PHP - How To Organize A Dual Boot For Win 8 & Suse Linux? Filesytem Etc Etx

I am looking at making a photogallery system for an online community based site. I know that we need to have unique id's , photo names and albums.

What i am looking for is:

Would it be recommended to create a directory for each user once they are registerd?
How would you go about naming and sorting photogralleries?
How would you go about naming you photos?
How would you do it?

I was thinking about a uuid kind of code: ( from php.net)

  Code: [Select]
class UUID {
  public static function v3($namespace, $name) {
    if(!self::is_valid($namespace)) return false;

    // Get hexadecimal components of namespace
    $nhex = str_replace(array('-','{','}'), '', $namespace);

    // Binary Value
    $nstr = '';

    // Convert Namespace UUID to bits
    for($i = 0; $i < strlen($nhex); $i+=2) {
      $nstr .= chr(hexdec($nhex[$i].$nhex[$i+1]));
    }

    // Calculate hash value
    $hash = md5($nstr . $name);

    return sprintf('%08s-%04s-%04x-%04x-%12s',

      // 32 bits for "time_low"
      substr($hash, 0, 8),

      // 16 bits for "time_mid"
      substr($hash, 8, 4),

      // 16 bits for "time_hi_and_version",
      // four most significant bits holds version number 3
      (hexdec(substr($hash, 12, 4)) & 0x0fff) | 0x3000,

      // 16 bits, 8 bits for "clk_seq_hi_res",
      // 8 bits for "clk_seq_low",
      // two most significant bits holds zero and one for variant DCE1.1
      (hexdec(substr($hash, 16, 4)) & 0x3fff) | 0x8000,

      // 48 bits for "node"
      substr($hash, 20, 12)
    );
  }

  public static function v4() {
    return sprintf('%04x%04x-%04x-%04x-%04x-%04x%04x%04x',

      // 32 bits for "time_low"
      mt_rand(0, 0xffff), mt_rand(0, 0xffff),

      // 16 bits for "time_mid"
      mt_rand(0, 0xffff),

      // 16 bits for "time_hi_and_version",
      // four most significant bits holds version number 4
      mt_rand(0, 0x0fff) | 0x4000,

      // 16 bits, 8 bits for "clk_seq_hi_res",
      // 8 bits for "clk_seq_low",
      // two most significant bits holds zero and one for variant DCE1.1
      mt_rand(0, 0x3fff) | 0x8000,

      // 48 bits for "node"
      mt_rand(0, 0xffff), mt_rand(0, 0xffff), mt_rand(0, 0xffff)
    );
  }

  public static function v5($namespace, $name) {
    if(!self::is_valid($namespace)) return false;

    // Get hexadecimal components of namespace
    $nhex = str_replace(array('-','{','}'), '', $namespace);

    // Binary Value
    $nstr = '';

    // Convert Namespace UUID to bits
    for($i = 0; $i < strlen($nhex); $i+=2) {
      $nstr .= chr(hexdec($nhex[$i].$nhex[$i+1]));
    }

    // Calculate hash value
    $hash = sha1($nstr . $name);

    return sprintf('%08s-%04s-%04x-%04x-%12s',

      // 32 bits for "time_low"
      substr($hash, 0, 8),

      // 16 bits for "time_mid"
      substr($hash, 8, 4),

      // 16 bits for "time_hi_and_version",
      // four most significant bits holds version number 5
      (hexdec(substr($hash, 12, 4)) & 0x0fff) | 0x5000,

      // 16 bits, 8 bits for "clk_seq_hi_res",
      // 8 bits for "clk_seq_low",
      // two most significant bits holds zero and one for variant DCE1.1
      (hexdec(substr($hash, 16, 4)) & 0x3fff) | 0x8000,

      // 48 bits for "node"
      substr($hash, 20, 12)
    );
  }

  public static function is_valid($uuid) {
    return preg_match('/^\{?[0-9a-f]{8}\-?[0-9a-f]{4}\-?[0-9a-f]{4}\-?'.
                      '[0-9a-f]{4}\-?[0-9a-f]{12}\}?$/i', $uuid) === 1;
  }
}

// Usage
// Named-based UUID.

