Question

我遇到错误：

您的SQL语法有错误；检查手册对应于您的MariaDB服务器版本，以使用正确的语法附近'（'10 .22.227.175'，'0'）（'10.22.227.49'，'0'）（'10.22.229.88'，'2 '）（'192.168.2'行

这是我的php代码：

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 


$file = file('MyLogFile.log'); # read file into array
$count = count($file);
if($count > 0) # file is not empty
{
    $sql = "INSERT into `ping`(`ip`,`fs`) values";
    foreach($file as $row)
    {
        $ping = explode(',',$row);
        $sql .= "('$ping[0]','$ping[1]')";

    }
    if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
} else {
     echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);


}

这是我的mylogfile.log *

10.22.227.254,0 
10.22.227.175,0 
10.22.227.49,0 
10.22.229.88,2
192.168.200.55,2 
10.22.227.155,0

我的MYSQL数据库是

id  int(11)  AUTO_INCREMENT

ip  text  latin1_swedish_ci 

fs  text  latin1_swedish_ci 

pid  text  latin1_swedish_ci 

dt  datetime

最重要的是：您的查询对SQL Injection相关的攻击开放。请学习如何使用Prepared Statements。

现在，您在Value子句中的不同行之间缺少逗号。如果要插入多行，则Insert Syntax为：

INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name
    [PARTITION (partition_name [, partition_name] ...)]
    [(col_name [, col_name] ...)]
    {VALUES | VALUE} (value_list) [, (value_list)] ...
    [ON DUPLICATE KEY UPDATE assignment_list]

您可以执行以下操作：

if($count > 0) # file is not empty
{
    // a counter variable to determine if this is first row of values
    $counter = 1;

    $sql = "INSERT into `ping`(`ip`,`fs`) values ";
    foreach($file as $row)
    {
        $ping = explode(',',$row);

        // if it is more than first row, add a comma separator
        if ($counter > 1) 
             $sql .= ' , ';

        $sql .= "('$ping[0]','$ping[1]')";

        // increment the counter
        $counter++;

    }
    if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
} else {
     echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
