I might be doing this backwards, but how do I extract the date from $week5

pass
echo displaydate($week5);
it echos February 14-18
$week0 = 2005-01-10;
$week1 = 2005-01-17;
$week2 = 2005-01-24;

$week5 = 2005-02-14;
$week6 = 2005-02-21;

`Doable´? Easy enough to learn how to do?

Hi John,
// convert your data to a timestamp:
$firstDayTs = strtotime($week5);
// add 4 days
$lastDayTs = $firstDayTs + (4 * 86400);
echo date('F', $firstDayTs) . ' ' . date('m', $firstDayTs) . '-' . date('m',
$lastDayTs);
Not tested. Maybe there's an easier way to do this.

Re: [PHP] Get name of extending class with static method call

public static function drive ()
{
return self::$className;
}
}
class Porsche extends Car
{
public static $className = __CLASS__;
}
Porche::drive(); // Should return Porche
Hi Daniel,
thanks for the idea but it causes an error:
Fatal error: Cannot redeclare property static public Car::$className in
class Porsche
If I ommit the definition of $className in Car I get this error:
Fatal error: Access to undeclared static property: Car::$className
If I ommit the definition of $className in Porsche the return value is 'Car'
not 'Porsche'. Arrrgh!
Will keep on trying.

The only other solution that comes to mind is a little messy but it lets
you get away with no object. Instead of calling the method statically
you can use call_user_func_array() with the child class name as a
parameter. Then change the parent method to accept the child class name
as a parameter.
?php
function call_static_child() {
$drive_args = func_get_args();
/** assume that first parameter is child of class Car */
return call_user_func_array(array($drive_args[0], 'drive'),
$drive_args);
}
?
Hi Jason,
thanks for taking a look but there *must* be a way to achieve this without
passing any parameters around. Otherwise I could just do:
Porsche::drive('Porsche');

Torsten, I also found the following link to be helpful. Check out the
user notes from michael at digitalgnosis dot removethis dot com (he did
something similar to what I have already suggested, i.e. call_user_func)
http://www.php.net/manual/en/language.oop5.static.php
Hi Jason,
thanks for the link. It helped me to find out that this does work:
class Car {
function drive() {
echo 'pre';print_r(debug_backtrace());
}
}
class Porsche extends Car {
function drive() {
parent::drive();
}
}
By tunnelling the call through Porsche's own drive() method
debug_backtrace() will contain two traces, one of them with the correct
class name.
I tried using reflection but reflecting car by using __CLASS__ doesn't
give any information about the classes that extend it. So this doesn't work
either.
Rory's proposed way of reading in the file contents and preg_matching the
method name works, but it's very, very ugly, indeed! ;)
Isn't it somewhat ridiculous that there is no *easy* way in PHP5 to achieve
what I consider to be a pretty straightforward requirement?:
Get name of the class that invoked a static call of an inherited method
I would like to thank all of those that cared about my problem and tried to
find a solution by providing a wide variety of ideas. Thank you very much!!!
Do you think it would be wise to ask for help on php-dev?

What is the best way to access one class from another? What I have is a
couple of core classes that are loaded into instances at the start of
each page. I then load instances of page specific classes. How would I
access the already loaded instances of the core classes from inside one
of the page specific classes?
I tried a few things that didn't work. Is the only way to do this is to
load another instance of the core classes?
I'm finally trying to really get my hands around OOP, which has gone
very smooth up until this instance:). I'm using v4 not v5.
I'm looking for something like this:
class Lists {
function UserList() {
}
...
}
$coreLists = new Lists();
...
class Data {
function Entry() {
$users = $coreLists-UserList(); file://Accessing Lists Class
...
}
}
Hi Brent,
this is a case of variable scope:
http://de2.php.net/variables.scope
There are different ways to solve your problem:
1. Declare $coreLists global in your method:
function Entry() {
global $coreLists;
$users = $coreLists-UserList();
}
2. Access it via the superglobal $GLOBALS:
function Entry() {
$users = $GLOBALS['coreLists']-UserList();
}
3. Pass the variable it to the class constructor and assign it to a class
property:
var $coreLists;
function Data($coreLists) {
$this-coreLists = $coreLists;
}

you should not use session_register() with your PHP version anymore, so just
delete the first of the upper two lines.

