Guess which one the big commercial organistations (banks, industry etc.) prefer to trust? Guess which is then popular for college courses since it provides the students with a basis in something that is commercially desirable? From my personal point of view, I started with BASIC, then FORTRAN (in a scientific environment), then C/C++, then Java (which I saw as the language C++ should have been), and then moved on to PHP in a search to find a way of building web apps in the sort of timescales that small-medium enterprises are prepared to accept.

Hi all,
I want to start a discussion about a PHP behaviour that drives me crazy for
years. For the beginning I would like you to guess what the result of the
following snippet will be:
var_dump('PHP' == 0);
I know the difference of == and === but the result was unexcpected for me. And I hope it
is also for you. The result is simply true. Why is it true? I guess this
happens because of the conversion from 'PHP' to a number which will be 0 in PHP. And of
course 0 equals 0. There are several points that I just want to drop into this
mailinglist to discuss about:
1. Why? :)
42
2. Why is PHP converting the String into a Number instead of converting the
Number into a String? (If my guess concerning the behaviour is correct)
Since PHP is a weakly-typed language, it has to choose one way or the
other. The behaviour *is* predictable if you know what the rule is (I'm
sure the order of conversion is documented somewhere).
3. Why is PHP throwing data away which has the developer explicit given to the
interpreter?
Because PHP is weakly-typed, the developer is not being sufficiently
explicit. Try
php -r 'var_dump(intval('PHP') == 0);'
and
php -r 'var_dump('PHP' == strval(0));'
to see explicit code. Anything less is implicit.
4. Why does var_dump(0 == 'PHP'); has the same result as the snippet above?
This meens that the equal operator is not explictly implemented in the string
or integer?
The rule is consistent: it always converts the string to an integer
whatever the order.
5. Thats a bug I have opend: https://bugs.php.net/bug.php?id=51739 where I also had the same
problems because 8315e839da08e2a7afe6dd12ec58245d was converted into float(INF) by
throwing everything starting from da08.. away.
That's a very different proposition, and probably has more to do with
word size: float is 32-bit, so only the first 32 bits are used and if
anything else is found the conversion falls back to INF. To handle
really big integers like 8315e839da08e2a7afe6dd12ec58245d you probably
need a more specialist library (or language)
I am using PHP since the year 2000. This means I have 13 years of experience in PHP and I really
would like you to NOT just answer works as designed. I know it works as designed but I
want to discuss the design. Also I know that the fuzzy behaviour of type conversion is
a main feature of PHP. I guess this is one point which makes PHP that successfull. But - in my
opinion - the described behaviour is to fuzzy and just confuses developers.
The weak typing *is* a feature of PHP: other languages are more suitable
when you need more enforcement of types: Java, for example.
With all due respect to an experience programmer, years of experience do
not make up for a limited tool set.

For me it is not. PHP throws things away during conversion. In my opinion a
language (compiler, interpreter whatever) should not do that. Never ever!
Either it is able to convert the value or it is not.
What about of returning null instead of 0 if the conversion is not perfect?
So intval('F') could return NULL and intval('0') could return 0.

Daniel
I've had a bit of a play with your big hex number, and the problem is
much more subtle: floatval(8315e839da08e2a7afe6dd12ec58245d) is
truncated at 8315e839 because it tries to parse it as an exponential
float: floatval(8315e83) becomes 8.315 x 10^86, but 8.315e839 is 8.315
x 10^842 which is (as far as PHP is concerned) an infinitely large number!
So we try replacing that first 'e' with a 'd' (for example) and then
php -r 'var_dump(floatval(8315d839da08e2a7afe6dd12ec58245d));'
returns
float(8315)
It gives up when it finds a non-numeric character (as the documentation
would tell you)
Perhaps what you need is
php -r 'var_dump(floatval(0x8315e839da08e2a7afe6dd12ec58245d));'
float(1.7424261578436E+38)
In other words, you need to tell the interpreter that you have a number
(in base-16) rather than a string.
A proper strongly-typed language would just tell you that it's nonsense...

