1-to be clear, the data base contains a lot of documents (of different speciality). the user will select speciality, display all document of selected speciality, then click on document to dowload it.
each document in the database is described by a short description (abstract of the document) + the file (pdf, rar ...), its for that i use the php page to display the result of the sql query in an html table (each row contains a result: abstract+ link to download file.
the table document is like this: document_table(document_code, absract, link_to_download)
2- i have no idea on how to use google sheet !!!! is it efficient ?
3-sorry for my poor english (i speack french).