$v3uuid = UUID::v3('1546058f-5a25-4334-85ae-e68f2a44bbaf', 'SomeRandomString');
$v5uuid = UUID::v5('1546058f-5a25-4334-85ae-e68f2a44bbaf', 'SomeRandomString');

// Pseudo-random UUID

$v4uuid = UUID::v4();

I'm trying to organize MySQL output in an HTML table based on individual states. Here is how the static HTML is currently displayed: http://www.u-s-s-a.org/breeders.html. Here is my working document: http://www.u-s-s-a.org/breeders.php. As you can see on the HTML page, each db row is organized into individual states. I'm only concerned about the US states, and not the countries outside of the US.

Following is the code I've been working on (directoryoutput.php):

Code: [Select]
<?php
require '/home/srob/public_html/u-s-s-a.org/config.php';

$connect = mysql_connect ($dbhost, $dbuser, $dbpass) or die ('Cannot connect: '.mysql_error());
mysql_select_db ($dbname);

$query = "SELECT * FROM directory ORDER BY flockname";
$result = mysql_query($query) or die ('Error, query failed.');

echo "<tr><td width='33%' class='style9'><p align='left' class='style12'><a name='AR'></a>Arkansas</p></td><td width='34%'>&nbsp;</td><td width='33%' valign='top'><div  align='right'><a href='#TOP'><img src='returnTOTOPGRAPHIC/RETURNTOTOP.gif' width='113' height='21' border='0' align='absmiddle'></a></div></td></tr>";

$cnt = 0;

while($row = mysql_fetch_array($result, MYSQL_ASSOC)){

I'd appreciate any help on this code, including a more efficient way to parse out the MySQL db rows into 3 columns in the HTML table.

Thanks in advance!

Hello, I'm new to the forum and I'm looking for advice.

I use a bunch of classes in namespaces that are I'm attempting to organize for autoloading. In other words, a class called \Foo\Package\Class is loaded from the file at Foo\Package\Class.php. I'm using spl_autoload for this. (If I were on 5.2 I could be using underscore-delimited pseudo-namespaces just as well; the implementation detail isn't important)

Now, I want to have multiple separate apps that use a single common library. Each app also has some classes that are local to it. How should I solve the autoloading problem?

I thought of the following approach. Is it any good?
Try autoloading from the common class library If it fails, try autoloading from the app's own local library
Part 2 of the question:

Within my apps, though, there are two types of classes: library ("vendor") classes that are only being used in that particular app so they don't need to be in the shared library, and app-specific classes that are the core of the app (so they, by definition, don't need to be in any shared library). I'd probably like to keep these two separate, so I'd need to add point #3 to the list above: search in the "core" class hierarchy of the local app. This gives 3 separate locations, and the problem is that they negate the advantages namespaces since there can be overlap. In which case one class will override the other during autoloading. So order of the above list would matter. And time would be wasted looking for a class in the first two places if it's more often in the third.

A solution I was considering is sticking to just one central library of classes (and dumping all app-local libraries there). Then, the core classes that belong to one app would be under an \AppName namespace.

I'm looking forward to some insights from the experts. How do you guys organize your class libraries?

Is there a recommended way to code in order to have a dual language support, especially when one is English (left to right), and the other is Hebrew (right to left)?

Should I design every page twice or is there a ready made solution?

Hi all,

I like to write scripts for my Aastra IP phone. 480i.

I have done all my scripts with Apache on windows. I thought I would try it on Linux with the AsteriskNOW FreePBX 1.4 load. Phone system software for those that do not know.

So my code is below something very simple to display on the screen. Ignore the $textmenu code that works fine. The problem is it does not open a file and do something then write the file.

