[PHP] Re: php mySql question
Sure that your php.ini is located correctly? I have installed php 5.0.4 on my windows 2000, IIS 6.0 server. PHP works but when I try to connect to MySQL I get the Fatal error: Call to undefined function mysql_connect(). I have uncommented the line in the php.ini file that says 'extension=php_mysql.dll'. I have path variables set for both c:\php and c:\php\ext. One very peculiar thing that I noticed when I ran phpinfo() is that it shows the extension_dir is set to c:\php5 even though in my php.ini file it is set to c:\php. I have a feeling that this is where the problem exists. Any advice would be appreciated.

Re: [PHP] Object Inheritance, get_class() and a static function call
Hello Jochem,

Okay.

I need the classname to register variables in the session. It's
complicated. There are a lot of inheritences. Please take a look at the
code:
class onObject {
// ... }
abstract class onAplObject extends onObject {
protected static function registerVariable($key, $value) {
$theRealClassName = ???;
# $theRealClassName = get_class($this);
# output is --> Undefined variable: this in ...
# $theRealClassName = get_class(self);
# output is --> Notice: Use of undefined constant self ...
# $theRealClassName = __CLASS__; # =>
$theRealClassName=="onAplObject"
# $theRealClassName = debug_backtrace()[1]['class'];
# => $theRealClassName=="onDbTableEdit"
# $theRealClassName = debug_backtrace()[0]['class'];
# => $theRealClassName=="onAplObject"
$_SESSION[$theRealClassName.'_'.$key]=$value;
}
}
class onDbTableEdit extends onAplObject { public static function show() {
self::registerVariable("listsort", "id");
}
}
class onUseradmin extends onDbTableEdit {
//
}
onUseradmin::show();

Re: [PHP] Object Inheritance, get_class() and a static function call
Hello Jochem,
either you tested some different code to what you posted above OR
(your build of?) 5.0.3 is borked.
sorry, I didn't tested the code at all, because my code is more complex.
I just tried to show the problem.
class ClassA {
public static function getClassName() {
return get_class($this); // [1]
// or [2] return get_class(self);
// or [3] return __CLASS__;
}
}
class ClassB extends ClassA { }
echo ClassB::getClassName();
I am searching for a function to use in line [1] so that the script's
output is "ClassB".
I tested this on 5.0.2 and 5.0.4 and both did exactly what I expected,
namely
output nothing - $this is not defined when you call ClassB::getClassName()
(because you make a static call) so nothing is the only logical output.
my fault, again, sorry. I jumbled the different outputs. I understood
that this behaviour is coherent.
maybe you mean:
class ClassA {function getClassName() { return get_class($this); }}
class ClassB extends ClassA {}
$B = new ClassB();
echo $B->getClassName();
which _does_ work but is fairly pointless because you
already know the classname in order to be able to create the object
in the first place.
that's true. I don't want to use this. I just checked it.
I don't really see what the problem is, can you give some
more real world detail on what you are trying/want to do?
otherwise (re-)read this chapter:
http://php.belnet.be/manual/en/language.oop5.php
http://php.belnet.be/manual/en/language.oop5.static.php#48234
is better. but it seems that even debug_backtrace() is not what i'm
looking for...
... if you're _really_ into generic code then the reflection API
no, no generic code. ;)

"The double colon, is a token that allows access to static, constant,
and overridden members or methods of a class."
Of which none of yours are (at least not in the code posted)
Sure! It's the first one: i'm calling a method of the class without
instantiaton. it works even though the method isn't declared static.
maybe this is the fault!?
class ClassA {
public static function getClassName() {
return get_class($this); // [1]
// or [2] return get_class(self);
// or [3] return __CLASS__;
}
}
class ClassB extends ClassA { }
echo ClassB::getClassName();
> Wouldn't get_parent_class() work in this situation?
No, because there is no parent class of ClassA and im searching for the
name of the derived class.
Maybe i will found the solution on
http://php.belnet.be/manual/en/language.oop5.static.php
Still reading...

