Explode() with Fwrite()

[stragy]

Hello,

My question regarding PHP is: how do I write to a specific part of an exploded string of a file?

For example heres the text file, call it 'test.txt':
peaches mangos strawberries
cats dogs birds
jack jim jake

now I want to replace the second line and the second word, which would be "dogs" with "monkies"

so I set the pointer of the file to the second line and I explode the line with spaces " " so $string[1] points to dog, now how would I change it to monkies? I have no clue how I would do this with fwrite or what...

thanks~

you have to read the whole file, string_replace() and write the whole file, of course a db would probably be better

That seems highly inefficient, are you sure there isn't a way to do that except with only one line of a file?:queasy:

that's why i mentioned db, files are not designed for this sort of thing
