Editing a (config) file

[Sonnich]

Hi

I have a file with some configation in it... I am wondering how I
correct single values in there.

The most secure is to recreate the file, then rename it.

But is there a way to correct a line in the text file?
setting1=bla -setting1=blabla bla

Needless to say, there are things in there I'd like to keep at all
times.

You could use preg_replace() (have a look at php.net).

For your Example it could be

--snip--
//Read the contents of the file into $file

$file=preg_repl ace("'setting1\ =.*'", "setting1=blabl abla", $file);

//Write $file back to the file.
--snap--

Or do I misunderstand your question?

I would read the file into an associative array, update the value based
on the key, write a new file, rename it to the original. I might also
flock() the original configuration file if the operating system does not
support atomic rename/move.

You may find parse_ini_file( ) useful:

array parse_ini_file ( string filename [, bool process_section s] )

parse_ini_file( ) loads in the ini file specified in filename, and returns
the settings in it in an associative array. By setting the last
process_section s parameter to TRUE, you get a multidimensiona l array, with
the section names and settings included. The default for process_section s
is FALSE
