Once I passed variables through webview to the server (from B4A). A PHP script took care of the variables by using $_GET.
How can I the same way read a variable from PHP, and have the variables passed back to the client as alternative ways?
I think this could be done by using the HTTP library, and add Arrays as values. Can this be used for both GET, POST and Return value as well?

Example

http://www.domain.com/?firstname=Erel&company=Anywhere software
PHP will read variables with GET.
But how to send back to the client in similar way? From SERVER -> to CLIENT

See Erel's thread. PHP uses f.e. the "echo" or "print" method. What you "echo"/"print" will be received in Job.GetString...

PS: See my signature, too. Use "PHP" to search the forum. There are tons of examples.

Thanks KMatle, to be specific which library do you refer to and recommend, since there's many ways to fry a chicken .
What I need is a solution that works for B4A, B4i and also from B4J. Advice is appreciated, Cheers Roger

Sorry my misstake, I did not pay attention to the links under your name. httputils2 looks interresting. Might be what I'm looking for.
I was looking for a simple and convenient way to achieve this, and I think your solution looks easier because I'm not a fan of Json.
Hopefully httputils2 can do the same work, anyway thanks for clearing this out.

For calling webservices like php just use OkHttp and OkHttpUtils and see my examples...

see here for php-database examples and refer your provider about the credentials. Some have own servers for each db (like my does).

Great, but I allready know PHP even though that site is a good reference. I will study the okhttp and okhttputils.. those are new to me.
Recently I covered SQLite with source code example, so this seems like a natural step so I will gladly be an apprentice of your teachings
Thank you lord KMatle

Hey KMatle I need your help I've covered your tutorials on in this case jokhttputils2 and managed to read a record from mySQL database on my server, which is great but I wonder how can I associate each cell that is read with a variable (in this case B4J but it shouldn't matter I think), instead of using multiply reading just to store each cell into a variable so that I can use the database info from memory. How do I handle this in jobdone or is there another way? i.e. how to store Firstname and Lastname data from the database into string variables from jobdone. Thanks
