In Linux (Ubuntu, Fedora) OS we have the PHP executable available in shell, so we can run command line php script. But in windows to do so, we have to set PHP executable as Windows path variable.
We can do that in two ways ...

1. Open the command prompt (start -> run -> cmd)
and type: set PATH=%PATH%;C:\path_to_php
here, "C:\path_to_php" is the physical folder where php.exe is located. In my case its on C:\xampp\php.

Now we can run PHP script from anywhere we want like this:
D:\>php -v
PHP 5.2.5 (cli) (built: Nov 8 2007 23:18:51)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with Zend Extension Manager v1.2.0, Copyright (c) 2003-2007, by Zend Technologies
with Xdebug v2.0.2, Copyright (c) 2002-2007, by Derick Rethans

Main problem of this method is this will affect only a single command prompt.

2. The second method will affect all command prompts. First, right click on "My Computer", then click on "Properties" - a dialog box with some tabs will appear.
Now from the tab named "Advanced" click on the button "Environment Variables". This will open the Environment Variables box. Now choose the Path variable from the system variables box and click Edit.
Append the variable value with:

;C:\path_to_php

here, "C:\path_to_php" is the physical folder where php.exe is located. In my case its on C:\xampp\php.
';' character is used to separate directories in the var, so be sure it’s present.

Thats all.

Fckeditor (Html text editor) v-2.6.4 does not have automatic image resizing feature on upload or at least i don't know :( whether this editor has this feature. So to be able to resize picture on upload via fckeditor i bring some changes on "commands.php" file of fckeditor files. This file located on '\editor\filemanager\connectors\php' of the fckeditor folder. Open this file and

1. go to line # 219. It looks like

move_uploaded_file( $oFile['tmp_name'], $sFilePath ) ;

This line is under the function 'FileUpload'

2. Now change the line to

if($sExtension == 'jpg' || $sExtension == 'jpeg' || $sExtension == 'gif' )
{
  $uploadedfile = $_FILES['NewFile']['tmp_name'];

  // Create an Image from it so we can do the resize
  $src = imagecreatefromjpeg($uploadedfile);
      
  // Capture the original size of the uploaded image
  list($width,$height)=getimagesize($uploadedfile);
     
  // For my purposes, I have resized the image to be
  // 300 pixels wide, and maintain the original aspect
  // ratio. This prevents the image from being "stretched"
  // or "squashed". If you prefer some max width other than
  // 300, simply change the $newwidth variable
  $newwidth=300;
  $newheight=($height/$width)*$newwidth;
  $tmp=imagecreatetruecolor($newwidth,$newheight);
      
  // this line actually does the image resizing, copying from the original
  // image into the $tmp image
  imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
      
  // now write the resized image to disk. I have assumed that you want the
  // resized, uploaded image file to reside in the ./images subdirectory.
  $filename = $_FILES['NewFile']['tmp_name'];
  imagejpeg($tmp,$filename,100);
  move_uploaded_file( $filename, $sFilePath ) ;
  imagedestroy($src);
  imagedestroy($tmp);
}
else
{
  move_uploaded_file( $oFile['tmp_name'], $sFilePath ) ;
}

3. thats all.

It works for me and hope will for U :)

We often show latest news from various News Site RSS feed in our site. We can show this news as like as scrolling news in the TV channels. We called it news ticker. Here i show the steps that i do to show those news like TV channel scrolling news. I use this javascript file to do this. Here is my steps

1. create a index.php file and add these lines between body tag:

<DIV ID="TICKER" STYLE="width:520px; overflow:hidden"  onmouseover="TICKER_PAUSED=true" onMouseOut="TICKER_PAUSED=false">
<?php
include("xmlparser.php");
?>
</DIV>
<script type="text/javascript" src="webticker_lib.js" language="javascript"></script>

2. Download the webticker_lib.js javascript file from here

3. create a .php file name xmlparser.php and put those line:

<?php

$insideitem = false;
$tag = "";
$title = "";
$description = "";
$link = "";

function startElement($parser, $name, $attrs) {
 global $insideitem, $tag, $title, $description, $link;
 if ($insideitem) {
  $tag = $name;
 } elseif ($name == "ITEM") {
  $insideitem = true;
 }
}

function endElement($parser, $name) {
 global $insideitem, $tag, $title, $description, $link;
 if ($name == "ITEM") {
  printf("<a href='%s' target='_blank'>%s</a> ",
   trim($link),htmlspecialchars(trim($title)));
  $title = "";
  $description = "";
  $link = "";
  $insideitem = false;
 }
}

function characterData($parser, $data) {
 global $insideitem, $tag, $title, $description, $link;
 if ($insideitem) {
 switch ($tag) {
  case "TITLE":
  $title .= $data;
  break;
  case "DESCRIPTION":
  $description .= $data;
  break;
  case "LINK":
  $link .= $data;
  break;
 }
 }
}


  $xml_parser = xml_parser_create();
  xml_set_element_handler($xml_parser, "startElement", "endElement");
  xml_set_character_data_handler($xml_parser, "characterData");
  $fp = fopen("http://bangla.irib.ir/index.php?option=com_rss&feed=RSS2.0&no_html=1","r")
   or die("Error reading RSS data.");
  while ($data = fread($fp, 4096))
   xml_parse($xml_parser, $data, feof($fp))
    or die(sprintf("XML error: %s at line %d", 
     xml_error_string(xml_get_error_code($xml_parser)), 
     xml_get_current_line_number($xml_parser)));
  fclose($fp);
  xml_parser_free($xml_parser);

?>

Here "http://bangla.irib.ir/index.php?option=com_rss&feed=RSS2.0&no_html=1" is the rss feed address, from that i retrieve news. So we to change this address when we want to retrieve news from other RSS feeder.
Thats all. Now Run the index.php file and get news ticker in action.