Thanks so much to all an sorry for my bad language
I guess you'll first have to delete all files in the directory. Try this
function:
/**
* Recursively clear a local directory
*
* @param string $sourceDirdirectory to delete
* @param integer $leveldirectory level (to avoid deleting the
root dir)
*/
function clearDirectory($sourceDir, $level = 0)
{
// proceed if source directory exists
if (is_dir($sourceDir))
{
// read dir contents
if ($handle = opendir($sourceDir))
{
/* This is the correct way to loop over the
directory. */
while(false !== ($dirItem = readdir($handle)))
{
if ($dirItem != '.' $dirItem !=
'..')
{
// directory
if (is_dir($sourceDir . '/'
. $dirItem))
{
clearDirectory($sourceDir . '/' . $dirItem, $level + 1);
}
// file
elseif (file_exists($sourceDir
. '/' . $dirItem))
{
unlink($sourceDir .
'/' . $dirItem);
}
}
}
// remove directory if it's not the root one
if ($level 0)
{
rmdir($sourceDir);
}
}
closedir($handle);
}
}
It will delete all direcotries and files *inside* the specified directory.
So the directory itself will not be deleted.
Just call it like this (without trailing slash!!!):
clearDirectory('/path/to/directory'); // or on windows
clearDirectory('c:\path\to\directory');
Hope it works for you.

I have set chmod on linux chmod to 777 but i can delete folder only when is
empty.
What I do ?
Thanks to all and sorry for my bad language.
I guess you'll first have to delete all files in the directory. Try this
function:
/**
* Recursively clear a local directory
*
* @param string $sourceDirdirectory to delete
* @param integer $leveldirectory level (to avoid deleting the
root dir)
*/
function clearDirectory($sourceDir, $level = 0)
{
// proceed if source directory exists
if (is_dir($sourceDir))
{
// read dir contents
if ($handle = opendir($sourceDir))
{
/* This is the correct way to loop over the
directory. */
while(false !== ($dirItem = readdir($handle)))
{
if ($dirItem != '.' $dirItem !=
'..')
{
// directory
if (is_dir($sourceDir . '/'
. $dirItem))
{
clearDirectory($sourceDir . '/' . $dirItem, $level + 1);
}
// file
elseif (file_exists($sourceDir
. '/' . $dirItem))
{
unlink($sourceDir .
'/' . $dirItem);
}
}
}
// remove directory if it's not the root one
if ($level 0)
{
rmdir($sourceDir);
}
}
closedir($handle);
}
}
It will delete all direcotries and files *inside* the specified directory.
So the directory itself will not be deleted.
Just call it like this (without trailing shlash!!!):
clearDirectory('/path/to/directory');
Hope it works for you.

Hi Dennis, see below

Please CC me

I am designing my own 'usr' class that takes care of logins. I need
to know the following to finish it.
---
A/ Does anybody use sessions for users who are not logged into the site,
and why?
This might make sense when you have a protected area on your web site.
Having the session run all the time would allow the user to naviagte the
whole site *after* login without losing his authentication. When he is
logged in, just store some kind of value or object in the session. On the
protected pages check for this value. If it's not in the session redirect to
a login page.
B/ If a user goes from unlogged in, unidentified user to a logged in,
identified user, is the first session canceled and new session started?
You can control this yourself - usually you don't have to start a new
session after login. But applying session_regenerate_id() adds a bit of
security because it changes the session id (which might have been public
before login).
See:
http://de3.php.net/manual/en/function.session-regenerate-id.php
C/ (The reverse), if a user goes from logged in, identified user to a
unlogged in, unidentified user, is the first session canceled and new
session started?
Use session_destroy() and redirect to the start/login page with a clean:
header('location: http://www.yoursite.com'); exit;
This will start a new session. You might also need to unset a cookie before
session_destroy() if you are using cookies.
D/ How is it possible, using PHP4+ sessions, to cancel a session a page is
opened with, and starting a new session?
Again, use a header redirect.
thanks all of you. I **LOVE** using this PHP 'thang' :-)

