There are two ways of accomplishing what I think you're trying to acomplish.
These ways are known as the right way and the wrong way.
the right way results in an array like
$func = array(0 => 0, 1 => 1, 2 => 2 ...)
The wrong way results in a set of variables like you described
$func1 = 0
$func2 = 1
$func3 = 2
$func4 = 3
$func5 = 4
If you want to do it the wrong way, you can
for($i = 1; $i < 5 ++$i){
$varname = "func" . $i;
$$varname = $i;
}
Personally I reckon you should do it the right way as Jim outlines.

Head to www.php.net and hit the downloads section.
unArchive the source, and type ./configure --help to get a list of the
compilabel extensions. Once you're done, you can ./configure
--with-this --without-that --enable this-thing --disable-that-thing
The compile instructions(a file called INSTALL AFAIR) and the PHP
manual are among the best docs I've ever seen.

Is php4-session installed??
I am running SuSE 9.1 and sessions work fine for me.

I'm open to correction but I think that normal output will still
appear. It's only headers like Content-type, or Location, etc that the

I'm not sure why you sent this to me(and me only). It's not me, but

I just plain suck at regex, so I was hoping to get some hints from you
regex experts out there. I'm sure it's been done a thousand times, but
I can't seem to find what I'm looking for with a simple google search:
$phone could be "1234567890" OR
$phone could be "123-456-7890" OR
$phone could be "(123) 456 7890 OR
$phone could have other unexpected characters in it, even control
characters.
So what I'm desiring to do is run some type of regex on $phone and only
return the integers and assign the cleaned string back to $phone. I
thought I knew how to do this, but it's not working.
Thanks for your guidance.

Hi, i need to sort data using ksort. Its complex data out from a
database (and no i can't sort it using the database sadly). I can change
my code to reflect a new way of sorting but only to some extent, im limited.
Now from the data i build an array of the things i need to display,
using the names of the hockey players i create a list that is supposed
to be sorted, look at the result, you'll see that accents are not sorted
althought my var_dump(setlocale(...)) returns that the french locale
(string(5) "fr_CA") has been chosen. Is there anything wrong? can i
change my code to fix this problem and how, cause all my tries point to
nothing.
(Btw i tried all the installed locales to no avail.)

Hi,
Thanks to everyone's help, that multipage monster of a form is now
working properly (yay!).
One problem I have though is that I stick the answers as each page is
completed into a table. If the user hits the back button, rather than
adding a new row to the table I'd rather update it if it's there. That's
fairly straightforward when it's 1:1 questions to answers:
$q_a_sql='INSERT INTO $userAnswerTable
( q_id, a_id )
VALUES ' . (implode(",",$qanda))
. ' on duplicate key UPDATE a_id = VALUES(a_id);';
But when it's 1:n, such as with checkboxes, this neat little plan of
mine is thwarted.
So if I change the userAnswerTable to three columns, u_id, q_id and
a_id, is there a way I can do all the 1:1 and 1:n in the manner I wish?
TIA,
JJ

Good Morning,
I was having a discussion with a fellow PHP Developer this morning and he
mentioned that he put's an '' sign in front of all function calls, and
every time he accesses an array;
I know that this is sloppy, and dangerous, but I don't know exactly what
this exposes him to, can any one give me any real world examples of why
this is bad, so I can relate it to his code?
php.net does not have much information about this. It seems like
suppressing errors, rather then catching them is problematic.
Thanks Again.
Justin.
attached mail follows:
Hello Justin,
I would guess that this is mostly performance and memory related. When,
for instance, trying to iterate an array, or a directory with files,
using on all function calls, it will attempt to go through the array,
attempting to allocate memory for each item, but when finding it
empty/broken, it leaves the loop and goes on to the next statement in
the code.
From what I can tell, PHP handles memory efficiently, although I
wouldn't hazard this when deploying a larger site using this type of
approach. Especially if the code inside a larger if..else block was
performed on an object that was created with function() call, and then
all the consecutive calls to functions operating on that object also
used . This would take up both CPU time and memory, possibly creating
leaks, based on how efficiently PHP would handle the operations on a
non-existant object.
A rule of thumb is to instead use empty() and is_array() and such
functions to discern if the object you are going to handle indeed is of
the type you wish it to be, that saves you both time and effort when
trying to debug something in the future. The empty() function goes a
long way here, unless dealing with integers, since empty() will return
true if the value is 0, which might not be desireable.
I hope this helps you in your argument against your fellow developer. :]
Regards,
Torgny

Any chance of revealing his identity - so that I can make sure that I
don't sub-contract him any work.

