HI, I want to find whether 2 strings are matching... consider the 2 strings,

 my $string1 = ~cake,pastry
 my $string2 = pastry,~cake
[download]

the result should be the string1 & string2 are matching...as they are having same words in different order. and if the 2 strings are

my $string1 = cake,pastry
my $string2 = ~cake,pastry
[download]

then the result should be the 2 strings are not matching... though they are in the same order,"cake" is different from "~cake" I searched in Q&A section but didnot find the correct solution.sorry to bother if the answere is already present here. -Madam
