php - 这个查询有什么问题，它没有删除

我正在使用echo $fss其显示数据


  “ 11-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V5703211-V57032”


但是我正在使用使用此变量的删除查询，但它不起作用

<?php

 //connect to the database
 $connect = mysql_connect("localhost","root","");
 mysql_select_db("cityshoes",$connect); //select the table


if ($_FILES[csv][size] > 0) {

    //get the csv file
    $file = $_FILES['csv']['tmp_name'];
    $handle = fopen($file,"r");



    do {
        if ($data[0]) {

 $fss = addslashes($data[1]);
        $result = mysql_query("DELETE from  contacts where articleno = . $fss . ");

        echo $fss;


        }
    } while ($data = fgetcsv($handle,1000,",","'"));



}

?>

最佳答案

您以错误的方式在查询中附加变量。尝试：

$result = mysql_query("DELETE from  contacts where articleno = $fss");

要么

$result = mysql_query("DELETE from contacts where articleno ='".$fss ."'");
