The reason why is because there's no real long support in PHP.
But, since you mention a value such as 0.01, you are not looking for a
long, you are looking for a float. So, what you need to do is to
type-cast all the values involved in the making of the variable that
holds the float value.
For instance:
$var = (float)$var1 / (float)$var2;
$query = sprintf('%.2f %s', (float)$var, $string);
I haven't found the exact points where PHP forgets it's a float, but
it's always good to make sure all mathematical operations are performed
on the value as a float by type-casting, otherwise it might lose
information.

[PHP] dl exploit
There was a posting on http://us3.php.net/dl dated July 18th regarding the dl exploit problem. Following the advice in the posting, my shared hosting service disabled dl on our hosting server. I can't load my custom PHP extension anymore. I am wondering if anyone knows about any active development effort to fix this problem. Please let me know. Thank you very much. P.S. Text of the posting on PHP documentation page for dl: WARNING: enable_dl/dl() * There is an exploit circulating currently which takes advantage of dl() to inject code into Apache which causes all requests to all virtual hosts to be redirected to a page of the attackers choice. All operators of shared web hosting servers with Apache and PHP should disable dl() by setting enable_dl to off otherwise your servers are vulnerable to this exploit. This exploit is generally known as flame.so (the object that is loaded into Apache) and flame.php (the php script that loads it). -- Anas Mughal
[PHP] Converting integer type to long
Hi All,
I'm facing a little problem here. I'm making a few query using SOAP
protocol (NuSOAP class), that involves sending out an amount (e.g.
0.01), which is accepted in type of [long] in its WSDL, for recording
purpose. Typical call:
[code]
$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 settype() nor type-cast a
variable as a long. The workaround for this seems to be to use
pack()."
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.

[PHP] Re: help with a bucle
Sorry clarification required to my previous answer...
I sort of answered you in a hurry, and I made another assumption that I
didn't define.
I wanted to clarify that I'm assuming the array is setup as follows
arr[day]=>report.
arr[1]=>45
arr[2]=>56
arr[4]=>78
etc...
$y = 31;
for($x=0; $x < $y; $x++)
{
echo "day ". ($x+1) ." - report " . ((isset($arr[$x+1]))?
$arr[$x+1]:"0") . ""; //$x+1 is required because you can never have
day 0

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.

Do you have a key defined for all three columns *together*?

So, three different answers for the same user & same question. The one

One problem I have though is that I stick the answers as each page is

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

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?

Re: [PHP] Error Suppression with '@'
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.

I have to grab orders from both tables (last 24 hour), put them
together and then sort them by datetime ordered. Like this:

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'

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

Re: [PHP] Java - toString() <-> php - ?
Rory Browne a écrit :

I think they may do what you want without using the toString method,
which for what you're describing is basicly an ugly hack.
One more thing: Enlighten me: What exactly do you mean by "live
evolution" in your php/java context.
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 :-)

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.net does not have much information about this. It seems like > suppressing errors, rather then catching them is problematic. 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. > > > Thanks Again. > > Justin. > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Error Suppression with '@'
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 Justin Burger wrote: >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.

[PHP] Forming an SQL query
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

[PHP] Sorting in PHP
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.)

Re: [PHP] varibles defination
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.

[PHP] XSL custom xmlns/urn in PHP5 for callbacks
Hello, I recently started working with PHP5 after having spent quite some time with C#.NET (at work), and I was wondering if there's a way to create a custom callback namespace for XSL in PHP5? The example below should illustrate what I need: http://www.w3.org/1999/XSL/Transform"; xmlns:myapp.library="urn:myapp.library" exclude-result-prefixes="myapp.library"> Hope someone can help here. If not possible, I can always use the standard PHP function/class::method callbacks, but it would be nice to have custom xmlns so that I could add several different libraries.

You don't escape hyphens like that in a character class. Put it at the
end of the list of characters like this:
[a-zA-Z0-9'-]
Then it'll match your test address.
If you're trying to find out why a regexp isn't working, try
simplifying your test cases until it works. For example:
$email = "[EMAIL PROTECTED]"; // doesn't work
$email = "[EMAIL PROTECTED]"; // doesn't work
$email = "[EMAIL PROTECTED]"; // doesn't work
$email = "[EMAIL PROTECTED]"; // works!
I don't suppose this is the place for a rant about the futility of
checking email addresses with a regexp?

Even more basic, no php required (but not suitable for internet use as it
relies on your browser knowing what to do with a mailto link:
Dropdown Value to Email
mailto:[EMAIL PROTECTED]>
Purchase
Construct Home

Re: [PHP] Java - toString() <-> php - ?
Adi Zebic wrote:
To print "state" of object in Java I can define toString() function and
then I can do something like this:
Java exemple:
*
import java.io.*;
import java.util.*;
public class ReadTextFromFile
{
private static String line;
private static String Fable = new String ("");
private static String NomFable;
private static int cptLine = 0;
private static int nbrPersonnes = 0;
private static String nomPersonnes = new String ("");
private static ArrayList AListe = new ArrayList(nbrPersonnes);
//**
public String toString()
{
return getClass().getName()
+ " [ Nom de la fable: "+ NomFable
+ " <==> Nombre de personnes dans dialogue: " + nbrPersonnes
+ " ] "
;
}
***
Is there similar kind of function in php that help us to print the state
of object in his "life evolution"?
there is but it's use is limited and currently AFAIR it only works on
internally defined
classes the method is called __toString() - from what I have read and
played with it (not
recently though) the fucntionality is _bit_ 'halfbaked' - as in the internals
guys are still
pondering how to imnplement this as nicely as possible.
an example:
the problem with implementing this is the fact that php is dynamically typed -
and it
autocasts types all over the place - very handy BUT it makes a __toString()
[magic] method
very hard to implement in a way that is obvious to the people using it (try
playing around with
the SimpleXML extension to see how it can warp your brain! well it makes my
head spin anyway :-)
but don't take my word for it - try it yourself, oh and also take a dive into
the [php]internals mailing
list archives - lots has been discussed about this function AFAIR.
Thanks

[PHP] Re: Sessions Issue
did you check the output of "phpinfo()"? if you did not made modifications or manual configurations, the session support should be on in defalt. ~viraj.

If that's your first use of $data then it's not necessary, but it's very
highly recommended to do something like:
DITTO! :-)
$data = array();
the someone who told you don't is wrong - by setting $data to an array()
explicitly just before you use it you we be sure $data contains exactly what
yuou think
it should when your while loop (in this case) completes...
imagine you came back to a script containing this code and you added a similiar
query loop above also using the var $data!
don't worry about the difference in performance (whether you initialize the var
to
an array() or not) - you can't even measure it in any valid way.
mysql_query("SELECT ");
while($rows .)
{
$data[] = $rows;
}
you might even consider that it is not always worth looping just to create
a $data array - often you can process/output/whatever each $row as you
encounter it...
imagine what happens if your query returns a million records, your script could
process
each $row 1 by 1 (granted it would take quite a while!) but trying to fill a
$data array
would almost definitely cause your script to die due to memory exhaustion.
(either a php limit
or a system limit)
That way you _know_ that $data is "clean" before you start doing
anything with it.
It's always a good idea to set any variables you're using to some value,
either "", array(), 0, or some default value, before you use them to
help keep the "bad guys" out of your scripts.
