And is the database not readable and writeable by PHP? Just seems that
this sort of thing could be properly sorted by the right permissions

[PHP] Replace in a string with regex

Hello,

Im tryng to make some replacements on a string.

Everything goês fine until the regular expression.

 

$file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;

echo $a =  str_replace(array(7a45gfdi6icpan1jtb1j99o925,
'temp/',_([0-9])), array(test,,), $file)

 

The idea is to remove /temp and the last _1 from the file name..but im only
getting this:

screens/test_1_main.jpg

 

I want it to be: screens/test_main.jpg

 

Thank you

If you're trying to do a regular expression based search and replace,
you probably ought to use preg_replace instead of str_replace, as
str_replace doesn't parse regular expressions.

Try this one out, I think I got what you wanted to do:

?php

$file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;

echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3', $file);

   As for (1) even in my pre-OO days I was used to using a single
   generic DAO for all database access. The only time that more
   than one DAO existed was for a different DBMS engine. This
   is why I have one DAO class for MySQL, one for PostgreSQL

   single generic DAO then it just shows that you still have a lot to
   learn. For an idea on how this works take a look at
   http://www.tonymarston.net/php-mysql/databaseobjects.html


 Before I dig in on this DAO, I'm wondering, where should I, and how could 
 I,
 properly place a JOIN on this kind of pattern? Is it easy done or, on a 
 JOIN
 scenario (and I will have a lot of them) I choose probably choose another
 pattern?

 Regards,

Adding a JOIN to the SQL statement which is generated by the framework is 
very easy, as shown in my FAQ at 
http://www.tonymarston.net/php-mysql/infrastructure-faq.html#faq08. You have 
two choices where you can place the code:
(1) In the component script.
(2) In the table class, as shown in

Well, you seem to have some problems with the syntax you're using on
str_replace(). According to your script, you want to remove the
following:

7a45gfdi6icpan1jtb1j99o925- which you haven't even enclosed in quote
marks
'temp/'
’_([0-9])’- which are using weird back ticks, not quote marks

and you are trying to replace those three things with

“test”  - again, not proper quote marks

””  - not proper quote marks

Afaik, str_replace() doesn't allow for text replacement using regular
expressions, for that you'd have to use something like preg_replace()

Also, make sure your strings are correctly enclosed in quote marks, and
that the quote marks you use are actual quote marks and not the accented
'pretty' ones that are offered up by word processors, etc.

A regex which would do the job would look something like this:

^([^/]+)[^_]+\/(.+)$

That should create 2 matches, one for the initial directory and the
other for the latter part of the filename.

You can do so much more with storing sessions in a database.  For

offer more security, it also offers more flexibility.

In the second parameter, $2 is the string you'd want to replace to
test so change '$1$2$3' to '$1test$3'.

It seems like you're having trouble with regular expressions, may I
suggest you read up on them?

It should be:

 echo $a =  str_replace(array('7a45gfdi6icpan1jtb1j99o925',

Well, you seem to have some problems with the syntax you're using on
str_replace(). According to your script, you want to remove the
following:

7a45gfdi6icpan1jtb1j99o925- which you haven't even enclosed in quote
marks
'temp/'
’_([0-9])’- which are using weird back ticks, not quote marks

and you are trying to replace those three things with

“test”  - again, not proper quote marks

””  - not proper quote marks

Afaik, str_replace() doesn't allow for text replacement using regular
expressions, for that you'd have to use something like preg_replace()

Also, make sure your strings are correctly enclosed in quote marks, and
that the quote marks you use are actual quote marks and not the accented
'pretty' ones that are offered up by word processors, etc.

A regex which would do the job would look something like this:

^([^/]+)[^_]+\/(.+)$

That should create 2 matches, one for the initial directory and the
other for the latter part of the filename.

Re: [PHP] Doubt regarding session_destroy() in PHP 5

With proper permissions I'm not sure that it's any more secure but it  
certainly is a whole lot more scalable.  And it is very easy to set  
up.  A web search will yield a lot of examples of using a database.  I  
use a PHP class which I really like.