On my Windows / Apache box the screen will display  on the phone and open the file and do whatever. On my Linux box it will display the screen fine but will not open that file.

Why would it be ingnoreing those PHP file commands? Any ideas? It file commands work if I run it with php script.php but not when I use my phone to launch that script. Now keep in mind Windows/Apache is fine no problem. I thought maybe it was a php.ini setting on the linux box?

<?php
$textmenu = "<AastraIPPhoneTextMenu style = \"numbered\">\n";
$textmenu .= "<Title>------- Test -------</Title>\n";

$textmenu .= "<MenuItem>\n";
$textmenu .= "<Prompt>Applications</Prompt>\n";
$textmenu .= "<URI>http://65.205.71.13/xml/menu/menu.php?source=all</URI>\n";
$textmenu .= "</MenuItem>\n";

$textmenu .= "<SoftKey index = \"1\">\n";
$textmenu .= "<Label>Select</Label>\n";
$textmenu .= "<URI>SoftKey:Select</URI>\n";
$textmenu .= "</SoftKey>\n";

$textmenu .= "<SoftKey index = \"6\">\n";
$textmenu .= "<Label>Exit</Label>\n";
$textmenu .= "<URI>SoftKey:Exit</URI>\n";
$textmenu .= "</SoftKey>\n";

$textmenu .= "</AastraIPPhoneTextMenu>\n";

echo $textmenu;



$fp=fopen("/var/www/html/aastra/awa-det/conference/test.txt","w+");
fwrite($fp);
fclose($fp);
?>

Sorry for posting this here, but for some reason the "create new topic" in linux subforum doesnt exist.


anyways i made a small php script that enables me to retrieve data between two dates. now am stuck on how i should copy it  or u0pload it into linux.

system tells me i need to upload to /usr/bin/libexec , i am there now but i dont have the slightest idea on how to do that.


help is much appreciated.

Thanks

My IDE (Nusphere's PhpED) runs on Windows but is configured so that both the web server as well as all project files are located on a development Linux server. Since the project files are located on the Linux server, the git repository is located there as well and not on my PC.  Every now again, my IDE complains that content was externally modified and whether I wish to reload the file.  Also, I was recently asked to set git's core.autocrlf to true on a project I was collaborating on which prevented me from adding any changes to git (git complained that LF will be replaced by CRLF).

The IDE allows file encoding to be changed (system default, UTF-8, Windows-1252, or ISO-8859-01) as well as the default file format (Unix, Windows, Mac, or autodetect).

Any recommendations on how best to configure git and these ide settings?

Thanks

I am using shared hosting at HostGator. I am trying to execute flare (a command line actionscript decompiler) via PHP.

According to phpinfo() my System is Linux gator1854.hostgator.com 3.2.13 #4 SMP Thu Mar 29 19:22:42 CDT 2012 x86_64

In my public_html, I have a folder named "zachafer" and inside that folder, I have a folder named "flare".

Inside the flare folder, I have the flare command line version, named "flare" and a file named movie.swf.

The flare website says that I need to run "./flare somepath/somename.swf"
Here is my code:
<?PHP

error_reporting(-1);

$swf = 'movie';

chdir("/home/infamous/public_html/zachafer/flare");
$cmd = "./flare $swf.swf";
shell_exec($cmd);

echo "Cmd: $cmd\n";
echo "File: ".file_get_contents("$swf.flr");

?>

Thank you.

Hi Guys

I am struggling with a shell_exec command in the long run, but I am trying to work down the root cause.

The error I am getting with shell_exec is a file not found error, so I thought I would start with getting to the right folder.

I have this

Code: [Select]
$sym_dir = "/root/";
$cwd = getcwd();
  echo getcwd()."\n";
  chdir ($sym_dir);
  echo getcwd()."\n";

Which in theory should 1st display '/var/www' as it does and then display the contents of root, at least that is my understanding!

