thanks i will do it but the most of the manual will not understand direct,
that will come with time. I have read the manual for PDO, so that i can use
it. Before i has my Script with mysqli, but i have read from Prepared
Statemants and that they more comfortable and secure and so i has write. All
was good, only that not want write in database.
Okay thanks all, and im sorry that i disturb with the easy questions. All
mistakes in the script i has found with google and the manual, but when not
give message, there is problem. Often i not know the correct word which should
use to search.
For example i have a HTML Table, in this are much Code for calculate the
Stock Portfolio. <Value, Dividend, Win, Lose> Thats okay, but i search a
function with can tell php that should calculate all data in table. At moment
i have write much Variables for every stock which is in Portfolio. Better
were that i can copy the mathematical formula from one row/cell in next
row/cell, like in excel. That i not found, because i not know what is the
right words for searching.
I dont know understand what i mean? My English not the best.
Thanks for time and help.