*Storing Session Data In A Database

*When you use on-disk files to store session data, those files must
be
readable and writeable by PHP. On a multi-user hosting system, it  
is

possible for other users to access your session data through the
PHP process
(but see the commentary on open_basedir in part 5 of this series.
The best
way to secure your session data is to store it in a database.

I have also studied Zend Certification Study guide by Davey Shafik
and Ben
Ramsey who said similar things in the book.

And is the database not readable and writeable by PHP? Just seems  
that

this sort of thing could be properly sorted by the right permissions
level on the file, as I assume you'd be protecting the database in a
similar manner by locking down that to specific users, and  
determining

what they could and couldn't do.

One way would be to encapsulate data access in stored procedures and
deny direct table access on the session data. That way, even though
the PHP account has access to the database where all sessions are
stored, it can only call a ReadSession procedure that requires the
session_id() as a parameter. That way, PHP would have to know the ID
of the session and could not simply SELECT * FROM sessions.

However, I haven't found many examples that use stored procedures.
Most just use regular INSERT/SELECT/UPDATE/DELETE statements, which
means that the PHP user has full access to the entire table. In that
case, it's no more trivial to scan the session table than it is to
scan the session save path looking for interesting stuff.

The nice thing about the database, though, is that you can specify  
which MySQL user has access to the sessions table.  That way you can  
really lock it down by giving access to only INSERT, SELECT, UPDATE,

 If you're trying to do a regular expression based search and replace,
 you probably ought to use preg_replace instead of str_replace, as
 str_replace doesn't parse regular expressions.

 Try this one out, I think I got what you wanted to do:

 ?php

 $file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;

 echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3', $file);



In the second parameter, $2 is the string you'd want to replace to
test so change '$1$2$3' to '$1test$3'.

It seems like you're having trouble with regular expressions, may I
suggest you read up on them?

http://www.regular-expressions.info/ is a pretty great free resource,
as ridiculous as the design is.

[PHP] putenv usage

2009-07-22 Thread Manoj Singh

Hi All,

I have a page where the user specifies in which timezone they belong to and
based on that i have to show the date  time. So I have to set the different
timezones. For this I am using putenv function like:
putenv(TZ=US/Eastern);

Now my question is whether it is fine to use putenv in the production
environment? Whether the putenv changes the timezone value globally for all
request or for the current request only?

Please advise.

What would you use for the encryption key? (I'm not saying you're
wrong here; I'm just not sure I see it.) If the key is the same for
all requests, then it is no more secure than if they were unencrypted,
other than not being able to read the contents in a text editor. If it
is based on the session_id, you can get that from the file name.
That's a little more secure, but not much. A value stored in $_SESSION
is out, for obvious reasons. I guess you could store the key in
$_COOKIE or even a use a combination of (or hash derived from)
session_id() and another value stored in $_COOKIE as the key.

It seems to me that anything you can do to make file-based sessions
secure could also be layered into a database approach, making the
database sessions even that much more secure.

  If you're trying to do a regular expression based search and replace,
  you probably ought to use preg_replace instead of str_replace, as
  str_replace doesn't parse regular expressions.
 
  Try this one out, I think I got what you wanted to do:
 
  ?php
 
  $file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;
 
  echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3', 
  $file);
 
 
 
  In the second parameter, $2 is the string you'd want to replace to
  test so change '$1$2$3' to '$1test$3'.
 
  It seems like you're having trouble with regular expressions, may I
  suggest you read up on them?
 
  http://www.regular-expressions.info/ is a pretty great free resource,
  as ridiculous as the design is.
 
 



 I tested this, with the double quotes and the curly braces around the
 middle argument (to avoid PHP getting confused) and it didn't recognise
 the matches by the numbered $1, $3, etc. I know I'm not the op who asked
 the original question, but it might help him/her?

 A custom session handler that writes to files could easily encrypt session

 think you're confusing the issue by claiming database sessions are more
 secure when what you really mean is that custom sessions are more secure
 than the default session system.

 
 What would you use for the encryption key? (I'm not saying you're
 wrong here; I'm just not sure I see it.) If the key is the same for
 all requests, then it is no more secure than if they were unencrypted,
 other than not being able to read the contents in a text editor. If it
 is based on the session_id, you can get that from the file name.
 That's a little more secure, but not much. A value stored in $_SESSION
 is out, for obvious reasons. I guess you could store the key in
 $_COOKIE or even a use a combination of (or hash derived from)
 session_id() and another value stored in $_COOKIE as the key.
 
