[PHP] Migrating legacy code - changing session name
Hello List A client has asked me to migrate a few scripts that have been running merrily under PHP4 to PHP5.2. Part of these scripts have integration with PHPMyAdmin using the single sign-on and so they make use of the following code : session_write_close(); session_name(blah); session_start(); Now, assuming that prior to session_write_close(), I have a session that (amongst other elements) contains the following: $_SESSION['a'] = (an instance of Object A) $_SESSION['b'] = (an instance of Object B) $_SESSION['c'] = (an instance of Object C) After session_start(), I have the following : $_SESSION['a'] = (an instance of Object C) $_SESSION['b'] = (an instance of Object C) $_SESSION['c'] = (an instance of Object C) This does not consistently happen, only under particular circumstances (it seems to be a certain set of elements in $_SESSION triggers it). For instance, if I unset $_SESSION['b'] * prior* to doing session_write_close() - the behaviour stops, and the elements are retained. Has anybody seen this before? Vital Stats: PHP5.2 Apache1.3 FastCGI Sessions are stored using PHP5's default session handling.

Re: [PHP] If the first four characters are 0000, then do {}
Another technique could be.
$s = $mydata-restored;
if($s[0]==$s[1]
$s[1]==$s[2]
$s[2]==$s[3]
$s[3]==0){
do_work();
}
But I think you got the best solution already.

Hi.
I'm in the process of building a web service which incorporates the
ability for the server to inform the client that a particular call has
been superseded by another.
So, cut down (I've removed all the other details), ...
class ServiceDetails
{
/**
* Superseded by
*
* Details of the replacement service that is now available.

* @var ServiceDetails
*/
public $SupersededBy = Null;

When I try to use Zend_Soap_AutoDiscover() against this class, I get ...
Infinite recursion, cannot nest 'ServiceDetails' into itsself. (sic)
There has to be recursion, as there could be many levels of
supersedence, each one providing the details of their own replacement.
The call to return the service details read the requested
services/class constants. If there is a superseded entry, it creates a
new request for service details on the new class (the recursion).
If the value is Null, then there is no recursion.
I'm using ...
new Zend_Soap_AutoDiscover('Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex');
as the strategy as the service has arrays of complex types in the output.
If I use @var string and then manually replace the type in the WSDL
file from ...
xsd:element name=SupersededBy type=xsd:string /
to
xsd:element name=SupersededBy type=tns:ServiceDetails /
and use wsdl2php against this, it all _SEEMS_ to work OK.
So. Is this my best option? Or is there a way to do this that I'm missing?
Any ideas really.

Not yet! I'm on windows and I'm not confident enough to put extensions
I've built out on the live servers.
Also, it is using VC8 and I'm on 5.3 (VC9, x86, nts). So not tested.

Create a table and queue all pending mails in that then use windows scheduled tasks to perform the actual work if that is not a real-time mail. One thing to note, php on windows does't support specify username and password. But only hostname / IP Address and port only. I can not help much but just few more suggesions.