[PHP] Object Inheritance, get_class() and a static function call
Hello,
following code won't work in the expected way:
class ClassA {
function getClassName() {
return get_class($this); # [1]
}
}
class ClassB extends ClassA { }
echo ClassB::getClassName();
this script echoes "Object" instead of "ClassB". but i would like to
return the classname of the derived class without writing the method again.
this will work:
B = new ClassB();
echo ClassB->getClassName();
i tried to use line [2] instead of [1]
return get_class(self); # [2]
but this only returns an empty string.
is there any solution for my problem?
i'm using PHP Version 5.0.3 (with Apache 1, Windows XP)
greetings

[PHP] Interesting phpversion() thing.
I just upgraded to 4.3.5. I double checked and made sure I put everything in the right place. If I run php or php-cli from the command line and the script has phpversion() in it, it returns the correct string, i.e. 4.3.5. If, however, I pull the same script up in a browser it gives me 4.3.4. I've tried everything, clearing caches, etc. Can't seem to get it to do what I expect. Any one else see this?

Re: [PHP] Detecting Binaries
That's not bad, but I found a way to do it simply using chr() and
passing it a value. It turns out the if I go 0-31 Almost nothing will
get through. Even the simples html has something in there from that
list. However, by just looking between 14 and 26, one more than carriage
return, and one less than escape, it worked really well. I crawled a
site with a large number of jpg, gif, mp3, wav, and pdf files. Of the
100's of binaries there only one pdf got through. Not a bad record. I
also found that in order for this to work I have to process the URLs.
This makes things really slow so I'm going to have to use both this and
the "check for extension" function together. Still, I can worry a lot
less about getting my index weighted down by binary files. The code is
pretty basic at this point, but here it is:
// Check for binaries
$ckbin = 14;
while($ckbin <= 26){
$ck = chr($ckbin);
$cbin = substr_count($read, $ck);
if($cbin > 0){
echo "Killing off binary file URL: $url\n";
$kill = mysql_unbuffered_query("DELETE FROM search WHERE
url_id='$url_id'");
continue 2;
}
++$ckbin;
}
I know it looks kind of funky out of context, but it works really great.

Let me rephrase - check for the existence of characters 0 through 31
and count how many there are. Set a percentage weight yourself and
figure out in your script if you deem the quantity too many or too
few.
The count_chars() function will be absolutely ideal for this.

Opening a binary file into a hex editor will show you this. Your brain can determine if the codes in-front of you are "English" or not, but from a pure logic point of view that's a little harder. Also bear in mind that on Unix ALL files are binary files. It is up to you to determine the type of the file contents as you see fit. For example you can check for line-terminated data. It would be wise to check for characters from 0 to 31, if they appear then it's almost certainly (but not guaranteed) binary. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Detecting Binaries
Yes, and in fact that is what I am doing now. This is a spider bot though, so I'm having to think of every single type of binary file that could be linked to on the web. So far I'm up to 28 with no end in sight. What about a .com file? I can't omit links that end in .com can I? That would be counterproductive to say the least. Also, the function that does the checking just keep getting longer and longer, which makes the spider go slower and slower. Granted, the thing is pretty fast if it has enough BW to work with, but still. This could eventually turn into a script killer. Detecting whether the stream from file_get_contents(), or fopen() for that matter, is binary or not and going with that result is the elegant solution to this problem. There has to be a way to do it.

[PHP] Triggers & events with objects
Hi,
I would like to do the following
When an objects method is called like this:
$test= new Testclass;
$test->someMethod ($someArgument);
I'd like to have an event handler outside Testclass to
log this event, like this:
function event_handler ( $method_name, $obj [, mixed parameter [, mixed...]]) {
switch get_class($obj) {
case "testclass" :
// ...
if ($method_name == "someMethod " {
// ...
}
break;
}
}
Is that possible in any way?
TIA, Axel.
