Re: [PHP] mcrypt trouble, still

Re: [PHP] mcrypt trouble
Dominic, I'd start by checking the libmcrypt installation. If you're building from source, prior to your installation check that [mcrypt-src-dir]/src/cipher_test runs without error. If that succedes, install libmcrypt (and mcrypt) and then attempt to test with the command line. Start by listing ciphers and modes. Then attempt to encrypt and decrypt something. Once you've verified that the underlying code is working, then attempt to list the ciphers and modes with PHP functions. In general the mcrypt examples given by the php manual at php.net/manual were enough to get me started. Note, I've experienced problems on Solaris and Linux with the modules not being found (cipher .so's). Sometimes it's as easy as setting directories in php.ini, sometimes I've had to get into the libmcrypt code. Good luck.

Re: [PHP] Slow LDA Queries
Emilio,
Few thoughts:
o Is the call syntax you're using for ldap_read() correct? The online
manual page describes the second parameter as being the base dn,
you're passing the user's username. ( getenv(REMOTE_USER)). I'm
surprised that this code works.
o The comparisons you're making: Are they comparing similar LDAP searches.
There are issues that may not involve PHP at all that could be the cause
of you're performance issue. For example, you're search could find all
entries with a cn attribute at the base dn. This could potentially be
a large number of entries. Also, if you search for something and the
attributes you reference in your search filter are not indexed performance
will degrade linearly as you add more entries to your directory.
o Session Caching. At CommNav, we've had good success with this strategy.
We store quite a bit of information in the users session. It's not
uncommon for our user sessions to grow to above 100Kb, and I've seen
them as big as 300Kb. Retrieving data from the session (i.e. the
unserialize() function) is much less expensive then going to LDAP for
every hit to the web app.
Since these thoughts are not related to PHP, you can feel free to contact
me off-list to discuss further.

the mod_ldap queries and ldap queries from a Perl CGI return very fast. On
Perl I don't notice an performance issue (with less than a couple

more). I did a workaround keeping the result on a session variable, but it's

mod_ldap stores the user's dn on the REMOTE_USER environment variable.
Here's the function. I don't know how to make it faster.

Re: [PHP] MySql or flat database using PHP ?
Dave, IMHO, a major consideration for Web apps is contention and s synchronization. If you intend to allow users to update data on in the app it becomes important to coordinate writes (with locking) so that no two users can write to the same (region) of the file at the same time. An RDBMS (MySQL, PostgreSQL) or a directory (OpenLDAP) takes care of this (as well as many other problems with data storage and retrieval). I agree with the other statements I've seen here, but wanted to add this as well. I've done it both ways and the DBMS, Directory route tends to be a better solution. This is code reuse of the best kind. My humble $0.02.

Re: [PHP] class variables and methods
Joe,
There are varying opinions on this issue. The argument for
methods is that it hides the internal structure of your class. This
is always a good thing. This means that the internals of the class
can be changed, but the user interface (the user is the programmer here)
does not change. So this alternative implementation of someclass
class someclass {
var $data = false;
function set($key,$val) {
$this-data[$key] = $val;
}
}
is no different the the calling code. In general, I tend to have an
accessor/mutator method for each 'property' that I would like to
provide access to. I'd have a method for each $key that I want to
support (this may not apply in your case).
class someclass {
var $name = false;
var $age = false;
function name() {
if(func_num_args()) $this-name = func_get_arg(0);
return $this-name;
}
function age() {
if(func_num_args()) $this-age= func_get_arg(0);
return $this-age;
}
}
Now, this gets a big annoying to code since the lions share of my
classes have the name method implementations. I've been hunting
for a way to create methods dynamically, but I've only found one.
To create class definitions on the fly and eval() them. This
works great when you've got a huge number of properties
(class/instance vars). I'll construct a static method on the
class that processes examines the class vars (get_class_vars())
and defines a class extending my implementation. The
sub class has the methods implemented for accessing/mutating
the properties I'd like to have methods for. If anyone knows
of a means to do this to an existing class (say using create_function()
or something), I'd love to hear about it.

I've been doing some reading up on OOP in PHP, and looking at some of the

$myClass = new someclass;

why write a set method when you can just as easily call
$myClass-somevar = someotherval;
Is there a reason for this?
Also, alot of the different table classes (an OOP approach to HTML tables)
stores the data in arrays, but at what point is it too much to store into an
array? Say you have a forum and the text entered for a single respone could
be quite lengthy, much less for 100 replies... wouldn't that be a bit much
to store into an array? I know it depends on the system resources, but is
there a practical limit that people follow?

$email_addr would be equal to [EMAIL PROTECTED] .

Re: [PHP] Need Regex Help
I'd take the results of file() and then
walk through the array looking for the lines for the
various fruit you're concerned with. Then I'd grab the next
two lines and process them, with something like:
$line = td align=left.46/td;
ereg('^td align=(left|right)([^]+)/td',$line,$m);
echo $m[1] . \n;
echo $m[2] . \n;
IMHO, it's bad to do this kind of thing because any change in
the content means a breakage of your processing code. I
think that using something like XML or the DOM may be a
better approach. Individuals with knowledge in this area can
speak more to this idea.
Good luck.