[PHP] PHP download page blocking other HTTP requests
I have a file download 'guardian' page which does something like this:
$size = filesize($path);
$fi = @finfo_file($path, FILEINFO_MIME_TYPE);
@header('Content-type: ' . $fi);
@header('Content-Length: ' . $size);
@readfile($path);
exit;
($path is derived from parameters in the request, including checks for nasties
and some access control checks in the system)
When a link is clicked which points to this script, the file is downloaded (well
and good...), but in Firefox (3.x, 4.x at least), it seems to block any further
interaction with the browser until the download is complete - some of the files
are 60Gb and the server is on a 2mbit line, so it can take some time to download.
Is there something on the Apache/PHP end that might be causing this blocking?
(Apache 2.2.10, PHP 5.2.14)
I suspect not, since using Chrome as the browser doesn't appear to have the same
problem, but I wondered whether there was some way that FF was handling the
headers might be causing it.
I can't seem to devise a suitable Google search to get any mention of similar
behaviour so I thought I'd ask some experts :)

The Incognito feature wont give you the results you're looking for.
From my experience, the incognito window(s) and tab(s) share the same
memory/cookie/session space, which is different from the main window...
which means you will run into the same issue.
Once you close all your incognito windows/tabs, you will release those
cookies/sessions/memory space and if you open a new one afterwards, then
you will be fine, but if one tabs stays open, no go :(
Have you looked at the http://ca3.php.net/session_name function, and
putting that into your site just after your session_start() ? I believe
that will fix your issues (as long as your session names are unique),
but i am not 100% sure.
Steve
Thank you for this suggestion. This has solved the more serious half of my
problems; I can
easily generate a different session name for each website, so that the various
websites
don't interfere with each other, but I have not been able to devise a way to
differentiate
between multiple sessions of the same website.
For example, if I open one copy of a website as a visitor I am shown as
Visitor, but if I
then open another window, and log in as Manager, then go back to the first
window I am
shown as Manager (with appropriate privileges) there also.
The only way I can think of to overcome this would be to generate a new named
session
every time I log in, and then to pass the session name as a parameter every
time I load a
new page. Unfortunately my program is sufficiently complicated that this is
effectively
impractical, as it would involve tracking down and modifying every point in the
program at
which a new page can be launched.
It also has a theoretical disadvantage that if someone bookmarks a page they
will book
mark the session name, but this can fairly readily be overcome.
Is there any alternative way in which a different session name (or equivalent
flag) can be
attached to each instance of the browser?
(Effectively these problems only affect the developer, as they only apply to
multiple
instances of the same browser on the same PC.)
PS. At this stage I devised a really nasty kludge, which enables me to run
multiple copies
without them interfering. In my program new pages are always launched by a
command of the
general type:
http://localhost/cypalda.com/index.php?level=1item=22
This loads the file index.php, which is a very brief file in the public
directory
(cypalda.com in this case). It sets a couple of constants and then transfers
control to a
file Begin.php, in a private directory. This in turn sets up a whole lot more
constants,
and then transfers control to the main program, which is common to 5 different
websites.
I realised that if I specify the session name in index.php, I can make several
copies of
this file, e.g. index.php, index1.php, index2.php, each of which specified a
different
session name. I thought this still left me the problem of modifying all the
points at
which a new page was launched, but then I found that by great good fortune (or
foresight!)
I had defined a constant $home_page = index.php, and always launched a new page
with the
basic command
echo ('a href='.$home_page.'?ident=' ...');
So all I had to do to achieve the desired outcome was to specify a different
$homepage in
each copy of index.php. Then, once I had launched a particular copy of
index.php, that
instance of the browser would always load the session appropriate to that copy.
Even better, if I upload the various versions of index.php, I can run multiple
copies of
the public website on the same PC without them interfering.

