PHP - Printf( ) Html Contains Static Russian Charachers

Quick question regarding the printf function.

I understand that printf will print a formatted string for example:

Code: [Select]
$mystring = printf('%.1f', 1.2); //Will output 1.2
However I don't understand why if I then print $mystring the result is 3

Example:
Code: [Select]
$mystring = printf('%.1f', 1.2); //prints 1.2
echo "<br><br>";
echo $mystring  //Prints 3
Please could someone explain how this works?

Hello, Well let me explain my problem to you guys.

I am using a printf function with an array, a custom function which i got off php.net

Anyways, Everytime I use it, It seems to leave random numbers at the end of the string for no reason at all.

Here is the result in source:
Code: [Select]
<td><a href="?page=download&name=DarkRP">DarkRP</a></td>
      <td>08:10:17 AM 07/08/2010</td>
      <td>Updated DarkRP from revision: 670 to revision: 67150</td>
      Array
(
    [Name] => DarkRP
    [TimeStamp] => 1281186617
    [Revision1] => 670
    [Revision2] => 671
)
    </tr>It is mean't to show Code: [Select]
Updated DarkRP from revision: 670 to revision 671but instead it has the random number 50 at the end for no reason...

Anyways heres the echoing code:

<?php
foreach($Logs as $Log){
$Time = TimeToDate($Log['TimeStamp']);
if($Log['Revision1']&$Log['Revision2']){
     $Message = 'Updated %1$s from revision: %3$s to revision: %4$d';
}else{
     $Message = 'Freshly downloaded: %1$s revision: %3$d';
}
?>
    <tr>
      <td><?php echo '<a href="?page=download&name='. $Log['Name'] .'">'. $Log['Name'] .'</a>'; ?></td>
      <td><?php echo $Time['Time'] .' '. $Time['Date']; ?></td>
      <td><?php echo printf_array($Message, $Log); ?></td>
      <?php print_r($Log); ?>
    </tr>
<?php
    }
?>
  </table>
  <br />

Functions:

function MySQLGetLogs(){
    global $Connection;
    if($Connection){
        $Query = sprintf('SELECT name, timestamp, revision1, revision2 FROM update_logs ORDER BY timestamp DESC;');
        if($Result = mysql_query($Query)){
            $Array = array();
            while($Row = mysql_fetch_array($Result)){
            $Array2 = array(array(
                                  'Name' => $Row['name'],
                                  'TimeStamp' => $Row['timestamp'],
                                  'Revision1' => $Row['revision1'],
                                  'Revision2' => $Row['revision2']
                                 )
                           );
                $Array = array_merge($Array, $Array2);
            }
            mysql_free_result($Result);
            return $Array;
        }
    }
}

function printf_array($Format, $Array) { 
    return call_user_func_array('printf', array_merge((array)$Format, $Array)); 
}

Also, I got the same issue with printf alone instead of the custom array function above.

We are able to access Static/Non-static methods with :: operator along with Class name.
What for static in this case?  I am using php5.2.x.  Please give some light on using static in php?


class One{
   function disp(){
      echo " disp here";
   }

       static function show() {
            echo "show here";
      }

}
   One::disp();
        One::show();

I write for example class Text:


class Text {
    public static function test() {
        return 'test text';
    }
}


Today I found this code:


class Text {
     
      /** 
       * Protected constructor since this is a static class.
       *
       * @access  protected
       */  
    protected function __construct(){
        // Nothing here
    }

    public static function test() {
        return 'test text';
    }
}


How much appropriate is to write this?


    /** 
       * Protected constructor since this is a static class.
       *
       * @access  protected
       */  
    protected function __construct(){
        // Nothing here
    }

Is it possible to have a static variable in php?  I want the value of a variable to remain unchanged the next time a function is called.

hey guys i have a static attribute $_exception_handler which is set to Exception and....now this value could change to a customer exception_handler but what i want to do is


<?php

catch (self::$_exception_handler $e)
{

}


but im getting an error...is there a way of doing this...any help would be greatful thanks

class below
<?php

class Autoloader
{

protected static $_exception_handler = Exception;

protected static $_classes           = array();

public static function load_library($class_name)

{

$file = ROOT . DS. LIBRARY_DIRECTORY . DS . $class_name . CLASS_EXTENSION;

try

{

self::load_class($class_name, $file);

}

catch (self::$_exception_handler $e)

{

echo $e->getMessage();

}

}

public static function load_exception($class_name)

{

}

public static function load_class($class_name, $file)

{

if (!class_exists($class_name, FALSE))

{

if (file_exists($file))

{

require_once $file;

}

else

{

throw new Exception(sprintf('Class %s not found.', $class_name));

}

}

}

}

I'm looking for some advice on the best way to achieve the following...