It's bad in that your system normally gives you an error when you do
something wrong. Sometimes your code can recover from errors, but your
code runs better if the errors aren't there.
In production code, you don't want the errors to show up on screen,
mainly because you don't want to expose the code you are using on your
back end. You fix this by modding the correct parameter in php.ini (
display_errors IIRC )

PHP displays errors for a reason. It is both egotistic, and foolish to
assume that your code will always be perfect. Errors enlighten you
when your code is not perfect, and give you the opportunity to perfect
it.
You can achieve a similar effect by setting display_errors to the
correct setting.

This is a Bad Idea. A Very Bad Idea actually. If he's just looking to
hide error output, he should at least edit php.ini
to log to an error file. Otherwise, debugging his code would be
horrible. The "" is total slop.

I'm going to partially disagree with some of the responses you get on
this by saying that it doesn't have to be sloppy or a bad idea. I use
the '' symbol on _some_ of my function calls (mainly MySQL stuff), but
only because I have my own error handling system in place. Some will
say that if you want to control what is being printed to the screen,
modify the php.ini file, but I don't fully subscribe to that. In
production, I do turn off notices, but that's about it. For me, it
boils down to my wanting to control the verbatim of the error; ie make
the error messages a bit more end user friendly. The reason I don't
like suppressing this in the ini file is it becomes a pain in the ass to
try and debug a customer's problem (with the customer on the phone), if
no error messages are showing on the screen for him/her.

Please reply to the list.
I don't know if it still logs the error (assuming you have error logging
turned on).

Example:
I was working on a HORRIBLE piece of code for a cart app. The original
programmer had a line like this:
$result = mysql_query( "SELECT * FROM user_logins WHERE
cookie='".$cookie."'" );
Where $cookie is a session id stored in a cookie (what else? ;). The
problem was, he had some faulty code that was not always properly
setting the cookie. So then he went and did the following:
$customer_id=mysql_result($result,0,"id");
Problem is, $cookie='' but there are no entries in the user_logins table
where cookie=''. So, the query is empty and trying to pull the customer
ID gave the nice little warning because E_ALL was on:
*Warning*: mysql_result(): Unable to jump to row 0 on MySQL result index
3 in *cart.php* on line *26*
So customers get confused because of the warning and on top of that they
have no items in their cart because customer_id is used to look up temp
carts (and it wasn't set). He couldn't figure out why it was happening
and he didn't have logging turned on, so all he had was Billy Bob saying
"My cart is gone. There was an error. I don't know what it was. I
didn't write it down." So then he decided to put an in front of the
offending lines. Customers no longer get an error. Excellent.
But wait! Three months down the road, we have the problem of the
vanishing carts. So third-party programmer comes in, turns on logging
so I can see the stupid errors and figure out what's going on, but
errors have been repressed! This is not helpful to anyone, I then have
to go through and figure out whether it will break something by removing
those stupid 's (there were a LOT of them).
The problem wasn't that he was using , but that he was not properly
checking for errors, and used to suppress bugs he couldn't duplicate
or couldn't figure out how to fix. In short, if you don't want the
customer to see the error, turn of reporting and turn on logging.
Anyone trying to debug your code three years later will thank you.

It will ignore it totally, it doesn't even make it as far as the log
files - which is why in most cases it's a bad thing to use. When it
comes to the mysql/i functions however I will suppress the error and
use my own error checking to avoid blank pages / unsightly warnings.

in short what you monkey is doing sucks - if it was a good idea php
would be designed to output or log no errors at all... ever ... funnily
enough that's not they way it's designed.
knowing how to handle errors properly AND doing it is IMHO one of the
main differentiators between amateur and professional programmers -
of course the true wizards among us know when they can break the rules
(e.g. hack up some nasty little script that scratches an itch knowing
full well it 'breaks the rules') :-)
if I were you I would give serious weight to the words of John Nichel
on this matter - he might not admit it but he really knows where his towel

