I believe that PHP's filesystem will fit what I want to do but I am having trouble finding the appropiate items to do the following: -Delete a selected line from a text file (For Example: Remove line 40 of a 100 line text file. Therefore, what was line 41 is now line 40 and there are now 99 lines in total) -Add a line to a preexisting text file (For Example: A string is added to the end of the file [A 98 line text file becomes 99 line] or a string is inserted at a selected line of in the file[The string is made line 45 and what was previously line 45 becomes line 46]) -Edit/replace a certain line in a preexisting text file (For Example: Line 34 which says "Hello I am sam" is changed to say "This is John") If any of you know a function or a method that can do either of these, do tell.
