mail() help sending multiple selections

[dadms]

I am using a form where multiple cities can be selected with the following code:
EXAMPLE
<select name='local[]' multiple>
<option value="ATLANTA">ATLANTA</option>
<option value="CONYERS">CONYERS</option>
<option value="CHICO">CHICO</option>
</select>

I am able to display the selection on SUBMIT with the following code:
<?php
$i=0;
while($i<count ($local)) {
print $local[$i];
print ", ";
$i=$i+1;
}
?>

How can I get the multiple selected cities to display in an email? The form emails fine with all the other variables ie name, phone numbers, etc. I just dont know what variable to use to display the selected city information in the email.

Please help.

There are several ways. I recommend:
Concatenation of the array values using implode()

$cities = implode(", ",$_POST['local']);

Please excuse me for my ignorance with the implode command since I have not used it before. However would the format be to use

<?php
$i=0;
while($i<count ($local)) {
print $local[$i];
print ", ";
$i=$i+1;
}
?>

firt and then set the new variable

$cities = implode(", ",$_POST['local']);

You don't need a loop if you implode. Imploding puts all parts of the array into one string.

print implode(', ',$local);

The above line should suffice to print out a comma separated list of all checked items.
