lotsa ways .. try this one

$pieces=explode($date,'-');
$newdate = $pieces[2].'-'.$pieces[1].'-'.$pieces[0];

or take a look at the mysql date format or use substr() or whatever else
you can think of :-)

Fastest way, if the format is consistent:

$date_array = explode('-',$string);
array_reverse($date_array);
$string = implode('-',$date_array);

But as it is a textfile:

$oldfile = '/path/to/old/file';
$newfile = '/path/to/new/file';
$old = fopen($oldfile,'r');
$new = fopen($newfile,'w');
while($data = fscanf($old,"%s-%s-%s\n")){//change according to format
array_reverse($data);
fwrite($new,implode('-',$data)."\n");
}

That looks fine and just what i'm after - thanks dude .

Saved to disk although Floortge's method might be more practical as i
might want to add a extra line of text and only use a part of the date .
