Question

生成我的表名，它包含以下列：(id, username, password) - 没什么特别的：）

我的users.text有这个：

expert1001 01995056
expert1002 58381484
expert1003 03154500
expert1004 45885204
expert1005 24750107
expert1006 14096885
expert1007 81250562
expert1008 00910766
expert1009 99830724

我试图将这些生成的用户导出到我的数据库，但是我试图检查用户是否已经存在;如果是这样的话，我会转到下一个，但我收到了这个错误而且我没有看到它。

您的SQL语法有错误;查看与您的MySQL服务器版本相对应的手册，以获得在＆＃39;＆＃39;附近使用的正确语法。在第1行

（PHP版本5.3.5）

<?php
$host = "localhost";
$user = "root";
$pass = "1234";
$db = "users";
$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!");

我做了一些改变者，它现在似乎工作但我仍有一个问题是，在查询结束时我无法找到如何在提交查询之前修剪它

这是代码

<?php
$host = "localhost";
$user = "root";
$pass = "123456";
$db = "generated";
$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!");
mysql_select_db($db) or die ("Unable to select database!"); 
$file = file('users.text'); # read file into array
$count= count($file);
if($count > 0) # file is not empty
{
    $milestone_query ="INSERT into `users`(`username`, `password`) values";
    $i = 1;
    foreach($file as $row)
    {
        $row = str_replace("\n", '', $row);
        $milestone = explode(' ',$row);
        $us= $milestone[0];
$requete ="SELECT `username` FROM `users` WHERE `username`='$us'";
$queryset=mysql_query($requete);
$row2 = mysql_fetch_assoc($queryset); 
$bood = $row2['username'];
if ($us == $bood)
{
  $i++;

}  else{
        $milestone_query .= "('$milestone[0]', '$milestone[1]')";
        $milestone_query .= $i < $count ? ',':'';

}

}
mysql_query($milestone_query) or die(mysql_error());
}
?>

这是查询结果

＆＃34;插入users（username，password）值（＆＃39; aspireupp7p＆＃39;，＆＃39; 97025407＆＃39;），（＆＃39; artre1r7pp＆＃39;，＆＃39; 40138199＆＃39;），（＆＃39; asuiozy4p＆＃39;，＆＃39; 44896449＆＃39;），（＆＃39; asuytrdiop＆＃39;，＆＃39; 36582797＆＃39;），＆＃34;

你看到最后我有这个，你能帮助我吗谢谢你

我已经清理了一点代码..祝你好运！

<?php

$host = "localhost";
$user = "root";
$pass = "123456";
$db = "generated";

$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!");
mysql_select_db($db) or die ("Unable to select database!");

$users = file('users.text'); # read file into array
if ($count = count($users)) # file is not empty
{

    $milestone_query = "INSERT into `users`(`username`, `password`) values";
    $milestone_query_count = strlen($milestone_query);

    foreach ($users as $i => $user) {
        $userInfo = explode(' ',trim($user));
        $username = current($userInfo);
        $password = next($userInfo);

        $requete = "SELECT `username` FROM `users` WHERE `username` ='{$username}'";
        if(!$result =boolval(mysql_fetch_assoc(mysql_query($requete)))){
            var_dump($username." added!");
            $milestone_query .= "('$username', '$password'),";
        }

    }

    $milestone_query = trim($milestone_query, ",");

    if(strlen($milestone_query) !== 50){
        mysql_query($milestone_query) or die(mysql_error());
        var_dump("finished!");
    }else{
        var_dump("No new users!");
    }

}
