Re: [PHP] Serving an image
What is the diference between using imagecreatefrompng() and readfile()? Any performance improvement? If you don't do any image minipulation, I would recommend readfile indeed. The differences being that imagecreatefrompng load the image into memory, ready to change it (overlay, rotate, crop, colours, .. anything), and readfile just sends whatever file you point it to back to the browser (or other output). Then again, if you all you're doing is sending an image to the browser; then why not do a redirect - or simply refer to the image directly? Wouter
Re: [PHP] Class not functioning
Allen,
Before you go with my static-approach, please do consider Shawn's registry
pattern suggestion. That's pretty sweet too ;-).
A little response to your long text, before I help you fix the bug. A static
property is basically the same as a regular property on an object. Only
difference is that they are not reset when the class is instantiated into an
object. They are just there.
Now, about your bug. The syntax for referencing a static property is a bit
weird - which has to do with the existence of class constants, which might
have set you off.
Notifier::notifyQueue would reference a class constant. The [] syntax is not
valid here, since a constant is - you got it: constant. And thus cannot be
changed.
Notifier::$notifyQ[] = 'div ... /div'; references the static property.
But... since notifyQ is a proptected static property, it is very unlikealy
that you'll ever actually write Notifier::$notifyQ. You add to this queue
from within the class itself, so therefore self::$notifyQ is a lot better.
Does that answer your question?
Btw; Shawn; Assuming that your Registry class holds objects, there is no
need have the ampersand in front of the get method or $object argument.
Objects are *always* references. And you might want to look at the __get,
__set and __isset magic.

Wouter,
Implementing your static idea was pretty easy, I was already referencing
Notifier with the :: operator in my other methods, however I am running into
trouble assigning new values to the static array.
I am getting a syntax error, unexpected '[' on this line of my Notifier
class:
Notifier::notifyQ[] = 'div class='.$message;
. . .
Any ideas why this is causing an error?
(note: I did try using $this-Notifier, and it said I cannot do what-not to
a non-object, can't remember the exact message at the moment)

Hey all (and Nirmalya, thanks for the help!),
I have a question that I just can't seem to find via Google.
I want to be able to add messages to a qeue whenever my classes complete
(or
fail to complete) specific functions. I think have a call within my html
to
my Notifier class to print all qeued messages (via a function 'printQ').
How do I access a globally instantiated class from within another class?
Example:
?php
// INSTANTIATE
$Meetgreet = new Meetgreet;
$Notify = new Notifier;
...
...
$Meetgreet-deleteSingle($id, 1); // This completes a function within
Meetgreet class. That function needs to be able to use the Notifier
function
addtoQ(), how would this be accomplished?
?
...
...
?php $Notify-printQ() ?

Any help would be appreicated!
Allen,
You have made a small typing mistake in function printQ() where you
would
like to checked the array for its existence. By mistake you have wrote
if
(isset($q)). But your array variable is not an freely accessible
array,the
array is embedded into an object. So, you have to write the like if
(isset($this-q)).
Another point, you can't add a message into the array by calling the
member function addtoQ() using scope resolution operator ::. If you
really
want to add message into the array, you have to call the member function
from within the object. (ie. $Notif-addtoQ('ERROR! There Was An Error
Updating The Database!', 'error');).

Re: [PHP] Security Issue
Karl,
Some simple checks on $contpath could solve your problem. Make sure that:
- it doesn't start with a /
- doesn't contain /../
- it doesn't contain a double slash //, or make sure the URL Fopen wrapper
is disabled:
http://nl3.php.net/manual/en/ref.filesystem.php#ini.allow-url-fopen
Usually $contpath = str_replace('/', '', $contpath); takes care of
everything.

I've got my own variation on this, came to use it to prevent overwriting

general purpose constants file, which defines a lot of constants which are
generally used a lot in my applications (file rootdir, DAY, HOUR, database

I define them using a simple conditional define function (if

if (isset($_SERVER['SERVER_NAME'])) {
$_config_file =

The included hostname specific config file would then define some constants,
and because they are already defined the default values from
constants.inc.php don't get set anymore.
Hope this is of help to anybody, it has certainly relaxed my deployment
process..

In config_dev.php I override anything defined in config.php that needs
to be different on the current server. The config_dev.php file is *not*
in source control so it doesn't exist in production but each development

environment.
There is a hit involved in the call to file_exists, but PHP caches it so
the effect is minimal.