Many thanks. Unfortunately, as I mentioned in my OP, the DateTime
class seems to be 'broken' for my purposes because it uses strtotime()
to convert input strings to date/time. Rather than fail when presented
with an invalid date, strtotime() returns the 'best fit' if possible.
This can be seen from:
$date = new DateTime('30 Feb 1999');
echo $date-format('Y-m-d');
which results in 1999-03-02 even though 30 Feb is an invalid date.
If you could programmatically determine the format of the input, you could parse
the date using DateTime and then rewrite it using the same format as the input,
and compare those.
Now that starts to work if you can *control* the format of the input, or at
least limit it to some familiar options.
So maybe:
$userInput = '30 Feb 1999';
$dateTest = new DateTime($userInput);
if ($userInput===$dateTest-format('Y-m-d') ||
$userInput===$dateTest-format('d M Y'))
{
echo 'Date is valid';
}
else
{
echo 'Not valid';
}
It starts to get logn-winded after a while, and doesn't rule out ambiguous
cases...
Or split the date input into pieces in the form (if possible) and then you can
validate the date how you like
$userInput = $_POST['year'].'-'.$_POST['month'].'-'.$_POST['day'];
$dateTest = new DateTime($userInput);
if ($userInput===$dateTest-format('Y-m-d'))
{
echo 'Date is valid';
}
else
{
echo 'Not valid';
}
Finally, for some applications I have made an AJAX (javascript + PHP)
implementation which provides feedback to the user as they type in the date
field: every time a character is typed in the box, the backend is asked to parse
it and then format it in an unambiguous way and send it back to the client. That
way the user can *see* if what they are typing is valid...
Of course, you *still* have to validate it when it's posted (and the network
overhead might be too much).

twice. Now I'm not to sure, but it is possible that looping over
mysql_fetch_array($result) moves an array pointer so the count is not
valid after the operation... that's a long shot.
But since you are looping over the database records anyway, why not just
count them as you go? Isn't $i the number of counties after all the
looping?

$result = mysql_query(SELECT * FROM `counties` WHERE name = 'checked')
$county_total = 0;
while($row = mysql_fetch_array($result))
{
echo $row['name'];
$county_total++;
}
echo $county_total;

Thank you for your suggestion...btw cut out the decoration LOL
I'm sorry to report it did not work. I tried various configurations of it
but to no avail.
Any other suggestions?
Again, thank you for your help.

Gary,
I'd probably need a bit more detail on the it did not work to go much further!
Actually, it looks like I missed a semicolon on the mysql_query line in *both*
versions - maybe that was the problem...
Do you have access to your server logs, to see if any errors are reported when
you run this?
Cheers
Peter

You loop over $_POST['counties'] and look for $_POST[county$i]
I suspect that there is no field 'counties' in your form, so the server is
complaining about the missing index - seems likely that the production server
is not showing the error, but instead just giving up on the page.
I think the IE7/Firefox browser difference is a red herring: it wasn't actually
working in any browser, or the code changed between tests. Remember, PHP is
server side and generates HTML (or whatever). Unless you tell the PHP what
browser you are using and write PHP code to take account of that (not generally
recommended) then the server output is the same regardless of browser.

The first thing I see is that you do

twice. Now I'm not to sure, but it is possible that looping over
mysql_fetch_array($result) moves an array pointer so the count is not valid
after the operation... that's a long shot.
But since you are looping over the database records anyway, why not just count
them as you go? Isn't $i the number of counties after all the looping?

Thank you for your reply.
I did notice that I had the $county_total=mysql_num_rows($result) twice. I
had moved and removed it, always getting either a 0 or 1 result.
I put up another test page with
$result = mysql_query(SELECT * FROM `counties` ) or die(mysql_error());
$tot=mysql_num_rows($result);
echo $tot;
?
And it worked fine.
I have tried count() as well as mysql_num_rows() but am getting the same
result.
Could you explain what you mean by count them as I go?
Again, Thank you for your reply.

