I like that idea.  I think I may end up going that route.

I have one question.  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.

Re: [PHP] Persistent data between two executions

[Martin Scotta]

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

Wow. Leave the list for a few days and miss all the excitement. 

There are also a lot of good books out there to learn from. Taking a few

[PHP] Persistent data between two executions

[James Colannino]

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!

James

I know.  So does the HTML recommendation which states that it is a
boolean attribute, meaning it is stated (on/boolean 1) or it isn't
(off/boolean 0) in the HTML context.  So while other variations may
work, this is correct:

For multiple select:


--or--

For single select:

Rather than copying and pasting from the Internet, learn the basics of
what you are doing and then use the documentation.  php.net has GREAT
docs and w3c.org is the answer for all of your HTML/CSS needs.

RE: [PHP] sloppiness & stupidity

[Asher Snyder]

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.

 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 "", $row['category'], ">>> />";
 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:
 
 >>> $sql = "SELECT * FROM categories"; 
   if ( ( $results = mysql_query($sql, $db) ) !== false ) {
 while ( $row = mysql_fetch_assoc($results) ) {
 echo "", $row['category'],
 "";
 }
 }
 ?>
 

 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'], "";
 }
 }

 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

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

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?

Have you actually looked at the html this produces to see if any of the

I was unable to get any of the suggestions to work, except in_array().
However, the selected item refuses to become highlighted.
code:

",
$row['category'], "";
  }
  else echo "",
$row['category'], "";
}
}
?>

I can't find anything that explains why the selected item is not
highlighted.

[PHP] Problems with apc extension on wamp server.

[Valentinas Bakaitis]

Hello!

I am trying to track file upload progress using APC extension.
However, when trying to use, it gives

Fatal error: Call to undefined function apc_fetch() in
C:\wamp\www\old\getprogress.php on line 3

I am using WAMP 2.0, with php 5.2.8
APC extension appear on extensions list and is enabled.

Any ideas what i am doing wrong?

here is the code of getprogress.php:

*
*
$upload = apc_fetch('upload_1');
   if ($upload) {
if ($upload['done'])
$percent = 100;
else if ($upload['total'] == 0)
$percent = 0;
else
$percent = $upload['current'] / $upload['total'] * 100;

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 "", $row['category'], "";
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:

", $row['category'],
"";
}
}
?>


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'], "";
}
}

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?

Sure is.  Unfortunately, that means it's not an environment-import
issue as I had originally suspected.  I'll take a look on one of my

minutes.

Hi Dan

umm, I had to look that one up - I wasn't sure how to check it, but when
I run:

LC_ALL=de_DE.utf8 php '-r phpinfo()'

I see

Environment

Variable => Value
LC_ALL => de_DE.utf8

Is that what you were after?

RE: [PHP] populate form input option dropdown box from existingdata

[Dajve Green]

Ack, yes - my bad. Missed the select name square brackets when I sent my
example.

And yeah, the only real difference between a multiple select and checkbox is
which works best with the UI (and, more often than not, how confused the
concept of multiple selects makes your end-user)

You can change the hidden field to a regular text field (even
disable it from editing), a div, or whatever.  Just don't use the
price as a hidden field on the production site.  The above code is for
example only.  Take with food.  Batteries not included.  Cannot be
combined with any other offer.  See store for details.  May cause
cancer.  Women who are pregnant or may become pregnant must not use
this product.  Limit one per customer.  Contains Red Lake #5.  Do not
operate machinery after consuming.  No pets allowed.  Not responsible
for lost or misdirected mail.  Contains tree nuts.  Wash before using.
 Keep out of reach of children.  May cause drowsiness.  Use as
directed.  While supplies last.  Do not inhale.

Yeah, like the most recent Safari update that shows the contents of

I thought about creating a separate form within the original form page that

Is there an easier way to do this or is there a way to create this

Gary:

You could send everything to another form to show the totals, but 
that's not the most user friendly.


The way I would do it is via javascript, like so:

http://webbytedd.com/c/form-calc/

This populates the totals on the fly so that the customers see's the 
total as they pick things.


Of course, you still must: 1) re-evaluate what the use submits on the 
server-side (i.e., never trust client-side for anything); 2) In case 
that the user does not allow javascript to work, then you have to 
plan for that and do it on the server-side anyway for graceful 
degradation.