Re: [PHP] Override parent class constants
I hate to disappoint you, but there's no real alternative. Same annoyance
with get_class() and __CLASS__ always giving you the class in which the
call is defined instead of the class which is actually being called when
dealing with static methods.
What you could do is define a protected static method in every subclass,
something like getConstant(), which always gives you the constant from the
correct class. I can't come up with a better solution than that. And I've
been trying to find one since the first version of php5 ;-)

No, what I had proposed was an alternate method to accomplish what
you said you wanted. But, it appears that my efforts and the demo did
not receive sufficient attention for you to understand what wass
being presented. Instead, you tell me that what I've shown you is bad
practice -- interesting.
First of all - I didn't ask the initial question ;-). Other than that, I
think our philosophies our basically the same. But when you say that you are
redirecting the user to another page, while you are actually including a php
script - that's not my understanding of redirecting.
You said that you wanted to remove login from the browser history,
which is screwing around with the user's browser and is clearly bad
practice.
Generally yes, removing a page from the browser's history would be
considered bad practice. However, we are not really talking about a page
here. What I understood from the initial question is as follows:
- http://www.site.com/ contains some login form, action of that form is
(for example) /login.php
- The user is sent to /login.php where the login is checked
- From there, the user either gets to a content page where it would
typically show welcome {user} or something, or back to the index page when
login failed
- As you see, login.php is not really a page but more of a 'pseudo page'
and therefore I cannot see any reason not to send a proper 303 header. see:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
My method simply stops the user from visiting the same page more than
once during a session and leaves their browser data alone -- nothing
bad practice about that!
AFTER my demo runs, if you repeatedly refresh the page you are
directed to, then certainly that would become annoying. But that
wasn't the intent, nor part of the demo, which you clearly didn't
read and obviously didn't understand.
As far as bookmarking the page, but of course you can bookmark the
page! Did you even try?
Oh well, so much for trying to help someone understand sessions. As
my mother often said No good deed ever goes unpunished.
I've got another one, There is no selfless good deed.
If you had simply said, I don't understand, please explain; or asked
a question or two; or said thanks, but no thanks, I'm going to do it
another way, then that would have been fine. But to say that the demo
I prepared for you exhibited bad practice, especially when you are
absolutely friggen clueless as to what it is doing, is a bit too much
-- I'll be sure to pass over your post in the future.
I don't think there wasn't anybody who didn't appriciate your suggestion.
Only thing I was trying to do was chip in my two cents. Again, I wasn't the
one who originally asked the question and I certainly am not friggen
clueless. I just came to think about what the teacher at my Flex course
from a couple of months ago said about good and bad practice. He said
there is none. If your solution works good for you, that's your good
practice. And if mine doesn't work for you, it's your bad practice - while
it is still my good practice.
Something however I am trying to fight against, if you let me put it like
that - is people approaching scripts as if they are pages. When you are
including a script that is usually called as a page into another script
you should be very aware for any clashes between variables. Another reason
why it may be easier to just put in a Location: header and call your script
as it was originally intended.

Re: [PHP] Cookies and sent headers
You best option would be to go through all of your include'd or require'd
files and make sure there is no whitespace before and after you open your
php tags. Those are often the cause for such problems. The easy way would
indeed be to use output buffering. In that case, put the call to ob_start();
on the first line of the file you're calling. You will still have to make
sure to not have any whitespace before your ?php opening.
To even bypass that, the output_buffering ini setting might be useful. Alter
it in your php.ini if you can, otherwise try your apache vhost configuration
or .htaccess. The syntax there is:
php_flag output_buffering On
Good luck!

Re: [PHP] Capturing shell command output.
You may want to look into shell_exec, which executes a command and returns
the output. If you're accepting arguments from user input, don't forget
proper use of escapeshellcmd and escapeshellarg ;-).
Something else that might cause your commands from failing, is that the
utilities are not inside apache's PATH - trying to call them by there
absolute filename can help out. Have you inspected your error_log? There
often tends to be a lot of useful stuff in there.

Re: [PHP] cant get if logic correct..
is_integer probably wouldn't work, since you're dealing with strings here.
Your best friend here would probably be 'is_numeric' which would return true
on both the string '1' as the integer 1 true. As well as 1.1 and '1.1'. The
only one solution I could think if would be:
preg_match('/^\d+$/', $stnr);

[PHP] HTML attribute / url safe wordwrap function
Howdy,
Yes, I've googled - and yes, I've searched the archives - but didn't
find a solution for my problem. Here's the deal:
On a website ppl can react on articles and post messages. The content
of a message is given to a function which parses it all, taking care
of long words which could mess up the interface. Or actually - it
does do that. It all wraps perfectly fine with the following lines of
code:
?php
$txt = 'website ppl can react on articles a
href=http://aspn.activestate.com/ASPN/docs/PHP/function.wordwrap.html;wordwrap/a';
$txt = preg_replace('#(a.*)((http|ftp|www).{13})(.*)(.{20})(/a)#U',
' $1$2(...)$5$6 ', $txt);
$txt = preg_replace('/([\.\?\w\)\(\:\',!\-\=]{30})/', '$1 ', $txt);
?
Unfortunately, this also breaks the weblink address. So, some
wordwrapping function that doesn't do that would be cool. So far, I
haven't been able to find it or create it myself.
Somebody out there feels like giving it a shot?

