You asked for easier. In this way the data is assigned to a usable

actually use it with either mysql_fetch_array or mysql_fetch_row.
Here is your query;
$sql = SELECT first_name, last_name, book_author.ordinal
FROM author, book_author
WHERE book_author.bookID = $idIN book_author.authID = author.id
ORDER BY ordinal;
You need not declare another array, but do it this way instead;
if ($results = mysql_query($sql, $db)) {
while ( $row = mysql_fetch_array($results, MYSQL_ASSOC) ) {
echo $row['first_name'];
echo $row['last_name'];
Then I have to add some loopy thing to assign the values to the
$variables... a real pita since my variable do not lend themselves too
well to linear alterations ($varIn, $var2IN, $var3IN... etc... so $i=0
and $i++ arren't going to be too cooperative here... I guess I'd have to
change that to $var1IN... and then figure out how to do $var.$i.IN ... I
already tried, but don't seem to have it right
etcetera.

The lazy part I will agree with :)
Well, I shouldn't say it, but laziness is a characteristic of
intelligence: why do more than you have to when you can be doing
something else. Actually, I am anything but lazy, I spend innumerable
hours trying to understand what all this coding is about... searching
the web and rummaging (and I do mean rummaging) in all the lists and
posts ... but just going through 20 or 30 listings out of more than
20,000 is already taxing... much easier to ask on the list... if someone
can understand my fuzzy questions, they may find the grace and
generosity to take pity on the ignoramus... ;-)
And I enjoy the ribbing and the humour ... it's a really very nice list!

Re: [PHP] how to extract fields from associative array into different variables
you dont have an alternative. you will have to loop because mysql_fetch_* functions fetch only one row at a time. you can use variable variables to achieve the above result (you will not require this if u use list() or extract() functions) http://us.php.net/manual/en/language.variables.variable.php and if you cant do the job with arrays, and u need separate variables list would be an useful function as suggested earlier. you may also consider using http://in.php.net/manual/en/function.extract.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Any ideas, suggestions, Thanks!
I tried the following:

fwrite($f,$d);

The produces a file called 'klop' containing exactly one byte = 0xFF.

option value=2Monuments, Temples amp; Tombs/option

in the above code... or do I need to insert a series of value selected
fields for the values?

$categoriesIN_options = array(1 = 'Civilzation',
2 = 'Monuments, Temples amp;
Tombs',

$selected_clean = array();
// Check for passed values and validate

[PHP] difference between two times? Date_diff and DateTime::diff
Hello, My journey of learning PHP is going well, so i've decided to make a small program which works out the difference between two times and records the data in a text file. I've searched the PHP manual for functions which can help me out, and I discovered the function Date_diff ( http://uk3.php.net/manual/en/function.date-diff.php )and the class DateTime::diff ( http://uk3.php.net/manual/en/datetime.diff.php ) My question is, how on earth do I use these functions ? I really don't understand the manual documentation. I've just moved onto the subject of classes and so I'm fairly new to the concept, although I am following it well. If someone could explain to me how to use ether of these ( Date_diff and DateTime::diff ) I would be VERY grateful. Thank you so much!

As I remember, you either have to double slash or use the other slash.

or
//servername/sharename/folder/file.xml

I think 'servername\sharename\folder\file.xml' will work if you're
using single quotes around the string. The only slashes that would
need escaped are the first two since the first slash in '\\' escapes
the second.

In a .php page: case 1): if j put a link to any page without session, all is ok; case 2): if j put a link to .php page with session -- when j click the link, the link take place only after system() command execution end.

You can extract all the global space in the CScope method, it's quite

Thanks for the reply, I believe I have a fair understanding of
functions, and I have followed the example on the PHP manual page ( http://uk3.php.net/manual/en/function.date-diff.php

would it be like this for example:

Matt,
Do you understand how to use functions?
A function is defined like this:
function () {
//code goes here
}
You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1
$dtTime2
To use in a script, you need to first define the function, as per
the example:
?php
function GetDeltaTime($dtTime1, $dtTime2)
{
$nUXDate1 = strtotime($dtTime1-format(Y-m-d H:i:s));
$nUXDate2 = strtotime($dtTime2-format(Y-m-d H:i:s));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = . $nUXDelta/60/60; // sec - hour
$nPos = strpos($strDeltaTime, .);
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;
}
?
Then you need to call the function like this:
?php
GetDeltaTime(time1-goes-here, time2-goes-here)
?
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up
on functions: http://www.w3schools.com/php/php_functions.asp
Hope this helps - I'm probably in a similar situation to you and
have been dabbling with PHP for a few years just as a hobby but

