[PHP] accessing a property the static way
how can i access a property statically (without creating an object)?
is that possible at all?
i.e.
class foo
{
var $prop = array('some','defines','are','here');
}
$myVar = foo::prop;
OR
$myVar = foo::prop[0];
how can this be realized?
can someone help? is that possible with php?

i dont know if this really would solve your problem, but what i am using
sometimes is:
if( $save_data )
{
$id = save( $_REQUEST['data'] );
if( $id != false ) // is it a valid id?
{
header('Location:'.$_SERVER['PHP_SELF'].'?id='.$id );
die();
}
}
explaination: what it does is saving the $_REQUEST['data'] and on success, it
reloads the same page again but without the posted data to show exactly the
data that had been saved i use the $id returned by the 'save'-method, which
is the id of the data set that was saved
so reload or back buttons wont disturb
on reload, simply the same page with the GET-param is reloaded
and back button goes to the page before, since it seems the
"header"-redirection is not saved in the history
this only works for special cases:
- if you load the same page again, and want to show the entered data, it has
to be the same page for showing and editing the data
- showing data also has to work using $_GET-parameters, as this is what the
"header" function does
drawbacks are:
- only useful in some special cases
- browser gets contacted once more, than actually necessary ('header')

[PHP] help please - strange session behaviour on IIS with php4.1.2
i've written a simple script, which tests the session behaviour on the IIS,
since it didnt seem to work
the following script should increase the session-var $testVar and display it
but it always stays at the same value
can someone explain that? is that a bug?
also if i would increase $_SESSION['testVar'] it doesnt work.
i have been looking at the server and the session-file is also updated, but
not with the new values, only the timestamp is updated, it seems
session_start();
// make the session variable globally available
// we have register_globals = Off
$testVar = &$_SESSION['testVar'];
// init testVar to 1 or increase it
if( !isset($testVar) )
{
print 'set testVar to 1';
$testVar = 1;
}
else
{
print 'increase';
$testVar++;
}
// i can put session_register before
// or after the 'if' it always happens the same
session_register('testVar');
print $testVar;
the environment:
- IIS-Server5.0, WIN2k
- PHP4.1.2
- session.auto_start = 0
- register_globals = Off
i am using the recommended-php.ini, that's why register_globals is off

as far as i have experienced.
the type of the session variable is saved in the session too, so php
automatically realizes that "myCart" is an instance of
"ShoppingCart", you only need to be sure to have the class
"ShoppingCart" defined before you start the session, if i remember
right
that's at least how i do it and it works already for quite a while
very well :-)

[PHP] Tree class that can read/write/access/... DB and XML data
as i had announced a while ago on pear-dev that i have a tree class
which works on DB-data, now it is more enhanced and also works on XML
(for now it can only read but within a week or something it will also
be able to write)
short description:
-
this class reads data from either a db or xml file saves them in an
internal (array) structure (sounds kinda like DOM, doesnt it? i dont
know if it is alike, havent checked the PHP-DOM yet) and you can work
on those data
you can read navigate through the tree from ever point to any other
since every element has references to all its "neighbours" i.e.
$treeData [$id] ['parent'] ['next'] ['next'] ['child']
takes you to the parent's 2nd next element's child ... well just look
at the example page where you can try it
for navigation one can use ['next'], ['previous'], ['parent'],
['child'], ['children'] i think that's it
every element has an unique identifier, it's id, by which you can
refer to it and get information or data or apply functions to it i.e.
$tree->getPath( $id )
// very useful for navigating inside XML-structures
$id = $tree->getIdByPath( 'XMLNode / SubNode / SubSubNode' )
// or do it relative starting at $id
$tree->getIdByPath( 'SubNode3/SubNode4' , $id );
$tree->hasChildren( $id )
$tree->getChildren( $id )
and many more
to manipulate the structure you can use methods like
'add', 'remove', 'move' ... 'update' and 'copy' are not done yet
or even 'addNode' which can add an entire tree under a given element
i think that's mainly what it can do
it makes some stuff much easier, now tree structures are no problem
anymore for me, as it used to be a couple months ago
AND i can read XML(-config) files and simply retreive their data
without much action, see SimpleTemplate class for examples, it uses
XML-files/data to configure the settings for each template if wanted
please note,
that actually the class was meant to work on a DB-tree structure,
that's why its not optimized all the way for XML, but it works
extending the class to access nested-db-tables should be no problem
either
all those files can be found at
http://wolfram.kriesing.de/programming
might be useful in PEAR, i guess

[PHP] Template class
(just in case any of the people on PEAR-DEV will read this at all,
since everyone must be tired of the template class debates :-) )
i just wanted to say what i had to write, because i didnt see any of
the existing template classes/engines provide me with that
the main features are:
# compiling template class which (almost) only replaces '{' by , with pre and post filters
# uses indention to create the '{' and '}' for php-code inside the
template, so clean code is a requirement and no closing tags like:
{/if} are needed
# leaves all the power of php to you, not only the functionality the
template engine implements
# nothing to learn, just use '{' and '}' instead of the php-tags in
your template and indent your code properly
# the seperation of source and representation is all up to the
programmer (either this is good or bad)
# provides some default filter
a possible template
-
{if(sizeof($disadvantages))}
{foreach($disadvantages as $aDisadvantage)}
{$aDisadvantage}
{else}
no disadvantages registered yet :-)
-
the compiled code is nothing more than this
-
no disadvantages registered yet :-)
-
so you can see - easy to use, nothing to learn and should be fast :-)
feel free to have a look at
http://wolfram.kriesing.de/programming/
PS: BTW what was the decision on a multiple classes in PEAR
which do the same thing?

as you say, i guess the "local reference to the global var"
is the problem
at least i also forgot to define the "${$classNameY}" as global
if i do so then the following happens (see comments in code)

$curClass = ${"y"}; # this works, but it's not a reference :-(
