simple code to change elements of array

changing a specified value, or line in .txt

[NL_Cartman]

Hi,

I have some code that rewrites a data.txt file, in order to change just two values in one of the 10 lines.

I've played with array_splice , but that doesnt seem to do it;
i would like someting like this :
if ($x = $data[0]) { $data[4]=10 ; $data[5]=20 }

*leaving $data[6],7,8 un-touched

i think it shouldnt be to tough?, but again i cant get it right! :S

I don't really understand. Where do the values of $x and those in the $data array come from?

Also can you post 2-3 lines from the data file (but please, not the whole thing or your whole script)?

Typos again. Try:

if ($x == $data[0]) { $data[4]=10; $data[5]=20; }

I don't see why that wouldn't work, although admittedly I haven't tested it.

Oh right, same problem as in NL_Cartman's post on if/elseif/else problems.

NL - Look there for an explanation of how confusing the assignment and comparison operator will mess you up.