RE: [PHP] difference between two times? Date_diff and DateTime::diff
Hi Matthew,
A quick note on the DateTime::diff() method - it's only available as from
PHP 5.3, which is currently in release candidate stage, meaning unless you
have your own server running PHP, it won't be available to use (hopefully -
I would be sceptical of any webhost which rolls out RCs on production
servers).
If you need to know what version of PHP you're running, use:
phpversion() or phpinfo()

Is there a way to obtain case 1) behaviour also in case 2) ? I may have interpreted your problem incorrectly, but I think your problem is due to the session data not being saved until the script has finished running, including the system call. To get around this you can save and close the session before calling system using the session_write_close [1] function.

Why do you need them in separate variables? Can't you use them using
array syntax elsewhere in your code?
Basically, I don't know how else to handle inserting and updating random
number of authors. Each book in the db may have up to 5 authors. I
imagine there is a simpler way to do it; I just don't have the knowledge
or experience or the time to learn another way. I'd be happy to have you
look at the code and hear some feedback. It's probably a miracle that
the site is working... ;-)

Why not just use $author[0]['first_name'] instead of $first_nameIN (and

I probably should have explained in greater detail: there are up to 5
authors for each book in the db and the insert and update fields in the
form input needs the different variables as each author is treated
separately. I'm not sure if there is another way to do it.

Re: [PHP] how to extract fields from associative array into different variables
I'm going to assume that your table is setup to have the rows BookID and
AuthorName, adjust accordinging:
function makeInsertQuery(array $authors, $bookId) {
$sql = INSERT INTO book_authors (BookID, AuthorName) VALUES ('$bookId', ';
foreach($authors as $author) {
$author = mysql_real_escape_string($author);
}
if(!ctype_digit($bookId)) {
return false;
}
$sql .= implode(', '$bookid'), (', $authors); // Eric Foo', '123'), ('John
Bar', '123'), ('Ricky Bam', '123'), (';
$sql = substr($sql, 0, -4);
return $sql;

The difficulty, it seems to me, is not in retrieving the rows, but
rather how to pass the row data to the variables. And since the number
of rows is variable, I believe that the only way to assign the
variables
is by use of a loop? I think I'm beating my head against the wall for
nothing... :-(
[/snip]
You asked for easier. In this way the data is assigned to a usable
variable right out of the gate and that is an array variable. You can
actually use it with either mysql_fetch_array or mysql_fetch_row.
Here is your query;
$sql = SELECT first_name, last_name, book_author.ordinal
FROM author, book_author
WHERE book_author.bookID = $idIN book_author.authID =
author.id
ORDER BY ordinal;
You need not declare another array, but do it this way instead;
if ($results = mysql_query($sql, $db)) {
while ( $row = mysql_fetch_array($results, MYSQL_ASSOC) ) {
echo $row['first_name'];
echo $row['last_name'];
Then I have to add some loopy thing to assign the values to the
$variables... a real pita since my variable do not lend themselves too
well to linear alterations ($varIn, $var2IN, $var3IN... etc... so $i=0
and $i++ arren't going to be too cooperative here... I guess I'd have to
change that to $var1IN... and then figure out how to do $var.$i.IN ... I
already tried, but don't seem to have it right
etcetera.
}
}
The lazy part I will agree with :)
Well, I shouldn't say it, but laziness is a characteristic of
intelligence: why do more than you have to when you can be doing
something else. Actually, I am anything but lazy, I spend innumerable
hours trying to understand what all this coding is about... searching
the web and rummaging (and I do mean rummaging) in all the lists and
posts ... but just going through 20 or 30 listings out of more than
20,000 is already taxing... much easier to ask on the list... if someone
can understand my fuzzy questions, they may find the grace and
generosity to take pity on the ignoramus... ;-)

Re: [PHP] difference between two times? Date_diff and DateTime::diff
Hi Dajve and Tom,
Thanks again, I totally didn't realise that this function is yet to be