The webserver is Apache and it is running on a linux, I have googled and found that it is an Apache PHP issue but have yet to come up with a solution.

Re: [PHP] Fork PHP script X at a time.
Hi, I have a bit of a cold today so I probably would have figured this
out for myself eventually but hey ;-)
Right I have a script that I need to run around 90 times thru a cron job
but passing a different i.d. to it each time.
I have experimented with running all 90 at once and its a no go as it
just makes the server run to slow and the session cookies I use time out
(I am doing some libcurl things).
Also running them in a loop one at a time is no use because it takes
about 8 hours.
What I would like to do is fork off say 5-10 at a time and when one is
done start another one in its place, as they all take different length
of times to compleate.
Any clues at where to start? Here is my fork all 90+ code...
$sql = SELECT * FROM locations WHERE parent = '0';
$res = mysql_query($sql) or die ($sql.mysql_error());
while($data = mysql_fetch_array($res)){
exec(/usr/local/bin/php fork.php .$_data[id]. /dev/null );
}
You should be able to find out about the PID's for every forked
process, and use a loop (advisable with a sleep() in it) to see how
many procs are still running.. When the amount drops somewhat, spawn
another ..
Hope will get you somewhere!

My search on google didn't help me out, the docs say that it should

Please fella's, what am I missing?
The bottom of the strtotime() manual page where it says:
Note: The valid range of a timestamp is typically from Fri, 13 Dec
1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the
dates that correspond to the minimum and maximum values for a 32-bit
signed integer.) Additionally, not all platforms support negative
timestamps, therefore your date range may be limited to no earlier
than the Unix epoch. This means that e.g. dates prior to Jan 1, 1970
will not work on Windows, some Linux distributions, and a few other
operating systems.
A couple years ago when upgrading some web servers we found RedHat 7
had this issue, strtotime() basically didn't work and always returned
-1 on 'negative' unix timestamps. I have never used Fedora but it's
probably the same issue all over again. I know this isn't the answer
you were hoping for, but I wanted to share my experience.
so, basically my problem is confirmed to be existent - such a relieve
;) It's just that ppl I work for do want to be able to be born before
1970, cuz some are.
Mashed patatoes :@ - is there really no way to deal with this? Might
somebody have created a nice rpm of the kernel with t_*smth* set to 64
or 32 bits signed? I have full control over the server, so if i'd need
to make any changes, that is possible.

It's up to you. IMO, using single quote strings and breaking out when handling
variables is more readable than using double quote strings and escaping the
double quote (\).
I could still do with an example of how to put the information from the
form into the db though. As I have never done this before.
Plenty of tutorials out there.
First of all, you're making some pretty harsh coding style errors. For
the sake of compatibility, always make sure you're quoting
non-numerical elements in an array, thus: write $_GET['action']
instead of $_GET[action]. Imagine, for example, what would happen if
you've got some field named public and you're upgrading to php5? Or
when, in php 5.4 (just saying smth), action suddenly becomes a
keyword. You're stuck then with dead code.
Good practice is also to check whether your expected array entry is
actually set. I usually do smth like:
isset($_GET['action']) or $_GET['action'] = 'thedefaultvalue';
or
if (!isset($_GET['action'])) {
$_GET['action'] = 'thedefalutvalue'];
};
(both do the same, first one is just a lot shorter).
As adviced before, whenever you have to check if a certain variable
has a certain value, and if one of them is true, none of the others
will be true (which is the case with $_GET['action'] checks, usually)
- use the
if ( /* conditions */ ) {
} elseif ( /* other conditions */ ) {
}
method, rather than all seperate if's. I once changed this in somebody
else's code and found the script running about 5 (!!) times faster,
with about 15 conditions.
For inserting into the databas, mysql_connect() and mysql_execute()
are very good options. Or, if you're able to use the PEAR::DB package
I'd advice you to use that. It's more fun to do it that way, and will
help a lot if ever you'd want to change your database server from
mysql to something else (postgres, for example). Ow, and it also helps
a lot with any quoting problem you'd come up with.

[PHP] Problem creating a date before 1970 on Fedora
Howdy,
I would assume this to be a common problem, but as I wrote to this
list myself a couple of days ago I was only aware of it's existence on
windows systems. Here's some sample code
1 ?php
2 $date = strtotime('12 feb 1950');
3 print $date.': '.date('r', $date).\n;
4 $date = mktime(0,0,0,2,12,1950);
5 print $date.': '.date('r', $date).\n;
6 ?
And this is it's output:
-1: Thu, 1 Jan 1970 00:59:59 +0100
-3662: Wed, 31 Dec 1969 23:58:58 +0100
My search on google didn't help me out, the docs say that it should
work and I can remember me having used such code and got it working.
Please fella's, what am I missing?

