There is no advantage in making use of some of these fancy new features in PHP 5, so I just don't bother. I couldn't disagree more. While I've yet to write any exception-based code, for me the magic getter/setter functionality in PHP 5's OOP is reason enough to switch all on its own. Not for me it isn't. I don't use getters and setters to access individual properties, I use arrays. Much simpler. Even if you don't want to write Java-style OO with crazy nested hierarchies (which you shouldn't be doing in PHP), true Singletons can be quite nice. The simplicity offered by passing objects as references is nice. But it is not a good enough reason on its own. There's a lot more to PHP 5's OOP than just let's add exceptions because Java has them, and that's not even counting the non-OOP improvements. Your point falls flat anyway. Yes, most PHP 4 code will keep on humming in PHP 5. That doesn't mean the PHP 5 features have no advantage, it just means that they're not mandatory for code to work in PHP 5. There's plenty that you can do in PH P 5 that you couldn't do in PHP 4, but if all you know is PHP 4 then you don't know what they are yet. If you bothered to read what I wrote you will see that I *DO* know PHP5 as the software I provide runs on both I have two PCs, one with PHP4 and one with PHP5 so I can ensure it runs on both. Your argument is logically false. I disagree. This topic is about the question are the new OO features in PHP 5 worth the effort of upgrading? to which my answer is *NO*. It is possible to write OO code in PHP4, and that code will run exactly the same in PHP5. Most of the new OO features in PHP5 are just fancy eye-candy which have very little practical advantage, so there is no point in modifying existing PHP4 code to take advantage of those features as it would be all cost and no benefit. -- Tony Marston http://www.tonymarston.net http://www.radicore.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Exceptions: I just don't see the big advantage. I've got errors and messages
bubbling up through object layers as it is, and exchanging that with a
wholly new structure seems more trouble that it's worth. I've read several
books on how cool PHP5 is, but the arguments for using exceptions seem to
boil down to Java has them. Nowhere have I seen good examples that really
show how well exceptions solve real problems, all examples seem to show are
that 5 lines of try/catch are somehow sexier than 5 lines of if/else.
One of the differences is that the if/else lines need to be in all layers
between where the error might happen and where it will be ultimately
handled. With exceptions, the try/catch can be detached (as long as it's
the right thing to do, of course).
What about performance?
Did you measure the performance impact of all those if/else's?
Exceptions are a special channel for errors, so your question is kind of
like is stderr any good? what about performance?
New OOP features: I can go through my code and mark all my methods as public
or private or whatever. No problem. But why would I? It will make classes
easier to understand when I look at them, but that's just convenience. What
are the performance benefits? I've not found a single mention of that
anywhere. What do abstractions and interfaces actually do, aside from
structuring my code better?
What do PHP4 classes actually do for you, aside from structuring your code?
What about performance? Wouldn't you be better off if you wrote all of your
program into a single file, all in global scope, using only builtin functions
and primitive data types? It would surely be faster, and you'd only lose the
convenience, no?
What major compelling reasons do I have to start using exceptions and OOP-5?
All the things you mentioned, and then some.
Someone else mentioned that PHP 5 is much less inclined to copy objects.
You still don't get the convenience of a private copy constructor, but
hey.
Another thing is destructors, so you're able to mimic C++'s powerful
// unlocked
{
mylock_t lock;
// locked
}
// unlocked
(not so powerful in PHP without anonymous scopes).
For example, a unit-testing library for PHP 5 called Testilence provides two
utility classes, a temporary dir and a temporary file (see mkdtemp(3),
mkstemp(3)). Both classes remove the underlying filesystem objects in their
destructors, so you can conveniently skip doing the cleanup yourself:
function test_O_EXCL_ThrowsOnExistingPath()
{
$file = $this-mkstemp();
$this-willThrow('RuntimeException');
new SplFileObject($file-path(), 'x+');
}
Also, notice how the code can omit checking for errors in mkstemp().
The return value is guarranteed to be the right thing, since any errors would
be signalled by throwing an exception, and that is handled By the caller of
this method.
How about iterators? You can have objects that look like arrays yet they take
much less memory:
$rs = $db-query($select); # query the db
foreach ($rs as $row) { # fetch the row
whatever($row);

Re: [PHP] Video question
You can put the video into a flash file and start playing the video with Javascript. If someone downloads the video, he will see a blank page, because of the missing start command from Javascript. Problem: If someone downloads the compleate page, he can watch the video. You can solve this by using complicated AJAX structures, but if someone tracks the AJAX-traffic it will be easy to start the video. In fakt there is no way to prevent videos from downloading.

