将每个数组放入 SQL 查询中

Question

问题：

将从文本文件生成的每个数组放入 SQL 查询中。我有一个包含此类机场信息行的文本文件：https://abc-supervisor.c9users.io/airports.txt

如果您不想点击链接，这里有一个示例：

1,"Goroka","Goroka","Papua New Guinea","GKA","AYGA",-6.081689,145.391881,5282,10,"U","Pacific/Port_Moresby"
2,"Madang","Madang","Papua New Guinea","MAG","AYMD",-5.207083,145.7887,20,10,"U","Pacific/Port_Moresby"
3,"Mount Hagen","Mount Hagen","Papua New Guinea","HGU","AYMH",-5.826789,144.295861,5388,10,"U","Pacific/Port_Moresby"

我正在尝试将每个值放入 SQL 表中。

PHP：

<?php
    $lines = file('airports.txt');

    echo '<xmp>';

    $airport = array();

    foreach($lines as $row) 
    {
      $airport = str_replace('"', '', explode(",", $row));
      print_r($airport);
    }

    echo '</xmp>';
?>

输出：

Array
(
    [0] => 1
    [1] => Goroka
    [2] => Goroka
    [3] => Papua New Guinea
    [4] => GKA
    [5] => AYGA
    [6] => -6.081689
    [7] => 145.391881
    [8] => 5282
    [9] => 10
    [10] => U
    [11] => Pacific/Port_Moresby

)
Array
(
    [0] => 2
    [1] => Madang
    [2] => Madang
    [3] => Papua New Guinea
    [4] => MAG
    [5] => AYMD
    [6] => -5.207083
    [7] => 145.7887
    [8] => 20
    [9] => 10
    [10] => U
    [11] => Pacific/Port_Moresby

)

期望的输出：

将每个值插入 SQL 中的一行。谢天谢地，如果有人能指出正确的方向。

Answer 1

我假设您想读取 CSV 文件并将每一行加载到数据库表的一行中。

如果 MySQL 服务器可以访问该文件，则使用 LOAD DATA INFILE 是最简单的方法。像这样的东西（未经测试，不是我经常使用的东西）

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

$mysqli->query("LOAD DATA INFILE 'airports.txt' 
                INTO TABLE expenses  
                    FIELDS TERMINATED BY ',' 
                           OPTIONALLY ENCLOSED BY '\"'
                    LINES  TERMINATED BY '\\n' 
                (col0, col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11)");

但假设您可能希望事先对某些值进行一些其他处理，或者无法从 MySQL 访问该文件，那么您可能只想手动插入每一行（请注意，您可以插入多行一次会更有效率，但这是一个单独的问题）。

<?php

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

if (($handle = fopen('airports.txt', "r")) !== FALSE) 
{
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
    {
        if ($stmt = $mysqli->prepare("INSERT INTO some_table(col0, col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11) VALUES(?,?,?,?,?,?,?,?,?,?,?,?)")) {
            $stmt->bind_param("isssssddiiss", $data[0], $data[1], $data[2], $data[3], $data[4], $data[5], $data[6], $data[7], $data[8], $data[9], $data[10], $data[11]);
            $stmt->execute();
        }   
    }
    fclose($handle);
}

Answer 2

json 编码存储在数据库中

foreach($lines as $row) 
{
  $airport = str_replace('"', '', explode(",", $row));
  $json = json_encode($airport );
  //Code to store $json in database
}

当您检索数据时，您可以使用 json_decode 对其进行解码。

if you want to store field wise you can do this

    foreach ($airport as $key => $field) { 
      for($i=0;$i<11;$i++){
       if($key == 'i') {
         $value[$i] = $field; }

    $sql = "INSERT INTO table name (fields1,fields2,...) values ($value[0],$value[1]...); }

Answer 3

foreach ($airport as $key => $value)
   {
     $sql = "INSERT INTO table name (fields1,fields2,...) values    ($value[0],$value[1]...)
   }
