警告：PDOStatement::execute(): SQLSTATE[HY093]: 无效的参数号：绑定变量的数量与标记的数量不匹配

Question

在阅读了有关 HY093 的所有其他问题后，我无法弄清楚导致错误的原因

我正在上传一个 csv 文件并使用 PDO 将其值插入 mysql。

这是我得到的：

警告：PDOStatement::execute(): SQLSTATE[HY093]: 参数号无效：绑定变量的数量与标记的数量不匹配

这是我正在使用的代码：

<?php

if (in_array($extension, $allowed_extensions)) {

if (!empty($_FILES['file'])) {

    if ($_FILES['file']['error'] == 0) {

        // check extension
        $file = explode(".", $_FILES['file']['name']);
        $extension = array_pop($file);

        if (in_array($extension, $allowed_extensions)) {

            if (move_uploaded_file($_FILES['file']['tmp_name'], $upload_path . '/' . $_FILES['file']['name'])) {
                if (($handle = fopen($upload_path . '/' . $_FILES['file']['name'], "r")) !== false) {

                    $keys = array();
                    $out = array();

                    $insert = array();

                    $line = 1;

                    while (($row = fgetcsv($handle, 0, ',', '"')) !== FALSE) {

                        foreach ($row as $key => $value) {
                            if ($line === 1) {
                                $keys[$key] = $value;
                            } else {
                                $out[$line][$key] = $value;
                            }
                        }

                        $line++;
                    }

                    fclose($handle);

                    if (!empty($keys) && !empty($out)) {

                        $db = new PDO('mysql:host=localhost;dbname=pitstop', 'root', '');
                        $db->exec("SET CHARACTER SET utf8");

                        foreach ($out as $key => $value) {
                            $sql = "INSERT INTO `csat_dump` (`";
                            $sql .= implode("`, `", $keys);
                            $sql .= "`) VALUES (";
                            $sql .= implode(", ", array_fill(0, count($keys), "?"));
                            $sql .= ")";
                            $statement = $db->prepare($sql);
                            if ($value === null) {
                                $value = 'null';
                            }
                            $statement->execute($value);
                        }

                        $message = '<span class="green">File has been uploaded successfully</span>';
                    }
                }
            }
        } else {
            $message = '<span class="red">Only .csv file format is allowed</span>';
        }
    } else {
        $message = '<span class="red">There was a problem with your file</span>';
    }
}

这是我的键数组的样子

Array ( 
    [0] => SBT Interview End Date 
    [1] => Week End Date 
    [2] => YYYY Mm 
    [3] => SBT Case ID 
    [4] => SBT Response ID 
    [5] => SBT Agent 
    [6] => SBT Channel Name 
    [7] => SBT Msg Created 
    [8] => SBT Close Date 
    [9] => SBT Contact Count 
    [10] => SBT Queue Nm 
    [11] => SBT Vendor Name
    [12] => SBT Location Name 
    [13] => SBT Message Age 
    [14] => SBT Q1 (Email overall score) 
    [15] => SBT Q2 (Was your issue resovled?) 
    [16] => SBT Q201(NPS) 
    [17] => SBT Q200(Ease of contact Customer Care) 
    [18] => SBT Q186 (Verbatim) 
    [19] => FCR 
    [20] => FCR Count 
) 

这是我的价值观：

Array ( 
    [0] => 2014-06-29 
    [1] => 2014-07-05 
    [2] => 2014-06 
    [3] => 140625-057952 
    [4] => 1151071 
    [5] => agentname 
    [6] => Email 
    [7] => 2014-06-25 
    [8] => 2014-06-29 
    [9] => 0 
    [10] => AMR-EN-tech 
    [11] => tech- Agents 
    [12] => SMB - Agents 
    [13] => 4720 
    [14] => 8 
    [15] => 1 
    [16] => 8 
    [17] => 10 
    [18] => 
    [19] => 1 
    [20] => 1 
) 

任何帮助

Answer 1

问题在于您的数据，更具体地说是您的第一行：

SBT Interview End Date,Week End Date,YYYY Mm,SBT Case ID,SBT Response ID,SBT Agent,SBT Channel Name,SBT Msg Created,SBT Close Date,SBT Contact Count,SBT Queue Nm,SBT Vendor Name,SBT Location Name,SBT Message Age,SBT Q1 (Email overall score),SBT Q2 (Was your issue resovled?),SBT Q201(NPS),SBT Q200(Ease of contact Customer Care),SBT Q186 (Verbatim),FCR,FCR Count

一个字段包含一个问号：

SBT Q2 (Was your issue resovled?)

这被解释为查询中的另一个占位符，因此您的数组不匹配。

您可以通过从键中删除问号来解决此问题：

$keys[$key] = str_replace("?", "", $value);