Re: [PHP] Re: Enforce a constant in a class.
2010/1/25 Colin Guthrie gm...@colin.guthr.ie:
'Twas brillig, and Richard Quadling at 22/01/10 11:33 did gyre and gimble:
Hello,
One of the aspects of an interface is to enforce a public view of a
class (as I see it).
Within PHP, interfaces are allowed to have constants, but you cannot
override them in a class implementing that interface.
This seems wrong.
The interface shouldn't define the value, just like it doesn't define
the content of the method, it only defines its existence and requires
that a class implementing the interface accurately matches the
interface.
Is there a reason for this behaviour?
_OR_
How do I enforce the presence of a constant in a class?
?php
interface SetKillSwitch {
const KILL_SWITCH_SET = True;
// Produces an error as no definition exists.
// const KILL_SWITCH_NOTES;
// Cannot override in any class implementing this interface.
const KILL_SWITCH_DATE = '2010-01-22T11:23:32+';
}
class KilledClass implements SetKillSwitch {
// Cannot override as defined in interface SetKillSwitch.
// const KILL_SWITCH_DATE = '2010-01-22T11:23:32+';
}
?
I want to enforce that any class implementing SetKillSwitch also has a
const KILL_SWITCH_DATE and a const KILL_SWITCH_NOTES.
I have to use reflection to see if the constant exists and throw an
exception when it doesn't.
The interface should only say that x, y and z must exist, not the
values of x, y and z.
Forgive the perhaps silly question but why are you requiring to use
constants here.
I appreciate the desire to use Reflection but why not just define a
method that must be implemented in the interface?
interface SetKillSwitch {
public function getKillDate();
public function getKillNotes();
}
By virtue of something impementing the interface, you know the methods
will exist.
If you want to make implmentation of classes easier, then define and
abstract class with an appropriate constructor and implementation:
abstract class SetKillSwitchAbstract {
private $_killDate;
private $_killNotes;
protected function __construct($killDate, $killNotes)
{
$this-_killDate = $killDate;
$this-_killNotes = $killNotes;
}
public function getKillDate()
{
return $this-_killDate;
}
public function getKillNotes()
{
return $this-_killNotes;
}
}
You can either put your implements SetKillSwitch in this class or the
derived classes depending on other methods you want to provide in the
base class.
I don't see why constants specifically are needed here. Rather than
using reflection you can just use instanceof or similar to tell if a
given object implements the interface or simply use the interface name
as a type specifier on an argument to another function/method etc.

With a constant, PhpDoc will pick up the value of the constant and
incorporate it into the documentation.
With a method, there is no way to know the return value. The type,
sure, but not the value.
Setting a constant is by far the simplest way to deal with this.
A method to return a constant is one method unneeded.
But, as I've said, I completely missed defined().
That's all I needed.
If the kill interface is applied to a class, then the parent class can
quite happily use defined(get_called_class() . '::KILL_SWITCH_SET') to
see if the class is defunct (or whatever).
Really. It was just the defined() call I missed. Everything is now working fine.

Just did a bit of hunting as I know I've seen something similar to what
you're asking before.
If you're on a Linux system, try this:
awk '!x[$0]++' inputfile outputfile
This seems to be the best way to remove duplicate lines and still
preserve the original order of the unique lines.

If this were me, I'd set up a mailserver on the web machine and send mail to it instead of using phpmailer to connect directly to a distant mailserver. The authentication between phpmailer and the local mailserver should be near instantaneous, and you can let the local mailserver deal with transferring mails in its own sweet time. I don't know if there's a mailserver included in XAMPP installations, but if so, I'd do that. In fact, if you're just sending simple emails, you could use PHP's built-in mail() function, which will connect directly to the local mailserver without further configuration. As another option, I have a simple SMTP script (Perl) that listens on port 25, accepts all forwarded messages and appends them to a text file. Since it doesn't actually do anything, it is all but instantaneous. I use it as a black hole relay MTA for development and test servers that can't reach the real world. If anyone is interested, let me know and I can send you a copy. It is adapted from something I found via Google.

First, an explode of the string to create an array, than I reverse it so
that the last ocurrence of the repeated part will always be last, after that
I apply array_unique, de-reverse it and implode it all back together as a
string.
Result?

Thank you very much !
@Ashley: It must be done in PHP, because it should run in any environment.
But thanks anyway, any help is apreciated: you just saw that there was a
much easier way than trying to use regular expressions or str_replace when
using arrays is considerably faster (especially because the $string won't be
a few bytes, it could range from ~5 bytes up to ~300+ KiB).

$store[B] = $var;
$var = new Foo(C);
$store[C] = $var;
var_dump($store);
This does not consistently happen, only under particular circumstances
(it seems to be a certain set of elements in $_SESSION triggers it).
For instance, if I unset $_SESSION['b'] * prior* to doing
session_write_close() - the behaviour stops, and the elements are
retained. Has anybody seen this before?

