[PHP] Hope any body can fix this!!!
Hi..
I made the following PHP script.. And every time I try it, it shows an error
message... I think there is a wrong with ($LogoutTime - $RightLoginTime'). So please
try to fix the error..
What I want to do is to insert a logout time and if (LogoutTime - LoginTime = 20) for
example.. then make the field LessonNumber = Its value + 1 (2 + 1 = 3 for example)
This is the script :-
?php
include(Config.php);
$link = mysql_connect($user_hostname, $user_username, $user_password);
mysql_select_db($user_database, $link);
$UserName = $_GET['UserName'];
$Password = $_GET['Password'];
$LogoutTime = date(U);
$query1 = UPDATE accounts SET LogoutTime=$LogoutTime;
$query2 = SELECT LoginTime,Distance,LessonNumber FROM accounts WHERE
UserName='$UserName' AND Password='$Password';
$query3 = UPDATE accounts SET LessonNumber=LessonNumber + 1;
$result = mysql_query($query1) or die(Query error: . mysql_error());
$RightLoginTime = 'LoginTime';
$Distance = 'Distance';
$LessonNumber = 'LessonNumber';
$LessonsTimeLimit = 30;
$query4 = INSERT INTO accounts (Distance) ('$LogoutTime - $RightLoginTime');
$result2 = mysql_query($query4) or die(Query error: . mysql_error());
if($Distance == $LessonsTimeLimit){
$result3 = mysql_query($query3) or die(Query error: . mysql_error());
}else{
echo Not yet!;
}
?
Waiting your replies..
Best regards..

This line should be:
$query4 = INSERT INTO accounts (Distance) VALUES ('$LogoutTime -
$RightLoginTime');
Hope that helps. :)

Re: [PHP] naming a directory after a user-submitted string
Here's another question, possibly easier. Possibly even bone-headed.
What kind of checking/filtering/changing do I need to do on a
user-submitted string before I can feel comfortable using it to name a
new directory in the web root on Linux/Apache? Anybody have a quick
Regular Expression they can toss at me? If so, I'd be muchly
appreciative. Or is this just a Terrible Idea That Should Never Be
Contemplated?
A file or directory name in Unix can contain any character, except a
slash. On mac OS, you also can't use a colon because that was the old mac
way of delimiting directories. I imagine windows has a similar restriction
on the backslash. I think it has to be less than 256 characters as well,
but I may be remembering that incorrectly...
Permissively, you could try:
substr(preg_replace('/[\/\:\\]/', '_', $dirname), 0, 256)
Though you may also want to be strict, and remove all non-word
characters, i.e. letters, digits, slash and underscore:
substr(preg_replace('/\W/', '_', $dirname), 0, 256)
...that will eliminate special case checks for ., .., and .*.

[PHP] Cacheing data form PHP script
Hi all, I use a HTML menu that is created from multiple database queries. This is powerfull and very extendable. The problem is that the queries have to be executed on every new page or request. Moreover, the menu won't change very often for the users. So I would like to 'cache' the HTML code that is generated. If one admin add/remove/update one menu, I need to clear the cache. At the moment, I store the HTML code to display the menu in the $_SESSION['menu_cache']['menu_id'] var. And this works well! The pages are displayed faster when the menu is in the cache, which is the expected result! What is your opinion about this? Do you see any other way to 'cache' some content? Could I use the $_ENV variable (or any other) to cache the menus accross ALL visitors/users? Thank you Vincent

If it is unique for each user, than storing it i session makes sense. If not than you can store it in some file or table in the db.

Take a look at pear::cache or pear::cache_lite and pearweb. pearweb use cache_lite to cache whole pages (when possible). To cache part of a page (or whatever). pear::cache is maybe easier to cache function calls (ie the function that generates the menu). But cache_mite is damn fast and can work with function calls too.

RE: [PHP] [posibleOT] Forcing entering te site thru index.php
The only other way I can think of doing this without sessions is to use $_SERVER['HTTP_REFERER'] to check if page request is coming from an existing page within your site or not. But I don't think this method will work 100% of times. Another approach would probably be to use single entry point controller model meaning, all pages are served by index.php. Still not sure as to how you can do this without sessions but you might want to look at frameworks like php.MVC or Fusebox that use the controller model http://www.phpmvc.net/ http://php-fusebox.sourceforge.net/ Hope this helps. -Original Message- From: Fernando M.