Well,
Lets go back to your original code and cut out the decoration:
$result = mysql_query(SELECT * FROM `counties` WHERE name = 'checked')
$county_total=mysql_num_rows($result);
while($row = mysql_fetch_array($result))
{
echo $row['name'];
}
echo $county_total;
That code should do pretty much what you want...
But, because you only show the number of records AFTER the loop, you could do:
$result = mysql_query(SELECT * FROM `counties` WHERE name = 'checked')
$county_total = 0;
while($row = mysql_fetch_array($result))
{
echo $row['name'];
$county_total++;
}
echo $county_total;

Steve,
The commas are not concatenation. They are separators for the echo construct.
I don't know the internals well enough, but ...
echo $a.$b.$c;
vs
echo $a, $b, $c;
On the surface, the first instance has to create a temporary variable
holding the results of the concatenation before passing it to the echo
construct.
In the second one, the string representations of each variable are
added to the output buffer in order with no need to create a temp var
first.
So, I think for large strings, using commas should be more efficient.
Richard.
Well... I have been learned. I had no idea about doing it that way, I
apologize to you, Jim.
I guess my PHP-fu is not as strong as I had thought?
Thank you Richard for pointing out this to me, I may end up using this
method from now on. I have just always concatenated everything as a
force of habit.

There's no reason why HTML with single-quoted attributes isn't valid, so in

The real challenge is to understand why the code fragment you have presented is

The Daniels are on the right track, but not very clear:
First, the input elements all have the 'name' attribute set to 'email' and the
'class' set to 'referral_1' etc. - I think you have that the wrong way round!
Second, using single quotes in the $_POST['referral_$i'] bit will not work (DPB
is right there) - use $_POST['referral_'.$i] or $_POST[referral_$i]

If you needed the double-quotes in the Xpath expression when the constant is
used , then you probably need them in the variable version.
$v = $row-xpath('//membernumber[. = '.$MemberId.']');
That should put the double-quotes in for you...

Am I not understanding what you are trying to ask?
I tried this but doesn't work. I guess the above statement is
concatenating the entire string and the substitution isn't happening
What I am trying to do is as follows
$MemberId = 'A192';
$v = $row-xpath('//membernumber[. = ' . $MemberId . ']');
The $MemberId should be substituted with A192 and then the xpath query
should be executed. The result should be that I locate the membernumber
XML element that has the value A912.

So you can't stop people from uploading anything to your site via the form, but you can look at the document once it's there and inspect it. Using a HEX Editor, I see that most pdf file have the first four bytes as %PDF so you might check that before moving the file to somewhere important. But that doesn't stop spoofing.

I also run every upload through a virus scanner (clamscan, for example) before I accept it. If your PHP backend is windows then you might need to do some research to find a good file-type detection routine, although the virus scanning should be possible. You certainly cannot trust the client side to do any checking. In any case, JavaScript doesn't (shouldn't) have access to the file you are trying to upload, so there's not much you can do there. You might achieve something client-side with Flash, or a Java uploader applet, I suppose.

Are you sure that you need Content-Disposition? Try removing that. I
think that's used only in emails (Correct me if I'm wrong).
You're wrong. Content-Disposition tells the browser how to handle the
content - in this case, the browser will download the file instead of
displaying it.

I think you need to be careful about quoting the file name in the
Content-Disposition header: something like
header('Content-Disposition: attachment; filename='.$filename.'.xml');

[PHP] Re: Enforce a constant in a class.
Richard Quadling wrote:
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.

Richard.

