Re: [PHP] Zend Framework...where to start? -- don't.

For those who don't want to read the article it's about the cost of time spent programming vs hardware. Even if a framework will run slower than raw HTML or a simple PHP page on it's own, if that framework saves you a significant amount of time developing, and the server your running the application on isn't as responsive as you like, maybe it would be cheaper just to add another server and load balance the two. A lot of frameworks include stuff exactly for load balancing making your whole application a lot more flexible and able to withstand a lot more growth without you having to write any extra code.
Re: [PHP] EXEC and SYSTEM delay
Well if the server your running on is linux based (and I haven't tried
this) you could try adding a nohup and background the task for example
rather than doing:
system('updatedb');
try
system('nohup updatedb &');
It should background the task and let it continue running even when the
php script finishes it's execution. Like I said I haven't tested it. As
a side note I used 'updatedb' in the example because it was the longest
running task I could think of off the top of my head and requires root
priveledges... You really shouldn't run your scripts as root. *A public
server announcement*

Re: [PHP] What type of barcode used for document management system ?
As a matter of fact... For a while I was using a barcode generator to test out inventory system before getting them professionally made. I personally chose to go with Interleaved 2 of 5 as our barcode scanner was able to read them accurately and it was the same format as our campus ID cards. The trick with this is that it only supports numbers. Code128 has three different encoding tables, table B which is most commonly used, includes the characters 0-9, A-Z, a-z and a handful of symbols which I don't remember of the top of my head. I used a class someone else made which can be found here: http://www.phpclasses.org/browse/package/2176.html The code itself is quite ugly but as it was only needed temporarily it worked. It might be a good starting point for you though. aveev wrote: Hi, I'm new to using barcode I want to create an online registration in my application, where the user can fill in the form and the application will create a pdf file of the form with the barcode inserted on it.

I'm using fpdf to create the pdf file and for the barcode, I'm still looking for suitable solution. I don't know what type of barcode I should use for this purpose (I've browsed internet and found out many types of barcodes..e.g 39, 93, ean-13, c128, etc).

Re: [PHP] how to strip empty lines out of a txt using preg_replace()
The following snippet is untested and using Ash's regex (it is accurate
\s matches any white space). $content is what is getting stripped of the
new lines and $filtered is the cleansed output. See if that does the
trick for you.
$lines = str_split(PHP_EOL, $content);
$filtered = '';
foreach ($lines as $line) {
if (!preg_match('^\s*$', $line)) {
// Splitting on the PHP_EOL characters cause it to be removed be
sure to put it back
$filtered .= $line . PHP_EOL;
}
}

The regex that would match a line containing only whitespace would

like this:
^\s*$

Are the lines actually whitespace, or are they actually tags that
are inserting lines to format the page for HTML display?

Re: [Fwd: [PHP] Sessions in databases]
If you are distributing your application over multiple servers, using a database for session tracking allows a user to continue there session regardless of which server their request bounces too. It prevents the need for 'sticky' network connections which time out anyways. Databases can make scaling applications to enterprise size considerably easier. There are other file based solutions that are dirty and require you to play with file locking and all that nastyness. You also don't need access to the php.ini file to implement session in a database, check out http://php.net/session_set_save_handler Il pinguino volante wrote: (There were some erroros in the previous email, I'm sorry) Hi to all.

Re: [PHP] Copy Function Errors
It sounds to me like your problem is now about the authentication. By
default most linux distributions do not give apache a password. I
personally think using apache would be a bad idea. How about creating a
user on the linux box your trying to put the files on to make it's
primary group apache (make sure the group can write to the folder you
are putting the files in) and give it a password that is a random string
of 20 characters (http://www.goodpassword.com) that only your script knows.
Try testing to make sure you can ftp to the server using a normal ftp
client (ftp for the linux command line or http://filezilla-project.org/
is a good one if your using windows) using the account you created. Make
sure you can put files in the directory you will be with the script.
If this all works and your script using the new account is not, I'm sure
we can help you debug it further :). Good luck!

Re: [PHP] Copy Function Errors
You need to test using regular FTP, SFTP goes over SSH, while the PHP
script your trying to use is making use of regular old FTP. Make sure
that the linux machine has the ports open for FTP and that you have an
FTP server running on it (SSH is not one).

I've always used a version field (just an incrementing id) rather than an effective date field.
