need help with creating arrays

[Anon]

so i have this text file that stores many email addresses like this: [e-mail], [e-mail], ..... and i want to alphabetize all these email addresses. im trying to split the string into an array and then sort it. but the problem is is that php does not think its an array. ive tried so many options and i would really like some help or even more ideas for me to fiddle around with. thanks in advance. -phil

$recipients = "./emails.txt";
$fp = fopen($recipients, "r+");
$emails = fread($fp, filesize($recipients));
$emails = sort(split(", ", $emails));

........

while(list(,$arraycontent) = each($emails)) {
echo $arraycontent . ", ";
}

Try using a separate variable that will be your array. Like this:

$emailarray = explode(", ", $emails);
sort($emailarray);

Note that sort doesn't return anything.
