使用password_hash加载数据本地Infile - Load Data Local Infile with password_hash

Load Data Local Infile with password_hash

我正在尝试将CSV上传到表中。然而，密码是纯文本的，我想在这个过程中将其转换为password_hash。请帮忙。

$sql = "LOAD DATA LOCAL INFILE '".$mylfile."'
   INTO TABLE parentstudent
   FIELDS TERMINATED BY ','
   OPTIONALLY ENCLOSED BY ''"' 
   LINES TERMINATED BY ''n' 
   IGNORE 1 LINES 
   (parentstudent_id, @parent_id, student_id, school_id)
   set parent_id =".password_hash."'(parent_id,".PASSWORD_DEFAULT.")";
$con=mysqli_connect("localhost","root","","confapp");
$result = mysqli_query($con, $sql);

假设有一个名为clearpwords.csv的文件，其内容如下：

1,test,1,1
2,testtest,2,1

下面的程序将散列第二列。

<?php
// this is needed for any significant number of inputs to password_hash()
set_time_limit(0);
$infile = "clearpwords.csv";
$myfile = "hashedpwords.csv";
$reader = fopen($infile, 'r');
$writer = fopen($myfile, 'w');
$buffer = '';
while ($line = fgetcsv($reader)) {
    $line[1] = password_hash($line[1], PASSWORD_DEFAULT);
    $buffer .= implode(',', $line) . "'n";
    if (strlen($buffer) > 1024) {
        fwrite($writer, $buffer);
        $buffer = '';
    }
}
fwrite($writer, $buffer);
fclose($reader);
fclose($writer);

它将创建一个名为myfile.csv的文件，如下所示。

1,$2y$10$KwG1S4w7T4ov71bFSsKhlOW2CpFrMurtZRz3az94o7BX70pmohCb.,1,1
2,$2y$10$zQkH5vDIYLCqkUxxaqH6nuZ67fXj71XiBVjxztvst.dtvSlFqjDou,2,1

您现在可以在myfile.csv 上运行脚本

$sql = "LOAD DATA LOCAL INFILE '".$mylfile."'
        INTO TABLE parentstudent
        FIELDS TERMINATED BY ','
        OPTIONALLY ENCLOSED BY ''"' 
        LINES TERMINATED BY ''n' 
        IGNORE 1 LINES 
        (parentstudent_id, @parent_id, student_id, school_id)";
$con = mysqli_connect("localhost", "root", "", "confapp");
$result = mysqli_query($con, $sql);

请注意，password_hash仅在PHP 5.5及更高版本中可用。如果您运行的是在此之前的版本，并且升级不是一个选项，请使用crypt函数。

不要试图使用SHA-*或MD-*。
