Remove special characters & spaces in a string 1

[thendal]

Hi all, How can i remove all the special character and spaces from a string.

$test="7797 telegraph rd, apt # B22,city,state";

Output:

7797telegraphrdaptb22citystate

I tried something like this

$test="7797 telegraph rd, apt # B22,city,state";
$test=~s/ //g; #remove all the spaces in the sting

$test=~/(a-zA-Z0-9)/;

$output=$1;
#I try to match alphanumeric alone and capture it a string it didn't work

it prints out null..

any thoughts ..?

Thank you.

How about:
[tt]
$test=~s/[^a-zA-Z0-9]//g;
[/tt]