[PHP] find quoted string within a string (more of a regex question, though ..)
Howdy, Thanks for the answers on my previous question, though it hasn't resulted in a quicker dirparsing.. Anyway, here's a next one. For my own reasons (can explain, would take long, won't till sbody asks) I want to match a quoted string within a string.

I've set up a regex that will nearly do the trick and now I'm looking for an enhancement (or replacement) that will work in all cases. Here's the code I use: ?php $str= the quick \brown fox ' jumps \' over \the ' lazy \dog; print Test String: $str\n; $regex = '/( ([\']) .*? ( (?!) \\2) )/x'; print Regex to use: $regex\n; preg_match($regex, $str, $m); print_r($m); ? (x modifier allows whitespaces in the regex). When run, it produces the following output: [output] Test String: the quick brown fox ' jumps \' over \\the ' lazy dog Regex to use: /( ([']) .*? ( (?!\\) \2) )/x Array ( [0] = brown fox ' jumps \' over \\the ' lazy [1] = brown fox ' jumps \' over \\the ' lazy [2] = [3] = ) [/output] basically, I think that I'll need to change the assertion (?!\\) to match only odd numbers of slashes - but I don't know how to do it.

[PHP] A somewhat faster alternative to is_dir and is_file?
Howdy, I've written some, kinda coolish, class that reads directories recursively with some simple calls. Yihaaa, .. (but I'm not the only one who has done that, I guess :P). Anyway, during the process of traversing a directory it checks to see if the something that was found is either a directory or a file, based on that it will do some things. Fine, works. But, now that I've got a directory with about 800 files to read I noticed that it takes the poor script almost two seconds to find the correct type of all the somethings. In fact, I timed it on a steady 1.71. I've tried to use filetype() on the something, but that took even longer - while looping through the directory without any checks finishes in 0.01 seconds. Now, for the question: does anybody know an alternative method on checking whether a something is either file or directory?

Hi all,

Does anyone have the regex to make sure an http address is full and without
error? like http://www.example.com
http://www.php.net/parse_url should do what you require. If all you want to
do is filter out the different parts of the url and check if they exist or
not.
Consider what you'd mark as a full url, do you want to accept ftp://
and such links as well.. quite generic, I'd go for smth like:
/^([a-z]+):\/\/(([\w\.]+)\.([a-z]{2,3}))(:(\d+))?(\/.*)?$/
Which would give you:
Array
(
[0] = ftp://www.example.com.com.uk:88/something/to/remember
[1] = ftp
[2] = www.example.com.com.uk
[3] = www.example.com.com
[4] = uk
[5] = :88
[6] = 88
[7] = /something/to/remember
)
Here're seme things I didn't take into account:
* double dots (www...example..com)
* double slashes (www.example.com//asdfasf//asdfasf)
* check for protocol validity, might wanna change the first part to
(ftp|http|chrome|.. any protocol you want to accept)
* I left everything after the first slash completely to the

First of all, I must say that from PHP5, the php (zend) engine does
support interfaces and implementing interfaces. So, maybe that's what
you're looking for... Anyway, now let's go on to helping you out with
your question.
Your approach is impossible. I'm stuck with the same thing, trying to
get the function name from a constant.. but there is a very nice way
of dealing with this. If you're running php5, it plainly works.
Earlier versions will need the (experimental) overload
(http://nl2.php.net/manual/en/ref.overload.php) function..
?php
class Obj {
var $gen = Array();
function registerFunction($name, $args, $imp) {
$this-gen[$name] = create_function($args, $imp);
}
function __call($n, $args) {
call_user_func_array(Array($this, $this-gen[$n]), $args);
}
}
?
after a registerFunction call, you can call your function as you'd
expect to call it. Everything I just wrote is untested, but I'm pretty
sure it'll work - safe for maybe some typo's.

Re: [PHP] ERROR
?

Can somebody helps me ? the error is that login don' t access and I don't found the
error.
Jorge,
can you supply somewhat more information on what you're doing? Where
do you set the $_SESSION['id'] value? Do you make a call to
session_start() on the page where you set $_SESSION['id']?
(though, from the look of this post - the problem is probably the use
of a capital I in Id instead of a lowercase one. Case mangling is a
very common error ..)
(also, I'd advise you to use the somewhat more elegant ?php
header('Location: http://www.domain.com/path/to/portada.php');
exit(0); ? way of redirecting.)

Re: [PHP] Multi-User Text-Editing
?php

Once there was a Bar
It had some Foo
Underneath its Foobar

$arr1 = explode('\n', $str1);
$arr2 = explode('\n', $str2);
$count = 0;
foreach ($arr1 as $line_num = $line) {
if (isset($arr2[$count] ($line === $arr2[$count]))) {

} elseif (!isset($arr2[$count])) {
echo Added \ . $line . \, was . $arr2[$count] .

