[PHP] delete S3 bucket with AWS PHP SDK
Hi All,
I am attempting to delete an empty S3 bucket using the AWS PHP SDK.
Here's how they describe the process in the docs:
$result = $client-deleteBucket(array(
// Bucket is required
'Bucket' = 'string',
));
You can find the full entry here:
AWS PHP SDK Delete Bucket
Docshttp://docs.aws.amazon.com/aws-sdk-php-2/latest/class-Aws.S3.S3Client.html#_deleteBucket
Here's how I approached it in my code:
$s3 = new AmazonS3();
$result = $s3-deleteObject(array(
'Bucket' = $bucket_name ));
But when I run it, this is the error I get:
'Notice: Undefined index: $bucket_name in /var/www/awssdk/delete_bucket.php
on line 5 Warning: Missing argument 2 for AmazonS3::delete_object() in

This is line 548 in the above referenced file:
// Validate the S3 bucket name
if (!$this-validate_bucketname_support($bucket))
{
// @codeCoverageIgnoreStart
throw new S3_Exception('S3 does not support ' .
$bucket . ' as a valid bucket name. Review Bucket Restrictions and
Limitations in the S3 Developer Guide for more information.');
// @codeCoverageIgnoreEnd
}
Has anyone played around enough with the AWS SDK to know what I'm doing
wrong here? Would anyone else be able to hazard a guess?
Thanks

Re: [PHP] delete S3 bucket with AWS PHP SDK
Hey guys,
Sorry about that i should have posted the full code to give you some idea
of context. Anyway, here it is:
?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {
* $bucket_name = $_POST['$bucket_name'];*
// Create the S3 Object from the SDK
*$s3 = new AmazonS3();*
* $result = $s3-deleteObject(array(*
*'Bucket' = $bucket_name ));*
// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response-isOK()) {
echo 'centerDeleted Bucket';
echo 'br /br /';
echo 'a href=listbuckets.phpList Buckets/a/center';
} else {
echo (string) $response-body-Message;
}
//echo 'br /br /';
}
?
body
centerh3Delete S3 Bucket/h3
form name=delete_bucket method=post action=delete_bucket.php
label for=bucket_nameBucket Name:/labelbr /
* input type=text id=bucket_name name=bucket_name /br /br /*
input type=submit name=submit value=Delete Bucket /
/form/center
So, as you can see I am taking the 'bucket_value' from $_POST and passing
it into the call to S3.
When the form comes up on the web I give it the name of one of my S3
buckets. The result is the following error:

on line 67 Warning: Missing argument 2 for AmazonS3::delete_object() in

I hope that clarifies my situation a bit. Sorry for not providing that

Hi Tim,
Is the call working? Does it actually get deleted?
This could just be an issue (which I see alot) where developers do not
check for variables or preset them before usage, causing those notices to
come up (pretty harmless most of the times).

Re: [PHP] delete S3 bucket with AWS PHP SDK
Hi Aziz,
Thank you for getting back to me!
I appreciate you spotting that error.
So I corrected that
?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {
* $bucket_name = $_POST['bucket_name'];*
// Create the S3 Object from the SDK
$s3 = new AmazonS3();
*
$result = $s3-deleteObject(array(
'Bucket' = $bucket_name ));*
// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response-isOK()) {
echo 'centerDeleted Bucket';
echo 'br /br /';
echo 'a href=listbuckets.phpList Buckets/a/center';
} else {
echo (string) $response-body-Message;
}
//echo 'br /br /';
}
?
body
centerh3Delete S3 Bucket/h3

* input type=text id=bucket_name name=bucket_name /br /br /*
input type=submit name=submit value=Delete Bucket /
/form/center
script
/body

And this is the error I am currently getting:

No Problem, the issue is that you referring to the invalid post element
$bucket_name as opposed to the correct on bucket_name.
*$bucket_name = $_POST['$bucket_name'];*
Should be