 It seems to me that anything you can do to make file-based sessions
 secure could also be layered into a database approach, making the
 database sessions even that much more secure.
 
 Andrew

Well, if you're using a custom session handler to encrypt the files,
then you can also determine what the session file names are.  So don't
put the session id in the file name.  Maybe use a secure hash of the
session id for the filename and then use the session id as the
encryption key.

If you want to be doing date calculations within MySQL then you should

format the date for display however you wish though, which might be
worth looking at?

The -MM-DD is an ISO date format which makes date sorting simple. I
typically store dates in this format in databases (though it's usually
configurable). 

For outside-database uses, I coded a date class which uses Julian days
as its basic unit of storage. One of the issues I wanted to avoid is the
upcoming Y2K-like issue with Unix timestamps.  In many places, unix
timestamps are stored as 32 bit integers, which will reach their
capacity, I believe, in 2038. (We'll probably all have 64 bit machines
by then.) Thus, the class generally doesn't consult Unix timestamps This
makes duration and date calculations simple. If you like, I can email
you the class privately.

Store times as a separate field.

 Dear Forums,

 Kindly advice me professionally because, am getting more confused on what to 
 do about my application that needed to be online very soon.

 The fear is about Session and Authentication.

 Here are my questions.
 1.   Must a Page Authentication be done by Session or Cookie. If not what are 
 the other options.

hidden id field in the html form


 2.   How secured is Session without encoding.

encoding data? can be done, but as long as the session is stored local
to the site and not in a shared folder on a shared hosting machine,
its pretty safe
Another option is to store the session in the database


 3.   Must you encode Sessions at all time and if not what type of Session.

all depends on the application and your own level of paranoia

 4.   Is it dangerous to pass one Session on several Page.

Nope, its the essence of sessions. How else to get the session data
shared between pages?

 5.   What about locking a Session to an IP ..(tips needed)

Don't. Some ISPs host a pool of addresses and the user's IP may switch
during a single session.

 5.   Session Security tips please.

This was just discussed in another thread here on sessions today.
Search the archives.




 Thank You All.

PHP is a server side language. If you want to have php as an

 Sure that can be done.  But you will need to change the second argument
 to have double quotes so it will be parsed by PHP.
  
 Then I would surround YOUR variable with curly brackets to separate it

 If you're trying to do a regular expression based search and replace,
 you probably ought to use preg_replace instead of str_replace, as
 str_replace doesn't parse regular expressions.
  
 Try this one out, I think I got what you wanted to do:
  
 ?php
  
 $file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;

 In the second parameter, $2 is the string you'd want to replace to
 test so change '$1$2$3' to '$1test$3'.

Well, here you are trying to use a constant called test to set your

Re: [PHP] Session Confusion.

I would recommend you to get the free copy of *chapter 10: Security from
Zend Certification Study guide* by Ben Ramsey  Davey Shafik at

shorter tips:
1. You can apply session_regenerate_id() to prevent *session riding*
or *session
fixation*
2. You can keep $_SESSION['user_agent']=$_SERVER['HTTP_USER_AGENT'] and
check for logged in user to prevent *session hijacking*
3. Cookie must be encrypted.
4. Filter All inputs and validate them
5. Escape all output
6. while filtering inputs use whitelist  blacklist method

Thanks a lot Tony. Unfortunately for me, I'm seeing myself in no conditions

[PHP] unsetting a referenced parameter in a function

2009-07-22 Thread Tom Worster

though the manual is perfectly clear that this should be expected, i was a
bit surprised that the result of the following is 42

?php
function foo($a) {
  $a = 42;
  unset($a);
  $a = 'meaning';
}
foo($a);
print($a\n);
?

normally i would expect unset() to free some memory. but in this example it
doesn't and has a different behavior: it releases foo's reference to the
global $a, allowing the next line to define a local $a.

i think i'd have preferred compile error.

