very true since this is the way it is taught in every book.  Php, however, 
allows for other uses that weren't "technically" in the original plan for 
this command from other languages.  The problem is I shave my head, so I 
have no hairs to split over this one.  :)

Actually, if you run your test, $var3 does NOT come out as "test2", it will 
return a "0" for that echo statement.  To get the results you want, it needs to 
be:
$var3 =& $var1;

What I typically do with that is make sure that if you are using

Also, I have gone through and put just: echo "1"; echo "2"; etc

What might help is if it's a small script, go ahead and post it to

More then likely it is a parse error within the page.  And no matter what error 
reporting you have turned on "within" the script will effect the outcome.

You have two choices.  Turn on error reporting from apache using the httpd.conf 
file, in your php.ini file, or with a .htaccess file.

This is the only way to get around parse errors without having error reporting 
turned on globally.

The other way is to cut/paste your code into sections.

Cut out a large chunk of it, see if it works, if it does, paste it back in and 
remove a smaller chunk,  rinse/repeat until your find the error of your
ways... :)

Better yet, use a IDE the does code highlighting.  This would point you to the 
problem rather quickly.

That's gives a error:

try this:
$file = get_file_contents('http://www.onflex.org/geo/xml/');
$file = utf8_decode($file);
$myxml = simplexml_load_string($file);

the above assumes the problem is because the file is really latin-1

quick note, using the service at onflex.org will always return you're 
servers ip address not the end users (as you're calling from server not 
clients browser) if this is what you want great, if not then you may 
want to try max minds geo ip.

I'm not sure what your setup is, but I get this frequently when testing on 
my windows server with IE

What I do to get the error is save a blank page over the one that is causing 
the problem.  Load it in the browser, then resave the probelem code, and 
refresh.  I almost always end up having left off a ; or } somewhere, and it 
just won't report it till I refresh like this.

Hope that helps.
Frank.

[PHP] pear:Auth invalid username/password

[John Corry]

I'm using Pear Auth on several sites and am looking for suggestions on the
best way to implement error reporting on a failed log-in.

Currently I'm using a function that checks if the posted username is in the
users table...and if the password is a match. Auth logs the user on if
so...but if not it takes manually running the queries to generate the right
failure message.

Is there a cleaner way using error messages generated by the getAuth()
method or another method in the Auth class? I didn't see anything in the
docs...but it seems like an obvious bit of functionailty I would sort of
expect it to be included.

Anyone know of such a thing?

You mean if it's a valid username but not password?

I'd say don't. While it's a little nicer for your users ("hey, your 
password was wrong") - it's also a lot easier for attackers. "Hmm, that 
means it's a valid user, lets see if we can brute force the password".


"Username or password are incorrect" - an attacker has no idea which bit 
is wrong. You could force a user to use their email address as their 
username to make it easier to remember.


Depends on the app & audience I guess, if it's an internal only app - go 
with #1 (no idea about Pear Auth though), if it's public, there's no way 
I'd say your password is wrong, just provide a "forgot password" feature.

Yes they will because there is no 'exit'.

http://us.php.net/manual/en/language.operators.bitwise.php

You're doing an AND, then assigning it when you say &=.  Think of it
like doing something such as .= or +=.

You might also be confusing &= with =& where =& means assign by
reference.  This used to be very necessary when dealing with php4 oop,
but isn't so much anymore.

Depends on the load on your server. If you're getting a billion
requests per second, then it may well be cause for concern. Either way
you can define a function called "__autoload" that gets called when a
class is about to be instantiated. This function can then load the
correct library. On demand as it were.

Show the code where your session vars are written and I would prefer using

The Drupal coding standards say to exclude the closing ?> on files for the same

Re: [PHP] Boolean Assignment Operator

[Gavin Hodge]

Wow, thanks for the quick replies!

I hadn't realised that & was purely a bitwise operator.

In the strongly-typed Java world, & works as a non-lazy (exhaustive?)
boolean operator so it has to return a boolean for boolean inputs.
Thats the difference here, and Robert got it in one.

Gavin.

PS. A code restructure isn't really appropriate here. The original
executes several SQL statements inside a transaction and needs to know
whether to commit or rollback at the end. The example was simplified
to get the point across but thanks for the suggestions.

Operators are listed here:

http://www.php.net/manual/en/language.operators.precedence.php

The compound assignment bitwise operator isn't documented explicitly but
the general idea can be found here:

http://www.php.net/manual/en/language.operators.assignment.php

The === operator is for mathcing values AND data type. By performing a
bitwise & you are returning data of type integer. As such comparing
against boolean true fails when you use ===. Instead what you should do
is the following (both for logic and succinctness):



Alternatively you can do the following:



But really what you probably* want is the following:



Why is the last one the one you probably want? Because if operation1()
fails then operation2() won't be evaluated at all... this is usually
what you want, but sometimes running operation2() is required to change
some state someplace, in which case you can use:



Of course bitwise only works if they return the same bitfields. For
instance if operation1() returns 1, and operation2() returns 2, then the
bitwise anding of the values would be false since different bit
positions are being combined.

Cheers,
Rob.