A staggering number of enterprise level web applications are built with Java, add to that the possibility of writing Android apps with the same knowledge. To me the salient point is, does java has as extensive a library or set of interfaces to other packages (such as SQLite, mysql, etc)? I would say that, in general, the other teacher is incorrect speaking strictly in terms of web development. PHP has already won that crown many times over. That said, when I was in University, it was difficult to find a programming class that taught anything but Java - and that was 10yrs ago now. I chalked it up to the education bubble not being able to see what the rest of the world is actually doing. Was PHP OOP-capable at the time? Perhaps the edu-bubble was simply looking down its nose at PHP. There being lots of courses proves nothing in and of itself. 20 years ago, there were lots of PC mags you could buy, which caused some folks to say look how much better the PC is supported than other platforms. Truth was, at the time, such support was needed given the mess of 640k limits, DOS, IRQs and the like, most of which issues have ceased to be relevant. Anyway, why should one need a course to learn PHP, assuming you already know other languages. It's simple enough. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] mongo usage
Hey all,
I'm trying to pick up some basic use of MongoDB using PHP.
I seem to have hit an early obstacle that I'd like your opinion on. I try
to pass an array to the mongo insert function, but for some reason the
function does not recognize the array I'm passing. Even though I can
perform a var_dump() on the array and see the contents.
Here's the output I'm seeing (with error):
Mongo Test Page array(6) { [first_name]= string(5) Peter
[last_name]= string(6) Parker [address]= string(16) 175 Fifth
Avenue [city]= string(8) New York [state]= string(2) NY
[zip]= string(5) 10010 }

*Fatal error*: Call to a member function insert() on a non-object in *
/var/www/mongomaven/index.php* on line *36*
*
*
And here's the code:

?php
$connection = new Mongo();
$db = $connection-jfdb;
$collection = $db-addresses;

You need to have your mysql_query *inside* the for loop. Then, what are you

Also, why do you need the for loop anyway? What is it supposed to do?

[PHP] limit access to php page
Hello list, I've created an authentication page (index.php) that logs into an LDAP server, then points you to a second page that some folks are intended to use to request apache redirects from the sysadmin group (redirect.php). Everything works great so far, except if you pop the full URL of redirect.php into your browser you can hit the page regardless of the login process on index.php. How can I limit redirect.php so that it can only be reached once you login via the index page? Thank you! Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

You can DRY this up (the HTML input fields) similarly to the way you
did the validation above...
for ($i = 1;$i = $num_forms; ++$i) {
foreach ($fields as $fld) {
$tmp[]=label for='$fld_$counter' . ucwords(str_replace('_','
',$fld) . :/labelbr /;
$tmp[]=input type='text' required id='$fld_$counter'
name='$fld[$counter]' /br /br /;
}
}
Further, you could also check the validity of field right at the point
of generation and issue the error right next to the field in error,
which is usually a better UX.
$tmp[] = input type='hidden' id='num_forms' name='num_forms'
value='$num_forms' /br /br /;
$tmp[] = input type='hidden' id='requestor_email'
name='requestor_email'
value='$requestor_email' /;
$tmp[] = input type='submit' name='submit' value='Create Ticket' /;
$tmp[] = /form/div;
?
!DOCTYPE html
html
head
titleLDAP Form/title
body
?php echo implode(\n,$tmp) . \n; ?
/body
/html
You will notice that I moved the code for the form to above the HTML
section. I believe that very little PHP should be interspersed with the
HTML
-- it makes for cleaner code. You can use single quotes around form
attributes so you don't have to escape the double quotes. The names in
the
form are now arrays. This makes your life much easier when extracting the
values later in PHP.
When you check the page in a HTML5 aware brower, you will see how the
validation is done.

I do agree with Ken that you SHOULD NOT perform JS validation. It is
preferable to use php or the new HTML5 features. JS can be turned-off
by
the user which will make JS validation impossible.

This won't work if you're getting to the page via another form, since the
$_POST['submit'] is set. There two ways of avoiding this:
1) use hidden fields in each form to indicate which form was submitted
2) use a different name for each form's submit button and use that in the
above code

Hey guys,
Thanks for the input! This is pretty nice, and DOES work. I like the fact
that the fields have been into an iterative array. It's a very elegant
solution. However the problem with this approach is that if you load the
page directly it works. But if you call the page from the index.php page
you get an initial error on all fields as they are all quite naturally
empty when you first load the page.
Here's the index.php page. All it is is HTML, no php:

Why this happens when you call the ldap.php page from index.php but not

I have inherited a mess of a home-grown PHP framework that literally

I have a recursive function that reads from XML files and replaces xi:

