Fwd: [PHP] Re: Class variable value lost

[Sumit Sharma]

What I have done is declared one User class in a separate file and created
its object there only. After this included this file in all other file which
are using its object. So the object is creating only once and included in
every other file only once. Now when I over write its variable it value get
lost when I send the user in other file.

The confusion is if I have created only one object of a class and used the
same object through out the site how its value can get lost and I think this
is a separate issue than setting $_SESSION variables.

The object only exists for that instance of the script, so when the user
navigates to the next page, the object is freed up from the memory.
There are a couple of ways you could get round this:

 * don't navigate away from the page, and use AJAX calls to update
   parts of the page for the user (bad imho, as it relies on
   Javascript)
 * use sessions like Shawn recommended

If you use sessions, you can store the objects themselves as variables
into the session. You should be careful with this, as you may not want
too many sessions open with large objects in them as, depending on your
server setup, sessions could last quite a while, and there may also be a
limit on the amount of memory reserved for sessions.

[PHP] Class variable value lost

[Sumit Sharma]

Hi,

I have developed a listing site which is totally class based. Now when it
authenticates a user login and set appropriate class variables to true and
set user info in user class variables, value of all the set variables are
lost when I forward the user to members page. When I check the the value on
other page it is set to the default value of the class. Please help.

[PHP] Re: How to download and configure php mvc website locally

[Sumit Sharma]

Hi all,
The site I have download was developed using cake php. Now when trying to
access the website it is showing a blank page. As Sudheer suggested I went
to error log and noted down the errors there, which are as follows:

[Thu Aug 20 14:10:16 2009] [error] [client 127.0.0.1] File does not exist:
F:/Rabin/xampp/htdocs/favicon.ico

I think there is no file called favicon.ico but how to create this file. Is
this something related to cakephp configuration.

Regards,
Sumit

Re: Re: [PHP] change server time

[Sumit Sharma]

Hi,

What I mean is my windows time is set to local time but when I use any date
function in PHP it shows time in GMT on web browser and to change this I
have to use putenv("TZ=asia/calcutta");

Thus:

1 There is no problem with Windows time its according to IST.
2 Problem start with PHP, which displays GMT time by default.
3 To solve this I was advised to change the OS time which is already
changed.

Now I am not aware how the php date functions picking GMT time and from
where?

Re: Re: [PHP] change server time

[Sumit Sharma]

In my windows I have already selected the local time and its working fine
for window but by default WAMP server is picking GMT time so I have to use
putenv() function to change it for that page where I am using date function.
It seems there is some misunderstanding between the server and OS.

Re: [PHP] change server time

[Sumit Sharma]

Yes, I works on windows as well well. Was looking for india time zone found
it as putenv("TZ=Asia/Calcutta");. Thanks a lot, but this function does not
change the server time permanently. Any Idea about any function which does
so.


Thanks,

[PHP] change server time

[Sumit Sharma]

Hi,

   Whenever I am using date('r') function It shows time in GMT instead of
local time set on my machine. Do I need to configure the time separately. I
am using WAMP server locally.

I brought it up because suhosin catches many exploits that otherwise get
through, including exploits that allow inclusion of remote files that can
then be used to run arbitrary commands on the server, send include files
(such as the db authentication script) as plain text, all kinds of nasty can
result.

[PHP] session.auto_start

Hi All,

are there any *disadvantages of setting session.auto_start to true in terms
of system resources or security or any other*. I have set this element to
true in php.ini as follows.

session.auto_start = 1.


Millions of thanks,

I'd advise using something like mysql_real_escape_string() (assuming you
are using a MySQL database that is) on each variable of data before you
insert it into the database. You could go further and validate specific
data, so check that a field which you expect a number only contains a
number, etc.

[PHP] SECURITY PRECAUTION BEFORE SUBMITTING DATA IN DATABASE

[Sumit Sharma]

Hi,

I am designing a php website for my client which interact with database.
This is my first project for any client (I hope he is not reading this mail
;-)  ). I am a bit more concerned with database security. Can somebody shed
some light on the security measurements, precautions, and functions related
to database security in general to make sure that the data is safely stored
updated and retried from database. I have already used htmlentities(),
strip_tags(), addhashes(), and some regular expressions to check security.
Looking for help beyond this.


Thanks in advance...
