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.

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;

Not to be a smart ass like Danial was (which was brilliantly written

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

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.

NAT is where you have an internal network using private addresses (often in the 192.168.xxx.xxx range) but all outgoing traffic appears on the internet to come from one public address. So you configure your web server to accept requests from only the internal addresses. With Apache you could do this on a per-directory basis, even, so the web server could have public content (visible to all client addresses) and then have private content in subdirectories which only accept clients on the internal network addresses.

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.

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.

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');
seems to be the right quoting - the filename needs to be in double-quotes

Two of those,?php ? andscript language=php /script, are always available. The other two are short tags and ASP style tags, and can be turned on and off from the php.ini configuration file. As such, while some people find short tags and ASP style tags convenient, they are less portable, and generally not recommended. But the implication there is that they are *only* non-portable *because* they can be switched off - there's no other strong reason. Before anyone jumps in with XML / XHTML arguments again, those issues are fairly rare and very easily worked around. My projects tend to use XHTML doctype because it makes IE7/8 behave more predictably without a ?xml ? block, and I always use short tags for ?= because the alternative is so ugly! In the rare cases where I generate XML from a PHP script, there are workarounds for the ? problem. I do tend to use ?php for blocks of code - so I guess I'm in the middle camp here.

[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.

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

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.
