Your function can be reduced to a one-liner:
function generate_id($num) {
return 'AAA' . str_pad(strval($num), 4, '0', STR_PAD_LEFT);
}
If the prefix is always 'AAA' you should consider to use a numeric ID
for your database and let your database generate the autoincrement id
and use this function just for display.

While exceptions can certainly be used in this context and in a valid manner, there's a fine line between an exception and a condition. The OP was processing code that didn't appear exceptional, he was merely managing flow control of the logic. This is a condition, not an exception. Agreed! He wrote: if ( condition ) break; Although I had the impression that he expected the whole block of code to be executed and just wanted to break from this block in an exceptional situation. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] php forms - select menu selected behavior

I have the code below being used to rifle through a list of available

prechosen. More code (not included) does the saving and all that, I've check
phpmyadmin. But when the page submits, the old category appears in the drop
down as selected. If I leave the page and come back it's fine, it's just
right after it is saved. The form script is being used on itself, in that
there is only one file for the form, the submission, etc. All of the other
input elements will load the data after being saved, is it something
specific to dropdowns, or it is the way the code is being instatiated?
All help is much appreciated. Please let me know if anymore info is needed.

$catmatch = SELECT prod_cat0 FROM product WHERE dbi='$dbi';;

$catlist1 .= option value=\$id\
selected=\selected\$id/option;
} else {
$catlist1 .= option value=\$id\$id/option;
}
}
to instantiate ?=$catlist1?
The only data you need from table product is the column prod_cat0, from
table categories it's category, so you should read only the needed data
instead of using * for better performance.
Take the SQL and verify if it returns what you want it to return then.

Re: [PHP] A Tool For Building PHP Web Apps
Paul M Foster wrote: On Fri, Apr 10, 2009 at 09:01:14AM -0400, Bob McConnell wrote: From: Paul M Foster Here's a hairbrained idea I was kicking around. I object to the idea of including 15 or 30 files in a PHP application just to display one page on the internet. It makes the coding faster, but it makes the display slower and seems silly to me. So what if you had a tool or a set of tools where you could write code snippets and such, and then hit a button or issue a command, and everything you specified got written into a single file? You'd specify that this page needs to read the config, set up a database connection, validate these fields, etc. When you were done, it would write all this code to a *single* file, which the user would invoke by surfing to that page. The resulting code would be *static*, not like what results from most templating systems. So rather than specify a specific variable value in the resulting file, it would embed the PHP code to display the variable, etc. What might be the liabilities of something like that? Would there be security issues? Would there be increased difficulty in debugging? What can you think of? Programs to do that used to be called compilers. There is an entire branch of computer science and a lot of tools (lex, yacc, etc.) dedicated to that topic. I know compilers. I've coded in C for years. I'm not talking about a compiler here. It's more an aggregator. The resulting page would still be php/html, but everything needed in it would be self-contained (except the web server and PHP interpreter). Kind of like what make does, except that make typically invokes the compiler to mash it all into one executable at the end. It's not a bad idea, but there is one precarious assumption that underlies it. Can you absolutely guarantee there will never be a second, or third, or more pages on that server that will need some of those functions or classes? As soon as the site begins to evolve and grow, you will have multiple copies of many of those snippets, and when (not if) you need to modify them, you will have to find and change every single copy. So you need to ask yourself if this strategy is maintainable in your case. And will it make any real difference in the end? Good point. That's why I asked the question in the first place. Every time you revised a supporting file, you'd have to regenerate all the files that depended on it. Might be okay for a small site, but could be a nightmare for a large site. Paul You could try to substitute all your calls to include() or require() with SSI-includes and let your webserver do the aggregation then. I read an article about retrieving the webservers result after performing SSI actions but before handing this over to the application server, but I can't remember where ... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Question about template systems
Matthew Croud wrote: Hello, First post here, I'm in the process of learning PHP , I'm digesting a few books as we speak. I'm working on a content heavy website that provides a lot of information, a template system would be great and so i've been looking at ways to create dynamic data with a static navigation system. So far, using the require_once(); function seems to fit the bill in order to bring in the same header html file on each page. I've also looked at Smartys template system. I wondered how you folk would go about creating a template system ? Smarty is a good choice, although some people might prefer other templating systems. This is kind of a religious question like with programming questions in general. But I guess that most people would advise you to use an existing templating system instead of writing one on your own. My second question might be me jumping the gun here, I haven't come across this part in my book but i'll ask about it anyway. I often see websites that have a dynamic body and static header, and their web addresses end like this: index.php?id=445 where 445 i presume is some file reference. What is this called ? It seems like the system i'm after but it doesn't appear in my book, If anyone could let me know what this page id subject is called i can do some research on the subject. Have a look at the PHP manual and be sure to bookmark it! ;) http://www.php.net/manual/en/ The ID you mentioned is a query. id=445other_id=653 would be a querystring. To retrieve data passed via this querystring you can use $_GET (http://de.php.net/manual/en/reserved.variables.get.php).

[PHP] colored text in images
Hi list! I like to generate a larger image from different tiles. Each tile should have a text on it which should be red for better readability. I figured out how to compose the larger image but got stuck when to color the text. I tried the following code: $img = imagecreate($w * 100, $h * 100); $tile = imagecreatefromgif($tile_name); $red = imagecolorallocate($tile, 255, 0, 0); imagestring($tile, $font, $gebilde_x, $gebilde_y, $gebilde, $rot); imagecopy($map, $tile, $dst_x, $dst_y, 0, 0, imagesx($tile), imagesy($tile)); header(Content-Type: image/gif); imagegif($map); The text was writte an expected, just it was grey and not red.