[PHP] Re: trying to do too much with functions?
Justin French [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
I have a few functions with way too many parameters in them, or
functions which have a non-obvious order of parameters which I
constantly have to refer to as I'm working. Since I'm using PHP as my
templating language (none smarty here!) as well as the programming
language. So I've been looking for some alternatives...
My main objectives:
1. have all parameters optional
2. have a mixed order for the paramaters
Other languages seem to do this well (Ruby, or perhaps RubyOnRails
seems good at it), but in PHP I can only see a few options... I'm
hoping someone might offer a few more ideas.
? $params = array('a'='123','b'='456'); echo doStuff($params); ?
?=doStuff(array('a'='123','b'='456'))?
?=doStuff('a=123','b=456')?
?=doStuff('a','123','b','456'); ?
?=doStuff(a='123' b='456')?
So, is that it? Have I thought of all possible options?
As you should have a fixed parameter order in your function you don't need
to pass the variable names in. So this is OK for up to three or four params:
doStuff('value1', 'value2', 'value3', 'value4');
If your function takes more than four parameters an associative array would
be the way to go (your first example). You might consider splitting it up
into several functions if it takes that many arguments.

Michael Gale [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hello, Morning .. at least it is where I am :) I have a small issue with sessions, at the moment I am using sessions on our web site and storing the session information in a db_table. It is working great. Right now I am only storing the users ID, name and role in the session data, but I would like to store other information as well. The problem is ... that if that person opens another browser window and connects to the site another session is not created. So if I try and store a variable that would be unique to each window it would get over written. Is this a configuration problem ? Thanks. An alternative might be omitting cookies and passing the session id around via GET/POST. This would solve your problem but might require some work to adapt your application.

Hi All,
I'm trying to generate a PHP page with 3 or 4 dropdown menus, each of one
dependant upon each other, that means:
#2 dropdown should change upon selecting something on dropdown #1, #3
should change based on the selection at #2 to finally submit the desired
query. Each dropdown menu should be generated from a mysql query based on
the previous selection.
I need to generate mysql queries based on each dropdown selection and the

figure out how to accomplish this.
Let me know if I make myself clear enough :)
Any help is very welcome!!
Thanks in advance,

Hi Francisco,
just point the form action to $_SERVER['PHP_SELF']. Then check the POST
value of the relevant dropdown and do your queries. For example:
// the value of your selects will probably be ids that's why you should cast
them to integers
if (isset($_POST['select1'])) {
$select1 = (int) $_POST['select1'];
// do your query for select2
}
if (isset($_POST['select2'])) {
$select2 = (int) $_POST['select2'];
// do your query for select3
}
if (isset($_POST['select3'])) {
$select3 = (int) $_POST['select3'];
// do your query for select3
}
if (isset($_POST['select4'])) {
$select4 = (int) $_POST['select4'];
// insert your data
}
I hope you get my point. For user convenience you could use JavaScript's
onChange() event to auto-submit the first three selects when the user has
selected a value.

almost be pathetic! I'm assuming the answers are in the php manual,
but I have not found the correct pages ... any pointers to manual

I'm writing my first class following an example I found on the web

object ... why is $db used instead of $db?
I'm used to a this.varName syntax from other languages ... I grasp
what is happening with $this-db, but I don't understand the literal
translation of - and would like help understanding.
Hi Kevin,
with PHP4 $db means the value is passed by reference. Otherwise a copy of
$db would be passed to the method. See here:
http://de2.php.net/references
With PHP5 variable assignments or passing variables to functions by
reference is standard.
$this-db is the PHP equal to this.varName. You access property db of the
current object. Methods are called this way:
$this-methodName()
Hope this clears things up a bit.

