As the references show, there are two versions of the "foreach", the
one above and this:
$value)
{
echo("$key= $key value=$value ");
}
?>
Note that you can pull-out the index (i.e., $key) as well as the
value (i.e., $value) of each index. The "" is only to add a
linefeed in html.
This is a bit easier than using a for() loop.

All, I tried and tested it but wanted a solid confirmation on it. I felt foreach usage is better than manual way of next(), prev() et al. Thanks for the comments.

Dan Joseph wrote: Hi, This is slightly OT... We're wrapping up a new PHP/MySQL driven web site built on the Zend Framework. We're anticipating a couple hundred thousand members with several thousand of them coming to the site at once. I'm trying to figure out how to determine how many servers we need to support the load. I've done initial testing on a Xeon 3220 server, but we're looking at an i7 cpu based server now. Anyone know a good way to estimate load based on actually numbers compared to benchmark results from intel on a faster server? Hammer a single instance of the server with ab, get some figures on how many requests per second you can handle then divide by how much traffic you expect :) Before investing in the servers, it may an idea to cache as much as you can and let apache serve static files where ever possible, even if the cache'd files are updated once every 10 seconds it's still a huge weight off the server in high traffic sites. Simple web server config tweaks can make a huge difference too, such as dropping the keep alive right down so requests are served and workers freed quicker, likewise with mysql query cache settings and zend optimizer for PHP (+similar). Personally I tend to split setups for high traffic sites in to 3 tiers, static files on one server, dynamic + app code on another, and db on the final 3rd server - then scale up each tier adding servers as needed. In all honesty, there is no way for anybody to tell you how many servers of what spec you'll need, because the biggest factor here your PHP code and MySQL queries, if you were purely serving static files though then circa 2000 requests per second is a good guestimate.

[PHP] Redirect to
Hi folks, I know that this is not a php question, but I'm sure it some kind related to it. I need to put my public files under "public" folder, and other includes files and database config in other folder not shown to the public, but i don't know how to do that. I hope if some one show me how to achieve this. For example, this is the directory structure: /root --/includes db.php config.php --/public /index.php /images /admin --/login.php I don't want to enter (example.com/public) to view index.php file. I just want to enter (example.com) and it redirects to the public folder and shows only (example.com/index.php) in the URL.

[PHP] bug in mkdir?
Hi all,
Using 5.2.9
I'm trying to create a directory but it is being created with incorrect
permissions. I'm following the online manual.
This is the command being used:
mkdir('/srv/www/domain/data/R1276190214358/thumbs', 0770, true);
This is what is created:
drwxr-x--- 2 apache apache 4096 2010-06-10 10:33 R1276190214358
Isn't that supposed to be 0770 instead of 0750? Either the manual is
wrong, the command is broken, or I'm screwing it up (most likely).
Thanks for any help,
Mike Wright

Did the R1276190214358 directory already exist? If so, it will retain
the permissions it had, and only the thumbs sub-directory within it will
have the new permissions.
Also, is this on a shared hosting server? It could be that a security
restriction in-place is not allowing the permissions to be configured as
the directory is written, and you may have to manually update them with
the chmod() function.

No.

It's under my control.

Personally I think it's a bad idea, as those tags only work when short_tags are turned on, which itself causes problems with outputting XML from PHP. Yes it saves a little bit of typing, but with a decent IDE you can set up a shortcut for that sort of thing anyway, negating the extra seconds spent on a large project by typing the echo statement. There is also a potential issue when you move your code to a different server, as short tags are not enabled by default as of PHP 5. But, like I said, if you ask someone else, you'll likely get a different opinion on this issue. If you're the only one using this code, and the server is in your control, then it's down to what you prefer to use. If the codebase is shared, or the hosting is not in your control (shared hosting, etc) then it's probably best to stick to the regular format. Thanks, Ash http://www.ashleysheridan.co.uk

Why is the "-r" command line version different?
man php:

you
would do inside a .php file when using the eval() function.

22:01:14)

Then I tried it again on two different servers with the same result:
PHP 5.2.6-2ubuntu4.6 with Suhosin-Patch 0.9.6.2 (cli) (built: Jan 6 2010
22:03:33)

So now it get's more interesting...
A co-worker suggested to reverse the quotes:
develo...@mypse:~$ php -r 'echo md5(strtoupper("$12345678"));'
2d05c0e3d6d22343123eae7f5678e34c
Note the use of the single and double quotes are reversed. This gives me
the RIGHT checksum.
To me this version is syntactically wrong because the " would indicate in
normal PHP to pre-parse the literal $12345678 and treat $1 as some kind of
variable or something. Whereas a ' says use the literal AS IS.
Not to mention that it is completely confusing that -r gives different
results than -a and using it in a .php file all together.
IF quotes are a factor (as they seem to be), then the -r PHP
behind-the-scenes code should flip them around or something so the
developer doesn't have to be concerned with this edge case nonsense.
Sanity would dictate that all ways of executing the SAME PHP code would
give the SAME results.

It's your shell doing what it's supposed to, by replacing $12345678, when the
entire string's in double quotes, with the contents of the shell variable
12345678 (most likely nothing), so all that PHP sees is: echo
md5(strtoupper(''));

I believe that when you're running the PHP with the -r, the quotation
marks are treated as Bash (or whichever shell you're using) quotes, and
so the variable is possibly being parsed as an empty string value, which
is why reversing the quotes is having the right effect.

Looks like you and I are in the same boat! My memory these days has went to the dumps.
