1) What is the source code for designing a GUI interface for searching a string in PHP-MySQL at the client end similar to the search option in mobile phone. I know that the onkeypress option is there . But as php is a server side scripting language , so what is the source code for viewing the changes at the client end after fetching information from the MySQL database?

2) Help me to write a source code in PHP-MySQL such that whatever is typed in one text box is simultaneously displayed in another text box as the typing proceeds?

3) I cannot convert the inputs from MS-Excel to MySQL. Please help me in writing the source code.

Could describe what you want? GUI interface? Please clear it.

Well...me too dint understand 1st and 3rd points.

As for the above point..This is Client side what do you want to show. So javascript can used to achieve this. PHP deals with mostly backend.
