Re: Re[2]: [PHP] Re: 1 web site, 3 servers, 3 countries - best practises?
This isn't about redundancy, it's about enhancing the experience for customers physically located thousands of miles away from the server they are trying to access. So, bring the content closer to them and drop their wait times massively. It's easy for those of us sat on the end of cable connections to become complacent about this IMHO (i.e. the Internet is fast enough now that you don't need to do this), but in reality that's not really yet the case. Here is something I have done in the past to speed up php/mysql pages (should work with other databases though). Basically, I noticed that the majority of our database calls were read calls, rather than write calls. So, in all of the locations globally, I set up read-only database servers, and also replicated the php code to all of the sites, then still did all of the writes to the master server but, all of the reads from each local read-only server. Not sure if this is necessairily the best way to do things, but it worked well for me, and sped things up quite a bit. This does mean you have 2 database connections always, 1 for reading, and 1 for writing. For mysql, look more at their website for how to set up replication machines. As far as the code goes, I just have a process that straight copy's it from my master server. -Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Last visitors (SOLVED?)
I did, the problem is the client is on a box with mySql 3.23.x or 4.0.x, he is deciding to upgrade to a dedicated box but then the host he is looking at says they will charge him if they are to upgrade to mysql 4.1 (hence i cant even use sub-selects) (Sorry I didnt mention the MySql version before...didnt think it was important till now) The MySQL version should not matter for what he was saying (you don't need subqueries). I think he was saying that every time you insert a user, also insert 10 records into the users profile_viewed_log. with an empty timestamp. Then, every time someone views the profile, update the profile_viewed_log, instead of inserting into it. (which can be done with a simple query...) $SQL = UPDATE profile_log SET user_id=.$userId., date_entered='1113931530' WHERE profile_id=. $profileId. ORDER BY date_entered ASC LIMIT 1; (the date i have is a unix timestamp, but you can use whatever format you wish). I havn't tested that query, but it should work with no problem. Basically, it just updates the first record with the smallest timestamp. Then, when you want to show the user the views for his/her profile, you just exclude the one's with an empty timestamp. Your other option, which also would work well, would be to do the cron job, with a limit value on the query. IMHO this is better than 3 queries every time someone views a profile. Also, you can set the cron job to run at 3AM, when there are not likely to be many users. Hope this helps some. -Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Regards, Torsten
I have no idea why the behaviour changed (I didn't really use the
function before, either). And I see now the change in the manual that
addresses this (essentially debug_backtrace gives you __CLASS__)
If you had an actual instance of the class you could use get_class, but
alas you are using a static method call. You punk.
The only other solution that comes to mind is a little messy but it lets
you get away with no object. Instead of calling the method statically
you can use call_user_func_array() with the child class name as a
parameter. Then change the parent method to accept the child class name
as a parameter.
?php
function call_static_child() {
$drive_args = func_get_args();
/** assume that first parameter is child of class Car */
return call_user_func_array(array($drive_args[0], 'drive'), $drive_args);
}

Re: [PHP] Writing new code vs. re-writing someone else's code
Honestly, I think it does depend a lot on the language you are using. From my experience, most people who work in PHP tend to write more new code than those who use COBOL. [snip] There are *so* many legacy COBOL applications though that, yeah, I think a COBOL programmer will very rarely get to write anything new. [/snip] I agree. I was reading something that like 80% of the code out there (don't quote my numbers) is in COBOL and FORTRAN. Anyways, to answer your question, I spend about 30% of my time writing new code and about 70% of my time working on legacy code. Of course, often due to lacking comments most of the time spent with old code is just trying to figure out what they were doing. :) -Chris On Wed, 22 Dec 2004 01:13:58 +1100, Justin French [EMAIL PROTECTED] wrote: On 21/12/2004, at 9:41 PM, Eakin, W wrote: The question is, how much of your time (you, the professional PHP coder reading this), is spent rewriting/repairing old code vs. writing new code.

Yes and no... Here's what the manual has to say about this...Basically, you can't do it using ini_set, but you can do it using an htaccess file. http://us2.php.net/manual/en/ini.sect.data-handling.php#ini.register-globals register_globals boolean Whether or not to register the EGPCS (Environment, GET, POST, Cookie, Server) variables as global variables. As of PHP 4.2.0, this directive defaults to off. Please read the security chapter on Using register_globals for related information. Please note that register_globals cannot be set at runtime (ini_set()). Although, you can use .htaccess if your host allows it as described above.

if($_POST[state] != ) {
if($sqlCondition == ) {

}

Well it works great..BUT, lets say the product has a category of Coffee

In this case both Coffee AND Coffee Pots get checked when only Coffee

What can I do to this function eliminate this?

Here is the function...
// Draw Checkbox Menu
function draw_checkbox_menu($name, $values, $default = false, $parameters =
false) {
for ($i=0; $isizeof($values); $i++) {
$field .= 'input type=checkbox name='.$name.' value=' .
$values[$i]['id'] . '';
if(strstr($default, $values[$i]['id'])) {
$field .= ' CHECKED';
}
$field .= ' ' . $values[$i]['text'] . 'br
';
}
return $field;
}
This function is passed the name of the checkbox list($name), the values
that are available($values = array) along with the ones that should be
checked ($default). Parameters too , but not important.
The problem is this. The Values are formatted like this...
value1|value2|value3...etc...
I use the strstr() function to check against the $default so I can check it
if so.
Well it works great..BUT, lets say the product has a category of Coffee
Pots, but the one of the values available is Coffee.
In this case both Coffee AND Coffee Pots get checked when only Coffee
Pots should.
What can I do to this function eliminate this?
Thanks
