我有这个 PHP 代码:

for($i=1; $i<=$_POST["counter"]; $i++)
{
    if($_POST["checkbox$i"])
    {
        //select the billing_pdf row
        $sql="SELECT * from billing_pdf_archive where sequence = '".$_POST["checkbox$i"]."' ";
        $rs=mysql_query($sql,$conn);
        while($result=mysql_fetch_array($rs))
        {
            //now select all contacts for the company who receive all accounts emails
            $sql2="SELECT * from contacts where company_sequence = '".$result["customer_sequence"]."' and receive_accountsemails = 'yes' ";
            $rs2=mysql_query($sql2,$conn) or die(mysql_error());
            if(mysql_num_rows($rs2) > 0)
            {
                while($contacts2=mysql_fetch_array($rs2))
                {
                    //generate the list of emails address in an array
                    $emails_list[] = $contacts2["email"];
                }
                $emails_list = implode(',',$emails_list);
            }
        }

        $ins_sql2="INSERT into email_attachments (email_seq, attachment) values ('".$email_sequence."', '".$result["pdf"]."') ";
        $ins_rs2=mysql_query($ins_sql2,$conn) or die(mysql_error());

        $up_sql="UPDATE emails set emailto = '".$emails_list."' where sequence = '".$email_sequence."' ";
        $up_rs=mysql_query($up_sql,$conn);
    }
}

但我收到此错误:

致命错误:中的字符串不支持 [] 运算符

在上面写着:

$emails_list[] = $contacts2["email"];

我在其他页面上使用相同的数组代码(没有 for 循环)并且它们工作正常

我究竟做错了什么?

$emails_list[]您在第二个 while 中填充数组$contacts2["email"]。在下一行中,将数组内爆为字符串。

下一个结果(第一个 while 循环)$emails_list是一个字符串。现在您无法将字符串转换为数组

尝试这个:

        $emailsListData = array();
        while($contacts2=mysql_fetch_array($rs2))
        {
            //generate the list of emails address in an array
            $emailsListData[] = $contacts2["email"];
        }
        $emails_list = implode(',',$emailsListData);

您已经在页面中的某个位置使用 $emails_list 作为字符串,例如 $emails_list = 7;

并再次使用它

$emails_list[] = 数组(1,2,4);
