OK, so why does isAttendanceReport() return 0?
When debugging it's always a good idea to plugin absolute values where
possible, ie instead of using isAttendanceReport($SID), use
isAttendanceReport(1).
Isolate the problem, just run isAttendanceReport() on its own and plugin
various values to see what comes back.

You're not wrong, like I said it's _good practice_. Say you revise your code
to add more statements, it is all too easy to forget to put in the braces as
well thus resulting in faulty logic in your code and you pulling your hair
out trying to figure what the problem is. PHP's flexibility also means that
there is more than one way to shoot yourself in the foot (TIMTOWTSYITF (TM)).
BTW PHP is not an oppressive language at all :)

When using 1 in the fuction... no change....
During the code... it gets to the following point...
[snip]
#############################################
# Check if report report is present or not #
#############################################
if(!mysql_num_rows($dba['results']['attendance_report'])){
#report is not present
return 0;
}
else {
#report is present
return 1;
#gets here
}
[/snip]
it gets to the return 1 section....
however the calling statement just does not seem to work....
using SID = 1, mysql_num_rows($dba['results']['attendance_report'])
evaluates to 8
Dunno if that helps....
> Isolate the problem, just run isAttendanceReport() on its own and plugin

How can I do that... I have tried but how do you see what the output
is? I have tried just echo ing it, print_r, var_dump ...

Just to be sure, how are you determining that your code does indeed goes to
the 'else' branch and return 1? Because if it does indeed return 1 then:
echo isAttendanceReport(1); // should display 1
For debugging something like this I would put in echo statements (or
trigger_error()) all over the place to indicate which part of the code is
being executed.
> however the calling statement just does not seem to work....
If isAttendanceReport() did indeed return 1 then the if-clause in
displayMenu() would be obviously be true and would obviously execute (unless
you have uncovered a bug in PHP). So the most likely explanation is that
isAttendanceReport() is NOT returning 1.

How does $dba['results']['attendance_report'] get assigned? What variables
does it rely on? What variables are present/not present in the case that
succeeds/fails?

By not running unnecessary code. In this case you seemed to have determined
that isAttendanceReport() is not returning what you think it should be
returning. Hence running displayMenu() to test for the return value of
isAttendanceReport() is unnecessary, particularly when the execution of
displayMenu() is itself subject to a switch construct. So cut through the
crap and just run isAttendanceReport() direct as in:
echo isAttendanceReport(SOME_VALUE_FOR_SID);
If you still don't get any joy then dig deeper. What isAttendanceReport()
returns is solely dependent on:
mysql_num_rows($dba['results']['attendance_report'])
As I have hinted above you have to find out what code is setting
$dba['results']['attendance_report'], what factors (variables) will affect
that code, and even try running that bit of code direct instead of going
through isAttendanceReport() (which itself is adding another layer of
unnecessary complexity).

Most of isAttendanceReport() comes directly from the code of
AttendanceReport() --> the function that fulls the report... the only
thing that it does does diffrently is is check to see if the data is
there instead of displaying the data.
When I was doing the DEBUGGING I had put " echo 'got here(line
number)'; " statements during the code and it displayed going through
out the isAttendanceReport().

Have you tried other URLs? With and without a query string? Could you give a
_real life_ example of a URL that doesn't work?

One possible explanation as to why it doesn't work within PHP but works with
something else is that the target site looks at the user-agent in the request
header and if it finds something it doesn't like (eg PHP) then it redirects
the request to http://localhost/ or something. That way the target site hopes
to prevent bots from harvesting its data.

Hi There,
I recently installed PHP and have two things going on that I can't seem to
rectify or solve.
If I may use the collective knowledge of PHP users/developers on these
groups I would be grateful.
First some info on my setup:
OS : Windows 2000 Server
Webserver :IIS6
PHP : 4.3.10 (extracted zip version from php.net into folder "c:\php4")
phpinfo() page : www.jikade.com/test.php
The problems:
1) I want PHP to look for my php.ini file in the php folder (c:\php4) but it
refuses to do so. Setting PHPRC doesn't help and this setting actualy won't
show in the summary of phpinfo() in the environment section. I changed the
PATH environment variable to include "c:\php4" but that doesn't help either.
Putting the php.ini in the "c:\winnt" folder does work and then I configure
PHP through this file. Otherwise it won't load *any* php.ini file and use
defaults, or so it seems.
What I want to accomplish is that PHP finds and uses the php.ini file that
resides in the "c:\php4" folder
2) Some modules won't load, php_mcrypt.dll for one. I tried setting the
"extension_dir" (extension_dir = "c:\php4\extensions") but that doesn't
help. Copying the dll to the "c:\winnt\system32" folder doesn't work either.
Some modules do load however (php_df.dll loads fine from the same location),
it's just some modules that don't/won't. Examples are: php_mcrypt.dll,
php_mhash.dll and php_xmlrpc.dll.
What I want to accomplish here is that modules can load (obviously) :-)
Any help on these matters will be appreciated immensly!
ps: I used a MailExpire temporary email address to be able to post on this
newsgroup. Don't know if that's a faux-pas around here but I tend to be
realy carefull with my real email addresses on newsgroups due to spam
problems. If people say it's ok to use my real email address then I'll use
that one in future posts. Sorry for any inconvenience caused.