Aaron Todd [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I have developed a PHP based site that requires users to login. Their login information is kept in a MYSQL database. Currently, I am using an IF statement to verify what the user enters as their password with what is in the the database. If they are the same a session is created and they have access to the content of the site. As far as I know the password is being sent to the script in clear text and I was wondering what a good way would be to get this to be encrypted. My first thought is to encrypt the password in the database using crypt(). So if I view the table I will see the encrypted characters. Then change the IF statement to encrypt the password that the user enters and then just check if its the same as what is in the database. That sounds like the same as I am doing now only instead of checking a password that is a name, its checking the encrypted characters of the name. So it seems my idea would hide the real characters. Can anyone tell me if this is a bad idea. And maybe point me toward a good one. Thanks, Aaron Hi Aaron, encrypting passwords in the database is generally a good idea. You can use md5() as an alternative to crypt(). MySQL itself has an MD5 function you can directly use in your SQL statements.

Hi,
Thank you for your replies. I am using version 4.3.3 yet unset() doesn't
seem to work. To test this I have placed this line of code in my
footer.php
file that appears at the bottom of every page:
echo 'load_orderinfo() = '.load_orderinfo();

function load_orderinfo() {
global $_SESSION;
if (empty($_SESSION[orderinfo])) {
return false;
} else {
return $_SESSION[orderinfo];
}
}
Before the $_SESSION[orderinfo] is created the output in the footer
reads:
load_orderinfo() =
When it has been created it reads:
load_orderinfo() = Object;
On the complete_order.php page where I call the clear_orderinfo() function
it goes back to:
load_orderinfo() =
but it on any subsequent page the output returns to:
load_orderinfo() = Object;
But after calling the clear_orderinfo() function surely the
$_SESSION[orderinfo] should have been destroyed. I hope this makes
sense!

[PHP] Re: Is this the right way to increase the amount of time session variables are dropped
Boot [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
Currently session variables are dropped in a shorter time period than I
would like when a user sits with a page open but idle.
My PHP.INI has session_gc_maxlifetime set to 1440.
If I want variables kept for two hours, is setting session_gc_maxlifetime
the correct setting to change (to 7200) ?
Thanks!
If you cannot edit your php.ini put this line at the top of all your
scripts:
ini_set('session.gc_maxlifetime', 7200);
You can also set this environment variable with a .htaccess file. Search the
archives to find out how the exact syntax is.

Re: [PHP] arrays() current() next() who to use
Vern [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Problem with that is it sorts according the results of the recordset range. For instance: It will show the user 1 trhough 10 sorted by miles then 20 - 30 sorted by miles, however, in 1 through 10 could have a range of 0 to 1000 miles and the next set will have 5 to 200 miles. What I need is to sort them all by miles first. The only way I know to do that is to do the way I set it up. So if I create an array, sort that array by the miles then use that array. However the array is different that the recordset and thus does not use LIMIT. What about this: SELECT * FROM table ORDER BY miles LIMIT 0, 10 Then pass the offset to your query function and exchange it with 0: SELECT * FROM table ORDER BY miles LIMIT $offset, 10 Of course you have to properly validate that $offset is an integer before using it in the query.

Can somebody point me in the direction to do this in php without frames

Hi Mick,
you have to append the file name of the bigger version to your links as a
parameter:
a href=?php= $_SERVER['PHP_SELF']; ??image=name_of_the_big_file1big
picture 1/a
a href=?php= $_SERVER['PHP_SELF']; ??image=name_of_the_big_file2big
picture 2/a
a href=?php= $_SERVER['PHP_SELF']; ??image=name_of_the_big_file3big
picture 3/a
Exchange name_of_the_big_file1/2/3 with the file names of the big image
versions. Then at the point where you want to show the big image include
this code:
?php
if (isset($_GET['image'])) {
$image = basename($_GET['image']);
echo 'img src=' . $image . ' border=0 alt=';
}
?
Of course you may have to alter the src attribute if your pictures are not
in the same directory.
Hope this helps, regards.