$count++;
}
?
Then i'd get something like this:
Unchanged Once there was a Bar
Changed to It was red from It had some Foo
Changed to It had some Foo from Underneath its Foobar
Added Underneath its Foobar
Where the second, third and fourth line is wrong - i added a line
between There was a Bar and It had some Foo...
How should i do this?
Add something that goes to the next line in one file and stays on the
same line in the other whenver an addition is found - and use
http://nl2.php.net/manual/en/function.levenshtein.php or
http://nl2.php.net/manual/en/function.similar-text.php instead of !=
to see if a line has changed. I've never used it myself, but the
return value gives you a number indicating how different the strings
are. If they're very different AND the number of lines is not equal
you know for almost sure it's an addition.
Have fun finding the difference!

Re: [PHP] Re: Instantiating class, classname in constant
Quoting Catalin Trifu [EMAIL PROTECTED]:
?php
class Foo {
const Bar = 'Foo_Bar';
const Chocolate = 'Foo_Chocolate';
const Target= 'Foo Target';
}
$bar = new Foo::Bar();
?
Foo::Bar() is taken by php as a function call and then it tries to
instantate whatever that function returns.
This is quite logical behaviour since function calls always end up with
().
When you call
$bar = new Foo::Bar;
then the Foo::Bar is definetely refering to constant Bar in class Foo
Cheers,
Catalin
First of all: thank you Catalin for your thoughts!
Seems logical from that point of view.
According to the list if differences between variables and constants
(http://nl2.php.net/manual/en/language.constants.php) though, they should
pretty much work the same (no difference is mentioned). Thus, when both $bar
and Foo::Bar evaluate to the same value I would expect PHP to do the same
thing. Let me at least hope that the php team has considered many options on
how to deal with this...
If I do want to use the :: notation between PackageName and the actual name of
the class, I'm probably gonna be stuck using smth like:
?php
class Foo {
public static function Bar() {
return new Foo_Bar();
}
}
?
Or smth with the __call() function and an (iew) eval() call, since
call_user_func_array() doesn't work on constructors (or so I heard, haven't
tried it).

RE: [PHP] PHP IDE?
Yeah .. vim is my god too. You can do so many things with so little
keystrokes. And it basically has the best syntax highlighting I've ever
seen. With some easy tricks you can even let it highlight your own
functions. I haven't doen so, but I know it's possible :P... Also, it exists
on most servers so you can work directly on the server. Without having to
mess with (Samba) filesharing. Another advantage is that it runs both on
Linux as well as on Windows.
W.
(ps. Ahbaid or anyone else .. how can I get code to re-fold. I've setup my
vim to fold every PHP function and class, which works when I load te file.
But when I'm done editing a certain block, what do I do to make it fold back
in again?)
On zondag 14 december 2003 18:27 Ahbaid Gaffoor told the butterflies:
with folding you can fold your code in chunks, you
basically setup a start fold and an end fold and place
code between them, then you can open and close (fold) that
block of code as you need to or don't need to see it...
for example:
# {{{ PHP Code to do something...
..
..
1 lines of code...
..
..
# }}}
would collapse to one line when folded and look something like:
+ PHP Code to do something
then when you hit space on it it expands. (I use {{{ and }}}
as my start and end folds)
ctags allows you to build a dictionary of words which you can
hook into
vim, that way you can do tab completion on PHP words etc.
I also like to map keystrokes to coding templates for things like
functions, loops, declarations etc.
Everyone's got their own setup :)
Plus I always use a CVS repository for my work, so my routine
of, code,
test, commit is habit.
Looking at the responses there seems to be a lot of neat editors out
there, to each his own.

RE: [PHP] $GLOBALS containing itself!!!
On maandag 15 december 2003 10:24 Gerard Samuel told the butterflies:
Just curious about something I came across.
I was looking at the $GLOBAL array, to see what my script was leaving
behind. $GLOBALS contains a reference to itself.
Even though its a reference, whats the sense with that??
Once its global, why should it have to call on itself?
Im currently running php 4.3.4 on FreeBSD 4.9
Thanks
A script to try out -
?php
header('content-type: text/plain');
var_dump(isset($GLOBALS['GLOBALS']['GLOBALS'])); // returns true
// Prints out the $GLOBALS array
// including one reference to itself
// then starts another but quits with *RECURSION* var_dump($GLOBALS);
Well .. it basically just Contains a reference to every variable which is
currently available within the global scope of the script. The keys of this
array are the names of the global variables.. Since $GLOBALS itself is
global, that too is contained.
So:
var_dump(isset($GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB

']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB
ALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLO
BALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GL
OBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['G
LOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['
GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB

GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]));
Will still print out true. the displaying of *RECURSION* is to prevent, well
.. ehmm, recursively printing out the $GLOBALS array over and over again.
This is something new in PHP 4.0.4. Read the manual on page
http://nl3.php.net/manual/en/function.print-r.php:
Note: Prior to PHP 4.0.4, print_r() will continue forever if given
an array or object that contains a direct or indirect reference to itself.
An example is print_r($GLOBALS) because $GLOBALS is itself a global variable
that contains a reference to itself.