Re: [PHP] SQL question

Hey all,
I have an SQL query that's stumping me.
I have two date variables, $start and $end that are in mm/dd/
format and two database fields, start_date and no_donations. The
start date is mm/dd/ format and no_donations is an integer that
represents the number of months from start_date that donations will
be made.
So if start date is say 02/01/2010 and no_dations is 4 then
donations will be made four times from the start date for four
months.
What I need to do is come up with a query that will determine if the
start_date + no_donations falls within $start and $end.
But I'm pretty stumped. How can I convert start_date + no_donations
in the database to the date when the last donation will take place
so I'll now if the donations fall between $start and $end?
Any suggestions would be very help and appreciated,
Skip

Here's a snip-it of code from one of my projects:
$qry = SELECT SUM(amount) AS subtotal, COUNT(*) AS num
FROM transaction
WHERE product_type = 'video'
AND UNIX_TIMESTAMP(transtime) . strtotime($startd) .
AND UNIX_TIMESTAMP(transtime) . strtotime($endd) .
AND is_charged = 1
AND notes = 'Approved'
AND is_refunded = 0
AND transnum NOT LIKE 'TEST-PNREF'
AND product_id LIKE '$key' ;
$db2-select($qry);
while ($db2-readrow())
{
$rev = $db2-data[subtotal]; // this is the total amount
collected for the sale
$num = $db2-data[num]; // this is the number
of this type of sale
}
Clearly, you don't need everything there, but the timestamp notation
will give you better insight into how to use dates in your query.

Michael A. Peters wrote on 26/01/2010 06:04: I use seconds from epoch in the database simply because it works so well with the php date() function. If you need something where Julian day really is better, I assume it isn't that hard to convert between posix and julian day, though it seems odd to me that it isn't part of the date() function. It probably should be. When I do date comparisons in MySQL I use the to_days() function. What I need to do is come up with a query that will determine if the start_date + no_donations falls within $start and $end. In the given example one could determine that a month is always 30 days and then say to_days(start_date)+(no_donations*30) to_days(end). This would however be a very loose method. You could go for finding the number of days in the current month and substract that (10th. = 30-10), play with MySQLs left() function But Skip, as the others say, use a date class, since you're passing a php var on to the SQL anyway, then you could determine the exact days from start to end of donation.

right but the collection is built during iteration. one thing you could do
if you wanted it to *appear* as though the count was there at construction
is to subclass and iterate once in the constructor.
something like this:
?php
class SmartDirectoryIterator extends DirectoryIterator implements Countable
{
private $_iCount = 0;
public function __construct($sPath)
{
parent::__construct($sPath);
foreach($this as $oFile)
if($oFile-isFile())
$this-_iCount++;
}
public function count()
{
return $this-_iCount;
}
?

Re: [PHP] DirectoryIterator
right but the collection is built during iteration. So you're saying that if I add a file to the directory between the time I instantiate the DirectoryIterator and the time I'm finished iterating through, that file could be picked up? Or is the instance only going to contain a list of files in that directory at the time the object was constructed? thnx, Christoph

fwiw.., a quick peak at the code reveals the following:
. in the DirectoryIterator constructor it looks like the directory is
iterated at the C level
/* {{{ proto void DirectoryIterator::__construct(string path)
Cronstructs a new dir iterator from a path. */
SPL_METHOD(DirectoryIterator, __construct)
{
/* */
spl_filesystem_dir_open(intern, path TSRMLS_CC);
/* */
}
/* }}} */
. this iteration is implemented in some php stream code, but it looks like
some internal C structures are tracking the file count
PHPAPI int _php_stream_scandir(char *dirname, char **namelist[], int flags,
php_stream_context *context,
int (*compare) (const char **a, const char **b) TSRMLS_DC)
{
/* im pretty sure this is where the number of files is stored .. */

[PHP] Strange behaviour with str_ireplace()
Hi all. I found some unexpected behaviour with str_ireplace. To summarize, if the $replace term is a number, but formatted as currency with trailing zero's (34.50) the function drops the trailing zero. Example : $price=34.5; $message=You owe me #amount#.; $message1 = str_ireplace(#amount#,sprintf(%01.2f,$price),$message); $message2 = str_ireplace(#amount#,$.sprintf(%01.2f,$price),$message); $message1 will yield You owe me 34.4 $message2 will yield You owe me $34.40 So in other words, if the replace term can be interpreted as a number, it will be, including truncation of zero's. I didn't expect this, because as the function name suggests, it's a *string* replace. Fortunately I can just add a $ to the amount and make it work as a string, not a number but this would not always be the case. Is this by design, or is it a bug?