Hey,

never heard of the "|=" operator. So I think php does not support it.
I cannot say how "&=" works in Java or C# but as of php it works like that
(IMO) (reference instead of copy):
$var1 = "test1";
$var2 = $var1;
$var3 &= $var1;
$var1 = "test2";

echo var1; // "test2"
echo var2; // "test1"
echo var3; // "test2"

No, =& forces reference assignment. &= works as you have written.

[PHP] Boolean Assignment Operator

[Gavin Hodge]

Hi,

I'm fairly new to PHP, having migrated from the Java / C# world.

I wrote some code similar to the following:

$success = true;
$success &= operation1();
$success &= operation2();

if ($success === true) {
operation3(); // depends on 1 and 2 being successful
}

This didn't work as expected. After a bit of digging I found:
* The &= operation isn't mentioned anywhere in the PHP documentation
* The &= function seems to work as expected, however the following is
observed...
   $success = true;
   $success &= true;
   print $success == true; // outputs 1
   print $sucesss === true; // no output
* The 'or' assignment operator |= causes no errors but doesn't work.

Can any PHP gurus explain why the &= operator works at all, and why
=== seems to fail afterwards?

Cheers,
Gavin.

Re: [PHP] Boolean Assignment Operator

In Java / C# / C,
$bool &= $anotherBool;
is shorthand for
$bool = $bool & $anotherBool;

So &= forces a reference assignment?

[PHP] Another matching question

[Ron Piggott]

How do I tell if 

words_from_the_well 

is not the value of $page (whether it is the entire value of $page OR
within the value of $page)

So far I have come up with the following, but it doesn't deal with when
$page is only within the value of $page

if ( $page <> "words_from_the_well" )  {

The <> comparison operator won't work in PHP. What you want maybe is
something like this:

if(!strstr($page, "words_from_the_well"))
{}

[PHP] How can I do the opposite of property_exists(), maybe a creat_property() in PHP5?

[Daevid Vincent]

Is there a way to create a new property via PHP 5.2.4?

I get a hash back from an authentication server. I'm not guaranteed that
someone in another department won't add new key/values to the returned
hash/array. I'm trying to work around that part gracefully so that the
code doesn't blow up on a customer in such an event. The main try/catch
will suppress errors already, but I thought it would be nice to be able
to handle this stuff automatically rather than constantly updating a
User.class.php file all the time.

"creating new property this->oraclecustomerid with 1122"

but when I try to set the value with the $this->$pkey = $value; 

It triggers __call() which then triggers __set() which throws my
BadProperty exception.

How come $this->$pkey = $value isn't creating/setting a property? 
Or how do I do something like create_property($this, $pkey);
so that I can then set it via $this->oraclecustomerid = 1122 or
$this->set_oraclecustomerid(1122) ???

 $value)
{
//try
{
$pkey = strtolower($key);
//[dv] this is sort of a hack to 
"automatically" create a new
property/variable
// for 'new' hashes key/values we may 
not know about.
// It's really designed to supress 
errors and they really should
be added to this User.class.php properly.
if ( !property_exists($this, $pkey) )
{
echo "creating new property this->$pkey 
with $value\n";
$this->$pkey = $value; //THIS BLOWS UP 
ON THE __set()
echo "this->$pkey = ".$this->$pkey;
}
else
{
$class_variable = 'set_'.$pkey;
$this->$class_variable($value);
unset($user_data[$key]);
}
}
//catch (Exception $e)
{
//echo $e->getMessage()."\n";
}
}

//should new fields be returned in the $user_data that are not
accounted for above...
if ($_SESSION['DEVELOPMENT'] && count($user_data))
{
echo "";
}

//THESE TWO LINES FATAL ERROR ON THE __get():
echo "this->oraclecustomerid = ".$this->oraclecustomerid;
echo "this->get_oraclecustomerid() = ".$this->get_oraclecustomerid();
}

[PHP] Visibility of class constant

[leledumbo]

I got a weird behaviour of class constant. Suppose I have Index_Controller
and Another_Controller classes, both extending Controller class. I define
some constants (let's assume I only have one, call it MY_CONST) in
Controller class to be used by its descendants. In Index_Controller, I can
freely use MY_CONST without parent:: needed. However, this isn't the case
with Another_Controller. Without parent:: I got notice Use of undefined
constant MY_CONST - assumed 'MY_CONST'. How could this happen and what's the
correct behaviour? It's actually nicer to have it without parent::, assuming
that constants have protected visibility specifier (which isn't possible
AFAIK :-( ).

[PHP] Throwing an exception seems to defeat output buffering

[Leif Wickland]

I would expect that if I turn on output buffering, echo something,
throw an exception,
and catch the exception, nothing will have been actually output.  That
doesn't seem
to be the case.  Throwing an exception seems to defeat output buffering.

In the following code, I would not expect to see the , but I do.



You should not see this!';
throw new Exception('This should be the first output.');
exit( 'Contents: ' . ob_get_clean());
}
catch (Exception $ex) {
exit('Exception:' . $ex->getMessage());
}



I'm exercising that code on PHP 5.2.4 and 5.2.8.

Does anybody know why throwing an exception seems to override
ob_start(), flushing the buffered output?  Is there a workaround?

Thank you,

Leif Wickland

Hey,
well, $this->$pkey is wrong syntax. Try $this->pkey = $value
