[PHP] strcmp($var1, $var2) versus if ($var1 $var2)

Implicit type conversion. is a numeric operator, so your strings
are silently promoted to integers, where (1011090 10190).
strcmp() treats the strings as strings, and orders them in something
close to ASCII order (which isn't the same as alphabetical ordering,
BTW, and see the comments at www.php.net/strcmp for locale-specific
gotchas).
PHP's implicit conversions can bite you if you don't understand them.
Try this one:
$a = 'string';
$b = 0;
if ($a==true $b==false $a==$b)
{
echo ('universe broken');
}
Hi David,
I already suspected that the operator forced a numeric comparison.
Even if I use: if ((string) $var1 (string) $var2) ...
So I have to use strcmp()
Thanks, Cor

I know it does have its price. Regards, Cor Hi Jochem, Engine.php does the following: a. checking validity of form query fields b. sending messages if invalid form query fields c. building the sql and executing it d. new: building $_SESSION['data'] for Report.php e. include / redirect for different output formats Step d. now passes the result set to Report.php. So Engine.php now redirects to Report.php once per query, and when the user changes report settings, Report.php is called by itself with required settings. More or less comparable to http://www.tonymarston.net/sample/person_list.php, except that my application is read-only and provided with graphs. I have to admit that I haven't tested the time needed for steps a-c. So I may save some time at the cost of extra mem to pass SESSION['data']. On the other hand, by splitting Engine and Report code I may save some mem, I think. Thanks for your time, Jochem.

Re: [PHP] Transfer query result to another script
Hello David, Jim,
Thanks for your response.
Yes, I do have session_start() at the top of Report.php.
The reason for having the query on a different page than the result
is that the result may be sent to various output types / scripts.
I will change my code as follows:
Engine.php
-
$result = mysqli_query($connect, $myquery);
if (!$result) error ...
if (mysqli_num_rows($result) == 0) error ...
// fill $_SESSION['results'] with query result
switch ($output)
{
case HTML: header(Location: Report.php); break;
case CSV: ...
case XML: ...
case PDF: ...
}
Thanks again for your advice.

Cor,
Do you have session_start() at the top of Report.php?
The manual shows an example of passing a php created class object using a
session variable, with the caveat of needing to include the class definition on
each page.
It may be different for a mysql result object though.
Why do you need the query on a different page than the result?

WRONG!!!
there is no reason to do a redirect, use an include to run code
relevant to the selected $output (and you'll have the result set available
for no extra charge).
and you can't stick resources (e.g. a resultset id) into session
and expect them to persist - the value may be there, but the resource
it pointed to is loong gone by the time the second script starts.

Hi Jochem,
The reason for a redirect is that Report.php has functionality such as
sorting on report columns, checkboxes to make graphs etc.
Suppose the following report columns:
Country 06.Q1 06.Q2 06.Q3 06.Q4 07.Q1 07.Q2
1 Austria 1226 12111233132813861362
2 Belgium1004 11931008973711021270
3 etc.
If I don't use a redirect but an include Report.php then Engine.php must be
rerun:
- every time a user wants to sort on a columns, eg. Y06.Q1
- every time a user wants to make a graph with selected rows.
Right ? I did use an include but I'm changing it because of the reasons
above.

Re: [PHP] repetition of tedious references
Hi OLav,
what about this ?
$language = isused($_SERVER[HTTP_ACCEPT_LANGUAGE]);
echo language is . $language;
function isused($variable)
{ return isset($variable) $variable != ? $variable : *;
}

Subject: [PHP] repetition of tedious references
consider the following statement:
$language =
isset($_SERVER[HTTP_ACCEPT_LANGUAGE])
$_SERVER[HTTP_ACCEPT_LANGUAGE] != ?
$_SERVER[HTTP_ACCEPT_LANGUAGE] : *;
when using strings in arrays that may be non-existing or empty, you
have to repeat the reference *three* times, which gets excessive and
unreadable.
is there any way to only have to write
$_SERVER[HTTP_ACCEPT_LANGUAGE] only once?
i know it's possible to supress is not set with @, but that just
seems wrong in case there really is an error in the statement.
i love php, but this is one of my pet peeves.

[PHP] Dynamic refresh dropdown list
I have a selection form with multiple dropdown lists, let's say A, B and C.
If the dropdown list B is changed, then dropdown list C should be updated.
To get this done, I use a small javascript
function reload(form)
{ var val=form.B.options[form.B.options.selectedIndex].value;
self.location='myForm.php?B=' + val ;
}
called by
select id=B name=B onChange=reload(this.form);
This works fine, BUT all other dropdown lists are also reset.
So if I select another A, then another B, then also A is reset to its prior
value.
Any idea how I can refresh a specific dropdown,
without affecting all the other dropdowns ?
TIA, Cor

Remember that the http protocol is stateless. Every request made is a new
connection to the server. It's due to extra technologies like cookies (and
in this case sessions) that some form of 'state' can be maintained.
However, because there is no communication between client and server
unless the client makes a request you can never actually determine the
_current_ status of your session, only in retrospect you can. If a user
makes a request, you could say the session is 'in progress', however,
after sending that page you don't know if it's still 'in progress' or has
ended until you recieve another request, thus telling you it WAS still in
progress.
Now, as for resources and connections: PHP clears up everything when it
finishes sending a response to a request. This does not happen for certain
very specific items which were stored away (like in a database or in a
session, which is usually just a file). For a connection to be 'open' it
needs to be able to communicate with both its' sides (client: your
database; and the 'server': PHP), if php 'shuts down' because it finished
the request, it doesn't leave anything of itself behind, and as such the
'server' of that connection also disappears, thus creating a broken link
which is automatically destroyed. Of course the php engine is smart and
knows this would happen, so it 'cleanly' closes the connection before
disappearing to reappear again (fresh) on a next request.
hope that helps you understand,
- Tul

Of course, that doesn't necessarily stop ? passthru('uname -a').\n; ?

If it's suggesting that it's an array, that's a little baffling, because
that means there are multiple entries (at least two), but they appear to either
be null or otherwise unable to display.
Did you get that result when running the script from the CLI or via the

Re: [PHP] getting $_ENV variables
Yes, my PHPinfo shows under configuration: variables_order = GPCS I will test EGPCS setting in php.ini But that also means that code using $_ENV cannot be run with hosts hiding the environment settings ?!

The $_ENV superb-global contains an array of environment settings, so it's not totally baffling that print_r() on it should return an array. The reason it is empty is because the variables_order setting in the php.ini has had it disabled. The default is: variables_order = EGPCS But it must have been changed to: variables_order = GPCS Dropping the E (Environment variables) will cause a print_r($_ENV) to be totally empty. Some hosts do this in order to hide the environment settings because they can contain sensitive information such as the CPU identifiers, etc. I've seen the 'cheaper' hosts (especially those hosting on Windows and/or Virtual Servers) disable this so you can't tell what kind of CPU they're using, or where their system drive is.

No, $_FILES isn't part of the Environment list, it's created again at run-time when a file upload occurs.

[PHP] scrolling HTML tables
I hope it's not the wrong place to ask, but has anyone experience with scrolling HTML tables ? According http://www.w3schools.com/tags/tag_thead.asp The thead, tfoot and tbody elements enable you to group rows in a table. When you create a table, you might want to have a header row, some rows with data, and a row with totals at bottom. This division enables browsers to support scrolling of table bodies independently of the table header and footer. I don't want to reinvent the wheel in own software. Or is it better to ignore these tags because of bad browser support ? Thanks, Cor