[PHP] php/ruby drb adapter
Hi, I'll be honest: php is not my favorite programming language. That honor goes to ruby. And I don't mean ruby-on-rails; just straight, pure unfettered ruby. I use ruby to write web applications and just about everything else. However, there are obviously very many web applications and webapp frameworks written in php. I have recently taken an interest in eyeOS (http://eyeos.org/), with the intent to hack eyeOS to use a certain ruby back-end file service I've written instead of accessing the local file system directly. This ruby service communicates with clients via ruby's native distributed ruby (DRb) facility. DRb makes it marvelously easy to write distributed multi-threaded services, provided the clients are written in ruby as well. But what if the client is written in, say, php? Wouldn't it be nice if a php client could access DRb-driven ruby services just as simply as a ruby client can? Not finding any such existing facility, I've written a php object class, DRbClient. This class invokes object methods offered by the remote ruby service, passing strings, integers, floats, booleans, nulls, and/or arrays as arguments, and accepts a return value of any of those same types. All data translation and inter-process communication is transparent. It's just as if a local object instance is being messaged directly. If there's interest, I'd like to offer DRbClient to the php community, but I'm not sure how to go about that. -- Pete Yadlowsky ITC Unix Systems Support University of Virginia -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Use a JS calendar widget (requires js) or use three select boxes for mm , dd and year I developed my little text input AJAX (see earlier post) to work around the fact that a LOT of users I encountered were cheesed off by JS calendar widgets, especially when the date to be entered was a long way from the current date (such as a date of birth). I tried implementing some scroll-wheel events to speed up year selection on one of these but it was tricky to get cross-browser support. Drop-downs are a pain when you have to scroll back 40+ years to find the right one and are implicitly limited by how far back and forward the designer expects to need, and then you have the problem of validating the days and months (which, to be fair, is a pretty simple javascript task) I suspect that with a bit of thought I could put together a Javascript date validator that parsed most possible inputs and produced a sensible interpretation of them, but I was lazy and had AJAX machinery set up already in my project. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: strtotime - assumptions about default formatting of dates
On 24/12/09 12:20, Angus Mann wrote: Hi all. I need to allow users to enter dates and times, and for a while now I've been forcing them to use javascript date/time pickers so I can be absolutely sure the formatting is correct. Some users are requesting to be able to type the entries themselves so I've decided to allow this. I'm in Australia, and the standard formatting of dates here is DD/MM/ or DD-MM- I recognize this is different to what seems to happen in the US, where it is MM/DD/ or MM-DD- When I process an entered date using strtotime() it seems to work fine. But of course I am concerned when dates like January 2 come up. I find that 2/1/2009 is interpreted as January 2, 2009 on my installation, which is Windows 7 with location set to Australia. But can I be sure that all installations of PHP, perhaps in different countries and on different operating systems will interpret dates the same? I can't find much mention of this question online or in the manual. Any help much appreciated. Angus I wrote a little AJAX gadget which sent the string typed to a PHP backend which parsed it using strtotime and then formatting it out again as something unamiguous (like 2 January 2009). Then every time the date entry field is changed by the user (with an onKeyUp event), this AJAX call is triggered and displays the unambiguous form next to the input box, so users can see how their entry is being interpreted. Of course, there's some overhead in the AJAX calls, and it requires JavaScript. If you wanted to do without JavaScript you could do a similar parse-format sequence when the form is submitted and show a confirmation page with your server's interpretation of the date.

That's correct. Where I placed the $_POST['from_addr'] stuff,
just replace it with $_POST['field_4']. And then, of course, you can

[PHP] Devenix Live CD PHP4 and PHP5 project needs help
Hi, This seemed like the most sensible place to start to ask for help. I'm currently working on Devenix, a project based on the knoppix live cd. It will eventually be a complete php design and test studio on a live cd, carry around a memory stick and save everything onto it, basically enabling you to work on any computer anywhere and get straight back to work. My PROBLEM is this. I need to install php4 and php5, my reasons? I want to make it a studio capable of assisting with code migration and testing from 4 to 5. php4 is already installed via the debian apt source. I initially tried installing php5 by compiling from clean source, but only ran into problems. I am now working on modifying the php5 source tar from the apt-sources to install into a different dir to avoid conflict with php4. I added teh prefix line to the common configure line in the debian/rules file, but this screwed up the libapachemodule rebuild when i tried to rebuild the pacakge. Please any advice here would be greatly appreciated. And any people wishing to help on the project would be fantastic. There is no website yet, once this stumbling block is overcome, the ball will start rolling.

