php - 电子邮件脚本发送电子邮件但抛出无法重新声明 spamcheck() 错误

Question

我有一个脚本可以将电子邮件发送到多个电子邮件地址，脚本应该在完成后重定向到成功页面，电子邮件发送正常没有问题，但是我收到以下错误而不是重定向。

Fatal error: Cannot redeclare spamcheck() (previously declared in /websites/123reg/LinuxPackage22/br/ig/ht/MYSITE.co.uk/public_html/admin/mailinglistsend.php:87) in /websites/123reg/LinuxPackage22/br/ig/ht/MYSITE.co.uk/public_html/admin/mailinglistsend.php on line 87

代码如下

<?php
//initialize the session
if (!isset($_SESSION)) {
  session_start();
}

require_once('../Connections/BrightLights.php'); 

if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

mysql_select_db($database_BrightLights, $BrightLights);
$query_mailinglist = "SELECT * FROM mailing_list WHERE subscribed = ''";
$mailinglist = mysql_query($query_mailinglist, $BrightLights) or die(mysql_error());
$row_mailinglist = mysql_fetch_assoc($mailinglist);
$totalRows_mailinglist = mysql_num_rows($mailinglist);

error_reporting(E_ALL & ~E_NOTICE);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);




?>
<?php 



$subject = $_POST['subject'];
$body = $_POST['body'];

do {

$name = $row_mailinglist['name'];
$email = $row_mailinglist['email'];



    $email_from = 'mailinglist@MYSITE.com';
    $email_subject = "$subject";
    $email_body = "
    $name,

    $body

    $to = "$email";

    mail($to, $email_subject, $email_body, $headers);





    function spamcheck($field)
    {
        //filter_var() sanitizes the e-mail
        //address using FILTER_SANITIZE_EMAIL
        $field=filter_var($field, FILTER_SANITIZE_EMAIL);

        //filter_var() validates the e-mail
        //address using FILTER_VALIDATE_EMAIL
        if(filter_var($field, FILTER_VALIDATE_EMAIL))
        {
            return TRUE;
        }
        else
        {
            return FALSE;
        }
    }

    } while ($row_mailinglist = mysql_fetch_assoc($mailinglist));


mysql_free_result($mailinglist);

    header('Location: mailinglist-new.php?sent');

?>

感谢您的帮助:-)

您在 do - while 循环中声明您的函数(what for?!)。把它拿出来。一切都会好的!