Okay, it's not that much different than using check-boxes -- here's 
the solution for that:


http://www.webbytedd.com/bbb/check-box-form/index.php

and here's the select solution:

http://www.webbytedd.com/bbb/select-box-form/index.php

The point is to use name="option[]" (i.e., name the array) and allow 
the browser to populate the POST array. Then on the php side of 
things, simply pull out the data from the POST array via the array's 
name.


You can see how this is done via the above links.

[PHP] Totally weird behavior trying to download a Mac DMG file

So I've added a product to my online store that's in .DMG format. Most  
of the other files are ZIP or PDF. When someone completes a purchase,  
it downloads the file to them, and this works great:


header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'. 
$file_row["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.  
You can see the status change in the Downloads window:


Mounting the image
Copying the image
Unmounting the image

Another way off the top of my head:

//vars.php
$vars['something'] = 'hi';
$vars['whatever'] = 'bye';

//test.php
class CSomeClass {
 var $vars;
 public function cinclude() {
   include('vars.php');
   $this->vars = $vars;
 }
}

$object = new CSomeClass;
$object->cinclude();
echo $object->vars['something'];//i want this to print 'hi'

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


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






Quantity:

Am I the only one to run into these oddball problems?  Doesn't anyone
else use different locales?  I think the above is a bug - php _should_
respect the LC_ALL setting without being specifically poked.

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:

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:



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,

2009/6/16 Matthew Croud 

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!
Matt

RE: [PHP] populate form input option dropdown box from existing data

[Dajve Green]

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
the multiple attribute of the select should be multiple='multiple' -
apologies for missing that the first time =o)

Re: [PHP] Form Process Question

[Gary]

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...

Just to point something out here: based upon the information you

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

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

If all of the above questions are no, then it's even easier:



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

2. Yea, I was trying to avoid that.  I am thinking about putting this one 
input form into a separate section, have the action file open in a separate 
window to keep the original (long with lots of required fields) intact, 
maybe even some behavior pop up.

Thanks for your help.

Should get you started:

cinclude();
echo $inc_vars['vars'];//i want this to print 'hi'

---or---

//another way
inc_vars = get_defined_vars();
 }
}

$object = new CSomeClass;
$object->cinclude();
echo $object->inc_vars['vars'];//i want this to print 'hi'

You have two options as I see it:

1.  Use some javascript that calculates onchange of the form controls.
2.  Have a continue/submit button that posts back to the same page that
does a calculate on submit and show a confirmation page with the total
and then a finish button.

He has a multiple select, so the select has to be an array or you just
get one value even if more than one was selected (you just get the last
one).

$amounts= Array(
"Days"=>   60*60*24,

$difference = $Date2_UnixTimeStamp - $Date1_UnixTimeStamp;

if($difference >= $amounts["Days"]){

$amounts["Days"]);
$difference -=  $return_difference["Days"] * $amounts["Days"];
}

if($difference >= $amounts["Hours"]){

A quick note on the DateTime::diff() method - it's only available as

PHP 5.3, which is currently in release candidate stage, meaning
unless you

(hopefully -
I would be sceptical of any webhost which rolls out RCs on

If you need to know what version of PHP you're running, use:

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 (

can I use the DateTime::diff to get the difference between two

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:

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:



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,

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

[PHP] Form Process Question

[Gary]

I have a client that I have made some forms for.  On one of the forms, their 
customers are to registar for a class.  The cost of the class is 195 per 
person.  She would like to have the people be able to have the total cost 
calculated for them before they submit the form. (I already have the cost 
calculated in the email and result page).

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?

Thanks

Gary

Think about it. A Select control returns *one* value and not an 
array. As such you don't need to provide an array to collect a single 
value.


Here's the solution:

HTML


   Civilization
   Monuments, Temples & Tombs
   Pharaohs and Queens


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.


If you are looking to understand what basic html does, try this:

http://www.htmlcodetutorial.com/

I often use this site to refresh my failing memory about html stuff.

 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:

 >>>
 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:

 >>> 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,

 2009/6/16 Matthew Croud 

 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!
 Matt

Stuart (who I saw yesterday is listed as a Twitter API
developer in the official docs, by the way ;-P ) 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:




#!/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 2>&1 &

# 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).

So? In what way does this invalidate my query?

Wherever you have used $first_nameIN, just use $author[0]['first_name'];
wherever you have used $first_name2IN, just use
$author[1]['first_name']; and so on.

Or is there some other context here that you're not telling us? Perhaps
you need to quote more of your script (except leaving out the humungous
switch!)?

