Quick strcmp query

What's the advantage of using strcmp as opposed to == for strings.

For example I have :

$a=array('dothis','dothat','dosomethingelse');

$BLOCK_RUN=$a[date("w")];


if($BLOCK_RUN=='dothis')
etc etc....

Is there any reason to use this instead:

if(strcmp($BLOCK_RUN,'dothis')==0)
etc etc....


I don't see an advantage for strcmp here.....

'==' tests for equality, strcmp() also for alphabetical order.

Not in this case.