Perhaps $_SESSION as created by PHP is special and is tied to the session storage, whereas if it is destroyed with unset and then recreated that link is lost. That would explain the behavior.

[PHP] addslashes stripslashes
Im a little confused with these functions. How I here you ask. Well I thought I understood what they were for: Escaping characters that might cause a problem when you enter your data into a database query. i.e. \ Anyway what is confusing me is, say I have a string which contains an e.g: thats mine. I would use addslashes so that the query wouldnt upset mysql when it is entered. Viewing the data entry via phpmyadmin the data is displayed as: thats mine (not: that\s mine) Meaning that when I extract the data from the database I need to use stripslashes returning the string to: thats mine. (I thought that perhaps phpmyadmin striped the slashes when displaying the data.) However recently I encrypted some data which I stored in the database. The string contained a \ which I added slashes to when entered in to the database. But as the database appears to strips the first slash off the double slash automatically. Upon retrieving the data and strip the slashes off it, my data is now corrupt as there werent double slashes it was just a single (like it was supposed to be) and that got removed by the function instead of the extra one. As I havent had any data that contains a \ in it before Ive never noticed its not made any difference before. So Does this basically mean that there is no point using stripslashes on the data you extract from the database. Or am I just being an idiot J Thanks Will I've stopped 46,346 spam messages.

True. that's mine is already stored in the database as that's mine (w/o the backslash), and the database returns this. If you have magic_quotes_runtime on, php will run addslashes on the database output, but it's usualy off. Remember that the backslashes are to escape characters with special meaning (such as end of a string), but are not part of the actual string. They simply say the next character should be treated literaly. Or am I just being an idiot :-) Thanks Will _ I've stopped 46,346 spam messages. You can too!

Just adding to Marek's response in an attempt to make things clearer for you. I think what's bothering you is the fact that you don't see the backslashes added by addslashes in the strings stored in the database. Well, that's because they are *not* actually added to the strings; they simply tell the database to treat whatever character comes after them (them = the backslashes) as regular text, not as symbols with special meanings (such as quotes, which MySQL would normally sees as string delimiters, not actual quotes in a string of text). Since no backslashes have actually been added to the strings stored in the database, you don't need to (or, rather, should not) use stripslashes when retrieving the strings from the db. By the way, consider using mysql_escape_string or mysql_real_escape_string instead of addslashes; consult the PHP manual for more info on these functions.

RE: [PHP] addslashes stripslashes
On 28 January 2004 12:31, Will wrote: I'm a little confused with these functions. How I here you ask. Well I thought I understood what they were for: Escaping characters that might cause a problem when you enter your data into a database query. i.e. \ ' Anyway what is confusing me is, say I have a string which contains an ' e.g: that's mine. I would use addslashes so that the query wouldn't upset mysql when it is entered. Viewing the data entry via phpmyadmin the data is displayed as: that's mine (not: that\'s mine) Meaning that when I extract the data from the database I need to use stripslashes returning the string to: that's mine. Correct so far. Let's do a little visualisation, using your example string of that's mine: * Start with the string you want to insert: that's mine * You apply addslashes to escape problematic characters. This results in: that\'s mine * The database takes this string, translates the escape sequence to its unescaped equivalent, and inserts the result: that's mine So, by this process, you have inserted into the database exactly what you wanted -- in the process, it gets escaped in PHP, and then unescaped by the database. The bottom line here is, the slashes do *not* get inserted -- they are there simply to ensure that any potentially problematic characters get stored correctly. Now, when you retrieve this data, PHP takes a look at the setting of magic_quotes_runtime, and if it is On does an on-the-fly addslashes() on the retrieved value; so the result, when displayed will be: * with magic_quotes_runtime = On: that\'s mine * with magic_quotes_runtime = Off:that's mine So, with magic_quotes_runtime Off, you get back exactly what you put in, which is good for displaying on, say, an HTML page; with it On, you get a version that's good for using in, say, another database query, but needs stripslashes()ing before you display it. Now to the meat of your query: However recently I encrypted some data which I stored in the database. The string contained a \ which I added slashes to when entered in to the database. But as the database appears to strips the first slash off the double slash automatically. Upon retrieving the data and strip the slashes off it, my data is now corrupt as there weren't double slashes it was just a single (like it was supposed to be) and that got removed by the function instead of the extra one. Well, it's important to note here that the encryption of a string containing problematic characters may not, itself, contain them -- and, of course, vice versa! -- so the trick is to apply addslashes() (or whatever) to the values *inserted into the database*. This means that the sequence should be: * encrypt string * apply addslashes * insert into database The database will, as before, deslash the string as it is inserted, so that when you later retrieve the encrypted value and decrypt it you will properly get back what you started with. If you addslashes() and then encrypt, you've just incorporated the added slashes into the encrypted value -- and you have no protection against encrypted values which themselves contain quotes or slashes. As I haven't had any data that contains a \ in it before I've never noticed it's not made any difference before. So Does this basically mean that there is no point using stripslashes on the data you extract from the database. If you've correctly addslashes()ed it on the way in, then yes, there is no point -- since the added slashes never actually make it into the database. (Indeed, you may incorrectly remove slashes that were in the original data!) Cheers!