Re: [PHP] Database Question
# [EMAIL PROTECTED] / 2006-12-20 00:01:29 -0700: I'm starting to log weather data to a database and I'm trying to figure out what's the best way to create the tables. The reports are coming in every minute, of every hour, 24 hours a day. Eventually, I'd like to do some calculations on the statistics, displaying daily values (which can be broken down to hourly), but then also daily and monthly averages. To me, it doesn't make sense to dump everything into one big table, but I can't figure out what's the best way to break it down either. Why doesn't it make sense? (That is a honest question: breaking the table makes no sense to me, so I'm really curious about your conclusions.) Keep in mind that the only data I have, is what comes in for that minute. The daily averages I have to calculate myself (later.) But I can't see one large table being very effective when it comes to calculating that stuff. Use materialized views. I use triggers and/or rules (in PostgreSQL) in situations like the one you describe. So, how should I break the tables down? Create a new table every day (20061219_data, 20061220_data, etc.) and insert all the values in it? Or, break it down per values (temp_table, humidity_table, etc.) and insert daily data in them? Imagine you have the data broken into monthly tables. I want to see average values from 2005-11-13 till 2006-02-16, what will you do? -- How many Vietnam vets does it take to screw in a light bulb?

There's no need just as there's no need for the while. Both are
conveniences. next() is more convenient than the because it's generic.
A single implementation can operate on an array, a DirectoryIterator,
SPLFileObject or MyDBResultSet.
Take a look at the STL[1] to get an idea what a set of generic
interfaces can do for you. Short answer: wonders!
Oh, and BTW, I do remember those days of painfully boring
if (!operation()) {
return some_error_indication;
}
whatever();
What we do in PHP 5 is use airbags and safety belts:
operation(); // throws on errors, taken care of by the caller
whatever();
BTW, fetchRow() is (IMO) better than next() *if used in while()* because
the code reads more naturally.
foreach ($rs as $row)
IMO wins over
while($row = $rs-fetchRow())
although this would win my vote:
foreach ($row in $rs) // pseudocode

[PHP] ob_start(ob_gzhandler) and error handling functions
Hi,
I include a php file at the beginning of every web page in this site.
This include file has an error handling function and starts output
buffering...
// Start of Error Handler
error_reporting(E_ALL ^ E_NOTICE);
ini_set('log_errors','1');
function ErrHandler($err,$err_string='',$err_file,$err_line)
{
// Do error logging thang
ob_end_clean();// Clear buffer
include('/path/incs/errors/errors.inc');// Output friendly error
page
exit();
}
set_error_handler('ErrHandler');
// End of Error Handler
It works great and the error handler kicks in if there is an error on
the page and outputs a friendly page instead. I really wanted to gzip
the pages by using ob_start(ob_gzhandler) but it doesn't work. I think
it is because of the error handler function trying to clear the buffer
(see the line ob_end_clean() which I assume becomes
ob_end_clean(ob_gzhandler) ). It says on the php functions page-
*ob_start()* may not be called from a callback function. If you call
them from callback function, the behavior is undefined. If you would
like to delete the contents of a buffer, return (a null string) from
callback function.
As I am new to this- I don't really understand what it is trying to get
at. Is there a way of me using my error handler and evoking the
ob_start(ob_gzhandler) ?
Thanks.

Re: [PHP] Are PHP5 features worth it?
All the XML things are new
Start with DOM. If you know DOM in Browser you can use DOM in PHP5.
AJAX Webapplications are not possible in PHP4. The experimental DOMXML
in PHP4 is NOT standard conform and has DIFFERENT syntax than DOM in
Javascript.
To retrive data from AJAX is simple.
$data=file_get_contents('php://input');
$dom=domDocument::loadXML($data);
Using an iterator, it is easy to put this data to a database.
$elements=$dom-getElementsByTagName('whateveryouwant');
foreach($elements as $element){
...
}
XPath also helps a lot.