Why do I get the notice that $xml is an undefined index?
Because it's undefined. So is $pos. From what you've written above, both are
local to includeXML. But neither is passed in as a parameter, nor is global.
You can't initialise it within the function, it seems to me.
If $xml is supposed to be appended to and grown as you recurse up and down,
then you have two choices:
1) Make them global
2) Pass both as extra parameters to includeXML
In both cases, each needs to be initialised before the first call to the
recursive function
Solution (1)
$xml = '';
$pos = 0;// Presumably.
includeXML ($file, $locale, $url, 1);
...
function includeXML ($file, $locale, $url, $level = 1) {
global $xml, $pos;
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ('repository/' . $included, $locale, (int)$level
+ $pos - 1);
}
}
}
Solution (2)
$xml = '';
$pos = 0;// Presumably.
includeXML ($xml, $pos, $file, $locale, $url, 1);
...
function includeXML ($xml, $pos, $file, $locale, $url, $level = 1) {//
Note the on the first parameter
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ($xml, $pos, 'repository/' . $included, $locale,
(int)$level
+ $pos - 1);
}
}
}
BTW it seems to me that you'll have the same problem with $included unless
there's other code in includeXML that you've omitted.

Nothing to stop your OpenWindow() function doing a submit as in:

Personally I never submit forms. I use ajax to communicate with PHP scripts and

Afterall, a string is truly only one memory allocation whereas array elements are basically multiple vars having the same name. So - how can you unset one char in a string? It depends upon the language -- while it is true that the start of a string is located at a memory address, the chars of the string are identical to the chars in an array. As such, you can view a string as an array. Each index is representative of a char (one byte) in the string. That is explicitly documented here: http://php.net/manual/en/language.types.string.php String access and modification by character Characters within strings may be accessed and modified by specifying the zero-based offset of the desired character after the string using square array brackets, as in $str[42]. Think of a string as an array of characters for this purpose. The functions substr() and substr_replace() can be used when you want to extract or replace more than 1 character. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

To answer Iñigo's comment - the OP's version is very much like an
If-ElseIF structure, and nothing like a Switch.
Just so. Perhaps those who are not grasping the point could re-read their copy
of The Elements of Programming Style by Kernighan and Plauger where this sort
of issue is covered.
See, it's all about expectations. When I worked at SLAC, there was a wise guy
there who had removed the catalytic converter from his Scirocco and who though
it clever to race up 280 from San Jose to SLAC at 100mph, sometimes
slipstreaming behind another idiot doing the same. If I look in my rear-view
mirror, I expect those I can see to be doing 70mph tops (that's what a lot of
people did 30 years ago on 280), not 100, and to make judgements accordingly.
Equally, I have certain expectations when I see a switch statement; it trying
hard to look like if-elseif-etc is not one of them.

IN your example, you are using a switch syntax that is nothing like that. I
think that your case statements are not actually evaluating the value of
$count, but are themselves evaluating to a true value that has nothing to do
with $count.
That `switch` is evaluating to true each case. It's an alternative of using
if-elseif structure.
It may be an alternative, but it breaks the principle of least surprise. If I'm
looking through someone's code, and I see a switch, I expect to see it used as
Jim described. If the writer needs a different type of logic to make a
decision, that is what the cascaded if-elseif-elseif construct is for, when the
tests don't fall into a simple set-of-values choice.
The job of a programmer is not to be clever with a view to impress those who

1.Using nested if statement {THE INTENDED BEHAVIOR}:

You don't need the count=14 part as you will *only* get there if $count=14.
$boxes = 2;

$boxes = 1;

As has been pointed out you need switch(true).
That's a strange way of writing a switch, IMO. You should be using the if

Hi everyone, I have been playing around with some code the list helped me with
a while back and I'm not grasping the concept between return and echo and the
PHP manual doesn't answer this, unless I'm missing something. There is an
example at the very bottom of PHP's return manual, but it's confusing.
It's a poor example, for one thing. As others have said, echo and return have
nothing to do with each other.
So now I'm left wondering why return will only give me the first result in an
array, but echo will give me all the results of the array. Using stuart's
example he had sent me a while back I've messed around with it and modified it
to better understand it:
function filename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
return $filename;
}
}
echo completeImageFilename($row['MLS_No']);
With the above code I only get the first image of each picture name, but when
I change return to echo, it groups and displays all the pics that have the
same picture name.
I assume that where you have function filename above, you really mean
function completeImageFilename.
Why do you think that the return you have coded above should give more than one
filename when you've written return $filename? That's one filename. You then
echo that out with your echo statement (because it's the return value of the
function), and that's what you see. If you change the return to an echo, then
instead of returning after once round your while loop, the while loop goes
round and round dealing with each filename you have in $matches, and echoes out
each one. When the while loop has completed, the function returns, but returns
nothing at all. So your original echo then does nothing at all. And so you see
the observed behaviour.