Do you understand how to use functions?
A function is defined like this:
function () {
//code goes here
}
You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1
$dtTime2
To use in a script, you need to first define the function, as per
the example:
?php
function GetDeltaTime($dtTime1, $dtTime2)
{
$nUXDate1 = strtotime($dtTime1-format(Y-m-d H:i:s));
$nUXDate2 = strtotime($dtTime2-format(Y-m-d H:i:s));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = . $nUXDelta/60/60; // sec - hour
$nPos = strpos($strDeltaTime, .);
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;
}
?
Then you need to call the function like this:
?php
GetDeltaTime(time1-goes-here, time2-goes-here)
?
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up
on functions: http://www.w3schools.com/php/php_functions.asp
Hope this helps - I'm probably in a similar situation to you and

Hello,
My journey of learning PHP is going well, so i've decided to make a
small program which works out the difference between two times and
records the data in a text file.
I've searched the PHP manual for functions which can help me out,
and I discovered the function Date_diff (
http://uk3.php.net/manual/en/function.date-diff.php
)and the class DateTime::diff (
http://uk3.php.net/manual/en/datetime.diff.php
)
My question is, how on earth do I use these functions ? I really
don't understand the manual documentation.
I've just moved onto the subject of classes and so I'm fairly new to
the concept, although I am following it well.
If someone could explain to me how to use ether of these ( Date_diff
and DateTime::diff ) I would be VERY grateful.
Thank you so much!

Re: [PHP] Link to .php page with session
On Tue, Jun 16, 2009 at 08:23, Stuartstut...@gmail.com wrote: I may have interpreted your problem incorrectly, but I think your problem is due to the session data not being saved until the script has finished running, including the system call. To get around this you can save and close the session before calling system using the session_write_close [1] function. Note that after calling that you won't be able to make any other changes to the session data in that request. Stuart (plugwho I saw yesterday is listed as a Twitter API developer in the official docs, by the way ;-P /plug) hit the nail right on the head there, Santel. Until the system() function receives a return response from the spawned application, it'll hold up the rest of the page execution. There are, among others, two ways you could easily handle this: 1.) Write a wrapper shellscript, for which I'll give a simple example below. 2.) Use the proc_open()[1] or popen()[2] functions in PHP. To use a wrapper script is simple, and here's one way of doing it: ?php // yourfile.php // Your existing code goes here, replacing the system() call with: system(./convert.sh file.wmv); // and then continue with your code. ? #!/bin/bash # convert.sh # Remember to chmod this to 0755 or similar, allowing it to execute. nohup /usr/bin/ffmpeg -re -i $1 -f flv -an -sameq - /dev/null 21 # End of shellscript. This requires only that you pass the name of the file to be encoded, and then sends all of the output from ffmpeg to /dev/null (including STDERR) and detaches the process from the shell (spawning a poor-man's daemon ;-P).

I thought about creating a separate form within the original form page that could calculate the cost, and process it to itself, I suppose I would need to create a session so all the information in the first form is not wiped out. Is there an easier way to do this or is there a way to create this calculator that changes upon the input instead of clicking a calculate button?

Hi,
This is a quick function that works using unix time stamps. Its a bit quick
and messy but
works ok. Take a look at the manual page for the strtotime() function to get a
better idea
of what it can handle.
?
$Date1_UnixTimeStamp=strtotime(10:10:45);
$Date2_UnixTimeStamp=strtotime(12:45:03);
print_r(DateDiff( $Date1_UnixTimeStamp, $Date2_UnixTimeStamp));
function DateDiff( $Date1_UnixTimeStamp, $Date2_UnixTimeStamp){
$return_difference = Array(

$amounts= Array(
Days = 60*60*24,
Hours = 60*60,
Minutes = 60
);
$difference = $Date2_UnixTimeStamp - $Date1_UnixTimeStamp;
if($difference = $amounts[Days]){
$return_difference[Days] = floor($difference /
$amounts[Days]);
$difference -= $return_difference[Days] * $amounts[Days];
}
if($difference = $amounts[Hours]){

Hi Tom,
Thanks for the reply, I believe I have a fair understanding of
functions, and I have followed the example on the PHP manual page (
http://uk3.php.net/manual/en/function.date-diff.php
), ideally I want to know how to use the class DateTime::diff, how
can I use the DateTime::diff to get the difference between two times/
dates ? I suppose then I'm after the syntax
would it be like this for example:
$DIfferenceInTime = DateTime::diff(10:00,12:32);
Thanks again for helping me out.

