fwrite() arrays [0] thru [x-1]

[jkb3614]

so basically i have a page of inline data where one line (x) needs to be edited.

 

i have everything set up EXCEPT...

 

i need help on how to write the first variable of an array through the line before line "x".

 

i.e. something along the lines of fwrite($rex[0-(x-1)])

                                                                  but of course this doesn;t work

i split the whole file into an array using file()

 

also i'm not the greatest with php can anyone help?

if you want to write the line before the line of index x, then just do

fwrite($rex[$x-1]);