[PHP] __autoload() in PHP4
Good morning fella, Is there something like __autoload() of PHP5 in PHP4? After using PHP5 for a month, I just can't stand writing those never-ending includes and requires. Any ideas how to simulate an __autoload()? I am not afraid of a little overhead. For those who don't know - if PHP does not have some class defined, it looks for __autoload() function defined by user and checks for class definition after executing the function. If the class is then defined, PHP goes on parsing as nothing had ever happened, but if the class is not found by that time PHP sends an error message. -- Best regards, Pietuka Tevi gaida Persijas princis Tikssanaas vieta un aizrautiiga laika pavadiissana http://games.inbox.lv

[PHP] Help: arrays in a class
Hi all,
I'm having some trouble here and I hope you can help. I'm writing a class
for PHP to help track includes in a c++ source file. My class has 3
member variables:
a filename
file contents
array of files that file includes
The class definition looks like this
class clsfTreeNode
{
//member variables
var $fName;
var $fData;
var $includedFiles;
//constructor
function clsfTreeNode( $fileName )
{
$this-$fName = $fileName;
$this-$fData = file_get_contents($this-$fName);
$this-ParseFile();
print count($this-$includedFiles);
}
function ParseFile();
{
...Long Drawn Out Code Omitted...
}
};
Here's the problem. In ParseFile I call the function:
array_push($this-$includedFiles, $ifName);
where $ifName is the name of an include file I found in the code. However,
I get an error stating the first argument must be an array. So I tried
making the constructor look like this:
function clsfTreeNode( $fileName )
{
$this-$fName = $fileName;
$this-$fData = file_get_contents($this-$fName);
$this-$includedFile = array();
$this-ParseFile();
print count($this-$includedFiles);
}
and that seems to work ok EXCEPT that $fData also becomes an array and
it's contents erased! I've tried moving things around, etc but no matter
where i make $includedFile an array $fData gets screwed up. If I don't
explicitly make $includedFile an array then nothing works anyway.
I'm going out of my mind trying to get this to work, and it shouldn't be
so hard. I'm using php 4.3.4 on a WinXP machine. Any thoughts?
THanks

Don't know if the 's' is the problem, but it's a start. Also, you may
want to declare you $includeFile(s) as an array at the start of your
class. I'm just guessing here, but declaring it as such
($this-$includeFile = array()) may be emptying $this too.

[PHP] Zend Studio ESC key issue?
First, let me apologize for this not being a specific PHP question, but I can't find the answer and I'm hoping someone else here has run into this. Maybe I'm just blind, blond or stupid today. :) In Zend Studio (Zend Development Environment) for Windows (on Windows 2000 fyi), when I hit the ESC key, it hides my Messages, Debug and Output windows. This might be nice sometimes, but I find myself hitting ESC (sometimes for no rational reason) and it's driving me nuts that it hides the three windows I WANT to see and not the File Manager window, which I really don't use that much currently. Hah Is there somewhere to customize this or is there another key that brings them back quickly? I prefer keyboard use to mouse use and would prefer not to have these windows disappear in the first place, but if it were a matter of hitting ESC to temporarily hide and hitting ESC again to bring them back, that'd be acceptable. I promise to post more directly PHP related messages later, just gotta take care of this one project first.