Re: [PHP] Speed of sending email .. can I put them in a queue rather than wait?

At the moment I'm runninng PHP on Windows and using the built-in sendmail equivalent packaged with XAMPP. It uses a remote SMTP that authenticates by prior logging into a POP account. The number of emails sent is very small. Each one is only sent after a user fills out a form and presses send. But there is a noticable lag of about 5 or sometimes 10 seconds after pressing send before the user sees the Mail sent page. I presume the reason for the lag is the time spent logging on and off a remote POP, then SMTP server, transferring the data etc. It would be better if this happened in the background - that is, the user could get on with doing his next task while the emails sat in a queue in the backgorund, being lined up and sent without PHP waiting for the process to finish. Can anybody recommend a good way of doing this? Is Mercury Mail going to help me here? The problem is that you are using Windows. Windows is a weak platform for what you are doing as it lacks of free solutions like those you find in Linux or any other Unix like OS. Under Linux practically every MTA has a queue. All MTAs queue messages by default instead of sending the message right away, except for sendmail. That is way faster than having your application to send messages to your MTA by SMTP as you are doing. If you are really stuck with Windows, if you can use Microsoft Exchange, you may use a faster solution. Exchange has a local pickup queue directory. You just write messages in that directory and leave them there. PHP does not need to wait for any delivery. Exchange will pickup the messages ASAP and deliver them. This is explained in this presentation. Jump to slide 11. http://www.phpclasses.org/browse/video/3/package/9.html If you want to use this solution, the MIME message package has a driver class for queueing messages in Exchange pickup queue directory .

Includes a rather simple ORM that ties into APC with it's variable caching abilities (I am aware of the limitations this provides now), reasonably simple MVC concepts and the ability to run multiple websites domains from a single installation. Other basics are there like XML reading etc etc. In hindsight, it's a little clunky now. But I was proud of it and I still am to a point :) Personally I believe any PHP developer who wants to be taken seriously should have written thier own framework :) I am actually planning another project, however it will use Zend Framework as a base. No need to re-invent the wheel, again, as fun as it would be :) Cheers -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ran this code (http://pastie.org/795983)
+1 for using pastie.org. :)
The result is,
array of 10,000
Array
(
[[]] = 5.66168689728

Almost 6 seconds to sort 10k array elements! Are you running this on a
Commodore64 ?!
Not that it probably matters, but I thought that it should be $o[$i]{0}
through $o[$i]{3}
Note the use of braces not square brackets for string character elements,
no?
Another thing I just noticed, is that we (that is Dan and I) should NOT
have used count()
This is bad form and wasted cycles.
for($i=0;$icount($o);$i++)
We should have just done a $elements = count($o) at the VERY top and used
$elements instead.
Does anyone know how PHP works internally? If I have 1M elements in the
array, does count() literally just zip through and $i++ them, or is there
some shortcut tally kept in the heap/stack/struct/memory somewhere for each
array?
Updated version:
?php
for ($elements = 0; $elements 100; $elements++ )
$o[] =
sprintf('%04d-%02d-%02d',rand(,),rand(00,99),rand(00,99));
#print_r($o);
echo array of .number_format($elements).\n;

