Updating Text File

[golfinggod]

Hi
I have a text file that contains

Mike:Car-1
Dave:Jet-1😛lane-3:Bike-4:Car-5

It is basically an associate array. What i am looking to do is when someone clicks on a catagory link ie Plane, update the number asside of the link by incrementing by one.

Complete example would be:

1. User ---- Clicks On Click an onclick function sends the link and user name to my page.

2. The Script then searches for the Username.

3. Checks To see if the catagory exits, if it does update the numberby one.

Can anyone help, i've been trying to sort this for days and
havent come up with anything yet.

Thanks

😉 😉

Hi gg ... we meet again.

I'll assume that you can't use a db for this ... mysql is made for this type of storage.

The way to try and work these type of problems out is to imagine yourself doing it by hand and write down the procedure you use.

Imagine there's a huge number of names and a huge number of categories.

For example ...

(1) Open file.

(2) Read (next) line.

(3) Check for 'name' at beginning of current line. If not there, go back to step (2) and continue, otherwise ...

(4) Check for 'category' anywhere else on the line. If not there, go back to step (2) and continue, otherwise ...

(5) Find the current count for the 'found' name/category, add 1 to it and re-write the line.

(6) Stop.

The technicalities are all still to do ... for example, once you've updated the line, you have to join the 'file' array together again and save the whole thing back to the file.

See how you get on.

Paul.