Mcrypt can operate in four block cipher modes (CBC, OFB, CFB, and ECB). If linked against libmcrypt-2.4.x or higher the functions can also operate in the block cipher mode nOFB and in STREAM mode. Below you find a list with all supported encryption modes together with the constants that are defines for the encryption mode. For a more complete reference and discussion see Applied Cryptography by Schneier (ISBN 0-471-11709-9). * MCRYPT_MODE_ECB (electronic codebook) is suitable for random data, such as encrypting other keys. Since data there is short and random, the disadvantages of ECB have a favorable negative effect. * MCRYPT_MODE_CBC (cipher block chaining) is especially suitable for encrypting files where the security is increased over ECB significantly. * MCRYPT_MODE_CFB (cipher feedback) is the best mode for encrypting byte streams where single bytes must be encrypted. * MCRYPT_MODE_OFB (output feedback, in 8bit) is comparable to CFB, but can be used in applications where error propagation cannot be tolerated. It's insecure (because it operates in 8bit mode) so it is not recommended to use it. * MCRYPT_MODE_NOFB (output feedback, in nbit) is comparable to OFB, but more secure because it operates on the block size of the algorithm. * MCRYPT_MODE_STREAM is an extra mode to include some stream algorithms like WAKE or RC4.

Re: [PHP] chunk_split();
chunk_split();From: Benjamin Trépanier
I am using the chunk_split(); function to separe a
long long text on differents pages.
At this time, I can split the string into x sections of
2000 characters.
Now I need to show only the first 2000 .
when user click on page #2, it's reloading and
show the next 2000 characters... If he click the page
4 button, it's going to the 6000th caracters and it show
his next 2000.. etc...
How can I split this text on many pages without loosing
any characters?? Maybe the chunk_split function is not
the good one...
You'll have to look for the spaces. So you want no more than 2000 characters
per page. If you're on page x, then start at character x*2000 and start
looping backwards character by character until you find a space. Then grab
the text up until that character. remember that characters location, too,
as you'll need to use that as your starting point on the next page.
Something like this:
$start = 0;
$chars = 2000;
$page = array();
$x = 0;
$len = strlen($long_text);
while($start $len)
{
$spot = $start + $chars;
if($spot $len)
{
while($long_text{$spot--} != ' ') { }
}
else
{ $spot = $len; }
$page[$x]['start'] = $start;
$page[$x]['chars'] = $spot - $start + 1;
$x++;
$start = $spot + 1;
}
Now you'll have your start and number of characters for each page. For
example to show page zero:
echo substr($long_text,$page[0]['start'],$page[0]['chars']);
To show page 5
echo substr($long_text,$page[5]['start'],$page[5]['chars']);
etc. Throw $page into a session variable so you only have to calculate it
once.
Also, if you're pulling this text from a database or file, combine it with
the database and/or file functions so that you only extract/read the part of
the text your after instead of the whole text each time.
Hope that helps.

You're absolutely correct. I jumped the gun way too early.
My experience with replacing with amp; is that if the content already
contains entity content, for example nbsp;
Running str_replace will mess them up.

RE: [PHP] Still error messages!!
Correct Radwan, you are NOT trying to echo the queries to the screen.
However, what David is trying to teach you is simply debugging
techniques.
By echoing the actual query that the PHP pareser is using, you can see
if it is indeed what you want it to be.
This way, you can debug the code yourself, instead of posting it to a
list for help.
That way you cut down on the number of email messages I receive and also
learn something in the process.
Now, echo it to the screen and see what it says :-)

Re: [PHP] Variables not working!
Try this for a generic fix if it is the globals issue:
Place this somewhere to set to TRUE or FALSE when needed
$GLOBAL_FIX = TRUE;
use an include on every script:
if($GLOBAL_VARS_FIX) {
if( phpversion() = '4.2.0' ) {
extract($_POST);
extract($_GET);
extract($_SERVER);
extract($_ENV);
extract($_COOKIE);

Re: [PHP] (WEIRD problem) Not following directories!!! (0t)
Hey Andrew, First, note that that is an apache problem, not PHP. Yep, thats why I put the Ot in the subject line but since you cant have PHP without a webserver and apache is the most popular on the list or the net...I was hopeing someone else had this problem and could guide me In httpd.conf add Option Indexes to the folder (root for whole site). That will produce a file list of the directory. Thanks, will try that right now. Or, put in a 'default' document (ie: index.html) that will produce the output when people browse to the directory. Will try that too. Directory browsing is normaly disabled in web servers (from experience, apache and IIS). See? didnt know that. Learned something new. HTH Sure did. Thanks. Cheers, -Ryan Andrew Hi, Heres a totally weird problem, I created some folders on our server (which we are accessing only via ip as the domain has not been resolved) but I get an error when i try to access the folder(s)! eg: (I created this folder) ryan and i try to access it like this: http://208.234.29.220/ryan/ and it gives me this error: You don't have permission to access /ryan/ on this server. Which is totally weird coz I have NOTHING in that folder right now... not even a .htaccess file What could be wrong?