not sure if its a typo but the array shows "userfile" and your variable
array shows "user"
it looks like the file isn't being passed at all, double check if you have
any typos.. type is blank which should at least show the mime type..

I have written a function to generate and store a salt data for a
session cookie. I haven't written the MySQL code, so that is absent.
Basically what I am trying to do is make it so that if there is no
value submitted for an argument, I want it to fall back to the
defaults set up in my config.ini file. This file is successfully
parsed into the array "$_SETTINGS". I have no problems doing this. I
get an "Unexpected T_VARIABLE" in the line with the function
definition. I know this means that I've got a variable call in the
wrong place, but I don't know why it thinks it is wrong.
Can you not default to variables in a function? Or am I just writing
it incorrectly? Please enlighten me on this, I'm pretty much stuck.
--CODE SNIPPET--
function create_salt_data($destination =
$_SETTINGS['session.salt_var'], $prefix =
$_SETTINGS['session.salt_prefix'], $crypt_method =
$_SETTINGS['session.salt_crypt']) {
$crypt_command = '$salt_data = ' . $crypt_method . '(uniqid("' .
$prefix . '"));';
//Did compiling the salt together fail? If so, return failure.
if (!eval($crypt_command)) {
return false;
}
// $salt_data = $crypted_salt;
if ($destination != 'return') {
$_SESSION[$destination] = $salt_data;
return true;
}
else {
return $salt_data;
}
}
I have worked around it by making the defaults null, and then testing
and replacing them inside the function. It takes more code than I
would like it to, I'm trying to condense my files.
Thanks in advance!

Hi all
I am making a gallery for my Homepage. Now, I want to make little
tumbnails of my work and make a table out of them. So, to not put them
all in a row, what whould make the site unreadable, i have to put them
in a little table, an i think 4 in each row would be ok.
I like to read out the pic's name etc. out of a mysql table. But how do
make the script to write a </tr> after it read out 4 entries of a mysql
table?
Thanks in advance :)

What I generally do is use the mod (%) operator to keep track of where
it is. It returns the remainder of the divisional operator, as such:
0 % 4 == 0
1 % 4 == 1
2 % 4 == 2
3 % 4 == 3
4 % 4 == 0
5 % 4 == 1
6 % 4 == 2
etc...
That way, you have a guaranteed 4-member looping variable.
Try something like this:
<?
$result = mysql_query("SELECT * FROM foo ORDER BY bar");
$count = 0;
while ($row = mysql_fetch_assoc($result)) {
$loopcount = $count % 4;
if ($loopcount == 0) {
echo "<tr>\n";
}
echo "<td>{$row['baz']}</td>\n";
if ($loopcount == 3) {
echo "</tr>\n";
}
}
?>
The only problem is that at the end of the while() loop, if you want to
have perfectly-formatted HTML, you need to figure out if it left off in
the middle of a row and fill with N empty <td></td> tags.
Also, if there's a better way to do this, I'm all ears. This is the way
I've done it for years, but it /is/ a pain to do.
Anyway, HTH!

Heh, that looks better than what I usually do, but to put a clean finish
on it, you could do something like:
$loopcount = $count % 4;
if($loopcount > 0)
{
for(;$loopcount < 4;++$loopcount) echo "<td>empty cell</td>\n";
echo "</tr>\n";
}
That should work, and could be cleaned up a bit better I imagine...

