推荐答案

如果您想从提交的表单捕捉列表，然后使用数组语法把戏，而不是列举输入字段名：

If you want to capture a list from a POSTed form, then use the array syntax trick instead of enumerated input field names:

<input type="email" name="emails[]">
<input type="email" name="emails[]">
<input type="email" name="emails[]">

这样，你需要PHP中没有猜测，因为电子邮件[] 成为一个数组隐含那么：

This way you need no guessing in PHP, because emails[] becomes an array implicitely then:

print_r($_POST["emails"]);
foreach ($_POST["emails"] as $email) {

有关数据库逃脱只需使用：

For database-escaping just use:

$db_emails = array_map("mysql_real_escape_string", $_POST["emails"]);
// that's an array too