Re: [PHP] Still error messages!!
I assume you are using another page with a form to enter the username and
password?
If so:
add as the first line of your script right after the ?PHP
phpinfo();
Run your application, scroll to the bottom and look at the php variables
and make sure that your are asking for $_GET[Username] and
$_GET[Password] are what the script sees
If not:
You may have to run just that page
with http://whatever/whatever.php?Username=whateverPassword=whatever to
see if the problem is in the form or not

Correct Radwan, you are NOT trying to echo the queries to the screen.
However, what David is trying to teach you is simply debugging
techniques.
By echoing the actual query that the PHP pareser is using, you can see
if it is indeed what you want it to be.
This way, you can debug the code yourself, instead of posting it to a
list for help.
That way you cut down on the number of email messages I receive and also
learn something in the process.
Now, echo it to the screen and see what it says :-)

Thank for your reply..
But I'm not trying to echo these queries.. What I'm trying to do is :
To UPDATE a value in the database (Login_Time and Logout_Time) and then
caculate the distance between them and put it in (Distance) field.. then
after that program the PHP file and put in it a LessonLimit value.. if
the LessonLimit is the same of the Distance.. then make a value in that
row
(LessonNumber) = Its currently value + 1 (So for example : is
LessonNumber = 2 then it must be 3...Etc..)
Hope you got my meaning..
The error that is displayed always is : Query error: You have an error
in your SQL syntax near '0') WHERE UserName= AND Password=)' at line 1
Also when I put the right UserName and Password.. the same error!!
So also there are some other errors.. please see the whole script..

Re: [PHP] amp
From: Gerard Samuel [EMAIL PROTECTED] You're absolutely correct. I jumped the gun way too early. My experience with replacing with amp; is that if the content already contains entity content, for example nbsp; Running str_replace will mess them up. Depends how you define mess them up... If you want to display nbsp; literally on a web page, then you need to write amp;nbsp; in the source.

True, but the bottom line is

Me personally, I rather keep it in its simplest form nbsp;
For example, if you run amp;nbsp; through str_replace('', 'nbsp;', $foo)

The point Im trying to make, is to watch out using str_replace() to convert

Here's a part of the array's hierarchy for an example: grouping (array) - owner = 'name' - message = 'text' - package (array) -- 1st package (array) --- box = $boxTypeID --- inspector = $employeeID --- contents (array) $productID = $quantity So, for example, if I want to access the contents of the third package: $array_of_productIDs = $grouping['package'][3]['contents']; Great for organization, but seems prone to inefficiencies. For example, I need to look though each Package for a Product ID to find how many of that Product that have been Packaged, compare that with the quantity of that Product ID in the work order, and display to the user the quantity that hasn't yet been packaged. I'm also concerned about the memory usage for such a deep array; would it take more memory than the same data broken up into many, simpler variables? I've thought of using simpler variables (e.g., $package1, $package2, $p1contents, etc.). However, since there are many pieces of structurally-similar data (the Contents of a Package could have any number of Product IDs and and Quantities), and some elements have many pieces of related data (both a Box Type and Inspector for each Package), arrays seem to be the logical choice. Am I worrying about this too much? ;-) Are arrays the best solution for this sort of problem? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Still error messages!!
Now I fixed the error message.. but the problem is in Distance = 0
always.. because the LoginTime is a string.. I fetch it but the same thing!!
This is the new script :
?php
phpinfo();
include(Config.php);
$link = mysql_connect($user_hostname, $user_username, $user_password);
mysql_select_db($user_database, $link);
$UserName = $_GET['UserName'];
$Password = $_GET['Password'];
$LogoutTime = date(U);
$query1 = UPDATE accounts SET LogoutTime=$LogoutTime;
$query2 = SELECT LoginTime,Distance,LessonNumber FROM accounts WHERE
UserName='$UserName' AND Password='$Password';
$result2 = mysql_query($query2) or die(Query error: . mysql_error());
$row2 = mysql_fetch_row($result2);
$query3 = UPDATE accounts SET LessonNumber=LessonNumber + 1;
$RightLoginTime = 'LoginTime';
$Distance = 'Distance';
$LessonNumber = 'LessonNumber';
$LessonsTimeLimit = 30;
? pre ?
echo $query1;
echo $query2;
echo $query3;
? /pre ?
$query4 = UPDATE accounts SET Distance= . $LogoutTime - $RightLoginTime .
- LoginTime WHERE UserName= . $UserName . AND Password= . $Password .
);
$result4 = mysql_query($query4) or die(Query error: . mysql_error());
$row4 = mysql_fetch_row($result4);
? pre ?
echo $query4;
? /pre ?
if($Distance == $LessonsTimeLimit){
$result3 = mysql_query($query3) or die(Query error: . mysql_error());
}else{
echo Not yet!;
}
?
So why it is making the Distance value = 0 and it doen't update the value in
the database. (Because it must update the value in the database by it)