You kinda need to realize that
$String = 'FooBar';
print $String[4];
also prints out an 'B'. But this is adviced AGAINST because it is the same
syntax as you do for array elements.
To get a real array, do something like this:
$Array = Array();
for($i=0;$istrlen($String);$i++) $Array[] = $String{$i};
But if you have a string with char-space-char stuff, split(' ', $String);
would do too.

I'm sorry, but there are no other options. You can, though, ask your hosting

advice you to create one file to include in all other files, which sets
global options.

you'd be better off with a loop like:

Probably
include($this-page-javascript[$i]);
Is the problem. There's this thing in PHP that you can't do this thing with
referencing to an object property from within an other object. Or whatever
to call that. Sounds silly and stupid, but it bullies me too. Try this:
$Page = $this-page;
foreach($Page-javascript as $File) include($File);
or this (if you care about memory usage):
$Page = $this-page;
foreach(array_keys($Page-javascript) as $i)
include($Page-javascript[$i]);
Because php doesn't do reference thingies in a foreach loop, sadly.

I guess I don't really understand the question. I assume you realize that an include 'http://server.com/file.php' is going to send an HTTP request to server.com asking for file.php and if server.com is configured to execute php for file.php then what will come back across the wire is the result of php running the script in file.php.

Am not sure about the bug in yout script, but what are you trying to do? For
what I understand you are trying to find all customers who ordered Product
ID #1 and not Product ID #14? If that's right, simply fire:
?php
$Orders = mysql_query('SELECT *
FROM OrderTable LEFT JOIN CartTable on OrderTable.cart_id =
CartTable.cart_id
WHERE CartTable.product_index IN (1,14)
ORDER BY product_index ASC');
$Ones = Array();
while($Order = mysql_fetch_assoc($Orders)) {
if ($Order['product_index'] == 1) {
$Ones['cart_id'] = Array($Order);
} elseif {
($Order['product_index'] == 14) unset($Ones['cart_id'];
}
}
?
This will leave you with an array $Ones with all returned rows where the
cusomer ordered #1 and not #14. The trick is that I ordered on
product_index, so that I am sure that I'm processing all 1's first, and then
all 14's. With some more advanced order by tricks (this one's pretty simple)
you can probably leave out the enire where clause, and getting entire orders
matching the criteria you set.
Hope it helped you ;)

Hallo,

I'm working on Linux, Apache.
On my start-site the user can log in via inserting Username

After this login, he can change to his own user-directory
which is .htpasswd and .htaccess protected. Thats the reson
he has to insert his Username and Password again ;(
My Question:
Is there a way, so the user has to insert his data only once?
I've also tried it by doing a authentification like this first:
?php
if (!isset($_SERVER['PHP_AUTH_USER'])) {
Header(WWW-Authenticate: Basic realm=\My Realm\);
Header(HTTP/1.0 401 Unauthorized);
echo Text to send if user hits Cancel button\n;exit;

echo Hello {$_SERVER['PHP_AUTH_USER']};
echo pYou entered {$_SERVER['PHP_AUTH_PW']} as your
password./p; }
but it doesn't work for me, because when switching to the
userdirs, the .htaccess authentification window pops up again
(it is the same pwd and uid in the DB and the .htpasswd) ;(
Thank you in advance,
Michael

you could try this adding this method to each object you need

In the Load() method, you should determine what class you
need, and call $ret = $this-bless('classname'), and then return
$ret.
Then, instead of doing
$Thing-Load();
do
$Thing = $Thing-Load();
and have Load() return an object instance (either $this or the newly
blessed object).
This will maintain encapsulation and achieve the results you're
looking for.

Thanks Greg .. this comes pretty close to what I had done myself as a

don't return the blessed value, but overwrite the $this var. Which works.

This won't work. $_POST is always an array. If you want to go all the way of
re-posting the postdata, this is an appraoch that would WORK. I'm not saying
it's a GOOD appraoch (as others have said, it isn't :D):
echo input type='hidden' name='PreviousPostData'

and on the other one
$PreviousPostData = unserialize(stripslashes($_POST['PreviousPostData']));

There might be a design flaw in the scripts. Though what you mention is not
entirely true. I don't want to change the type of my object to change it to
another that is not related. They are related, very much. I'm changing an
instance of a 'superclass' to one of it's 'subclasses'. Here's the picture a
little more in detail, though still global:
- Two classes, SuperClass and SubClass
- One Table in the database
- This table holds some columns, one of them being instance_of
- my class SuperClass has a method -New($ID); which loads the row
from
the database representing the wanted object. At this point I do not
know
what the object should be an instance of.
- As soon as the Object finds out it's in instance of SubClass I
want
it to become an instance of this SubClass, because there's some
overloaded
methods that are to be called upon loading and stuff. And of course
some
others to be run at other points in the script ;)
Any design related remarks are just as welcome as suggestion on how to bless
the object.

