Err: gateway.php not found while executing Flex application for PHP

Here is the reason,


Adobe Flash Builder 4.5 uses Zend PHP Framework for connecting and retrieving the database data's by default. Library files of Zend framework normally placed under webroot or inside the Flash builder application directory. This makes the path confusion and throws that error while we try to bind the data with any of our controls like Data Grid or something else.


Solution:


Try to use PHP (runtime) instead of Zend for PHP connection method to get the exact result. Use menu "Data-> Connect to PHP (Runtime)" instead of using the link given in the tool bar called "Data/Services". You may say, both are there for do the same task. But the interface given for each option is differed from each other.
