I have these strings:
$txt1 = "8,742 MW";
$txt2 = "7,750 KW";
$txt2 = "2,350 GW";
I need a regex to find the valid float number into these strings... How can I do it ? Thanks.

This one should do it :
[-+]?([0-9]*\,)?[0-9]+
Or if you'd like to convert directly to a float by taking the comma "," as a dot ".", then I think you should set your locale to a french one as stated here :
setLocale(LC_ALL, 'fr_BE.UTF-8');

To match float value try following regexp:
(\d+(?:,\d+)?)
Also you can just cast it to a float using:
$floatVal = (float) "8,742 MW";
