How would you solve this problem?
I have use this array_merge() approach mentioned in other posts for
quite some time but found that it introduced many bugs when fieldnames changed.
Ie. if the defaults come from a database table and I changed the schema it
caused undefined values during the merging and - worse - sometimes messed up the
inner workings of functions...
Then I heard of the value object approach somewhere and found that much more
solid. One would basically define a class where default values are represented
by its properties. Ie:
class vo_email extends vo {
public $to = '';
public $from = '';
public $subject = '(no subject)';
public $body = '';
...
}
the constructor can make sure that absolutly necessary values are required and
set properly - and could complain if something is not right. There could be
methods that add() or set() or change() things. These could also be inherited
from a very generic class vo so that this stuff is written once and applies
to all sorts of defaults in the program.
In my app the inherited constructor accepts arrays as parameter and assigns
their elements to the object properties and - by that - overwrites the default
settings. If elements do not match with the defined properties it will trigger
a very visible call trace.
A function like sendEmail() would then require a object of type vo_email as
parameter and would work with its properties internally and can rely on it as
the vo's constructor should have catched anything bad.
If additional logic for the input values is required, it can be added easily:
class dao_email extends vo_email {
...
public function encode_body() {
...
}
public function sanitize_mail_address() {
}
...
}
sendEmail() would then require a dao_email object (dao=data access object) as
input.

[PHP] PHP function unpack
Hi,
I'm new to the list and I've search internet and didn't find an answer
to my problem.
I'm converting a perl script to PHP and I've done almost everything.
The only part of the code that I didn't get working on PHP was:
(PERL CODE)
foreach ($b_length,$b_mac,$b_crlf,$b_crlf,$a_body) {
$d_checksum += unpack(%16n*, $_);
}
The idea is to make a 16-bit checksum of all elements
($b_length,$b_mac,$b_crlf,$b_crlf,$a_body).
I'm tried translating the code to:
$arr_checksum = array($b_length,$b_mac,$b_crlf,$b_crlf,$File_Content);
$d_checksum = 0;
foreach($arr_checksum as $check_elem){
$d_check = unpack(n*, $check_elem);
for ($i=0;$i4;$i++){
$d_checksum += $d_check[$i];
}
}
But the result is different. I know that unpack in perl and php are
different, but I cant find a way to translate the format %16n* of perl
to php and generate a 16-bit checksum.
Any help will be appreciated.
[]'s
Gabriel.

Actually the else clause is not necessary. That's one of the nice things
about exceptions. If you throw an exception, processing jumps to the
appropriate catch and never returns.
try {
// Do normal stuff.
if (!$valid) {
throw new Exception('OMG!');
}
// Do more normal stuff.
}
catch (Exception $e) {
// Print user friendly message.
// Log detailed information or whatever you're going to do.

Don't sell exception handling short; it can be very useful for processing
control. Here is an example of a sequence of user input validations and checks.
All check functions throw an exception, with the details, if they find an error.
e.g., Tag spen is invalid. Check spelling. This message is rendered so the
user can correct his/her mistake.
if(!empty($adminMiscSettingsArray['instrText']))
{
try{
checkValidTags($validHTMLtags,
allProxyTagsArray,adminMiscSettingsArray['instrText']);
checkTagMatching($emptyProxyTagsArray,$adminMiscSettingsArray['instrText']);
checkTagNesting($emptyProxyTagsArray, $adminMiscSettingsArray['instrText']);
checkTextLinks($linksProxyTagsArray, $adminMiscSettingsArray['instrText']);
}
catch (Exception $e){
$instrCheckErrorMsg = $e-getMessage();
}

[PHP] Need unrounded precision
Hi, I need to extract the first digit after the decimal point from a number such as 28.56018, which should be '5'. I've tried a few methods to accomplish this. If I use 'ini_set' I would need to know the number of digits before the decimal (which, unfortunately, I would not have access to). Then I've tried: ?php $elapsed = 28.56018; $digit = round($elapsed, 1); // rounds result is '6' $digit = number_format($elapsed, 1); // still rounds result to '6' ? What I need is only the first digit after the decimal -- all the rest could be 'chopped' or discarded but without rounding the first digit after the decimal point. Is there any way of doing this?

Re: [PHP] Need unrounded precision [RESOLVED]
Thanks Eddie, Actually while waiting for some re[lies, I resolved the problem. I realized that '$elapsed' will always have only two digits before the decimal point. Thus I was able to use 'number_format($elapsed, 2);' and to give me the desired result. Thanks for the quick reply!

[PHP] security/deployment issue
Hi everybody, i have a doubt about my security and deployment methods. Today i manage several projects and these projects are versioned with subversion. My environment is something like this: 1. The developer make some update in the source code of a project. (from your IDE, generally netbeans) 2. The developer commit the modifications to the subversion server after test it(sure). 3. The project manager sync the files from the dev server to the prod server(using rsync). Well, my questions are 2. All about the rsync: 1. For each project we have a ssh user that is used to sync the files(source code) to the prod server. The problem that i see here is that for each project i need to have a ssh account to sync these files. This is not so cool because i need to have severals actived ssh accounts in my prod server. I'm thinking about the root account to do this work. Is this a good practice? 2. Does have some another way, more better than the rsync for this deployment issue? Thanks. Augusto Morais

You could create a 'service' account that is used exclusively for transferring the files to the server. To allow this user access to the various source directories you can use something like ACL's or perhaps even regular UNIX file permissions may work if your needs aren't very complex. 2. Does have some another way, more better than the rsync for this deployment issue? Rsync should work fine, but personally I like to see exactly which changes are being deployed especially when deploying to production. While I realise this recommendation is not Open Source software, I have found it to be an excellent piece of software for this task. I use Beyond Compare which has the ability to connect over SFTP or SCP as well as regular FTP. It allows you to 'diff' the files as you go and view exact changes and you can transfer only the changes you want or whole files if you choose to. I would not be surprised if an Open Source equivalent exists. Cheers, James -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
