XML – SVG

Why XML?
*XML is a standardized format
* Can be read and written by most languages
* XML is human-readable (if written well)
* XML is flexible
* Can be altered with style sheets
* Transformations between different types of XML
* e.g. HTML table to chart
* Supports records, lists, and trees
* Plain text; platform independent

Why XML … Not
* Verbose and redundant
* Can be difficult to read
* Inefficient to parse, store, and transmit
* Parsers must deal with arbitrary levels of nesting and errors
* No concept of data types
* Hierarchical not relational

SVG: Scalable Vector Graphics
#A vector-based graphics format in XML
#Graphics consist of lines, shapes, colors (not pixels)
#Can be viewed by most modern browsers
#XML format, like HTML
#Can use JavaScript for animation / interactivity
#CSS for style

SVG Example

SVG example
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1" xmlns="http://www.w3.org/2000/svg">
<circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/>
<circle cx="200" cy="50" r="40" stroke="black" stroke-width="2" fill="green"/>
<circle cx="300" cy="50" r="40" stroke="black" stroke-width="2" fill="yellow"/>

PHP vs. Java/JSP

Java is…
* Strictly object oriented
* Strongly typed
* More clearly structured
* More complex
* JSP requires special server (Tomcat)

PHP is…
*Procedural (like C), with some objects
* Weakly typed, generally more flexible
* Generally faster to develop in
* Available on most web servers
* Easier to make messy code
* No namespaces
* Vague function definitions

Protect file uploads via PHP

Check server-side MIME type of uploaded files

The PHP form variable $_FILES['file']['type'] does not return correct mime type, so we have to use some php functions like…….
> finfo_file()
> getimagesize()
> exif_imagetype()

if(version_compare(substr(PHP_VERSION,0,1),5) == -1)
{
$san	= finfo_open(FILEINFO_MIME);
$mime	= finfo_file($san,$FileName);
$tmpvar = explode(";", $mime);
finfo_close($san);
if($mime == "image/jpeg")
{
echo "this is jpeg";
}
else
{
echo "this is not jpeg";
}
}

One can use getID3 [http://getid3.sourceforge.net/] classes to get mime type other than images….

Don’t upload to a web accessible directory

Protect your directory to execute perticular file type by putting a .htacces file in directory

AddType text/plain .php .js .cgi

SOAP vs REST

A set of functions that can be called remotely using HTTP
> Used by other programs and programmers
> Define functions and arguments
> Return data rather than a Web page

SOAP	REST
> Requires WSDL files to publish resources > XML in request and response > Developer needs to know the XML syntax for the service > Uses Remote Procedure Calls (RPCs) over HTTP > XML-wrapped RPC difficult to “sniff”	> Uses a URI to locate objects > Passes method calls as GET parameters > Uses well-known calls (GET, POST, PUT, DELETE) > Uses plain HTTP > Calls can be secured by the firewall or via certificates

Zend Framework with xampp

The leading open-source PHP framework has a flexible architecture that lets you easily build modern web applications and web services.

This is the practical information about zend framework with xampp, I want to use zend library with xampp but

Error: ” Warning: require_once(Zend/Loader.php) [function.require-once]: failed to open stream: No such file or directory in D:\xampp\htdocs\zendframework\htdocs\index.php on line 2

Fatal error: require_once() [function.require]: Failed opening required ‘Zend/Loader.php’ (include_path=’.;\xampp\php\pear\’) in D:\xampp\htdocs\zendframework\htdocs\index.php on line 2 “

Solution: Zend Framework requires no special installation steps. Simply download the framework,
extract it to the folder you would like to keep it in, and add the /library directory to your PHP include_path.

Just set include path in main php file where you want to access zend framework classes like….

<?php

//set include path to /library
set_include_path("D:\xampp\php\ZendFramework-1.8.0\library");

/*  remaining php code here */

//..........
//..........
?>

Happy zend + xampp
