Here's an idea that I think would be useful for a new function. I'd like a way to have an editable equivalent of parse_ini_file(). Many Unix programs have config files that can be edited *both* by hand, or automatically by the program. It would be nice to be able to do this in php. 

Eg if the file myfile.dat contains something like this:
//This is a custom config or data file
$foo="bar"; #comment2
$wibble="bibble";  /*comment 3*/

Then, I might call the following in my script:

edit_ini_file (myfile.dat, SET $foo="baz", UNSET $wibble, SET $bbb=4)

And as a result, the file would be appropriately changed, without modifying the comments. In this case it would become:

//This is a custom config/data file
$foo="baz"; #comment2
$wibble=false;  /*comment 3*/

I'd suggest the function should be able to:

1)SET a variable (i.e. change it if it exists, otherwise, set it)
2)UNSET a variable
3)Add a comment (after a particular variable)
4)Change a comment.

If I can be of any assistance, please let me know. I hope you like the idea. Thanks for PHP - I love it :-)

For something like this you have plenty of functions in PHP to implement it yourself in PHP code.

Yes...but why re-write this so many times? Since this original report, I think I've implemented such a system at least 4 times in different ways, and it seems to be a really obvious candidate for a core library. It's also quite hard to handle the awkward cases, notably preserving comments.
