PHP检测文本字段中的换行符

Question

I'm trying to split up the POST data of a text form field. I want the data split by each line, using the explode() function

So first I check the POST result for strange characters;

$mails = mysql_real_escape_string($_POST["emails"]);

Then I run this, which doesn't work

$emails = explode("
", $mails);

What am I doing wrong? Is it not ? Is my sql escape bit messing me up?

You could also convert the new lines to breaks, then explode from the <br />s:

$mails = mysql_real_escape_string(nl2br($_POST["emails"]));
$emails = explode("<br />", $mails);
