php6

Why php6 is more effective than all version of php..?

There are few reasons frds..

   

 1.Unicode

This equates to PHP having to store both Unicode and non-Unicode variants of class,
method and function names in the symbol tables.
In short - it uses up more resources.

2. Register Golbal to go

This means that php6 will finally break all PHP3 era scripts (or any script using reg globals)
with no recourse at all but to re-code it.

3. Safe mode to go

    php6 is most useful to use in safemode working than others. and found  E_CORE_ERROR.and make
    php  secure.

4.Fast CGI always on.
 
   The FastCGI code will be cleaned up and always enabled for the CGI SAPI,
    it will not be able to be disabled.

5.Register long array to go

Now the HTTP__VARS  not globals.  Well if you're not already using $_GET, $_POST, etc -
start doing so now, because the option to enable long arrays is going
(and will throw an E_CORE_ERROR).

6. Extension Movements
 
   The XMLReader and XMLWriter extensions will move into the core distribution and
will be on by default.

7.PHP Engine Additional.

  It can add some additional funactionality in php6.
