Question

我正在尝试将CSV上传到表格。但是，密码是纯文本，我想在过程中转换为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);

Answer 1

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

以下程序将对第二列进行哈希处理。

<?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仅适用于PHP 5.5及更高版本。如果您在此之前运行版本并且无法升级，请使用crypt功能。

不要试图使用SHA-*或MD-*。

使用password_hash加载数据本地Infile