Matt,
Do you understand how to use functions?
A function is defined like this:
function () {
//code goes here
}
You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1
$dtTime2
To use in a script, you need to first define the function, as per
the example:
?php
function GetDeltaTime($dtTime1, $dtTime2)
{
$nUXDate1 = strtotime($dtTime1-format(Y-m-d H:i:s));
$nUXDate2 = strtotime($dtTime2-format(Y-m-d H:i:s));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = . $nUXDelta/60/60; // sec - hour
$nPos = strpos($strDeltaTime, .);
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;
}
?
Then you need to call the function like this:
?php
GetDeltaTime(time1-goes-here, time2-goes-here)
?
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up
on functions: http://www.w3schools.com/php/php_functions.asp
Hope this helps - I'm probably in a similar situation to you and

Re: [PHP] Form Process Question
My my, someone woke up on the wrong side of the bracket
Acutally, the silliness of the request has not been lost on me or the
client. And no, it is a simple 195 times number of people, which is usually
under 5, so, I understand your recent scratching of the head...
I was thinking/hoping there was some mechanism that would calculate the
amount without hitting the submit button, something like a OnExit command.
Something that I would not have to work around the validation feilds being
lost and without having to make up a couple of new files...

RE: [PHP] populate form input option dropdown box from existing data
Yeah, I used to write that way but found I and others in the team saved a
lot more time troubleshooting and extending the code when returning 6 months
later if it was more verbose. Horses for courses, I guess.
Also, the selected attribute should be selected='selected' to validate
correctly as xhtml. By the same token, looking back at my example, I notice

You can try like this,
$row = stored data;
and write the options like this
option value=id (id == $row ? selected : ) /option

Subject: [PHP] populate form input option dropdown box from existing
data
I am having difficulties figuring out how enter retrieved data into a
dropdown box for editing. Here's a snippet:
...snip
select name=categoriesIN[] multiple size=8
option value=1Civilization/option
option value=2Monuments, Temples amp; Tombs/option
option value=3Pharaohs and Queens/option... snip
As I understand it, I need to put an array ( $categoriesIN[] )
somewhere
in the above code... or do I need to insert a series of value
selected
fields for the values?
The closest thing to what I need, seems to be in this post:
http://www.hpfreaks.com/forums/index.php?topic=165215
But it doesn't appear too inviting... not sure if they ever got it to
work...
Hi,
Something like this should work for you
?php
// Set up initial values
// This could be hard-coded or brought in from DB or other source
$categoriesIN_options = array(1 = 'Civilzation',
2 = 'Monuments, Temples amp;
Tombs',
3 = 'Pharaohs and Queens',
);
// Create a holder for values posted if you want
// to repopulate the form on submission
$selected_clean = array();
// Check for passed values and validate
if (array_key_exists('categoriesIN',$_REQUEST)) {
// Prevents errors with the foreach
$passed_categoriesIN = (array)$_POST['categoriesIN'];
foreach ($passed_categoriesIN as $options_key) {
// If the value isn't in our pre-defined array, handle the error
if (!array_key_exists($options_key,$categoriesIN_options)) {
// Handle error
continue;
}
$selected_clean[] = $options_key;
}
}
?
[snip]
select name='categoriesIN' multiple size='8'
?php // Loop over the options set above
foreach ($categoriesIN_options as $key = $value) {
echo option value='{$key}';
// Repopulate with selected
if (in_array($key,$selected_clean)) {
echo selected='selected';
}
echo {$value}/option\n;
}
?
/select

Hi Dajve and Tom,
Thanks again, I totally didn't realise that this function is yet to be
implemented in the mainstream PHP,
So is there no function that exists in vanilla PHP that can take two
dates/times and supply the difference ?
If there isn't I do apologise, i've been talking to my friend who does
ASP.net and he said he was sure there is for PHP.

