使用 php mysql 插入数据和数组值

Question

我遇到了错误..

SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens    

告诉我如何使用下面的代码将数组数据插入数据库..

  $final= array(
         'item_name' => $sub[0],
         'quantity' => $sub[1],
         'rate' => $sub[2],
         'amount' => $sub[3]
         );
         echo "<br/>";
         echo $sub[0];
        echo "<br/>";
         echo $sub[1];
         echo "<br/>";
         echo $sub[2];
         echo "<br/>";
         echo $sub[3];


         }

以上代码的输出

soap
2
15
30
Surf
1
30
30
RIN
10
20
200 

我想将以上所有数据插入数据库中的这些字段item_name, quantity, rate, amount,...发现我已经编写了代码，但它显示错误并且无法正常工作

    $input="5001@Cust1|MID1|12|20-05-2015@soap|2|15|30&Surf|1|30|30&RIN|10|20|200@20|240";          
                //new code added
            $string1 = explode("@",$input);

    echo $string1[0]; 
    echo "<br/>";
    echo  $string1[1]; 
    echo "<br/>";
    echo $string1[2];
    echo "<br/>";
    echo $string1[3];

    $stringitem=$string1[1];
    $stringitem1=$string1[1];
    $stringitem2=$string1[2];
    $stringitem3=$string1[3];

    $stringtotal=explode("|",$stringitem3);
    echo "<p>Bill Amount</p>";
    echo $stringtotal[0]; 
    echo "<br/>";
    echo  $stringtotal[1]; 

    $stringnew=explode("|",$stringitem1);

    echo "<p>Machine Data</p>";

    echo $stringnew[0]; 
    echo "<br/>";
    echo  $stringnew[1]; 
    echo "<br/>";
    echo $stringnew[2];
    echo "<br/>";
    echo $stringnew[3];

    echo "<p>Product Data</p>";


    $stringnew1=explode("&",$stringitem2);
     $p_count = count($stringnew1);

     for($i=0;$i<$p_count;$i++){
     $sub = explode('|',$stringnew1[$i]);

     $final= array(
     'item_name' => $sub[0],
     'quantity' => $sub[1],
     'rate' => $sub[2],
     'amount' => $sub[3]
     );
     echo "<br/>";
     echo $sub[0];
    echo "<br/>";
     echo $sub[1];

您的 SQL 查询需要以下 10 个参数：

:customer_id, :machine_id, :bill_no, :bill_date, :item_name, :quantity, :rate, :amount, :discount, :bill_amount

但您只在execute 中提供7。
