半数据插入但剩余数据不更新特定会话通过

Question

在foreach循环中输入数据但没有插入到数据库中有一半数据插入数据库但是没有工作foreach循环.....插入半数据后，没有更新剩余的一半数据.....为什么会这样？

代码是

 <?php
include_once('config.php');
if(isset($_POST["email_verify_btn"])) {

        $email = $_POST["email_verify"];
        $i = 1;
        if(strpos($email,"\n")) {

        $text = explode("\n",$email);

            foreach ($text as $abc) {
                $i++;
                                $status = 1;
                                $c_by = 1;
                                $c_date = date('Y-m-d H:i:s');
                                $c_ip = $_SERVER['REMOTE_ADDR'];