Hi Matthew,
A quick note on the DateTime::diff() method - it's only available as from
PHP 5.3, which is currently in release candidate stage, meaning unless you
have your own server running PHP, it won't be available to use (hopefully -
I would be sceptical of any webhost which rolls out RCs on production
servers).
If you need to know what version of PHP you're running, use:
phpversion() or phpinfo()

Hi Tom,
Thanks for the reply, I believe I have a fair understanding of
functions, and I have followed the example on the PHP manual page (
http://uk3.php.net/manual/en/function.date-diff.php
), ideally I want to know how to use the class DateTime::diff, how
can I use the DateTime::diff to get the difference between two times/
dates ? I suppose then I'm after the syntax
would it be like this for example:
$DIfferenceInTime = DateTime::diff(10:00,12:32);
Thanks again for helping me out.

Matt,
Do you understand how to use functions?
A function is defined like this:
function () {
//code goes here
}
You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1
$dtTime2
To use in a script, you need to first define the function, as per
the example:
?php
function GetDeltaTime($dtTime1, $dtTime2)
{
$nUXDate1 = strtotime($dtTime1-format(Y-m-d H:i:s));
$nUXDate2 = strtotime($dtTime2-format(Y-m-d H:i:s));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = . $nUXDelta/60/60; // sec - hour
$nPos = strpos($strDeltaTime, .);
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;
}
?
Then you need to call the function like this:
?php
GetDeltaTime(time1-goes-here, time2-goes-here)
?
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up
on functions: http://www.w3schools.com/php/php_functions.asp
Hope this helps - I'm probably in a similar situation to you and
have been dabbling with PHP for a few years just as a hobby but
thought I'd try and help out.
You'll learn a lot from reading this list as well.
Cheers and good luck,
Tom
2009/6/16 Matthew Croud m...@obviousdigital.com
Hello,
My journey of learning PHP is going well, so i've decided to make a
small program which works out the difference between two times and
records the data in a text file.
I've searched the PHP manual for functions which can help me out,
and I discovered the function Date_diff (
http://uk3.php.net/manual/en/function.date-diff.php
)and the class DateTime::diff (
http://uk3.php.net/manual/en/datetime.diff.php
)
My question is, how on earth do I use these functions ? I really
don't understand the manual documentation.
I've just moved onto the subject of classes and so I'm fairly new to
the concept, although I am following it well.
If someone could explain to me how to use ether of these ( Date_diff
and DateTime::diff ) I would be VERY grateful.
Thank you so much!

Here's the solution: HTML select name=categories option value=1Civilization/option option value=2Monuments, Temples amp; Tombs/option option value=3Pharaohs and Queens/option /select PHP $category = $_POST['categories']; The variable $category will contain 1, 2, or 3 after a post form submit. Try it. The reference/link you cite above is for a dynamic select control that incorporates javascript to populate the second select control. It's not a simple select.

Acutally, the silliness of the request has not been lost on me or the

I was thinking/hoping there was some mechanism that would calculate the

Something that I would not have to work around the validation feilds being

There is, it's called javascript ;-) and for this application it should
be very easy. Something like this (not tested), or a variation:
script type=text/javascript
function calculateTotal()

var qty = document.getElementById('qty').value;
var cost = document.getElementById('cost').value;
document.getElementById('total').value = (qty * cost);
}

Just to point something out here: based upon the information you
sent to the list, this question sounds ridiculous, because on the
surface, it sounds like, the class is $195, so how should I calculate
this as a total? ;-P
Sometimes, when doing a project, we forget that *we* know all of
the information, but those with whom we're trying to communicate do
not. What other figures would be calculated into this? Is there tax
levied in certain circumstances (like if they live in Pennsylvania)?
Is there an option for registering and paying for multiple
participants on a single order? Can they pay for more than one class
at once? Are prices meant to be pulled in real-time from a database
or other remote or dynamic source?
If all of the above questions are no, then it's even easier:
?php
$amount = 195;
setlocale(LC_MONETARY,'en_US');
echo money_format('%n',$amount);
?
If even one of the questions above is answered with a 'yes,' then
you'll want to consider the alternatives and weigh each option. Maybe
you'll want to use JavaScript, maybe you'll want to do server-side
processing --- maybe a combination of both (i.e. - AJAX) if you need
to pull from the database and want to present the information without
refreshing/reloading a page.

it downloads the file to them, and this works great:
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.

$size = filesize('../../store/files/'.$file_row['filename']);
header('Content-Length: '.$size);
readfile('../../store/files/'.$file_row['filename']);
So I have my DMG file. I've verified that it automounts and behaves
friendly. If you do a direct download, it mounts on the desktop
perfectly, and there's all the stuff inside.
However, when I complete a test purchase and download using the above
code, the DMG file downloads, but then it mounts; the contents are
copied into the Downloads folder; the image unmounts; and then
deletes. All the contents are delivered, but not in a desirable way.

