if $arr is a array as in
$arr =array('a','b','c');

output should be a combination of various elements

output

'a','b','c','ab','ac','bc','abc' 

this should be a generic code 
as in if elements are as array('a','b','c','d','e')

Based on the code given, how are we supposed to know what the output should be? There is no mechanism to output anything in anyway. Explain further please?

here it is

see say i have an array('a','b','c')

i require the code which generates the output as
a,b,c,ab,ac,bc,abc

for array('a','b','c','d')

a,b,c,d,ab,ac,ad,bc,bd,cd,abc,abd,bcd,bda,abcd

hope u understand the question