For the authentication you can do a form, it will pass the login
informations to some class who do the sql validation and put in session
the informations of user, but not the password, i prefer put in session
because when he close the browser the session will down

for 2 ,

On the first point, session variables are not something people can get
to from the client side unless you send them to them. What you see on
the client side is a session identifier that allows the server to
retrieve the actual session values.

for 3

You dont need encode all the session for the security, if you want more
security for some variables, encode just these

for 4

One of the intentions of the session is store informations for the easy
aplication access

for 5

I think its not a good idea, the ip can change in the middle of the aplication

[PHP] newbie question - php parsing

2009-07-22 Thread Sebastiano Pomata

Hi all,

A little doubt caught me while I was writing this snippet of code for
a wordpress template:

?php if (the_title('','',FALSE) != 'Home') { ?
h2 class=entry-header?php the_title(); ?/h2
?php } ?

I always thought that php was called only between the ?php ? tags,
and I'm pretty sure that's right, while HTML code was simply wrote in
document as is, without further logic.
Now, I can't figure out how this snippet works: I mean, shouldn't HTML
code be simply put on document, as it is outside php invoke?
Effectively if the title of page is 'Home', the HTML part is totally
skipped.

Is the if construct that does all the magic inside?

[PHP] Calculating number of checkers (draughts) possible positions

2009-07-22 Thread דניאל דנון

I am trying to calculate the number of possible checkers position - at first
without including promotion (queen/king).

Each player starts with 12 pieces in his color,
And the whole board has 32 places (64 / 2).

At first glance I thought - each place can be occupied by either black
piece, white piece, or nothing. Which means 3^32 is the answer.

Then I realized it can't be, since there is maximum of 12 pieces in each
color,
And if are for example 10 white pieces (-2), then:  +2 empty squares.

I thought about the following - We got minimum of 8 places that aren't
occupied,
So I start with 1 ^ 8 (which is 1)

I got 12 squares that have either white or nothing - which means 1^8 * 2^12
And of course another 12 taken by black or nothing
Which means 1^8 * 2^12 * 2^12 = 2^24

Its not the final number, There are a lot less, I just don't know how to add
it to the equation...

 print($a\n);
 ?
 
 normally i would expect unset() to free some memory. but in this example it
 doesn't and has a different behavior: it releases foo's reference to the
 global $a, allowing the next line to define a local $a.
 
 i think i'd have preferred compile error.
 
 

Well, you unset the reference and then you assigned 'meaning' to a local
function variable $a.  Why would you get a compile error?

 You made a mistake in your code:

 must be:

I haven't used worpress in a long time, but the the_title() function
might echo the title unless you pass the FALSE parameter, in which case
it just returns it.

 Subject: RE: [PHP] Replace in a string with regex

 No, sory, my bad typing. It's not the problem..
 I have the same on both caxses, only chnage the variable $id
  $file = screen/temp/7a45gfdi6icpan1jtb1j99o925_1_mini.jpg
  $id = '70';
  echo preg_replace('#(screen/)temp/(.+?)_1(.+?\.jpg)#', '$1'.$id,
 $file);
  Get: 0

 file = screen/temp/7a45gfdi6icpan1jtb1j99o925_1_mini.jpg;
 $id = test;
 echo preg_replace('#(screen/)temp/(.+?)_1(.+?\.jpg)#', '$1'.$id,
 $file);

 Get: screen/test

 What is wrong with having na integer on the var ?

Well, the problem here is that when you concatenate $id containing 70 on to 
'$1', you effectively end up with '$170' -- which the manual page at 
http://php.net/preg-replace makes clear is ambiguous, but is likely to be 
treated as $17 followed by a zero, rather than $1 followed by 70. Since $17 
doesn't exist (as you don't have that many capturing subpatterns in your 
pattern!), it is taken to be the null string -- leaving just the left over 0 as 
the result of the replacement. QED.

The workaround for this is also given on the page referenced above, which is to 
make your replacement be '${1}'.$id.

Incidentally, I don't really see the need for the $1, or the equivalent 
parentheses in the pattern -- since a fixed string is involved, why not just 
use it directly in both places? Like this:

   preg_replace('#screen/temp/(.+?)_1(.+?\.jpg)#', 'screen/'.$id, $file);

which completely sidesteps the problem.

Cheers!

Mike
