I have a text file with some configuration value. There a comment starts with a # I am trying to find a regular expression pattern that will find out all the lines that start with a #

So, sample file:

1st line
#test line this 
line #new line
aaaa #aaaa
bbbbbbbbbbb#
cccccccccccc
#ddddddddd

I want to find

#test line this 
#ddddddddd

because only these two lines start with # I tried the following code:

preg_match_all("/^#(.*)$/siU",$text,$m);
var_dump($m);

But it always outputs empty array. Anyone can help?