I use PHP to read all clients from all the banks and put that as hidden fields on the html page. It is very cumbersome. Well it would be. This approach doesn't scale. I do not want to read the database (which changes dynamically) from javascript directly due to confidentiality and because a lot of care has been taken to create the appropriate queries with checks and protect misuse of the information using PHP. I doubt if you can read it from JavaScript. My questions are: 1) Do people just normally use hidden fields to store possible information to fill the drop downs? 2) any suggestions? You could use ajax to request the information needed to load the second drop down. Once the user chooses their bank, then your JavaScript makes an ajax request to a PHP script that returns the clients list. You use this to populate the second drop down. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This part works. You can see that page here:

/form
a href='showcrew.php'Show crew manifest/a
centerimg src=enterprise.jpg alt=Enterprise / /center

This is the one table in the database:
mysql describe crew_manifest;
++-+--+-+-+---+
| Field | Type | Null | Key | Default | Extra |
++-+--+-+-+---+
| first_name | varchar(20) | YES | | NULL | |

++-+--+-+-+---+
6 rows in set (0.06 sec)
and this is the corresponding php page that inputs the info:
?php
$first_name = $_POST['firstname'];
$last_name = $_POST['lastname'];
$rank = $_POST['rank'];
$division = $_POST['division'];
$ship = $_POST['ship'];
$email = $_POST['email'];
$dbc = mysqli_connect('127.0.0.1','admin','secret','trek_db')
or die('Error connecting to MySQL database');
$query = INSERT INTO crew_manifest VALUES
('$first_name','$last_name','$rank','$division','$ship','$email');
$result = mysqli_query($dbc,$query)
or die('Error querying database');
echo crew member added;
mysqli_close($dbc);
?
But the page that reads the info is the problem:
html

?php
$dbc = mysqli_conect('127.0.0.1','admin','secret','trek_db')
or die ('Could not connect to database');
$query = SELECT * FROM crew_manifest;
$result = mysqli_query($dbc,$query);
while ($row = mysqli_fetch_array($result)) {
$first_name = $row['first_name'];
$last_name = $row['last_name'];
$rank = $row['rank'];
$division = $row['division'];
$ship = $row['ship'];
$email = $row['email'];
echo $rank . 'br /';
}
mysqli_close($dbc);
?
/font
/html
What I'd like to find out is why the while loop does not display info
from the database? The page does show up, but not any info from the
db.
Thanks in advance.

There is a point: if you are unfamiliar with code, wading through screens and screens of a function to find things like block beginning/ends makes for difficult time finding places where changes need to be made. I *never* have huge numbers of lines between a block beginning and end. Even if I did my IDE can quickly find the other end of the block for me. E.g. TextWrangler does this easily enough: just double-click immediately after an opening brace, and everything is highlighted to the closing brace. - all those functions should be arranged in alphabetical order within their containing file - having them in a random sequence makes it difficult to find the one you want. Also correct; this is a key point in making sure your scripts are maintainable. Ah-ha! So someone agrees with me on that point after all. +1 - when browsing through the code you have to keep jumping to another function, and then returning to where you came from. I don't know about you, but I would rather use the scroll wheel on my mouse than keep jumping from one position in the file to another. May I suggest an editor/IDE that lets you navigate to functions directly, then? I am *NOT* going to change my IDE just to suit *YOUR* preferences. TW provided a popup list of your functions. It still helps to have them in alpha order though, for ease of navigation in the popup list. [snip arguments] I write functions to do specific things. E.g. I have a function (actually in JavaScript) called switchTab() which switches from one user view to another. It's just over 200 lines long and is mostly a giant case statement - and it's already loaded with function calls. I suppose I could break it up into five separate functions, more or less one for each case value, but then I'd have lots of unimportant local variables to pass around as argument values, and, what's worse, lots of unimportant functions cluttering the place up. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Parse errors
After recently omitting a semicolon from the end of a statement, and having the result be a JavaScript error in an odd place, I'm trying to pin down just what PHP does with such errors. I made a small test script to run at CLI, which does some echoes and then, after that, I miss out a semicolon. On the command line, all I get is the parse error message with line number. The script where I'd left the semicolon out of my production code is reached via AJAX, and sends some results back. It consists of a number of functions, then the main code appears, starting with two requires. The first such included file has some functions, puts out a header and does an echo, and calls set_error_handler. It's in the second included file that the semicolon is missed off (inside yet another function). I would have expected that the results sent back would just consist of the Parse error: message, but for some reason the echo done in the first included file shows up as well (this is important as it frames the parse error message for me). Is this the expected behaviour? The doc for set_error_handler says you can't use it to recover from E_PARSE and the like, and the function I supply to it doesn't appear to be called. I was just surprised that the initial echo statement's output made it back to the JavaScript side. (I obviously don't expect to have parse errors show up in production, but having them nicely visible and logged during testing is useful) -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