On most webservers you will need to name your 123 file not as 123.html but as 123.php or 123.phtml abc.html can continue to be abc.html Again I realize this is a complete newbie question but I appreciate any help you have. Todd A further point (since you are newbie G) is to remember that abc.html will not normally be a complete page on it's own - it will only have the parts of the final page that you actually want to include, not all the HEAD...

[PHP] Re: Unsetting vars when not needed?
Unsetting class objects does take time and is really of no benefit unless there are memory problems as for freeing resuslts - the same applies pete Jordi Canals wrote: Hi all, I was working now in a new site developed with PHP 5.0.2 and a wonder came to me: Is usefull and recommended to unset a class instance when not needed? Specially when the class was instantiated inside a function and the function ends. In this case, the system should automatically destroy the instance (as it is a local var inside a function). If we manually unset the instance at the end of the function, does this affect the PHP performance? I mean, will PHP have to do an extra job unsetting the var? Also, the same question arises with database results. Is it worth to call mysql_free_result at the end of a function that uses it? Must take into consideration that there are lots of functions that use lots of MySQL results.

You should only save the userId in the session, everything else should
be retrieved from your database using that id.
I normally do as you have suggested here - but why do you suggest that
this method is better?

I have just started using mod-rewrite, and have two questions... I see everywhere on the net that I can change file names to lower case - at present they are an ex-Windows based mess of upper and lower. But I can't see anywhere how to actually do it, just that it is possible. Also, I use RewriteRule ^comm/(.*).php /comm.php?C=$1 to change comm.php?C=abc to a more search engine friendly comm/abc.php. But this leaves gives the effect of being in a different folder, and relative URLS within that page no longer work correctly. Is there a Clever Fix? Or do I have to change to absolute URLS?

[PHP] Generating MySQL Tables
Is MySQL off topic for this list? If so, I apologise. I am supplied with various text (CSV, etc) data files, which I need to manually massage before I import into the main database. I feel that I can deal with them better by turning them into SQL tables first. I know about LOAD DATA INFILE, but this requires a table to exist, and I don't know the format of the table until I receive the text file. Is there any simple way of automatically creating a table and then importing the data? If not, I think that I will have to create a dummy table, with, say, 50 blob fields (some text fields are 'a paragraph full'), and work from there. Of course, it doesn't need to be fast to run. -- Pete Clark -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi Everyone,
I'm trying to build a class to handle various SQL functions.
One of them is to take a query, and return all rows. Here's what I have so
far:
function selectRows( $sql )
{
$count = 0;
$results = mysql_query( $sql, DB::connect() );
$data = mysql_fetch_array( $results );
return $data;
}
Right now it only returns 1 row. I'm guessing this is how it
should be, considering I haven't looped thru any other rows.
What I want to do is return something that holds all the rows,
however, I cannot see a decent way of doing this. I've played with putting
it into a new array, but I can't decide if that's the best way to do it.
Wondering if I could get some opinions on how you all would
handle this?

[PHP] Re: Best external app from php
I had a similar scenario recently the way I tackled the problem was to set a cron to trigger a cli script every minute the script first checked a database to see if there was any jobs queued then processed in the background works a treat pete C.F. Scheidecker Antunes wrote: Hello all, I need to have a web application to call an external app that needs to execute on the background. (It is an *NIX server) The app that is being called will do a lenghty work but will be called by a php script through the web server. An user will log in, request a computation, the script will call an external app which will run on the background. Once the job is completed, a notification will be sent to the user which will log in again and check the results. The external app performs a data mining computation on the SQL server to produce results which will then be written to an SQL table. My question is this: Is it better to write the external app in PHP or Java? If I write in PHP then I have to have a way to make the PHP not bound to time limitations as the operation might take a while. If I write it in Java I won't have this concern. However, I am concerned with speed and overhead. Which one would put a higher load to the processor, a PHP app or a Java one? Which one will take longer? Also, there might be more than 20 of these threads running on the server at the same time, hence my concern on which language the app should be writen. Does anyone has experience with such a scenario? The input is much apreciated.
