Writeing to line X

[Anon]

Hi back again,

I have this script,

$filename = $SCRIPT_PATH . "/businessdb.cfg";
$fp = fopen ("$filename","w");
$content = $business."|".$password."|".$phone."|".$address."|".$picture."|".$url."|".$email."|".$info;
fwrite ($fp, $content);
fclose ($fp);
?>

How can i tell is to write to line "X" in the file ?
Line X would ceom from a varable "number=1" from another page

If you're talking about a plain text file, you don't have any way to tell it to write a certain line. The best you can do is sequentially process the entire file, reading it from one file and writing it to a new one, and modify the desired line on the fly, or else read the entire file into an array in memory, modify the desired line and then write the whole thing back.

It sounds like you are really talking about database-type functions, in which case you really really do need a database.

Humm some one told me it can be done,,
I cant see why you can read from line X (done that allreaddy)
But cant write to it (sounds WEIRD if that cant be done!)

I had a try of using the line i use to read the file then just replace the write places and it don't work