At the moment I'm runninng PHP on Windows and using the built-in sendmail equivalent packaged with XAMPP. It uses a remote SMTP that authenticates by prior logging into a POP account. The number of emails sent is very small. Each one is only sent after a user fills out a form and presses send. But there is a noticable lag of about 5 or sometimes 10 seconds after pressing send before the user sees the Mail sent page. I presume the reason for the lag is the time spent logging on and off a remote POP, then SMTP server, transferring the data etc. It would be better if this happened in the background - that is, the user could get on with doing his next task while the emails sat in a queue in the backgorund, being lined up and sent without PHP waiting for the process to finish. Can anybody recommend a good way of doing this? Is Mercury Mail going to help me here? The problem is that you are using Windows. Windows is a weak platform for what you are doing as it lacks of free solutions like those you find in Linux or any other Unix like OS. Under Linux practically every MTA has a queue. All MTAs queue messages by default instead of sending the message right away, except for sendmail. That is way faster than having your application to send messages to your MTA by SMTP as you are doing. I agree that using a local MTA is somewhat faster then using a remote SMTP server, but I would have to say that the performance issue that he is reporting would be noticed by all that used remote SMTP servers if it were such a significant difference. I would argue that he needs to audit his code a little more. What he said was that the entire process from hitting the send button to showing the Mail sent page took that long. He said I presume the reason for the lag is the time spent logging on and off a remote POP, then SMTP server, transferring the data etc. I would suggest that he find out if it is or not. I would like to see proof that it is this portion of the script that is causing the slowness before suggest he change his server platform. He mentioned pulling data from a DB and generating the email dynamically. Maybe it is the DB that is causing some lag because of a badly structured SQL call. Maybe it has to do with the size of the data that he is requesting from the DB. Could it be the amount of data that he is submitting through the form? I would suggest that he try and replicate the process with the simplest of code. Even as far as removing the DB portion and sending hard coded data instead of stuff pulled from the db. Simply enough, I would have many things that I would suggest trying before telling someone to replace their OS. Just my 2cents... If you are really stuck with Windows, if you can use Microsoft Exchange, you may use a faster solution. Exchange has a local pickup queue directory. You just write messages in that directory and leave them there. PHP does not need to wait for any delivery. Exchange will pickup the messages ASAP and deliver them. This is explained in this presentation. Jump to slide 11. http://www.phpclasses.org/browse/video/3/package/9.html If you want to use this solution, the MIME message package has a driver class for queueing messages in Exchange pickup queue directory . Take a look at the test_pickup_message.php example script. http://www.phpclasses.org/mimemessage -- Jim Lucas NOC Manager 541-323-9113 BendTel, Inc. http://www.bendtel.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In a large hosting operation, this local MTA probably passes the mail for relay to a central MTA somewhere else in the host's network. There are a variety of reasons for this. Among others, it allows the hosting company to meter email and present a single set of credentials to foreign (offsite) mail servers. And in general, most hosting companies provide you with the location of the local MTA, in case you need it for Perl, Python, cron or other scripts. And PHP's mail() function will, by default, pass email to that local MTA. And moreover, most (all?) Linux MTAs on boxes like this don't block while they make connections.

[PHP] Magic Methods not working
I have a class which instantiates other classes, and has a magic method
like this:
function _get($classname)
{
return $this-instantiate($classname);
}
Obviously, the class also has an instantiate method which does what it
says.
Here's the problem: When I call the instantiate method, it works fine,
like this:
$db = $sc-instantiate('database');
But when I do the following, it *doesn't* work:
$db = $sc-database;
In fact it does not call the instantiate() method; I've placed a print
statement in the instantiate() method which fires at then end of the
routine. That statement doesn't fire with the above code.
The docs on magic methods are pretty slim, so I'm not sure what it is
I'm missing. Can someone enlighten me?

I seem that you should missed the required underscore _
It should the __get() but not _get().
Shall this help ?

[PHP] Reliable way to identify Ogg types?
When I use fileinfo on an uploaded Ogg file, the mime it returns is Application/Ogg which is almost useless. Is there a reliable php way, preferably without needing to execute shell commands, to positively identify a file as Ogg Theora or Ogg Vorbis?

Paul,
I seem that you should missed the required underscore _
It should the __get() but not _get().
Shall this help ?
Great Caesar's Ghost! You're right! Thanks.

Judging by the return, the OS is looking at the mime.types file, which (on my box at least) doesn't know anything more than this. In order to get what you want, I'm afraid you might have to open the file and examine its first few bytes using the data from /usr/share/file/magic, which has a more thoroughgoing understanding of ogg files.

Hi Micheal, One of way for this should be by checking the header of the file with its OggS magic number.

