How to detect languages from (=> LTR vs RTL)

[Michelle Konzack <linux4michelle@xxxxxxxxxxxxxxx>]

Hi colleges and gurus,

I coding a whole "web office" and one of my problems is "LTR vs RTL".
If I have for exanple an E-Mail I use a

    <div style="direction:$DIRECTION">
      $SOME_TEXT
    </div>

but HOW can I detect the type of $SOME_TEXT  from  within  PHP,  to  set
$DIRECTION? (RTL or LTR) correctly?

And how can I do this with mixed Text (by  line  or  entired  paragraph)
like:

   german       <- must be LTR
   persian      <------------------- must be RTL
   english      <- must be LTR
   arabic       <------------------- must be RTL
   french       <- must be LTR
   jidisch      <------------------- must be RTL

Ayn Iranian (Moxhtar?), Arabs (Jasin?) or Jews (Dotan?) here  which  can
help me please?

Thanks, Greetings and nice Day/Evening
    Michelle Konzack
