Multiple Rows into One String

[fjwolz19]

I have a MySQL Database with a table containing a column for email addresses. I would like to create a string to use in php that lists all the addresses that are in that column seperated by commas. Is there an easy way to do this, either by using a loop in php or some command in MySQL?
_____________________________________________
This is what I want to get (with generic emails listed here).....

email.address@whatever.com,fake@blah...ng@e mail.com
_____________________________________________
This is what I have

recipients table
email
emailaddress@whatever.com
fake@blah.com
testing@email.com
_____________________________________________

Thank you in advance for any assistance you can give me.

um, i think this will work.
add this to the PHP script that lists them:

$lines = str_replace("\n",",",$whateverReadsTheDatabase);
echo $lines;
