[PHP] $_POST vars
Can one create a set of $_POST vars within a script or is that not do-able? My display portion of my script utilizes the POST array to supply values to my input screen - this works well for the first display of an empty screen, and any following re-displays if there's an error in the user's input.

If you mean an array that you got from a MySQL query (my best guess), then simply assign that array to $_POST and Bob's your slightly perverted uncle!

RE: [PHP] $_POST vars
Hi Jim,
Sure you can create set of et of $_POST vars :
e.g.
form action=myphpaction.php method=POST
input type=password name=admin_code value='Enter here..'
onclick=if(this.value=='Enter here..'){this.value='';
this.style.color='#000'}
onblur=if(this.value==''){this.value='Enter here..';
this.style.color='#555'} /
input type=submit VALUE=Execute /
/form
So that admin_code var is passed to myphpaction.php as post and shall be
access there via $_POST[admin_code ];
However, note that in PHP all the output buffer is flushed actually,
ONLY after the script execution is terminated.

Given this (and noting the fact that this was your suggestion to the OP) you're creating the problem you're trying to avoid by using an arbitrary array in the place of $_POST. My response to the OP was simply answering the question. He has a section of code that uses $_POST and he wants to know if he can populate that within his code rather than needing it to come from a request. Why he didn't just try it is beyond me, but all this talk of best and bad practice is all beside the point. keep things cleanly separated and you'll thank yourself later imo. also when someone is asking a question of this nature, obviously this is the most critical time to tell them about bad practices rather than just the obvious, yes, of course you can do that otherwise people asking questions won't get much more mileage from this list than a google search.

While I don't necessarily disagree with you as far as abstracting the source of data goes, but it's never prohibited, it just considered bad practice. considered a bad practice means prohibited for most groups ive worked with. This isn't any of the groups you've worked with, this is the wide world and it's full of possibilities. lol youre right, and none of the groups ive worked with have been part of this global community, so these must be strictly new possibilities we're discussing on this thread... Personally I've never understood this thou shalt protect the superglobals attitude. They're arrays, nothing more, use them in whatever way you want to. They're not sacred, endangered or likely to be overcome with the urge to kill you if you modify them. If your code changes its behaviour depending upon whether the data you're dealing with has come from within or without your code I think you have bigger style issues to address. the reason it's a bad practice is it undermines an assumption that $_POST is only being populated by the environment, which in the case of $_POST is coming from a form field, ajax / curl request etc. as soon as that assumption is thrown out the window debugging becomes more involved trying to track down the mysterious appearance of a $_POST var. if you really need to store arbitrary data in a supergloabal $GLOABALS is there for that; def don't stuff these into $_POST :) My idea of best practice says that data coming in from outside your code should only ever be dealt with in the first script the request hits, so you should never be hunting for where an errant value in $_POST came from. Given this (and noting the fact that this was your suggestion to the OP) you're creating the problem you're trying to avoid by using an arbitrary array in the place of $_POST. well when you build programs that are more than one script in length you'll find that data submitted by the user is often referenced further in the flow than the entry script.. read: front controller. and im not creating a problem, im avoiding a problem by not overloading the intended use of the $_POST array. My response to the OP was simply answering the question. right, don't bother to offer any insight to a beginner, undermining the benefit of a list like php-general. He has a section of code that uses $_POST and he wants to know if he can populate that within his code rather than needing it to come from a request. Why he didn't just try it is beyond me, but all this talk of best and bad practice is all beside the point. no, it's the entire point. if you ask a question on this list you should expect to get more than a black and white answer. that's how people get better quicker and that's the point of interacting with humans on the other end of the wire. keep things cleanly separated and you'll thank yourself later imo. also when someone is asking a question of this nature, obviously this is the most critical time to tell them about bad practices rather than just the obvious, yes, of course you can do that otherwise people asking questions won't get much more mileage from this list than a google search. It's bad practice for reasons that arise equally well from abstracting the source of data, as you suggested. Why, then, is it bad practice? no, it's actually a better practice. users are expected to populate arrays they create. the $GLOBALS array is expected to be populated by user scripts. The $_POST array is expected to be populated by PHP. by the time you've decided to stuff variables into $_GET or $_POST yourself you've decided to start mixing variables from your code with variables from the client. simply put these arrays are not intended to be populated by user scripts. -nathan
Re: [PHP] $_POST vars
PHP then is Truly an amazing and powerful language. I can expand the contents of the array $_POST by simply assigning a separate arry to it. Obviously if I have a duplicate element-name in my array it will override the $_POST element but that's my problem.

I like Chris Shiflett's approach, which emphasizes security. Step 1 with posted (tainted) data is to sanitize it. Clean values are then moved from $_GET/$_POST into a new array, e.g., $CLEAN, so that it is immediately clear to code reviewers, future support programmers, etc., that the data is now clean and safe to use. With this approach, $_POST is only used at Step 1 and then disappears from the remaining code; $CLEAN is used in subsequent steps. Using $_POST out in the middle of nowhere *looks* like it could be a security flaw, whether it actually is or isn't. And you know how Joel Spolsky feels about code that *looks* like it could be an error ;) But, yes, you can use $_POST just like any other array. Not a practice I prefer, but YMMV. Kirk

In your script ...
?php
print_r($argv); // Requires ini setting to set argv and argc.

print_r($GLOBALS['argv']); //
?
Once you've got the value, you can ...
$s_ConstantValue = className::$s_ConstantNameFromCommandLine;
sort of thing.