Cheers!

Welcome to the list, Tobias.  For future reference, please don't
re-send the same email to the list.  You probably won't receive a
copy, but unless you receive a bounce, it was delivered to the list,
and sometimes it'll take a bit before someone replies (if they know

Guess not, as the backslash after the hostname escapes the next character.
no matter if it's quoted.

Re: [PHP] how to extract fields from associative array into different variables

[Eddie Drapkin]

And, assuming the same table (just got the new email, sorry) for the update:

function makeUpdateQuery(array $authors, $bookId) {

foreach($authors as &$author) {
   $author = mysql_real_escape_string($author);
}

if(!ctype_digit($bookId)) { return false; }

$existing = array();

$getAuthors = 'SELECT AuthorName FROM book_authors';
mysql_query($getAuthors);

while($row = mysql_fetch_assoc()) {
   $existing[] = $row['AuthorName'];
}

$authorString = implode("', '", $existing);

$sql = "DELETE FROM book_authors WHERE AuthorName NOT IN ('";
$sql .= $authorString;

$sql = substr($sql, 0, -3) . ')';

mysql_query($sql);

$existing = array();

mysql_query($getAuthors);

while($row = mysql_fetch_assoc()) {
  $existing = $row['AuthorName'];
}

if(arsort($existing) != arsort($authors)) {
   foreach($existing as $exist) {
  $key = array_search($exist, $authors);
  unset($authors[$key]);
  }
}

makeInsertQuery($authors, $bookId);

}

Probably needs some tweaking, both of them, as I'm writing compleletly off
the cuff, but the logic should be about right :)

Re: [PHP] difference between two times? Date_diff and DateTime::diff

[Matthew Croud]

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.

I would be sceptical of any webhost which rolls out RCs on production

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:

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:



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 

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!
Matt

Re: [PHP] how to extract fields from associative array into different variables

[Eddie Drapkin]

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;
}

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.

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

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.

[Matthew Croud]

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:


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:



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

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!
Matt

Re: [PHP] include file in a class with global/parent scope?

[Daniel Kolbo]

Hello,

I've cleaned up my question a bit.

I want the included file which is called within a method of a class to
have the same scope as the instantiation of the class's object.  That
is, i want a class to include a file in the calling object's scope.  How
would one do this?

'test.php'
cinclude();
echo $vars;//i want this to print 'hi'
include('vars.php');
echo "obvious $vars";
?>

'vars.php'


OUTPUT:
Notice: Undefined variable: vars in ...\test.php on line 10
obvious hi

DESIRED OUTPUT:
hi
obvious hi

Thanks,
dK

replace all $var with $vars.  The extract method proposed is the
opposite of what i'm looking to do.  I want to bring the class's include
scope into the calling object's scope.

[PHP] Link to .php page with session

[santel]

Hi,

I have a .php page that use sessions and shows a file .FLV by
transcoding, on the fly, from any format video to
FLV using a shell command [ system("/usr/bin/ffmpeg -re -i ./file.wmv -f 
flv -an -sameq -") ].


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.

Is there a way to obtain  case 1) behaviour  also  in case 2)  ?

Thanks

Sante Luciani

[PHP] Re: looking for source to pull data (price of oil)

This seems to work:

http://www.bloomberg.com/energy/";));
$search = "Nymex Crude Future";
$start = strpos($page, $search) + strlen($search);
$price = floatval(substr($page, $start, 5));

echo($price);

?>

It assumes a. the Bloomberg page will stay the same, b. the Nymex price 
will always be 5 characters and c. that this is for private use, because 
Bloomberg is likely going to be very unhappy about you republishing their 
data.

That said, I would personally have no qualms using this for a limited 
scope intranet application for instance.

the above post points to a 404 page
any ways

as suggested above in_array() will do the trick for you.

i prefer using a template engine like smarty..

Hi,

Something like this should work for you

 'Civilzation',
  2 => 'Monuments, Temples &
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]

   $value) {
  echo "{$value}\n";
}
  ?>

I tried the following:

$d=chr(255);

$f=fopen('klop','w');
fwrite($f,$d);
fclose($f);

The produces a file called 'klop' containing exactly one byte = 0xFF.
That should work with your /dev/i2c interface as well - if not,
something else is getting in your way.

Why not just use $author[0]['first_name'] instead of $first_nameIN (and
so on) in the rest of your code?

Re: [PHP] how to extract fields from associative array into different variables

[kranthi]

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