I have been diligently studying all this and have just returned my

Now, I was happy to learn that it is simpler to populate the insert new

It looks to me like the best solution for the edit page is close to what
Yuri suggests.
Since the edit page is very similar to the insert new books page, I
merely need to populate the Select options box slightly differently.
This is the code to populate the insert page:
select name=categoriesIN[] multiple size=8

$sql = SELECT * FROM categories;
if ( ( $results = mysql_query($sql, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {

}
}
?

The problem nowis to find a way to add a conditional clause above that
will insert the option=selected in the output.
The input for this comes from:
// do categories
$sql = SELECT id, category FROM categories, book_categories
WHERE book_categories.bookID = $idIN
book_categories.categories_id = categories.id;;
if ( ( $results = mysql_query($sql, $db) ) !== false ) {

[PHP] Re: Issues with APC, cache corruption?
On Mon, Jun 15, 2009 at 9:42 AM, James McLeanjames.mcl...@gmail.com wrote: Hi All, Over the weekend I setup a test of APC intending to benchmark a Moodle installation with various APC settings to see how well I could get it to perform. I successfully installed Moodle 1.9 and 2.0 under Apache 2.2.3 (installed via apt on Ubuntu 9.04), and with PHP 5.2.9 compiled from source. I should note, that Ubuntu had an older version of PHP installed from apt with Suhosin hardened PHP built in. Moodle 2.0 required at least PHP 5.2.8, so I uninstalled the original PHP module before compiling and installing the 5.2.9. No issues there; PHP worked well and performance was (mostly) acceptable. Progressed onto installing APC, firstly by downloading the APC 3.1.2 source from PECL and following the usual 'phpize, configure, make, make install' process which worked as expected, stop and start Apache and APC was present in my phpinfo();. I started with the reccomended PHP config exept with error_display turned on and E_ALL | E_STRICT enabled, and also the reccomended APC config also. I copied the 'apc.php' from the source tree to my webroot and changed the password as suggested. The issue arose when I attempted to benchmark my Moodle install with 'ab' (I realise it only downloads the single page, but it's good enough for what I need for now though) and the result was no different to before I had installed APC. View the apc.php page, and the only page cached is apc.php itself.. Certainly not what I've witnessed in the past. Then what would happen was if I viewed my seperate info.php page containing simply the opening PHP tag and a single line with phpinfo(); in the file - the cache would appear to reset, and it would firstly not load the info.php into the cache, it would reset the counter on the apc.php file back to 0. Through all of this, there was no errors displayed on the screen and no errors listed in the Apache error log either. Increased the Apache log level up to Debug, and no related information was displayed. Moodle itself worked as expected with no errors, and on a seperate RHEL installation I have Moodle working with APC and it is caching all it's files as expected. At this point, I thought it may be an issue with the module I compiled myself. I backed up the module, and allowed PECL to install the module, it installed 3.0.19. Restarted Apache and verified the version was as PECL had built and installed. This had no effect, and yeilded the same behaviour. I'm stumped as to what the issue could be, however I did see this issue of APC not caching files on an installation of Red Hat Enterprise Linux in the past - however at the time we assumed it was an issue with the framework we were using and due to time constraints simply ran without APC and didn't investigate further. Has anyone seen this issue in the past and perhaps even rectified it? Any information would be appreciated. As I have not had a response to my question yet, is there anyone who may be able to shed some light on the issue? Last night I also tried some different configure options when building APC but with the same result.. Has anyone seen this behaviour before? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Yeah, view source doesn't show any selected words.