[PHP] A Starter has prob in blog script
Hello,
i has a CMS System, but want better write my website manually. Im
started at first with PHP or write a Program. I really not know what i
has to do, Google can not ask, i not know what should ask. Google with
mysql link php foreach pdo help not really.
I have for my blog two files, first is the the all entry list with a
link for the complete Entry. The file for list called bloggen.php, the
file for complete Entry called blogdetail.php. I has link the Entrys
from bloggen.php to blogdetail.php with blogdetail.php?blogid=1 or with
the other BlogID from Mysql.
The File bloggen.php run without any Problems. But the linking want not
work.
The code in blogdetail.php is:
---
?php
require_once inc/common.php;
if(isset($_POST['blogid']) is_array($_POST['blogid']))
try {
$sql = 'SELECT blogid, content FROM `bloggen` WHERE id = ' .$blogid;
$result = $DB-query($sql);
foreach ($_POST as $blogid = $result)
{
echo $result['content'];
}
$DB = null;
}
catch (PDOException $e)
{
echo Fehler: . $e-getMessage();
exit ();
}
?
---
This code should use the link which come from bloggen.php in. Example,
when i click on link (blogdetail.php?blogid=1) that the script take the
content from database for this entry. I use PDO System, the content in
database is save as HTML code. I has no error in my PHP log, only the
database should communicate with php at the website call, but they not
take the right content.

Oh, boy. Okay, here we go
Because you're doing multiple lines if the condition is met, you
need to add an opening bracket here:
if(isset($_POST['blogid']) is_array($_POST['blogid']))
try {
$sql = 'SELECT blogid, content FROM `bloggen` WHERE id = ' .$blogid;
Then you define $result as the database object reference here (and
I'm still trying to figure out why you think $DB exists at this point,
other than perhaps some botched copy-and-paste from examples):
$result = $DB-query($sql);
only to redefine it as an array value here:
foreach ($_POST as $blogid = $result)
{
so that, here, it thinks it should be grabbing $_POST values,
and that $blogid will retain the keys. So this doesn't exist:
echo $result['content'];
This is nice:
$DB = null;
}
catch (PDOException $e)
{
echo Fehler: . $e-getMessage();
You've got a lot of Fehleren in the code already. Don't worry
about the output of this quite yet.
This code should use the link which come from bloggen.php in. Example,
when i click on link (blogdetail.php?blogid=1) that the script take the

Right. Instead, try to fix it somewhat like this:
?php
// Beginning stuff here
$sql = SELECT blogid,content FROM `bloggen` WHERE id='.$_GET['blogid'].';
// Do your $DB = whatever() here. You're on your own there.
foreach ($DB-query($sql) as $row) {
var_dump($row).'br/'.PHP_EOL;
}

Good luck with the rest. You may want to just go back to the CMS,
or at least start with the basics. You may already be learning that
copying and pasting code doesn't always work but sometimes it can
be malicious code that, to an untrained eye, could really be a Bad

Yes thats right what u write. When i make bad code with copy and paste, what is with a CMS System? What i know about this code, what i know about the backdoors, what i know which door is open for the Publisher or what is with the goverment? This website is not online, i know i must learn, but with books and howtos u learn not in two weeks all, i think before we normal write perfect for the masters it need more time. I nothing has to do with writing programs but i like work with computer, and my unix servers running perfect and something i must do. Im sorry when the questions is stupid, but at one point we all must start. I try that i only post the really hard questions, but what is hard for me and hard for the masters? Have nice day.

[PHP] APC: Warming the bytecode cache with preload_path
Greetings, APC has an INI setting named apc.preload_path which I assume causes all PHP files within that path to be compiled and cached by APC as it is initialized. The documentation is nonexistent, but in this thread Rasmus corroborates my assumption (well, he doesn't invalidate it in any case): http://www.serverphorums.com/read.php?7,259956 I have enabled APC. I have restarted Apache many times. I have tried the command-line in which I am able to force APC to compile and cache files. APC is working flawlessly otherwise, caching compiled bytecode across requests. However, I cannot get any preloading to occur. I have also verified that the directory I am setting in the INI a) exists and b) matches the source files that APC ends up caching dynamically. Is there some other undocumented setting I have to enable beyond the path? The reason I need this is that when we push a new version of our site live and restart Apache, we get a few random fatal errors due to our 48M memory limit setting as APC forces the request threads to compile the scripts themselves. One of the larger pages on our site requires 29M of bytecode. Yes, I know that's insane. Part of it is Zend Framework but the vast majority is our data layer which will take some time to deconstruct to be more modular. I would create scripts to manually compile the larger scripts immediately after restarting Apache, but by then it's too late. We'll have received a few requests that die. Is there another creative solution I'm missing? Thanks, David
