Looks like you're using fopen() incorrectly. Try:

  fopen("$file_name","r+");

[PHP] writting to files

[Jas]

Ok, I have been working on this for awhile and cannot seem to get the fwrite
function to work.  Here is the code:
\\ index.php


  
  
  

This works as I need it to, opens the file and then removes the first < so
that it won't be parsed as a php script.
\\ edit_passwords.php

I have read and write permissions set on the file and the directory.  It
will not write changes to the file.  Any pointers?

Thanks for the response so far...

I'm still not sure on how to get the code to start on a new line in the file (yes they 
are text files). Say I wrote variable1 to line one how do I get it to write the next 
variable to line two?

Thanks

  Assuming you're talking about text files:

  A. suck the whole thing up in memory, change it there, write it back out.
  B. open a temp, copy till the line of interest, write your change,
 copy remainder. mv/cp the temp to the original.
  C. read to line of interest, ftell(), suck remainder into memory.
 ftruncate(), fseek(), write your changes, write out the remainder.

Just as a note: for large (text or binary) files, it's better to use a
temporary file (see tmpfile()) and limit the in-memory buffer to smth like
1024. After finishing, do not close the tmpfile (this would automatically
delete it), but lseek and copy back to the original. Anyone know any
better ways to deal with large file contents?

thx,

Hi,

Anyone know how I can write and read to different lines in a file rather than just 
adding to the text already on the first line of the file?

Thanks
