[PHP] best way for PHP page
Hi, i would like to improve my coding quality when i use PHP code and for that i would request your help. in my web developer experience, i have to confess that i've never succeeded in spliting PHP code from HTML code. i mean that all my web pages consist of PHP code mixed with HTML code (for rendering pages). Some developers tell it's possible to write only PHP code for web page. i agree with them but only when those PHP pages do not render web elements (write text, display pictures, display formular, ...). the purpose of my post is to know if i can really (at 100%) split client code (display images, write text,...) from server code (move or copy data to DB, create connection objects,...) so what do you think about that ? -- Alain Windows XP SP2 PostgreSQL 8.2.4 / MS SQL server 2005 Apache 2.2.4 PHP 5.2.4 C# 2005-2008

I have two variables declared in the global scope of a script.

In the processing body of the script are if/if else blocks.

Several ways to do this (and avoid globals or a str_replace call):

The reason for this is the variable substition occurs *at the time of
assignment* - not later.
Another way, if it's not easy to have your string_b setting
conditionals all in a row like that (or if this needs to be done
elsewhere in code, as well), would be:
function assignStrA($subStr)
{
$retVal = "stuff $subStr and more stuff";

$string_a = assignStrA('foo');
} else if (cond2)

$string_a = assignStrA('bar');

{
$string_a = assignStrA('other');

This looks good

Hello,
the problem is in this part of code $key -> $value
This notation means that you are trying to access property $value on the

Just replace it with $key => $value and you will get the result as expected.

Now I understand the benefits of how Java integrates exceptions more tightly into system design. Maybe it would be a good idea to assimilate those features. The features I'm referring to is the declaration of exceptions thrown by a function. If you use a function that declares throwing exceptions and don't use a corresponding try/catch around it, the compile will fail because you're not handling the exceptions. You can either use a try/catch or forward the exception by declaring that you will also throw exceptions. Adding these features to PHP is, I think, not possible (compile-time php doesn't know what will be the extent of the system at runtime). But you can use a code analyzer that would parse metadata, such as the one used for doc-comments, and flag this problems before putting the code into production.

Re: [PHP] PHP5 Speed Issues
Hi everyone! Generaly author of the first e-mail is right. Ofcource, crawling over the code and getting out of it a few milliseconds off doesn't make it worth, but you can learn what is good and what is bad and write your code correctly from the start. Why not to use foreach ($data as &$value) if it's better - faster and takes less memory. That's just a habbit on code style. I can bet, that nobody knows or remembers that echo has alternative syntax, with works faster and is easier to write if you cave to echo a complex string with many variables and static text, for example The ordinary: echo 'Hi! My name is '.$_GET['name'].'. I'm '.$_GET['age'].' and I live in '.$_GET['country'].'.'; The alternative: echo 'Hi! My name is', $_GET['name'], '. I'm ', $_GET['age'], ' and I live in ', $_GET['country'], '.'; I have an aplication with doesn't eat all CPU, just about 50-60%, but it eats all 3GB of ram. And not because it is poorly written. It serves ~160 000 - 170 000 requests/hour, that's ~3 960 000 hits a day + another 600 000 hits to the application's WEB part. Just one server could handle, but it can't because of WEB server's FastCGI implementation (they have a patch for that soon released). Just ONE Intel E6600 server with Lighttpd and PHP can handle such load if the code is optimised and written correctly.
