PHP - How Do I Make Subdomains With Php

Good Day,

I'm using the following example script from http://php.net/manual/en/function.session-set-save-handler.php which I have placed in session-handler.php and is included at the top of my index.php file. I have multiple domain names for the same website, so naturally when a person logs into the site, I would like the session to be active across all the domains instead of them having to login again if say they go from mysite.com to mysite2.com.

session-handler.php
<?php

function open($save_path, $session_name)
{
  global $sess_save_path;

  $sess_save_path = $save_path;
  return(true);
}

function close()
{
  return(true);
}

function read($id)
{
  global $sess_save_path;

  $sess_file = "$sess_save_path/sess_$id";
  return (string) @file_get_contents($sess_file);
}

function write($id, $sess_data)
{
  global $sess_save_path;

  $sess_file = "$sess_save_path/sess_$id";
  if ($fp = @fopen($sess_file, "w")) {
    $return = fwrite($fp, $sess_data);
    fclose($fp);
    return $return;
  } else {
    return(false);
  }

}

function destroy($id)
{
  global $sess_save_path;

  $sess_file = "$sess_save_path/sess_$id";
  return(@unlink($sess_file));
}

function gc($maxlifetime)
{
  global $sess_save_path;

  foreach (glob("$sess_save_path/sess_*") as $filename) {
    if (filemtime($filename) + $maxlifetime < time()) {
      @unlink($filename);
    }
  }
  return true;
}

session_set_save_handler("open", "close", "read", "write", "destroy", "gc");

session_start();

?>

The script above doesn't appear to be throwing any errors, and I can login like normal but it doesn't seem to be saving the sessions at all. So I still have to login to each separate domain.

Any ideas?

Thanks,

I tried many ways but unable to pass sessions to virtual subdomains on my site..

I edited ihi.ini file and included
Code: [Select]
session.cookie_domain = .mydomain.com

I like to add that session is active on my main domain for www.mydomain.com only.. So how do I pass sessions for WWW to other subdomains ?

Thanks n Advance

Okay so my news script is set to view only 10 pieces of news. But I want it so that it starts a new page once I have more than 10 pieces of news.

Code: [Select]
<?php
require("functions.php");
include("dbconnect.php");

session_start();

head1();
body1();
new_temp();
sotw();
navbar();
     
$start = 0;
$display = 10;
$query = "SELECT * FROM news ORDER BY id DESC LIMIT $start, $display";
$result = mysql_query( $query );

if ($result) {
    while( $row = @mysql_fetch_array( $result, MYSQL_ASSOC ) ) {
        news_box( $row['news'], $row['title'], $row['user'], $row['date'], $row['id'] );
    }
    mysql_free_result($result);
} else {
    news_box( 'Could not retrieve news entries!', 'Error', 'Error', 'Error');
}
                   
footer();

mysql_close($link);
?>
I tried a few things but they failed....miserably.

Hi there, As the question says i tried several things but i can't work it out and my knowledge about php isn't that well.

$looponce = 1;
foreach ($this->info as $k => $v) {
if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) {
for ($i = 0; $i <= 0; $i++) {
$output[] = $this->display_errors('error_system_subject');
}
}
if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) {
$output[] = $this->display_errors('error_system_name');
$looponce++;
}
}

That is my loop that i check things in. What i'm more interested in is the name if statement.

If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s.

I'm looking for ways to remove the need for program errors and just change them to what is needed to run.

What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given.


above code $this->info = $formdata;

$formdata = array(
'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error.
'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'),
);


Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way?

Hi I just wanted to know how I can make this....

I want to write this in PHP, I dont know the best way to do this....

I am starting a software development company, Each time someone make a purchase of a software product I wan to include a cd key, I dont know how to include just one cd key... I want to place the cdkeys in a mysql db though which I know how to do, but just the fact of me taking only one cdkey out of it and it can't be used already... it has to go down the line how would I do this?

Thanks ahead of time

I have some code which i think is really inefficient especially as there will be more more conditions to be met.

I was thinking about using s switch but don't know if this is possible or if it's best leaving as it is.

Any ideas?

if($parts[($i-1)]=="forum") {
             //do some code
             } 
             else if($parts[($i-2)]=="forum") {
             //do code
             }
             else if (($parts[($i-1)]=="list-messages") && (isset($parts[($i+1)]))) {
             //do code
             }
             else {
                  // do some code
                }

So I'm trying to make a counter that counts how many times a record on mysql database has been viewed. Not a hit counter for a webpage. In other words I have a page that displays the info of that record from the mysql database and within that page I would like to display the amount of times it has been viewed. Would anyone know where I can begin or send me to a good tutorial?

Thanks

I am using this line of code my site

Code: [Select]
<?php echo (IMAGES_HEADER . "header_02.jpg" ?>
I have a page defining all my directories, on that page I have this

Code: [Select]
define('IMAGES_HEADER', DIR_IMAGES . 'header/');
instead of showing the image, all I am getting is "IMAGES_HEADERheader_02.jpg" where the image should be.

I am very new to PHP and trying to learn it, what in the world am I doing wrong??

Hi I had it on my old site but forgot what I put in the index.php file.

Basicly, I want something like this:

http://site.com/index.php?go=home

or:

http://site.com/index.php?home

Does anyone know what I put in the index.php file to specify link and where it redirects too?

Thank you.

ok I need to know how to do this

say I have variables.. like so

$a[] = 12345;
$a[] = 23456;
$a[] = 35424;

what do I have to do to get those variables to combine the value? and make that a variable?

so it would be like

$aCompiled = 12345,23456,35424,

puts them in a string then I can use the variable later on in the script..

Basically, All I want to do is save a .txt (doesn't have to be .txt) to my FTP and PHP simple echos it. The .txt is where a message is stored. But when I write the message my self like this:
Hello

This is a message.

- And then upload it to my FTP, PHP echos it like this "HelloThis is a message". Is there anyway for PHP to notice the 'white space'?

--OR--

If you know of a better way to make a message system, then also let me know

Thanks, Ollie!

Hi, We are currently making our thesis and part of it is make use of AT Hayes command, which i executed on hyper terminal.

first you need to configure the port where your modem is connected,
on my case its connected on com4, after configuring the ports you can now
execute at hayes commands on the hyper terminal.

i would like to ask if is it possible to execute at hayes commands using php
to send and recieve messages form cellphone and file it on database

I used this code




$limit = 120;

if (strlen($summary) > $limit)
$summary = substr($summary, 0, strrpos(substr($summary, 0, $limit), ' . . .'));



This code ok in English Language it counts letters fine
but it is not work fine if I insert Arabic text. It counts Arabic encoding characters.