[PHP] Blessing an object
Hi Folks
I was wondering (mostly because I came across some situations where I need
it) if PHP supplies any methods to bless an array or object to become some
other object. In perl, I can simply do:
my $SomeInstance = bless { item = 'value', 'Item2' = 'value2' },
'SomeObject';
And then if I decide that $SomeInstance should be an intance of some other
object:
bless $SomeInstance, 'OtherObject';
In PHP it would be extremely useful for for doing something like this:
?php
Class Foo {
Load() {
( .. )
}
};
Class Bar extends Foo {
}
$Thing = new Foo();
$Thing-Load();
?
In Load the object data is loaded from the database, and now imagine one row
to contain the subclass this instance of Foo should become. I then would
want $Thing to become and thus behave like an instance of Bar (if my
database row says so).
Hope this message wasn't too confusing ;)

I didn't actually try that, but I'm sure it's fine. I seems
to remove any extra data in the tags you want to allow. It's
good that you're still stopping me from entering such devious
and sinister code such as (.) (.) and bar...
Neither did I try my own code. And yes, sinister code like bar and
probably (.) (.) wouldn't come through the strip_tags function. Though I'm
not sure about the second one. (nor the first one, but a little more)
My point here is that I absolutely loath the strip_tags()
function and think it should be banished to the 12th circle
of hell, meaning mainly ASP or JSP.
I can think of no valid reason where anyone would require that
function.
I sometimes use it to allow certain HTML code to be entered in a form. For
example on a news site, where news editors are pretty familiar to HTML
without any desire to use a new markup language. PHP is a programming
language (as you no doubt know) designed and most used for web applications.
I think PHP would lose it's identity as such without direct HTML code
manipulating functions.
In any program, if I enter the string foo, then I expect
to either 1) Receive an error or 2) See _exactly_ that string
on any web page, email, etc, showing my string. I do not want
your program (speaking in general terms here) to remove
something from my string because it assumes it could possibly be
something bad.
Agree.
I'm against letting users enter HTML in their data, also. I'd
rather emply a bbcode type solution, turning [b] into b,
etc. This way, YOU set the rules and say the user can do
these _5_ things in this exact syntax. Otherwise you're held
at the mercy of the HTML and browser specs and hoping that
even just allowing b in the future won't have any security
issues. When _you_ set the rules, you win.
Usually agree for forum like applications. Not for HTML email sending
applications.
So, my suggestions:
1. Just run everything through htmlentities(). If the users
require advanced formatting, provide a bbcode solution.
2. If you just _have to_ let users use HTML like b and i,
then I'd use a solution similar to what you have above, but drop the
strip_tags.
$allowed_tags = array('b','i');
$safe_data = htmlentities($unsafe_data,ENT_QUOTES);
foreach($allowed_tags as $tag)
{ $formatted_data = preg_replace('/lt;' . $tag .
'gt;(.*)lt;\/' . $tag .
'gt;/Ui',$tag$1/$tag,$safe_data); }
Untested of course, but the only point that someone should
take away is that you should set the rules...
H ... Still considering a reply to that one ;)

You can do a simple str_replace() to convert lt;bgt; back into b, but you're going to have to do it for each case. Also by doing that blindly, you can end up with orphaned tags affecting the rest of your page (making it all bold, for example). How does bbcode make this easier or even different? It seems to me that lt;bgt; and [b] are a lot alike; they're both specific strings that you want to be converted to b. The difference is relying on the user to learn a markup language specific to your application. With no real benefit in doing so, this is an unnecessary complication. Slash uses regular HTML, and unlike any of our PHP equivalents (unfortunately), it is actually a nice CMS that isn't plagued with security vulnerabilities. So, my opinion isn't unique. Maybe I'm just the only non-Perl guy who thinks this way. :-) Your turn. :) Heh. :-) I don't think taking turns will help. We're probably both too stubborn to yield our respective positions. This isn't a new topic to me, and unless someone can bring up a point I haven't considered before, my opinion was made long ago. Chris I don't think there is ONE pbest solution in this. It all comes down to what kind of user you're expecting to use the application and what kind of input you would want to allow. To what extent those users are 'to be trusted'. And also what to do with invalid input. The way I see it, in HTML there are four major groups of tags 1) tags to separate sections (HTMLBODYFRAMESET) 2) tags that go into the header 3) tags to lay the structure of your PAGE (divtable) 4) tags harmless for the structure, used for text formatting only (biufont) In my experience, web applications that let users input some code only provide tags from group 4. Just let users markup their own text, but make sure the general site layout is not influenced. Too wide TABLE's or layers would push out parts of the webpage's structure, so not wanted. B tags are generally harmless. When you can trust your users to be of good nature, not WANTING to mess up the page, safe to allow those and strip_tags the rest ones out. If you cannot trust the users, and expect them to be wanting to mess up OR are expecting users without a lot of HTML experience, give them ubb'like things to mess with. Give them [bold], [green], [quote] and they are as happy as you are. Now let's look at allowing grin and what to do with entered table tags. A user would want it's grin text to be displayed as is, where a user entering disallowed TABLE tags is probably best of with either an ignored post or just not showing the TABLE text. First example: gt; and lt; are GREAT, I love them and do use them a lot. Second example: strip_tags() is my bitch. Then you'd have to think about what properties to (dis)allow. When preg_replace()'ing things like /(style|class|on[\w]+)=[']?[^' ]*[']? / To an empty string, you're getting safer and safer. So ..

