So how do I make it so it just set's the variable's that are sent in the $_POST because i wanna write it so that if the value isnt changed, it wont send the $_POST and wont update the config file..

Yeah, but will that just replace the data that is present already there? I dont wanna have duplicate entries in there or i'm affraid it wont read it. The origional code you gave worked but it just ran in a big loop.

That particular example will replace the whole file.

If you only want to replace a particular option then that's different - but we don't know what you are trying to do.

What i'm trying to do is just make a web intigration to edit shoutcast .conf files. I have everything else execpt for now like I was saying, that code worked, I just want it to halt after it updates that line of code.


In the simplest form:

$new_textcontent = 'post_field=' . $_POST['post_field'] . "\n";

$fp = fopen($filename, 'w');
fputs($fp, $new_textcontent);
fclose($fp);


I'd suggest cleaning up $_POST['post_field'] before just writing it (eg making sure it is only numbers, whatever data you actually want to keep in it).

What do you want it to do?

We have absolutely no idea exactly what you're trying to achieve - that was just a guess because you're posting a form and want the new values written to a file.

Ok, The fix is just doing something like this...

list($variable, $data) = explode("=", $x);

But now my problem is trying to figure out how to update that data with <form> post ect...

So the main page would get

MaxUser=32

It would read that info and put it in to a form field, which I have.

Now I gotta get it to take and make it so that a new value can be put in that field and updated back in to the text file. I have searched all over google for about 4 hrs looking for something like this but no go, any help would be appricated.




This is a simple example but it should work for you:

$new_textcontent = "";

foreach($_POST as $area => $value) {
  $new_textcontent .= $area . "=" . $value . "\n";
}

$fp = fopen($filename, 'w');
fputs($fp, $new_textcontent);
fclose($fp);

How about posting your solution as well? Maybe someone will find it useful.

I'm trying to figure out how to read specific data from a text file that
is already written. Example

MaxUser=3D32
PortBase=3D8000

I want to be able to have php read them specific pieces of info so I can
put them in to forms and update them via php.
Any help would be appreciated.
