Dear all,
I was reading this page
http://php.net/manual/en/reserved.variables.globals.php and I found the
following script there :
Here's a function which returns an array of all user defined global
variables:
?php
function globals() {
$globals = $GLOBALS;
foreach (array(
'GLOBALS',
'_ENV',
'HTTP_ENV_VARS',
'_POST',
'HTTP_POST_VARS',
'_GET',
'HTTP_GET_VARS',
'_COOKIE',
'HTTP_COOKIE_VARS',
'_SERVER',
'HTTP_SERVER_VARS',
'_FILES',
'HTTP_POST_FILES',
'_REQUEST'
) as $var) {
unset($globals[$var]);
}
return $globals;
}
?
I think that this script UNSETS each supergobal variable,but page says that
it returns ALL user defined vars ? Can some one tell me how that is ?
Thank you,
Ashim

I may be wrong. Not that that site hasn't been scraped by other sites

[PHP] Re: Somewhat OT - Stored Procedures
Hi. I would always recommend stored procedures, as long as there are a very few rules obeyed: - keep them simple - they should mostly implement just CRUD operations plus application-specific searches, and should not encapsulate any other logic - use just portable SQL (well, as long as this is possible) My reasoning for using stored procedures and sticking to these rules is the following: - no matter what you do, especially with PHP, you can't achieve the same performance if you generate your SQL on the fly as when you just call a precompiled stored procedure - by keeping stored procedures very simple, and sticking to the convention of packing just CRUD + specialized searches into them, plus using just portable SQL, inasmuch as possible, you can easily switch databases - in most cases, just copying over the stored procedures does the trick - for the same reasons listed for the previous point, the readability of your application is much improved - reading users_getByLogin(:login) is IMO easier to comprehend than SELECT * FROM USERS WHERE loginName = :login, without sacrificing any performance or portability, compared to using inline SQL statements as strings The consequences of not sticking to the above listed two criteria can be very bad: - packing more than reasonable logic into the database makes your application incomprehensible - for instance company_doMonthEndCalculations() is likely to include such a huge quantity of logic, that the PHP code calling it is mostly irrelevant, and you must actually comprehend both the details of the SQL in the database (in the stored procedures) and the way PHP is connecting them to understand an application - obviously harder if you have all your logic in just one place - using non-portable SQL may be quite a deterrent from porting to a new database, or may cause a lot more effort than needed, and isn't in fact justified in most cases - whereas if packing only very specific and simple operations into stored procedures allows you to keep the design of the PHP application very object-oriented, packing very much logic into stored procedures may cause your PHP code to be just an adapter to an application written in SQL, instead of being the application itself; SQL being procedural, your application will have all the flexibility, extensibility and maintainability problems that a non-OO design causes br, flj -- Fine counsel is confusing, but example is always clear.

Re: [PHP] Double method access (Hi everyone! :))
I also totally agree with Larry that if used judiciously then method/object chaining can give great results, else otherwise, can create a lot of overhead in the application.

Re: [PHP] Returning a recordset to a desktop app
Larry, Yes, the PHP script will reside on my web server along with the MySQL database. I assumed that I would call the script over HTTP, but I guess that is part of my question too. Foxpro allows you to embed controls in its forms, and one of them is a browser control. But I don't really want to echo anything to the enduser, I just want to capture the data behind the scenes, so to speak. I think I can handle that with the browser control. If I understand you correctly, when I do an echo statement or a print statement (or a return()?), it will return the data to the desktop app. And the best way to return it is in xml. I'll investigate the methods you mention for converting xml since I'm not familiar with any of them. Thanks! Ken On 3/4/2011 6:51 PM, la...@garfieldtech.com wrote: Assuming you mean that the PHP script is on a web server somewhere and the desktop app is hitting it over HTTP, it's no different than any other response. Anything you print will be sent back to the client, in this case your desktop a.. So if you want to send XML back, you'd build a string with your XML (either manually or using the DOM or SimpleXML APIs or a 3rd party like QueryPath or whatever floats your boat) and print it, just as you would HTML. Note that you may need to explicitly set headers with header() to make sure the desktop app reads it properly. --Larry Garfield On 3/4/11 5:48 PM, Ken Watkins wrote: Hi All.

And it is capable of calling any other executable on the local machine through the local OS shell - which seems to be what you are advocating. But I'm not sure how I would do that over the internet.

The statement should be at the start of every php file that has php code in it. Hi Tedd, Normally I'd agree with this but having never used the function session_set_cookie_params() before, I looked it up, and the manual says to put it before session_start(). Set cookie parameters defined in the php.ini file. The effect of this function only lasts for the duration of the script. Thus, you need to call session_set_cookie_params() for every request and before session_start() is called.

[PHP] Is 5.3.5 really that much slower than 5.2?
Hi list, I've been getting my code base ready to upgrade from 5.2 to 5.3 for all the great features and supposed performance and memory improvements, but with regular usage (ie. on my production servers) I just don't see those improvements. With 5.2 pages load on average of 2ms and consume between 256-512k of memory at peak. The same pages under 5.3.5 take on average 4ms and consume about 1.2mb of memory at peak. The only difference in the config is that 5.3 is using mysqli with msqlnd, while the 5.2 is using libmysql for mysqli. I understand that mysqlnd should make things faster and use more memory (using PHP's native memory for storing data), but these are on pages with no database connections at all. They're pretty complicated pages with very little OO and with lots of small pieces coming from file caches. I'm guessing that 5.3 might be faster in heavy OO usage, but I can't see how a big shop can simply upgrade from 5.2 to 5.3 without performance being a big concern. Those numbers might not appear big, but they make a huge difference when serving thousands of requests/s. Are there practical reasons why 5.3 is so much slower? Is there a trick to making it behave better, or do I simply have to stick with 5.2 until it's no longer supported? Is anyone else out there in the same boat? Thanks!

Hi. Thanks for all the replies.

Also, you'll want preg_match_all rather than preg_match. Yeah, I realised that quite early on in my messing about. What I have ended up with is: $regex = '/.*?/'; $found = preg_match_all($regex, $sentence, $phrases); This still leaves the quotes in the phrases, but at least I only get one copy of each phrase. I'm just trimming the quotes afterwards. Thanks for all the advice. Mark -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] $GLOBALS example script on php.net
Dear Ashley, I do follow the part when it creates a local copy of $GLOBALS. When it unsets them, is there a subtlety of unset that it ONLY unsets system defined entries? Could you please explain this ? Thank you, Ashim
Re: [PHP] Re: Regex for extracting quoted strings
Maybe this will help. $regex = '/(?=)[^.]*(?=)/'; $r = preg_match_all($regex, $sentence, $phrases);

Roger Riordan AM It's not complaining about a missing parameter, it's complaining about the lack of a specified timezone. This warning was introduced in PHP5.1, and you either need to set the date.timezone INI setting, either in your php.ini or by using ini_set(), or by passing a valid timezone to date_default_timezone_set() before calling any other date-related functions. --- Simon Welsh Admin of http://simon.geek.nz/ Who said Microsoft never created a bug-free program?

I have put date_default_timezone_set() at the start of my program, which clears up all my bugs, but leaves the bug in PHP.ini. This doesn't worry me.

PS. What is date.sunrise_zenith? I am surprised that PHP contains a function to return the time of sunrise for a given location, but I thought that latitude, longitude, date and time zone would be all you had to know. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