I'd like to change the way URLs are shown for our search results pages.

The website is a holiday rental website and currently the URLs look like this:

domain.co.uk/search?region=[value]&type=[value]&budget_low=[value]&budget_high=[value]&name=[value]&size=[value]

Ultimately I'd like them to look more like this:

domain.co.uk/region-value/type-value/budget_low-value/budget_high-value/name-value/size-value.

Any advice would be greatly appreciated.

Is it ok to do this?
Code: [Select]
class Two {

 function anything() {
   classOne::anyMethod();
 }

}

I'm sure it is but this doesn't pose very well for if I wanted to swop out one class for another. I'd then have to make changes to the code (unless I were sure all classes were named the same).

--

What I want it for (and this may be another issue), is this:

I may need to create more than one database instance:
Code: [Select]
//Database exends mysqli
$db[1] = new Database(2);//database 2 used this time
$db[2] = new Database(5);//db5

I then always use Database::closeAll() at any point in my script to ensure all connections are closed. Of course $this->close wouldn't close all instances/connections, just the one I was working on.

I know I don;t have to close all connections, but I may as well, and there are other occasions where the first part of this question applies, so please don't just respond "no need to close".

Database::closeAll() is this:
Code: [Select]
public static function closeAll() {

//closes ALL active instances (not just this one)

global $db;

foreach($db as $v) {

$db[$v]->close(); unset($db[$v]);

}
        }

Hey guys, this is just a general question.

I read about late static binding and started developing with it on my local server but I noticed that hostgator still runs on 5.2..

Should I use late static binding? (im planning to code an open source CMS)

I removed the last half of the file, but what makes the login($username, $password) function not static? I want to access it statically, but I am getting an error. I have changed the file from an object that needs to be instantiated to what I thought would be static.

Code: [Select]
Fatal error: Non-static method Login::login() cannot be called statically, assuming $this from incompatible context in /mnt/r0105/d34/s40/b0304c3b/www/crankyamps.com/include/uploads/pages/login.php on line 25
Line 25.
Code: [Select]
Login::login($username, $password);

I have a bunch of quasi-static values that must be available to the application.  Most of them are set based on settings in a configuration file.  Others are based on GET, COOKIE, or SESSION values, and utilize the database to get the actual values.  The values will never be written to or modified by the application, only read.   It seems to me that I could create some sort of superclass which includes static methods and properties, and I could access any value by something like superclass::get('some.value');  I could design the class so that the values are queried from the DB or obtained from a parsed file only the first time they are requested, and for future requests, retrieved from a static property.   That being said, I have been told from more than one person that I am just doing it "wrong".   Please let me know what is wrong about it.   Thank you

I have the following static method:
public static function query($query){
self::$num_queries++;
return mysql_query($query)or die(mysql_error());
}

I then call it like this:
$oql = Mysql::query("SELECT first FROM members WHERE member_id = '{$this->owner}'");
$rql = mysql_fetch_assoc($oql);

I then get the following error:
Quote

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /incl/php/classes/Photo.php on line 13


Why am I getting this error?

heres an example of the code i have
Code: [Select]
class someclass
{

public function run($parm)
{
system($parm);
}

public static function create($item1,$item2)
{
$this->run($item1 . $item2);
}

}

then i have a file that attempts to use the create method:
someclass::create($one,$two);

when interpreting, i get this error: "Using $this when not in object context in"

does anyone know how I can fix this? I think I understand why its wrong (the class hasn't really been set up) - I just dont know how to correct it. Is there a way I can access class functions without using $this ? additionally I tried making the run method static too, but that didnt seem to work.

I finally got my kml to display through the static maps api thinking I could then display my map on the pdf I'm generating using mpdf.  But,  it is not displaying the image in the pdf.  It works fine on a blank test page.

$kmlMap = "<img src=\"http://maps.googleapis.com/maps/api/staticmap?zoom=15&size=500x300&maptype=hybrid&path=color:0xff0000ff|weight:3|$correctedCoords \" /><br />";

Any ideas on how I could make this work with mpdf?

so my situation is something like this , i'm trying to fetch user details based on `id` that isset is getting, but some how the `variable that contains the $_GET value doesn't work` in query but when i put an static value to pdo query then it works and show the result. i have checked by doing `var_dump` of variable `$user` before query and it shows the correct value but not working in query. Below is the code i'm working with:
