};
public static function assertBool($para){
return $answer;
};
...
public static function assertArray($para){
return $answer;
};
/code
What I would like to do is replace this with the following:
code
if (!class_exists('TypeAssert')) {
class TypeAssert {
private static $types = array(
'array','bool','float','integer','null','numeric',
'object','resource','scalar','string'
);
public static function __call($method,$arguments) {
$obj = self::assertStandardTypes($arguments[0]);
return $obj-$method;
}
public static function assertStandardTypes($para) {
$r = TypeAssert::getTypesObject();
if (is_array($para))$r-array = true;
if (is_bool($para)) $r-bool = true;
if (is_float($para))$r-float = true;
if (is_integer($para)) $r-integer = true;
if (is_null($para)) $r-null = true;
if (is_numeric($para)) $r-numeric = true;
if (is_object($para)) $r-object = true;
if (is_resource($para)) $r-resource = true;
if (is_scalar($para)) $r-scalar = true;
if (is_string($para)) $r-string = true;
return $r;
}
public static function getTypesObject() {
$obj = (object) '';
for ($i = 0; $i count(self::$types); $i++) {
$obj-{self::$types[$i]} = (bool) false;
}
return $obj;
}
}
}
echo('pre');
echo(TypeAssert::string('test'));
echo('/pre');
/code
I don't think this is possible (see
http://marc.info/?l=php-generalm=114558851102060w=2
). But I would LIKE for it to work (currently, the above code doesn't).
Anybody have any insight on how I might get this to work?
Thanks!

[PHP] php5 include() problem
I've got a cgi file in my cgi-bin folder that I'm calling with include(). It worked with php4. My shared host just upgraded to my server to php5.2.0 and the function doesn't work.

If I call the file as a URL directly, it works. http://www.foo.org/cgi-bin/file.cgi?dir=/testperms=0755 file.cgi chmods the designated directory's permissions.

Anyone have any ideas? Thanks, Al What the heck are you trying to do? You want the cgi file to be executed? Or is there PHP code in the cgi file? If you want the first, you should look at exec() or system() or such. If there's PHP code, there's no sense in passing variables to the CGI script, and if you remove the variables it will work.
