php and message queue

[carobee]

hi all

i am writing an application in php.the application works with message queue.the message queue will contain values of certain configurations. what i want is that my php page should be able to take up these messages and display the configuration values.

i am able to receive the messages and update the php page.but whn there are no messages in the queue the php page will display blank in the fields of the configuration parameter. wht i want is that the php page should be able to retain the settings and not show blank fields when the message queue is empty.any help will be greatful