[PHP] working with files
hi,
i have problem with writing a reading to file
i want to write emails in files. like this
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
etc..
this is how I write to the file
$handle = fopen($filename, a);
fwrite($handle,$email\n,128);
fclose($handle);
ok it writes everything just fine but now i want to read the file line by
line and print line by line.
this is how i do it.
?php
$handle = fopen ($filename, r);
do {
$data = fread($handle, 128);
if (strlen($data) == 0) {
break;
}
print ($databr);
} while (true);
fclose($handle);
?
the problem i get then is everything is printed in one line.
any help is appreciated.

You are not executing this query anywhere in the script
$query2 = SELECT LoginTime,Distance,LessonNumber FROM accounts WHERE
UserName='$UserName' AND Password='$Password';
$result2 = mysql_query($query2) or die(Query error: . mysql_error());
$row2 = mysql_fetch_row($result2);
Great that you used this to get the results in a row but you need to
reference the row in your script
$query3 = UPDATE accounts SET LessonNumber=LessonNumber + 1;
Instead of
$RightLoginTime = 'LoginTime';
use
$RightLoginTime = $row2[LoginTime];
but you need to do a mysql_query for the $query1 and get that value frst
Instead of
$Distance = 'Distance';
use
$Distance = $row2[Distance];
Instead of
$LessonNumber = 'LessonNumber';
use
$LessonNumber = $row2[LessonNumber];
The user comments on the online manual are a very good starting
point for basic programming steps needed to accomplish a task
If you would have taken the example on that page you would have
seen the steps needed:
set your query string
execute the query
get the resultset into a variable
This is the norm for all mysql php programming just putting a
$Distance='Distance'
does not tell php that what you really want it do read the database and
place the value of
Distance into $Distance
-Dave
$LessonsTimeLimit = 30;
? pre ?
echo $query1;
echo $query2;
echo $query3;
? /pre ?
$query4 = UPDATE accounts SET Distance= . $LogoutTime - $RightLoginTime .
- LoginTime WHERE UserName= . $UserName . AND Password= . $Password .
);
$result4 = mysql_query($query4) or die(Query error: . mysql_error());
$row4 = mysql_fetch_row($result4);
? pre ?
echo $query4;
? /pre ?
if($Distance == $LessonsTimeLimit){
$result3 = mysql_query($query3) or die(Query error: . mysql_error());
}else{
echo Not yet!;
}
?
So why it is making the Distance value = 0 and it doen't update the value in
the database. (Because it must update the value in the database by it)

[PHP] Re: Performance of multidimensional arrays vs many variables
Hi John If you have a large number of Users using this system, your save map for sessions will grow in space, using some resources If it's very large pieces of information, i would advise you to store this info in a database.

[PHP] SOLVED:- (WEIRD problem) Not following directories!!! (0t)
Hey All, Thanks to everyone who replied, the problem was indexes were not defined as Andrew pointed out (and solved my problem). *Main* problem I think was, that I never installed apache totally from the start, I always depended on the big bangs where you just run one .exe file and it installs apache,php,mysql and etc for you. Very nice approach, but as you can see, you dont learn too much, the only reason I am mentioning this is coz I know I am not the only one who does this..and now I'm going to take some time out and screw around with my httpd.conf, php.ini etc files trying to make sense of them...and if you are like me...you might want to do the same.