I have two tables with orders of different type of articles.
order_table_1

2 | 54549 | 2005-07-31 6:56:28
I have to grab orders from both tables (last 24 hour), put them together
and then sort them by datetime ordered. Like this:
2 | 97001 | 2005-07-29 4:45:41
1 | 56982 | 2005-07-29 9:12:34

1 | 67452 | 2005-07-31 10:56:11
My idea was to grab first all orders from first table as
multi-dimensional array
$orders = array(
array('order_table' => 1, 'order_trans_no'
=> 56982, 'order_date' => 2005-07-29 9:12:34),
array('order_table' => 1, 'order_trans_no'

array('order_table' => 1, 'order_trans_no'
=> 67452, 'order_date' => 2005-07-31 10:56:11)
array('order_table' => 2, 'order_trans_no'
=> 36928, 'order_date' => 2005-07-29 11:12:54),
array('order_table' => 2, 'order_trans_no'

array('order_table' => 2, 'order_trans_no'
=> 54549, 'order_date' => 2005-07-31 6:56:28)
)
and then sort the array after order_date - but don't know how :(
I guess the best way would be to make a sql query and sort them while
grabbing them from db but don't know how to do it either :(
Any help?
Thanks!

If in php context you have class, say, A:
class A
{
var $t1;
var $t2;
var $t3;
//After, you have object contructor of type A
//we have something like this
function A ($var1, $var2, $var3)
{
$this -> t1 = $var1;
$this -> t2 = $var2;
$this -> t3 = $var3;
}
....some other code
}
//than in some other class we have something like this:
class someOtherClass
{
$aConstructor = new A(1,2,3);
//values of t1, t2 and t3 are 1,2 and 3 now
}
Right? yes.
How you can you do something like this inside of "someOtherClass"
print ($aConstructor);
to finally have some nice output like
Value of t1 is 1;
Value of t2 is 2;
Value of T3 is 3;
or just:
1
2
3
Without creating functions like getValues()
function getValues()
{
print ($this -> t1);
print ($this -> t2);
print ($this -> t3);
}
and after explicit invoke function:
$aConstructor -> getValues();
So, what I want is
this: print ($aConstructor);
and not this:
$aContructor -> getValues();
Am I clear :-)

Someone told you you shouldn't not call array() - in other words you
should call array(). If I'm reading you correctly then the someone is
right. You should not use a variable without initialising it, unless
it comes from a form, in which case you should not use it without
"cleaning" it.

I've been fiddling and found a typo in the config.php's UserFilesPath.
This now allows me to upload files (to the expected directory) but I
still cannot view the files in this directory in the file browser.

I have Textpad set up with syntax highlighting and I've added an
item to the 'tools' menu that allows me to perform a 'php -l' on the current
file (1 item for php5, and 1 for php4) - but the best integrated syntax checking
(and code analysis) I have found is in the Zend Studio v4 (aka ZDE) - really
a superb tool (although I feel some work could still be done on the general/non-php-specifc
editor functionality to bring up to par with some of the longer-standing/more traditional
editors that I have used)

ok - I would recommend cut-n-paste for this kind of output
to prevent idiots like me pointing out you typos and to avoid confusion
in general.
the next questions would be:
a, how many parents does the problem class (Link or Links?) have?
b, is Rank the base class?
c, does Rank::__construct() actually exist?
d, does the error also occur with php5.0.x? (as apposed to php5.1beta)

$param = array('rewardSchemeId'=> $tnt_rewardSchemeId,
'accountNumber' => $acountNumber,
'amount' => $amountIgnoringDecimalPoint) );
$result = $soap->call('recordBooking', $param);
[/code]
The problem is, I have not been able to convert PHP's integer/float type
to long because there is no function that does it. Or is there?
I've tried using settype() and (type) casting, but to no avail. I've
read a user's contribution note in PHP Manual for settype(), and he said:
"It's worth noting that one can neither <I>settype()</i> nor type-cast a
variable as a long. The workaround for this seems to be to use
<I>pack()</i>."
I've looked at pack() function and tried it but I don't think I'm
getting it right because the instruction is not clear to me ( I don't
have programming background). I've done the following:
$amount = pack('L', $amount);
Please assist. Thanks.