However my return is this /var/www /var/www

Why cannot I move outside the web root?

Cheers
Dave

I am new to Php and the linux environment.  I have written a php program which sames a file to folder using xampp in Windows but I am having a problem with the pathway using my Ubuntu server and LAMP.  My code I used in Windows was:

$fileName = "guessbook.txt";
$file = fopen ($fileName, "ab");
if(!$file)
{
    echo "ERROR! did not create the file! Exiting.<br />;
    exit();
}

This file was saved correctly using xampp into the htdoc folder and worked fine when I called it in my browser.  I tried to substitute a Linux pathway ie: /var/www/assignment2/guessbook.txt, where guessbook is in the code but still nothing.  Can someone explain how to write the correct pathway to save this file?

Thank you

Hello,

Can I set the priority on my scripts relating to swap? Something like set_swap(10); would mean that it will be first to go into swap and set_swap(1) means it will go as a last resort and set_swap(5) being the default ?

Kind of like the proc_nice() but for memory ?

Thanks,

David

Hi,    Please I keep seeing this on my wordpress website Linux+cfcd208495d565ef66e7dff9f98764da+01+[[]].  I've tried to clear it out but to no avail. Does anyone has a solution? I will appreciate.   Thanks

Hi,
I am trying to use php to pass some commands to my linux box.From my webpage I am using the shell_exec function which is working OK but for some administrative tasks in linux I must have root access. As I am sending the commands from the webpage the apache user is used and so I am not allowed to do several tasks. I have also tried to use a bash script to pass the commands but with no result. Any ideas ?

Hello, I'm working with Zend Framework on Linux, and I'm trying to generate a CAPTCHA using Zend_Form_Element_Captcha. Whenever the CAPTCHA page loads I get this error:

Here's my code for generating the CAPTCHA:

    // create captcha

    $captcha = new Zend_Form_Element_Captcha('captcha', array(

        'font'    => APPLICATION_PATH . '/../public/fonts/LiberationSansRegular.ttf',

        )

    ));


I've checked permissions, and all directories mentioned above are accessible to root. Has anyone had a similar problem or have an idea how I can fix this?

Kind Regards,

What are your feelings regarding Linux desktop distros, and their ability to break through to mainstream usage? I started using Ubuntu about 6 or 7 years ago, and have fooled around with some other distros, but at least for me Ubuntu always seemed the best. I've got my 65 year old mom using it, and my 11 year old son playing with Kubuntu (and learning python!). I don't really consider us normal though; normal being almost too dumb to do more than check email and get on the internet.   I've managed to fully switch over to Ubuntu on all of my computers, with the exception of running Windows in a VM for Photoshop and Illustrator. Since I don't use those programs every day, there are a lot of days where I don't see Windows. I never really had a problem with Windows, except for Windows 3.1 was kind of a drag. Getting on the internet on a 56K modem on Windows 95 wasn't any fun either, but that wasn't Windows' fault. I never had the crashes and bad experiences people like to claim makes Windows suck. My main reason for abandoning Windows is just to be more involved with Linux, and hopefully reach Linux guru status someday.   I really never liked Macs. I bought one 3 or 4 years ago, and it just felt like I was paying a lot of money for a glorified (and over-hyped) linux distro. I really never liked the feel of the Finder. At the time there was no awesome text editor, and I bought a couple just to test out what I could find. Unlike Windows and Linux, it seemed like nothing is free in the Mac world. I eventually gave the Mac away. We couldn't be friends.   I'd really like to see Linux become the dominant OS. It's exciting to see how far Ubuntu has come in the years that I've used it, and I evangelize for Linux/Ubuntu quite a bit. Even still, it can sometimes seem that I am a stranger in a strange world. Do you think we can count on Linux being a bigger part of mainstream computing? One of the problems I see is that there are so many distros that a person investigating Linux may be a little overwhelmed. What do you think is keeping the masses from using Linux desktops?
