Edit row in flat file

[buzzt]

I am able to retrieve the row I want (from a flat file). Now I would like to be able to edit and/ or delete that row only without affecting those before or after. Is there a way?

Here's how I am getting the row info ($ed is the id for that row which is posted to the page by clicking a link with the id for that row in it.)

   $file  = fopen("ans.txt","a+");
   $count = file("ans.txt");
   $num   = count($count);

   for ($i=0; $i<$num; $i++)
   {
     $edrow = explode("|", $count[$i]);
     if ($edrow[0]==$ed)
     {
     	$edid   = $edrow[0];
     	$edqrow = $edrow[1];
     	$edarow = $edrow[2];
     }
     
   }

That's a good point... in the solution I provided you would need to use a separate function (unset()) to do a deletion, whereas with array_splice you can just modify arguments.

My commentary on overly complex is really only based on the fact that array_splice works on offsets instead of keys, and in my personal experience I have an easier time working with keys.

I'm just joking. No offense taken.
