[PHP] Chaching issues
is it possible that the server/browser caches the output and the code changes in php are not reflected. I am having wierd problems with fixing the code, and it often not responding for a while. When I cause a parse error, the php engine does inform me, however it seems to act up on bug fixes with variables and calulations. Is that possible? Thanks in advance.

[PHP] Strange MySQL Query Problem
I already got some replies for this but it wasn't it, here is the problem: I have a simple form which queries the database based on 2 pop-up menu choices and keywords entered by the user, it passes on the variables as follows: pop-up1=choice1, pop-up2=choice2, textfield=user specified data the query is as follows $result = mysql_query(SELECT some_id, some_description, some_feature FROM '$pop-up1' WHERE some_description LIKE '%$texfield%' AND some_feature LIKE '%$pop-up2'); it tells me that column which equals to the $texfield does not exists, meaning that the query seems to be fed wrong? No idea here, $texfield and $pop-up2 are not requests for tables but matches in those tables a bit buffled I am, I've these queries before on larger web servers, this is the first time on my workstation and it does just that, simpler queries work fine... thanks in advance, R ps. the form is guarded against empty entries ps2.

[PHP] server performance
Not exactly a PHP question, but you guys will know, is there a significant performance difference in how long does it take a server to find files as the directories become more nested, eg. 1. file index.php uses images from directory DIR vs. 2. file index.php uses images from directory images/DIR vs. 3. file index.php uses images from directory files/images/DIR Thanks in advance, R --__-__-__ eat pasta type fasta -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] number of files in a dir vs. performace
I'm using mysql to hold references to image files then served on my pages via PHP. I have typically a set of two files: thumb and a large original, on occasion there is also a variant inreasing the set to 3 per image currently I am holding all of the files in 1 directory since the DB can keep track of them, however their number has grown to over 400 at this point my issue is whether it would be worth it (performance wise) to split them into thumbs and works thus having 200+ files per directory as opposed to so many, I am expecting the number of images to double in the future.

Re: [PHP] redirect browser
make sure that this script is not insterted into an html document but
it's a stand alone page eg. checkstudent.php. When the student submits
their number your form should bring them here (form
action=checkstudent.php method=post) and the page will do its job.
Make sure however that there is no output (don't print to screen) on that
page except error messages in your if statements or you will get errors.
R
I had developed the web-based survey for student.
And I need to check that each only fill in the form once time.
So I write following code to check if the student number
exist in the database or not.
if yes, don't let them to fill in again.
if no, redirect the browser to the page for them to fill in.
=
?php
$db = mysql_pconnect(localhost, survey, survey);
if (!$db)
{
echo Error: Could not connect to database.;
exit;
}
mysql_select_db(survey);
$query = mysql_query(select * from surveydb where studno = '$studno');
$result = mysql_num_rows($query);
if ($result=1)
{
echo Student Number $studno already existed in the database.brbr
.You don't need to input again!;
}
else
{
header(Location: http://www.XXX.edu/index.php;);
exit;
}
?
=
the code can check the student no. are exist in database or not
but the browser don't redirect to the page if student not exist
in database and display the following error code:
Warning: Cannot add header information - headers already sent
by (output started at c:\html\html\check.php:4) in
c:\html\html\check.php on line 42
I had no idea about this.
Can anyone tell me what's wrong of my code?
Thx!
Joe

Re: [PHP] append line to text file HELP !!!
check the read/write permissions in the folder the file is located in, they should be set to read/write/execute or th file will not be created, you might also want to use this format to open file $fp = fopen(your/path/goes/here, a); your code would look like this: ? $fp = fopen(your/path/goes/here, a); $string_to_write = $newmail . \n; fwrite($fp, $string_to_write); fclose($fp); ? --__-__-__ eat pasta type fasta -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Redirecting
Seriously, I've tried using header(Location: http://www.php.net/;); but it returns an error saying that the headers are already set. this function will not work inside an html file or of you ECHO anything to the screen prior to its execution. An effective way to use it is as a page which processes and sends back the variables. --__-__-__ eat pasta type fasta -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Login with Text Files
Two things,
if you gonna use files for such things it might help to follow such
format inside the file
[use]=somebody
[password]=theirpass
it might be easier if you have the file named after the user and it sould
store the pass
eg. somebody.txt
then have php check for the file with file_exists(),
if the file is there open it via fopen check if the password = the pass
written in the file
else
tell em to go away
still, it might be a good idea to learn too it with mySQL
Why do you even bother? Just name your file SFISFWEF.html and have that
as your password. If security isn't important, then don't use it at all.
And please don't program anything for anyone else.

Subject: [PHP] Login with Text Files
Hi guys, I'm trying the following code and the problem is that I
always
get the denied page...
What I'm trying here is to make a login thru a text file. The logins
are
in one file named login.txt, and the passwords are in the file called
pass.txt . I need Help, I can't seem to get thru here and I need it
just
like that, cause the other option would be to use my server database
which uses a PHPMYADMIN that I don't know anything about. I can't seem
to make it work, so let's stay with the text files, cause I don't need
it to be safe ( security sound ). The code goes after this message.
Thanks to all.
Rodrigo.
?php
$logins = File('login.txt');
$login_cont = count($logins);
$login_digitado2 = $login_digitado;
for ($cont=0;$cont$login_cont;$cont++)
{
if($logins[$cont] == $login_digitado2)
{
$login_indice = $cont+1;
}
}
$password = File('pass.txt');
if ($password[$login_indice] == $password_digitada)
{
header('Location:http://www.domain.com/restricted/restricted.htm');
}
else
header('Location:http://www.domain.com/denied.htm');

Re: [PHP] Re: file() and macintosh line break
just a thought, mac line break is \r you can open and save it as unix that should get rid of the weird problem, unless you need it to work for numerous uncotrolled file flow, then replacing \r might work with a FOR loop. You might have to fwrite to a new file there \r will become \n and have that be processed as a continuum of the same script. R Rodrigo Peres wrote: Hi list, I'm in a problem that is driving me crazy!!! I want open a file and puts each line into an array, but this files was created in macintosh!! so the file() can't recognize the end line and only outputs 1 element in array!! How can I solve it. I tried to fread() the file and eregi_replace the line breaks, it worked, but now I don't know how to use this to create the array! You can use split().

Re: [PHP] Help with fopen please.
check chmods, if the directory where you're saving the $fd2 is not 777
then it wont write, keep in mind it's a security issue however, use /tmp
or instead of indicating paths in the file itself have include(file with
the path to the dir) instead and put that .inc file off the reach of
apache and ftp access,
R
Shane,
You haven't told us what the problem is, only that you're having trouble
making it work. How is it not working? One other question: I have to
assume that the script is running on a different server than the one
your are trying to write to (otherwise, why use ftp?) - are you sure
that the ftp server on that system supports passive ftp? In any case,
fopen may not be the best approach to meet your needs, but you need to
tell us more about what the actual problem is.