You can use and provide XML Comunication (Webservices) with the same
skills as you do AJAX. Google for example has lots of Webservices that
are really useful. You can also connect to SAP Systems using XML for
Data transfer...
This opens a new world.
And finally PHP5 has much better XSLT support than PHP4. It's still
experimental, but it uses libxslt which is a really good thing.
--
If you do real javascript programming (not only document.write and
innerHTML) there are lots of things you
can do in the same way in PHP5 and javascript.
Learn it once and use it Client- and Serverside - that's the good thing
in PHP5.
The bad thing is, that all this nice new things are hidden in the online
documentation. If you search for getElementsByTagName (a DOM Method)
you don't find it. The same with XSLT.

Re: [PHP] Database Question
So you have two single table votes.. make this a third. I'm guessing that each time you collect data, it's going to be one of each piece of data every time. Temperature, barametric pressure, humidity, wind direction, etc. You're not going to have 5 things all the time and like 3 other things only sometimes. You'd want to split the data into separate tables if there was some data that was infrequently. Take a contact database for instance. You might have name, address, phone, birthday. But then maybe your company has forms that some people fill out. You wouldn't want all the data for a form that they may or may not fill out in the same table. You'd end up with a lot of empty spaces for the forms that some people never needed to fill out. So you'd put that data into a separate table and link them via a contact ID or something. As for efficiency, it's probably more efficient to keep everything in one table and do your statistics by using SQL to filter down by date and use aggregate functions like SUM() and whatever your database's version of AVERAGE and other math functions are. This way, it's handled very quickly and efficiently inside the database engine before it returns any data (which is pretty much the slow part of database access.. especially when there's a lot of data to return. Data return and uber-complex joins.. but even they can be more efficient than returning too much data). You could section your tables off by date if you want. 1/2 million records a year and you could get away with having a few years in one table, or keep it year to year. You gotta ask yourself though, if you're going to want statistics that cross multiple years or whatever boundary you set for your splitting. If so, you're really better off having it all in one table than trying to UNION the tables later (although that's viable too I guess.. it just gives me the willies.. bad experiences.. hah) Just some additional thoughts on top of what's already been mentioned. Oh yeah... buy a book and take it to the insert database type mailing list :) Good luck! -TG = = = Original message = = = Someone's going to tell me to go buy a book, I just know it. I'll ask anyway: I'm starting to log weather data to a database and I'm trying to figure out what's the best way to create the tables. The reports are coming in every minute, of every hour, 24 hours a day. Eventually, I'd like to do some calculations on the statistics, displaying daily values (which can be broken down to hourly), but then also daily and monthly averages. To me, it doesn't make sense to dump everything into one big table, but I can't figure out what's the best way to break it down either. Keep in mind that the only data I have, is what comes in for that minute. The daily averages I have to calculate myself (later.) But I can't see one large table being very effective when it comes to calculating that stuff. So, how should I break the tables down? Create a new table every day (20061219_data, 20061220_data, etc.) and insert all the values in it? Or, break it down per values (temp_table, humidity_table, etc.) and insert daily data in them? -- A ___ Sent by ePrompter, the premier email notification software.

[PHP] Trying to insert a large number from php to mysql
Hi I'm trying to insert the number 1970324970930197 into a mysql BigInt(20) field. If I do a direct insert from mysql command prompt and select the record I get back the same number. If I do this from PHP I get back 197032497093. Notice that the 197 at the end is not 000. When echoing the number in php it looks like : 1.970324970930E+15 so I'm guessing this is the reason why the 3 Zeros are added instead of the 197 at the end. How can I avoid this and actually pass the real number to mysql? thanks

RE: [PHP] get id field in table
gonzalo...
i didn't see your original post... but this might help... assuming some
things... not actual code, but you might get the idea.
assume your tbl looks something like
mysql db/tbls:
table foo
dog -int
cat -varchar(10)
etc...
id -auto generated
you can set up the mysql db/tbl to allow specified user(s) to access the
db/tbl, for the given port. specifiying/allowing user access is via the
'grant privilege' function for mysql.
in your php you need to connect with the db, as well as invoke queries that
are run on the targeted db
$db2_host -host system (ip address)
$db2_user -user for db (matches the grant)
$db2_passwd-user passwd
$db2_database -name of mysql database
// Make the database connection.
$link2 = new mysqli($db2_host, $db2_user, $db2_passwd, $db2_database);
//check connection/error
if(mysqli_connect_errno())
{
printf(connect2 err: %s\n,mysqli_connect_error());
exit();
}
$q4 = select * from foo where cat='ted';;
$res = $link2-query($q4);
while($row = $res-fetch_array(MYSQL_ASSOC))
{
$id = $row['id'];
}
this gets you the 'id'
to get a better understanding of how all this works, take a look at the
mysql site, as well as the sections of the php site that deal with
interfacing with mysql. you'll see the information on mysql/mysqli cmds, as
well as information on how to deal with the interfaces using procedural and
object oriented methods...
have fun!!!

