--> I N C L U D E < -- O R --> F O P E N < -- ?

Hi, I am not a PHP programmer. (Sorry Guys;-) Although, I am working on a PHP portal type site, where I need to integrate as seemlessly(?) as possible an outside specialized leased Search Engine Service done with ASP (I suppose? ".asp"). I have been looking everywhere for this info. Just can't seem to get it all together. I done some tests but the images acompanying the Search form are not following. I suppose if I ask the them to put absolute paths... ? --- 1. Is it technically possible with PHP to interact with the engine's pages and the results it pushs so that it feels as if it was part of the site? --- 2. I don't understand the differences between "include" , "fopen" and even "@fopen". What would be the best way to do the job if it is "doable" of course ;-) Best regards, Yves
