Hi All,
We've got a problem with our Ubuntu Linux machine sending HTML emails to
Outlook 2003:
It's an Ubuntu Server (uname -a
Linux CDR2-221 2.6.24-19-server #1 SMP Wed Jun 18 15:18:00 UTC 2008 i686
GNU/Linux)
with the newest version of Postfix installed as the Mail server.
Unfortunately, all emails sent as HTML, using the PEAR library for sending
email like so:
public static function sendEmail($fromEmail, $recipientsEmails, $subject,
$txtBody, $htmlBody = null, $ccEmails = null) {
require_once 'Mail.php';
require_once 'Mail/mime.php';
$message = new Mail_mime();
$message-setTXTBody($txtBody);
if (!$htmlBody) $htmlBody = str_replace(\n, br /\n, $txtBody);
$message-setHTMLBody($htmlBody);
$message-setFrom($fromEmail);
if ($ccEmails) {
if (!is_array($ccEmails)) $ccEmails = array($ccEmails);
foreach ($ccEmails as $cc) {
$message-addCc($cc);
}
}
//$message-addCc(m...@insiteorg.com);
$message-setSubject($subject);
$body = $message-get();
$headers = $message-headers();
$mail = Mail::factory(mail);
if (!is_array($recipientsEmails)) $recipientsEmails =
array($recipientsEmails);
foreach ($recipientsEmails as $mailto) {
$mail-send($mailto, $headers, $body);
}
}
arrive with only the plaintext part in Outlook 2003 (and only in Outlook
2003). All other email programs (Outlook 2007 e.g.) seem to work fine with
the formatting.
This only started happening on the Linux machine and works fine when emails
are sent by a windows host or another mail server from the ISP. So i suspect
it must be the setup of Postfix on that machine that is not quite correct.
Other than that, i get the following messages from PHP, apparently the PEAR
library has some (strinct)

There you go again. What's technically correct?
hiya tedd,
you mean to ask not technically correct ... I plead
that it's his statement that is not technically correct.
1. php does a soft comparison ('==' rather than '===') so the
results of each case expression is auto-cast to a boolean
(in the case of switch'ing on TRUE), ergo there is no 'as long',
statements will always resolve to a boolean ... only they may not
do it in a way that is readily understood by everyone.
2. the php engine specifically allows for 'complex expression'
cases testing against a boolean switch value ... not best practice
according to some but very much technically correct according to
the php implementation.
Good explanation -- I think the drum he's beating is that some of use the
switch without actually using the main expression within the control, such
as:
switch($who_cares)
{
case $a = $b:
// do something
break;
case $a 0:
// do something else
break;
case $a 0:
// do something elser
break;
}
The control works.
However to him, technically correct means:
switch($a)
{
case 0:
// do something
break;
case 1:
// do something else
break;
case 2:
// do something elser
break;
}
That's what I think he's advocating.
Cheers,
tedd

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. :)

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.
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
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;

Terion 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.

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.

[PHP] pear:Auth invalid username/password
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? John Corry

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. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Yes they will because there is no 'exit'.

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.

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.

Hi,

operation3(); // depends on 1 and 2 being successful

This didn't work as expected. After a bit of digging I found:

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?
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):
?php
$success = 1;
$success = operation1();
$success = operation2();
if( $success )
{
operation3(); // depends on 1 and 2 being successful
}
?
Alternatively you can do the following:
?php
if( 1 operation1() operation2() )
{
operation3(); // depends on 1 and 2 being successful
}
?
But really what you probably* want is the following:
?php
if( operation1() operation2() )
{
operation3(); // depends on 1 and 2 being successful
}
?
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:
?php
if( operation1() operation2() )
{
operation3(); // depends on 1 and 2 being successful
}
?
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

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?

[PHP] Visibility of class constant
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 :-( ). -- View this message in context: http://www.nabble.com/Visibility-of-class-constant-tp21803985p21803985.html Sent from the PHP - General mailing list archive at Nabble.com. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Throwing an exception seems to defeat output buffering
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 h1, but I do.
?
try {
ob_start();
echo 'h1You should not see this!/h1';
throw new Exception('h2This should be the first output./h2');
exit( 'Contents: ' . ob_get_clean());
}
catch (Exception $ex) {
exit('h2Exception:/h2' . $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