Not like Gdanalf magic or anything. If you want Gandalf magic, I can give you some: ?=($WhoseMagic=='Tolkien'?'Gandalf':'Harry Potter')? Still I care more about compactness than the level of magic.

RE: [PHP] Why is the php loop, 'for()', so slow????
As a substitute for substr, you might want to give a regex a chance.. have
no clue if it's faster, but it might just be.
/^.{2}(.{0,8})/
would be your regex if you want to start at offset THREE and take out a MAX
EIGHT char string (remove the 0 and get ONLY EIGHT char strings). Not sure
if PHP sets $1, $2, .. vars, else give the optional third Matches param to

Well, should have make one long string to the $res_str variable a lot
shorter. :-)
It turned out that the for() loop isn't the slow part when you mentioned
about substr(). I tried out the while() loop and it is pretty
much the same
when the loop take over 5 minutes. So, it now seem to have to do with
substr() function. Yea, I'm not sure what hte best substitute of it would
be. In other branches off of this posting, someone said about using the
strpos(). I'm willing to give this a try but I have problem with this
because I have two !CDATA[[***]] tags in it and I want to use

Wow I didn't think you were going to post your whole program. :0
1. Are you sure the for() loop is the slow part?
2. As someone already suggested, calculating the sizeof() outside of the
loop should help a lot. Another enhancement is changing your for() to
while(). (This is a small enhancement but makes a bigger difference as
your iterations increase.)
REGULAR for() loop construct:
$iMax = 99;
for($iCnt = 0; $iCnt $iMax; $iCnt++)
{
}
OPTIMIZED:
$iMax = 99;
$iCnt = -1;
while(++$iCnt $iMax)
{
}
Like I said it's only slightly faster, but might make a difference
depending on your number of iterations.
3. I think what may be slowing you down is your substr() calls. Maybe
there is a substitute function that is faster? (I don't have any ideas
unfortunately.)
Let us know if you figure something out.
HTH,
Chris.

How to get the key of a specific index of array?
It seems that key($_POST[$i]) is a wrong syntax.
I've worked around like this:
$allkeys = array_keys($_POST);
$allvalues = array_values($_POST);
for($I=3; $I count($_POST); $I++) {
echo $allkeys[$I];
echo $allvalues[$I];
}
First of all, you said to use the first three values of the array for anoter
reason .. well the, what I'd do is this:
$FirstThree = array_splice($_POST, 0, 3);
Which will give you the first three elements of the array, and leave you
with a $_POST array you can do foreach with.
Second, to manually loop through an array, use:
http://nl.php.net/manual/en/function.prev.php
http://nl.php.net/manual/en/function.next.php
http://nl.php.net/manual/en/function.current.php
http://nl.php.net/manual/en/function.reset.php
http://nl.php.net/manual/en/function.end.php
Third, don't rely on the order your array elements are given to you by post
data. Rather just use foreach() and (ignore|do something else with) the
key-value pairs you don't want for this thing.
Fourth, I hope I'm not spoiling Jay Blanchard statement on how uncredibly

What you might want to do is this (though I doubt if you want to do it cuz it is pretty unsafe): forma action='execute.php?f=function_name' method='post' == execute.php == ?php if (isset($_POST['f'])) $_POST['f'](); ? I think you can do this with JavaScript, yes. No, Chris. For as far as I know you cannot even do this with JavaScript. Though I've never tried it. What you can do is use the 'onSubmit' event like this: form action='foo.php' onSubmit='return FunctionDeclaredInJavascript()' Where FunctionDeclaredInJavascript() is a function declared in JS (not in PHP). If it returns false the form will not be submitted, if it returns true the form will ..