-{ Rene Brehmer }- [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
hi gang
I'm trying to find a simple way to determine if a given date/time is with
DST for a given locale at any point in time ... the point is basically to
convert date strings into accurate GMT timestamps for storage in the
database...
Like I've got date strings looking like:
Thursday, July 22, 2004 8:50:01 PM
July 22, 2004 6:42 PM
the strings are submitted through a form, together with a variable
determining the time zone these times are in. I just want to figure out if
the dates are with or without dst for that locale, at that given time, so
that I can properly convert them to GMT times ... but I have no clue how
to
do that ... haven't been able to find anything useful in the manual or the
PHP Cookbook ... the time zone is submitted negative of the actual value
...
so a time offset of -0700 is submitted as +7 and +0200 as -2 ... this is
simply to make the time conversion simpler...
these are extracts of the current time calculation codes, including some
debugging code for the time conversion:
?php
$date = $_POST['date'];
$tzone = $_POST['tzone'];
$timestamp = strtotime($date);
if ($tzone != 'none') {
$tdif = $tzone.' hours';
$timestamp = strtotime($tdif,$timestamp);
}
?
/* the following part is an extra of a larger table ... the formatting of
the time zone is merely for displaying purposes atm. The goal is to create
RFC2822 dates to be stored in the database alongside messages...
*/
tdWorkdate: ?php echo($date.' '.$tzone); ?br
Time difference: ?php
if ($tzone 0) {
$format = '-';
} else {
$format = '+';
}
if (abs($tzone) 9) {
$format .= '%u00';
} else {
$format .= '0%u00';
}
printf($format,abs($tzone)); ?br
Unix timestamp: ?php echo($timestamp); ?br
GMT date: ?php echo(date('D, d M Y H:i:s',$timestamp)); ?/td
if anyone has any ideas for determining whether DST is on or off, I'd
appreciate it. right now I have no clue how to do this the easiest...
TIA

Hi,
if you use the input type 'image' you have to check for name_x or name_y, so
in your case:
$_POST['submit'] = isset($_POST['submit']) ? $_POST['submit_x'] : '';
Whenever you have problems like this do a print_r($_POST) at the top of the
second page. This will show you all submitted values.

Re: [PHP] Local version works - production breaks
Robby, I just enabled log_errors locally. No errors (as I thought). Since I am hacking a previously written site, the problem seems to arise most when accessing his pre-built functions across pages. For instance, he uses a 'cards.php' to store all display functions -- showleft() -- showcentre() , as well as the connect() function. Hi Andre, make sure to use require_once for all includes. This will make sure to only include each file once and will trigger a fatal error if the file cannot be found because of a wrong path or whatever. Hope this helps, Torsten Roehr Since its a persistent connection -- he opens the db once, then performs various queries in it. However, since 'cards.php' has already been called once by a page that might require both showleft() and showcentre() -- it barfs and says that it cannot 'redeclare' the showleft() function that has already been declared?? That is really some weird -- particularly when it works so well (as expected) locally - and also since I'm not 'redeclaring' but calling it for use! I cannot fathom why the production site would give this error. Perhaps I need to do absolute paths for all headers? But it doesn't make sense that a function cannot be called many times -- declaring it once, yes, but calling its use?? If that were the case, then one might as well write it out longhand for each use, and forget the concept of 'functions'. I think I should look at the error logs for the site -- maybe they will clue me in where I should look.

Take a look here: http://pear.php.net/manual/en/package.http.http-download.intro.php Hope this helps, Torsten -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: Need Some Direction
Aaron Todd [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hello, I am trying to build up a members only site, but I need some direction. So far I have written a page that will let a user register for access. That script emails me their info so I can validate it, sends them a thankyou email and then sends the data to a temporary MySQL database table. In the email that I get I created two links. One will send the user an acceptance email and put their info in a final database table. The other will send the user a Deny email and will delete their info from the temporary database table. I have also created a login script that will ask for a username and password and verify it with the database. If its all correct then it will redirect you to a restricted page. The direction I need is how do I go about restricting access to the members only pages? I have been reading up on sessions, which I think will be a cool addition to this site, but I still havent found much on restrictin access without a username and password. Currently my login and registration pages are located in the root of the domain. The all the members only pages are in a directory called /members/. Can anyone give me some direction on how I should go about all this. Thanks, Aaron Hi Aaron, you might want to take a look at PEAR's LiveUser: http://pear.php.net/package/LiveUser Takes a bit of time to set up but should be exactly what you are looking for.

