manipulating CSV files

hi folks, I have a CSV file. Data is separated by ','. For example: -94.86524,42.059444,A,B,X -96.86524,42.059444,A,B,Y1 -99.86524,42.059444,A,B,C1 I want to interactively insert the user_name (passed by a php variable) into the first "field" to insert then on my DataBase. Peter,-94.86524,42.059444,A,B,X Jan,-96.86524,42.059444,A,B,Y1 ... I know there is a command (fwrite) to write, but I can't figure out how to start with it... Afet open csv, etc. I think I should first check when there is a "return" (we change of file), then I add the "user_name" parameter and repeat it as long as there is some record. Any workaround or code doing something similar for a newbie in php, please?