Yuri, I'm still wet behind the ears on this so I don't quite
understand what you mean by stored data ; and what does the id
(id==$row?selected:) mean?
I get the idea that this might be translated into something in the code
I have dreamed up - further down.
echo option value=, $row['id'], , $row['category'], /optionbr
/;
I suppose that I must add an if clause to insert the selected option for
the categories that are relevant...
Gentlemen,
I have been diligently studying all this and have just returned my
attention to the list, so I've read the replies/inputs and now comment:
BTW, I had some problems with the multiple statement - it does not take
any parameters; it must simply be stated multiple without quotes.
Now, I was happy to learn that it is simpler to populate the insert new
books page dynamically from the db. Much shorter neater.
It looks to me like the best solution for the edit page is close to what
Yuri suggests.
Since the edit page is very similar to the insert new books page, I
merely need to populate the Select options box slightly differently.
This is the code to populate the insert page:
select name=categoriesIN[] multiple size=8
?php
$sql = SELECT * FROM categories;
if ( ( $results = mysql_query($sql, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
echo option value=, $row['id'], , $row['category'],
/optionbr /;
}
}
?
/select
The problem nowis to find a way to add a conditional clause above that
will insert the option=selected in the output.
The input for this comes from:
// do categories
$sql = SELECT id, category FROM categories, book_categories
WHERE book_categories.bookID = $idIN
book_categories.categories_id = categories.id;;
if ( ( $results = mysql_query($sql, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
echo$row['id'], br /;
}
}
This may return any number of category ids so the problem is to figure
out a way to pass the ids from the above code to the right ids in the
first code above.
How what do I search to match the two ids?

I just cannot find a way to pass the selected fields to the options script.
Even if I add the selected to all the fields, they show up in the source
code but the fields are still not highlighted.
There has to be a way to get this right??? :'(

RE: [PHP] sloppiness stupidity
While ranting might be good for the psyche there are trained psychiatric professionals that will readily listen to your rants. The PHP mailing list is not the place to vent. In every large community there will be those with less experience than others, and yes, many inexperienced programmers that will do whatever it takes to get things working, even if that means copying and pasting code they don't understand. Instead of ranting, a more useful approach would be to create a post that properly informs a user on how to populate a multiple option select box and eventually rank higher than any incorrect postings. -Original Message- From: PJ [mailto:af.gour...@videotron.ca] Sent: Tuesday, June 16, 2009 8:44 PM To: php-general@lists.php.net Subject: [PHP] sloppiness stupidity I'm sorry, guys, but I am really getting po'd.

[PHP] Persistent data between two executions
Hey everyone, Long time reader, not such a long time poster :-P (though I have posted to the list occasionally in the past...) Anyway, I have a general question for the list. Basically, I need to maintain persistent objects between page refreshes. So, for example, if while running a PHP script the first time I create an instance of class foo, the next time the script is run (when the browser reloads the page) I can again access that same instance of foo. I know that there's no way to truly do that, since a script only runs while generating output for the browser, but my question is, in the group's opinion, what's the best way to mimic this sort of behavior using temporary storage? Should I be using temporary files? I can think of at least a couple ways to do it, but I'd like to get some opinions as to best practice techniques, which take both security and relative efficiency into account. I would want to make sure that data isn't shared between multiple concurrent sessions, which would be a bad thing for what I'm doing. my oh-so-limited knowledge of PHP is shining through, I think :) Thanks so much!

Re: [PHP] Persistent data between two executions
You can use $_SESSION to store the object, and serialize to convert to string and reverse http://ar2.php.net/manual/en/language.oop.serialization.php // file one.php require 'user.php'; $user = new User(); $_SESSION[ 'user' ] = serialize( $user ); // file two.php require 'user.php'; // the class needs to be declared $user = unserialize( $_SESSION[ 'user' ] ); I think this is the cleanest way to do, but no the best performant. If you need performance you can use the interface serializable http://ar2.php.net/manual/en/class.serializable.php If you need a resources (like a db connection) you can implement __sleep and __wakeup in your class http://ar2.php.net/manual/en/language.oop.magic-functions.php On Wed, Jun 17, 2009 at 12:11 AM, James Colannino ja...@colannino.orgwrote: Hey everyone, Long time reader, not such a long time poster :-P (though I have posted to the list occasionally in the past...)

This is VERY hypothetical, and mostly just to satisfy a curiosity, but let's assume that you write an application that supports a few hundred users, each of which happen to be logged on at the same time. Assuming that serialization/unserialization happens frequently in the application, how severely will that impact performance? I'd imagine quite a bit, since you're reading/writing a lot from disk, which is inherently slow. I suppose one interesting way to alleviate this problem on a per-machine basis would be to implement /tmp in a RAM disk, so that session data is effectively written to and read from memory instead of to and from the disk. I suppose the best solution would be to design things such that as little data as possible is serialized between page refreshes.