CSS and floats are your friend:
<style><!--
.gallery_image {
width: 200px;
float: left;
margin-right: 1em;
margin-bottom: 1em;
}
.clear {
clear: both;
margin: 0;
padding; 0;
height: 0;
}
--></style>
<!-- Loop over this, adding image sources and captions -->
<div class="gallery_image">
<img src="..." alt="..." /><br />
caption here...
</div>
<!-- End of loop -->
<div class="clear"> </div>
The beauty of this method is:
* As the browser window expands, more images are allowed per row
* No need to muck about with closing rows
* Separation of content from layout
The cons:
* If you have some images landscape, some portrait, you may get some
uneven spacing amongst rows. This can be solved by adding a height
attribute to the style, but if your captions are of variable length,
this could cause some strange display issues on longer captions.

Hello,
I have the SOAP PEAR package set up correctly to the point where I can send a
request and get a response. However, my web service is designed to return XML
back to the caller. When I do this, all of the tags have their "<" and ">"
converted to < and >. I have spent much time searching the web for an
answer to this, but have come up empty handed. If anyone knows how to solve
this that would be great. Also, if anyone has experience writing a web service
in PHP that returns XML I am open to suggestions of approaches other than using
the PEAR SOAP package.
Thanks,

Just thought I'd throw this one out there to test the waters...
This past weekend, I was fiddling with cURL to create a "bot" that could
auto-post to my phpBB message board on-demand. All was working well with
getting it to login to the board and post, but the strange part came
when I discovered that it would shear form vars at a \n character.
I never did pinpoint it to whether it was cURL or phpBB doing it, but I
suspected cURL. I also didn't do much testing outside of my application
outside of messing with every CURLOPT_* setting I could lay my hands on.
Has anyone ever run into something like this, though? I Googled to no
avail...

Are you talking about the variable you're POSTing? Does it make a
difference if you urlencode the form var? Have you tried debugging
from the server end to see what cURL is passing over? I use cURL
quite a bit, although I've never tried passing muti-line form data.

I started to put together a few classes that reads/writes files,
using the fopen() function, injunction with flock() to
lock files while reading/writing.
And I also was wrapping fopen()/flock() around copy()/unlink()/rename()
with the thinking that they needed file locking *features* while
modifying the filesystem.
I initially chose to use flock() to cut down possibilities of *race
conditions*.
Now Im beginning to question even using the fopen()/flock() way of
reading/writing
files, and instead go to file_[get|put]_contents().
As I understand it, race conditions *can* occur during the php steps
of reading/writing files using the fopen() method ->
fopen(...);
// read or write to file with fread()/fwrite()
fclose(...);
Now my thinking is that if I were to start using file_[get|put]_contents(),
and do away with fopen()/flock(), there would be no need for file locking,
since file_[get|put]_contents() is just one php operation.
I may be wrong with this assumption.
Im looking to see what others may think about file locking using php
functions,
file_[get|put]_contents()/copy()/unlink()/rename() to read/write/modify
the filesystem.
Is it even neccessary in php5?
Thanks for any insight that you can provide...

Which type of engine would y'all recommend for a user/customer and
session data storage database? I'm currently using MyISAM, but I just
was curious to see if you guys could tell me if you know of a better
one, or tell me what you use.
TIA,

> $a = $b ^^ $c
You sure? It didn't work for me, and it isn't listed in the PHP manual.
I used:
<?php
var_dump(1 ^^ 0);
var_dump(0 ^^ 1);
var_dump(0 ^^ 0);
var_dump(1 ^^ 1);
?>
to test it and got a syntax error.
I suppose you could use the bitwise one as a bit of a hack, so long as
you 'boolean-ised' both arguments first.
eg $a = (!!$b) ^ (!!$c); // or even $a = !$b ^ !$c; since xor
depends exclusively on both sides being different to each other.

Hi there I am in a bit of a dilemma, I have been leaning towards ADODB for
its speed, but I amliking to use some pear components that only handle pear db
etc .. Honest
opinions, I am doingweb applications and building a little framework for it,
will I notice any
performance differences if Iuse DB ? I have used DB alot in the past, but for
this current job had to
build a custom DBabstraction class with error handling. Let me know
--- End Message ---

Haven't done much with either of them, besides reading docs, but I'd
lean towards ADODB for its exception handling(with php5), if you need
error handling.
Having that said, I haven't really a clue what I'm talking about in
this regard, so I'll be listening in with interest.

I'm assuming PEAR error handling will come out with exception handling ?
Besides , i am using thepear syntax in adodb , i wonder if it will still work
with the components
ie DataGrid andDB_DataObjects. These tools will be highly useful, I cant see
much pear
stuff compatible withADODB
