Writing to a File

[Anon]

Is it possible to write to a file
For Ex: if I want to modify daily the 10th line of a particular file(ex: index.html or index.php), Can I do it with the fwrite() function? Please help neede urgently.
Thanks

Try this:
$filename = "path/filename";
$old_file = file( $filename );
$new_file = fopen( $filename, 'w' );
$old_file[9] = "Whatever it equals";
foreach( $old_file as $file_line )
{
fwrite( $file_line );
}
fclose( $new_file );

That should work.