Re: [PHP] Need Some Direction
Aaron Todd [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] So far I have made this work. But now I have to ask...what about a pdf file? I cant add php code to it so what do I do. I need to be able to restrict the pdf so a user can only get to it during a current session. Thanks again for all the previous posts. You all directed me to a good place. My pdf files sliped my mind when I posted. I should have added this problem before. I hope it can still be done. Thanks, Aaron Hi Aaron, put your pdf file outside of the webroot our in a .htaccess protected directory. Then read in the file contents, set the appropriate headers and output the file contents to the browser - this should prompt a download window.

[PHP] Re: Usng Session Vaiable in WHERE Statement
Harlequin [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
Could someone please help me with my syntax here...?
$MembersDataQry = SELECT * FROM MembersData
WHERE UserID='$_SESSION['logname']';
I get an error on line 2 but can't seem to figure out what I've missed.
The variable echoes fine so I know there's a string in there.
To use array values within double quotes you have to put curly braces around
them:
$MembersDataQry = SELECT * FROM MembersData WHERE
UserID='{$_SESSION['logname']}';
Or concatenate the string:
$MembersDataQry = SELECT * FROM MembersData WHERE UserID=' .
$_SESSION['logname'] . ';
Remember to apply mysql_real_escape_string() on any values used within a
query.

Hi,
I'm trying to use PEAR's DB class with the new PHP 5 MySQLi support on
MySQL 4.1.3, using this example from the PEAR's docs (with my parameters
of course). I'm getting DB unknown error messages after the query. The
same query from the mysql client works fine, there are no connection
problems... anyone has tried PEAR with mysqli?.
Hi,
you should ask this on the PEAR general mailing list.
Regards, Torsten Roehr
?php
// Create a valid DB object named $db
// at the beginning of your program...
require_once 'DB.php';
$db = DB::connect('mysqli://prueba:[EMAIL PROTECTED]:3306/mibase');
if (DB::isError($db)) {
die($db-getMessage());
}
// Proceed with a query...
$res = $db-query('SELECT * FROM users');
// Always check that result is not an error
if (DB::isError($res)) {
die($res-getMessage());
}
?
result:
DB Error: unknown error

[PHP] Re: Embedding JavaScript into a PHP generated web page
Robert Frame [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi There, I have a web page with a form that is generated by PHP, and part of my design utilizes JavaScript to provide some error checking within the objects in the form. I have written the javascript in an html document, but I am having trouble blending the two together. I have tried sending the javascript within an echo statement, as well as using straight HTML/JavaScript code, but nothing seems to work. Can anyone offer some help or direct me to a solution?

[PHP] Re: JavaScript in PHP or PHP in JavaScript
Robb Kerr [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
Let me preface this by saying that I don't know JavaScript. I've got a
page
that is built by a long complicated JavaScript that I was able to hack
just
enough to function the way I wanted. There are some lines of code -- those
that define div positioning -- that need to be different depending upon
what it obtained from my database. I could build a simple PHP if/then
statement and embed the entire JavaScript with the lines changed. Or, I
could build a simple PHP if/then statement with only the lines of
JavaScript that need to be changed and embed it within the JavaScript.
which would be better?
JavaScript in PHP
?php
if (conditional) {
?
several lines of JavaScript
?php
}
?
PHP in JavaScript
script language=JavaScript
several lines of JavaScript
?php
if (conditional) {
echo 'lines of JavaScript';
} else {
echo 'other lines of JavaScript';
}
?
several lines of JavaScript
/script
Thanx,
Robb
Hi Rob,
maybe you can use the ternary operator syntax for the affected lines:
echo (conditional) ? 'lines of JavaScript'
: 'other lines of JavaScript';

Thanks for any help or at least a point in some direction Alan Hi Alan, I guess you'd have to read the second file into an array as well (line by line) and then *for each* entry from the arp list loop through all entries of the mac list and compare the values. Have you considered putting the data into two MySQL tables? This would make dealing with it much more comfortable.