RE: [PHP] Are PHP5 features worth it?
I think all this talk goes to show you that the differences between PHP4 and PHP5 are somewhat personal at this point in the game. Some people like the better OOP features of PHP5, some people think PHP5 is faster, some people like the XML/WebServices in PHP5 better, and many others (don't forget PDO, or exceptions). For the OP, I think it's really going to come down to what you think. Everyone's mileage is varying on this one. Here's my .02. If you go with PHP5, go with at least PHP 5.1.x, if not 5.2. I'm not sure how stable 5.2 is lately. I had heard of some issues, but they could have been from things most people don't do. I'm pretty sure that people don't install 5.0.x anymore, but 5.1 is a lot better (from what I've heard anyway.

But it is working like a lottery, sometimes yes sometimes no through WEB. When i test through shell, telnet or etc. it is fine, through web it sometimes outputs YES, sometimes outputs nothing (does not give NO), like it is not even connecting or getting no response at all. I have test mechanisms for valid connection and data send. So i get this crazy idea of caching for connections on web.

Thanks, Niels Hey, I'd like to be able to run at least two versions of php on one server and switch between them because if you've written a pile of php 4x code and need to switch to 5x, ( hosting service switches the boss you work for decides to switch , or what ever,) you have to go through all your 4x code and rewrite it to be compatible with 5x. So, the benefit of switching becomes an important consideration. While your converting 4x code to 5x compatibility you need two servers running, one with 4x interpreter and one with 5x interpreter. It really would have been nice if Apache and Zend got together so both version could be run by the same server based on something in httpd.conf and/or php.ini. What i have done, not to berate 5x is to write code that is compatible with both version. I have servers running both 4.3x and 5.1.2 and they run the same code just fine.

# [EMAIL PROTECTED] / 2006-12-19 19:05:23 +0100:
I'm writing a PHP program and I've got a number of concerns. The program
is about 20 KLOC at the moment, but will probably grow quite a lot.
I'm using OOP throughout, and I don't really have a lot of problems with
what PHP4 can do with OOP. PHP5 does have a nice feature or two,
eventhough none seems essential to my particular style of programming. I
don't mind using what PHP5 offers where it makes sense, but where's that?
Exceptions and new OOP features?
Exceptions: I just don't see the big advantage. I've got errors and
messages bubbling up through object layers as it is, and exchanging that
with a wholly new structure seems more trouble that it's worth. I've read
several books on how cool PHP5 is, but the arguments for using exceptions
seem to boil down to Java has them. Nowhere have I seen good examples
that really show how well exceptions solve real problems, all examples
seem to show are that 5 lines of try/catch are somehow sexier than 5
lines of if/else.
One of the differences is that the if/else lines need to be in all layers
between where the error might happen and where it will be ultimately
handled. With exceptions, the try/catch can be detached (as long as it's
the right thing to do, of course).
You're right, that is an advantage. I'll need to rewrite much of my current
code to make use of it, so that's not a high priority. More importantly I
have to start thinking in this new way to use exceptions properly.
What about performance?
Did you measure the performance impact of all those if/else's?
Exceptions are a special channel for errors, so your question is kind of
like is stderr any good? what about performance?
If two different ways of doing the same thing seem very similar, performance
may help me choose. It's true that I don't know anything about the speed of
all my nested if/elses, but that's not necessarily relevant if others can
tell me that exceptions are always hopelessly slow.
New OOP features: I can go through my code and mark all my methods as
public or private or whatever. No problem. But why would I? It will make
classes easier to understand when I look at them, but that's just
convenience. What are the performance benefits? I've not found a single
mention of that anywhere. What do abstractions and interfaces actually
do, aside from structuring my code better?
What do PHP4 classes actually do for you, aside from structuring your
code? What about performance? Wouldn't you be better off if you wrote all
of your program into a single file, all in global scope, using only
builtin functions
and primitive data types? It would surely be faster, and you'd only lose
the convenience, no?
I get your point, everything above assembler on the metal can be
considered merely convenience. In this case, however, there's a detail to
my question: I'm basically asking whether adding public/private to methods
will enhance performance. I could be -- I don't know about these things --
that the PHP processor could use such keywords to optimize the execution.
What major compelling reasons do I have to start using exceptions and
OOP-5?
All the things you mentioned, and then some.
Someone else mentioned that PHP 5 is much less inclined to copy objects.
You still don't get the convenience of a private copy constructor, but
hey.
Another thing is destructors, so you're able to mimic C++'s powerful
// unlocked
{
mylock_t lock;
// locked
}
// unlocked
(not so powerful in PHP without anonymous scopes).
For example, a unit-testing library for PHP 5 called Testilence provides
two utility classes, a temporary dir and a temporary file (see mkdtemp(3),
mkstemp(3)). Both classes remove the underlying filesystem objects in
their destructors, so you can conveniently skip doing the cleanup
yourself:
function test_O_EXCL_ThrowsOnExistingPath()
{
$file = $this-mkstemp();
$this-willThrow('RuntimeException');
new SplFileObject($file-path(), 'x+');
}
Also, notice how the code can omit checking for errors in mkstemp().
The return value is guarranteed to be the right thing, since any errors
would be signalled by throwing an exception, and that is handled By the
caller of this method.
That looks interesting, thanks.
How about iterators? You can have objects that look like arrays yet they
take much less memory:
$rs = $db-query($select); # query the db
foreach ($rs as $row) { # fetch the row
whatever($row);
}
takes much less memory is exactly the kind of advice I'm looking for. I've
found very few usable guides to such optimizations. Could you possibly give
me a specific example of an array and a similar object with this great
difference in memory consumptions?
Thank you for your answer,
Niels

