Storing files in others files

[Anon]

I want to select data from several files to put them in a new single one.
The problem is that I store data line by line, for each file, and the result is that the file I created only contains the last line I stored.

Can someone help me?

Sounds like you have quite a weird script.
It should be something like this (in pseudo code)

open target file for writing.
while (there are files to include into the big file)
{
get next filename to include

open sourcefile for reading.
while (data available in source)
{
Read data from source
write data to target
}
close sourcefile
}
close targetfile

Point being that the target file is not closed untill you are completely finished with it.

If you do have to close the file, you should re-open it using the "a" mode, for appending. Otherwise you will overwrite the target file, erasing everything you wrote into it.

You got it! The problem is that I have to re-open the destination-file, several times.
However, i haven't found yet how to organize my script to re-opening the files...but i'll found.The true problem is that my script isn't very structured, it looks like a junkyard, rather than the translation of a perfect algorithm.
I guess i'll have to do with it.
Thanks to you, i am now a step closer to solving of this BIG problem.

Where am i supposed to specify this "a" option? In fopen?

Yup. in the fopen that opens the target file.

About your code: Just clean it up, look at the examples posted here and in the manual, and copy the way the code is organised.. it's quite simple.

Congratulation!It worked,at last!
Now I'll just have to "clean" my code.
The only problem left is that to merge several huge files will make other big files.
This a hard drive space problem, and Php has nothing to do with it.So this time, ALL my problem in php are solved(at least until my next script)
I owe you one Vincent.