A superglobal is predefined at run-time by the parser,

_SESSION, _COOKIE), whereas a global can be defined at any time, and
is available to the current instance. All superglobals are globals,

Now I'm confused.
My understanding is that all variables defined within the main script are
accessible within the main script because they are all within scope by
definition.
Additionally, main script variables are not accessible out of scope (such as
in a function) unless one uses $GLOBALS to retrieve those values.
In the following, $x is a global but not a super-global (AFAIK).

[PHP] Variable number of arguments problem
I have a function defined thus:
function my_func ($arg1, $arg2, $arg3, $arg4, $arg5, $arg6)
{
// code here
}
I call this with variously the first three arguments only, or all six, taking
care that if I call it with fewer arguments then I don't try to acces $arg4,
$arg5, or $arg6 (which is passed by reference, as is $arg1).
On my first attempt to execute this, I'm getting:
Missing argument 4 for my_func(), called in /path/to/source/file1.php at line
556 and defined
in /path/to/source/file2.php at line 3
Is this because $arg6 is passed by reference? There is some reference to this
in the docs and the user notes but it's a little unclear. Or is there another
reason?
Thanks,

Re: Re: Re: [PHP] What's Your Favorite Design Pattern?
On 07 Feb 2012 at 22:31, Paul M Foster pa...@quillandmouse.com wrote: Design Patterns are Way Nifty Kewl patterns of code which are supposed to facilitate certain types of operations. (Was that sarcasm you detected? Yes it was.) For example, the Singleton pattern. Let's say you had a configuration class that held the configuration values for your application, and you wanted to make sure there was only one object of that class instantiated, no matter how many times it was called in your code. You'd arrange the code and call the class in a certain way to ensure that only one object of that class resulted. To make your configuration class a singleton, you'd probably make the class have a *private* constructor (so no outside routine could call it), and then provide a method called get_instance() which tested for the existence of an object of that class. If such an instance was found, someone calling configuration::get_instance() would simply get the existing object returned to them. Otherwise, configuration::get_instance() would instantiate the class and then return the new object to the caller. As you can see, that's a peculiar way of setting up your code for a specific purpose. Other design patterns do other things and dictate setting up things in other ways. The definitive work on this (and where it first gained the most publicity) is a book called Design Patterns by four authors (Gamma, Helm, Johnson and Vlissides). It essentially contains a chapter about each (known at the time) design pattern and some pseudocode about how it might be constructed. I imagine the authors looked at a lot of code and discovered that programmers were coming up with code that, in each case was remarkably similar for solving certain types of programming problems. So they codified what that found and wrote a book about it. I have the book on my shelf, and it's decent technology, but you could spend your whole career and never use any of it, and get along just fine. Mmmm. Well, at this point I feel underwhelmed - but its entirely possible that I'm missing something profound [1]. After looking at some of the reviews of the book you mention on Amazon, I might be inclined to get a simpler intro. [1] In June 1982 (or was it '83?) I visited PARC with a small group from SLAC.