Subject: [PHP] Magic Methods not working
I have a class which instantiates other classes, and has a
magic method
like this:
function _get($classname)
{
return $this-instantiate($classname);
}
Obviously, the class also has an instantiate method which does what it
says.
Here's the problem: When I call the instantiate method, it works fine,
like this:
$db = $sc-instantiate('database');
But when I do the following, it *doesn't* work:
$db = $sc-database;
In fact it does not call the instantiate() method; I've placed a print

There are TWO underscores needed, not one.
__get()
Also, just to save you some time/grief, you might consider using my awesome
routines:
Put these in your base.class.php and extend it for all other classes.
Magic.
Oh no. I can't use those. The braces are in all the wrong places! (All
praise be to KR...) ;-}

Your regex is looking for case-sensitive matches, which given the example below, would preclude all of your list items (they all start with LI, not li.) Try using a case insensitive regex (e.g., $bl = preg_replace($pattern = /li[^]*style=DISPLAY: none[^]*/i','',$bl); (Note the i after the search pattern above.)

Concatenating your whole page to a giant string is silly and defeats the benefits (and purpose) of using PHP. I'm actually in the process of porting a HUGE site from that style to a more sane MVC and PHPish way right now. It makes me cringe every day I have to look at 'old' code. I suggest you read the question that started all this. I don't know why you should want to store a compiled page, but someone asked how they could do it, and I have suggested one way. PHP doesn't seem to have any problems with long strings (file_put_contents file_get_contents actually treat the contents as a string, and they don't slow down till the length grows past ~100k), so if you did, this would work as well as any other way. And however you generate a web page, it is effectively sent to the browser as a string (which can include linefeeds and all the rest) so this would work regardless of whatever fancy tricks you used to generate it.

Re: [PHP] Do you use a public framework or roll your own?
I read somewhere (can't find the link at the moment) that there's probably 2.5 frameworks per PHP developer. I know that when I started I was writing my own bits and pieces of two frameworks. One was function based and the other was OO based. I've since found the Yii http://www.yiiframework.com/ PHP framework and LOVE it. As someone that used to do assembly code programming on Pic microcontrollers with very little SQL background it was a bit of work to try and understand OO, MVC, ActiveRecord, etc.. But now that I have I'm much faster and more efficient. There's also the added bonus that being a Open Source project it is being worked on by lots of people and constantly getting better. So I'd have to vote twice. I've used my own frameworks, but now using a proper one. My 2c. -- Michael Kubler I believe in a better world. I support the Zeitgeist Movement http://www.zeitgeistsa.com.

I just want some hard cold numbers to look at. Do you use a public framework or roll your own? http://www.rapidpoll.net/8opnt1e I voted, but like others, my framework is more a collection of home grown tools which seem to have generic applicability. Some of this may be because I worked for many years in construction. You get used to certain tools and the way they operate, and you prefer them. For example, I won't use screwdrivers whose handles aren't covered with rubber over the plastic of the handles (Stanley and Klein brands). What I like about programming is that you get to build your own tools, just the way you like them. ;-} I totally agree. I started programming in the 60s on the CDC 3200/3600 series, which had an incredibly primitive version of Fortran. Then I started my own business and didn't program again until the late 70s, when I purchased a North Star personal computer running CPM under N*Dos. I started writing programs in assembler for instruments using microprocessors. The first thing I did was to develop a library of useful functions to do the sorts of things you need to do in an instrument. I started with some early microprocessor I never actually used, then progressed through RCA1802, 8080, 6800, and finally 80X86. Once I had got my library working, I found it relatively simple to update it from one microprocessor to the next. In the early 1980s I got a job as a lecturer in instrumentation and assembly language programming at a College of Advanced Education. I used my library to show the students how to program simple instruments, and in the process I learned a lot about how to design programs that students could use. In 1989 the computer labs were invaded by an accidentally lethal virus, which rendered the (non-standard) computers useless. Because I understood assembler, I was able to disassemble the boot sector, and work out how to remove the virus, and because I knew how students thought I could write a program which they could use to disinfect their computers at home. Because my library had nearly all the necessary functions I was able to write my program (which removed that particular virus) in a couple of days. I gave it to the students as shareware and at the end of the year I was able to resign. Nine years later we sold the program to Computer Associates, and I retired. I am back into programming because Microsoft (and many other software firms) insist on writing programs which make you do what they think you ought to do, not what you want to do. It used to be quite simple to use Mailmerge to manage a mailing list, but a couple of updates of Windows ago it became virtually impossible. I suspect that many of these public frameworks will do the same. And if you have written your own tools, you can easily change them if you don't like them. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