There is no advantage in making use of some of these fancy new features in PHP 5, so I just don't bother. I disagree -- there are definitely advantages, the question is whether they are worth it. I think other answers in this thread bring good points to the table. Exceptions: I just don't see the big advantage.

I've read several books on how cool PHP5 is, but the arguments for using exceptions seem to boil down to Java has them. I don't use exceptions for the simple reason that there is no advantage in doing so. I have a perfectly adequate error handler (just lke you) so there is no pont in changing it. Java programmers can only program with exceptions simply because they don't know any better. Nowhere have I seen good examples that really show how well exceptions solve real problems, all examples seem to show are that 5 lines of try/catch are somehow sexier than 5 lines of if/else. What about performance? I agree entirely. Lots of extra code for absolutely no benefit. New OOP features: I can go through my code and mark all my methods as public or private or whatever. No problem. But why would I? Exactly What does all that effort buy you? Better functionality? Increased performance? The answer is nothing. You know that for sure? All it does is place restrictions on what other programmers can do when they attaempt to use your code. Lots of cost with no measurable benefit equates to a total waste of time. Restrictions do help stabilize the API. It will make classes easier to understand when I look at them, but that's just convenience. What are the performance benefits? There are no benefits, only restrictions. I've not found a single mention of that anywhere. What do abstractions and interfaces actually do, aside from structuring my code better? Abstractions are thought processes which help you to identify the essence of what needs to be done, so they are essential. Interfaces on the other hand are a total waste of time. Other languages have them because of deficiencies in those languages. PHP doesn't have those deficiencies, so interfaces are totally unnecessary.

[PHP] Poping array which has the matching value
Hi,
I wanted to search through the array and pop out the value which match my
search criteria. For example
If array has {a,b,c,d,e,f}
I wanna search for c and once I found it, took it out from the array.
So the result of the array after operation will be
{a,b,d,e,f}
If I do array_pop(); function it will only pop the last element inside the
array and the array will become
{a,b,c,d,e}
Anyway to search the desire element inside the array and took it out from the
array?

$letters = array('a', 'b', 'c', 'd', 'e', 'f');
$key = array_search('c', $letters);
$value = array_splice($letters, $key, 1);
$value[0] will contain 'c'
$letters will contain Array ( [0] = a [1] = b [2] = d [3] = e [4] = f )