Code gets read and modified a lot more than it gets written, and all those tricks just trip up more junior teammates--and often even myself. :) David Agreed, in fact, I decided to create a new style naming convention where _ref is always suffixed to variable names that are references, along with doing the unset, just in case. This goes to show that references can be a recipe for subtle bugs to creep in, so best to isolate them as much as possible to their own convention. If the convention is followed, it should eliminate the possibility of this bug, even if the unset is left out. Tim
[PHP] Strange foreach reference issue
Hello,
This sure looks like a bug, but maybe there's some subtlety going on
that I don't understand, so I would appreciate some insight. After much
debugging, I tracked down a bug in my code to this test program. My PHP
version is 5.3.3, running under Fedora Linux.
?php
$row_list = array(
array(
'Title' = 'Title #1',
),
array(
'Title' = 'Title #2',
),
array(
'Title' = 'Title #3',
) );
printRows at start: . print_r($row_list, true);
foreach ($row_list as $idx = $row) {
print Title A $idx: {$row['Title']}\n;
}
printRows are now: . print_r($row_list, true);
foreach ($row_list as $idx = $row) {
print Title B $idx: {$row['Title']}\n;
}
?
When you run the program, it gives the following output:
--
Rows at start: Array
(
[0] = Array
(
[Title] = Title #1
)
[1] = Array
(
[Title] = Title #2
)
[2] = Array
(
[Title] = Title #3
)
)
Title A 0: Title #1
Title A 1: Title #2
Title A 2: Title #3
Rows are now: Array
(
[0] = Array
(
[Title] = Title #1
)
[1] = Array
(
[Title] = Title #2
)
[2] = Array
(
[Title] = Title #3
)
)
Title B 0: Title #1
Title B 1: Title #2
Title B 2: Title #2
--
Note that the second foreach repeats the second row, even though the
index is correct and the print_r shows things as correct.
Now, if you change the name of the reference variable from '$row' to
'$rowx' (for example), things will work. So clearly there's some issue
with $row being previously used as a reference that's contaminating
the subsequent use of $row in the foreach. If there's some logic to
this, it's escaping me.
Any insight on this would be appreciated.
Regards,
Tim Behrendsen

When you use an ampersand on the variable, that creates a reference to
the array elements, allowing you to potentially change the array
elements themselves (which I'm not doing here).
http://www.php.net/manual/en/control-structures.foreach.php
I do notice in the manual that it says, Reference of a $value and the
last array element remain even after the foreach loop. It is recommended
to destroy it by unset(). But that doesn't really explain why it
contaminates the next foreach loop in such an odd way. You would think
that the $row in the second loop would be assigned a non-reference value.

Well, it typically can, or at least can make a guess at it. The problem is that it's not something you can rely on across different OSes, as some handle it differently, or less reliably, or not at all. Basically, the result is non-deterministic. It's for this reason that, as of 5.4, PHP won't even ask the OS but will always return UTC (and complain a bit) if something else hasn't been set. This way, you at least have a chance of consistent results. If you're only supporting OS X, you can have your script that generates the Apache config file retrieve the system time zone, and then use that value in the php_value setting. If the script is in PHP, you can do this: $timeZone = `/usr/sbin/systemsetup -gettimezone`; Which just calls the systemsetup command line utility (basically, a CLI front-end to the settings controlled via System Preferences). Here's what that call returns when run on the command line on my system: H012316WHPV:~ rewilliams$ systemsetup -gettimezone Time Zone: America/Phoenix That is a very helpful hint - thanks.

However, php scripts are not long-running programs in general, unlike the apache server itself, for example, and certainly if the php scripts are running under apache, they will be time- and space-limited by whatever is set in the php.ini file. If these little scripts are merely responding to AJAX requests, they should be really short-lived. At present these scripts generally are short-lived, but with some notable exceptions. Hence my exploration of whether I could use websockets instead. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I have a clear idea about *that*. I want to figure out if it's possible to use web sockets with a small server written in PHP to replace my current structure of ajax + apache + processes (which I suppose it forks). I see these benefits: 1) possible benefit - presumably when an ajax request arrives, a new process is started and so PHP has to be loaded and initialised each time. But perhaps this is in some way optimised so the PHP process is left running and apache then just tells it to read/execute a new script. 2) Definite benefit - when a browser makes an ajax request to run a script, it gets no information back until the script completes. Then it gets all of it. I have a couple of unsatisfactory workarounds for that in my existing structure. Websockets appears to offer a way for the browser to receive timely information. 3) understand design patterns I don't know what this means. What your asking is practically impossible in any programming language akin to 'how to un-import packages in Java' or 'how to un-using namespace in C#'. If you don't want to use it, don't include it ;) I do want to use it but would like to be able to replace it with a newer version. If there is no way to do this then that is a data point. And here's another question. Can a child forked by pcntl_fork() use a socket that the parent obtained? Reading the socket stuff in the PHP doc, there are a number of user-supplied notes hinting this might be problematic. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
