mysql 使用 PHP 将服务器中的 table 复制到本地服务器

Question

我想用 PHP.

将服务器中的 table 数据复制到本地服务器

这是我的脚本

<?php

$h_local = "localhost";
$u_local = "root";
$p_local = "";
$db_local = "";


$h_server = "localhost";
$u_server = "root";
$p_server = "";
$db_server = "";

$server = new mysqli($h_server,$u_server,$p_server,$db_server);

$local = new mysqli($h_local,$u_local,$p_local,$db_local);

$result = $local->query("SELECT * FROM b_barang");

while ($row = $result->fetch_assoc()) {
  foreach ($row as $field => $value) {
    $fields .= "$field, ";
    $values .= "'$value', ";
  }
  // remove trailing ", " from $fields and $values
  $fields = preg_replace('/, $/', '', $fields);
  $values = preg_replace('/, $/', '', $values);

  $sql = "INSERT INTO b_barang ($fields) VALUES ($values)";
  $arr[] = $sql;

}


foreach($arr as $a){
    $server->query($a);
    echo $a."<br><br>";
}
?>

结果在第一个数组中，如

FIRST RESULT

INSERT INTO b_barang (Kode, Nama, Satuan, HP, PPN, Diskon, HJ, Kemasan, Margin, Saldo, TglPesan, Batmin, Batmak, HPAwal, PPNAwal, DiskonAwal, HJAwal, IsiKemasan, HPKemasan, HPKemAwal, HPPAverage, HPPAverageAwal, Jenis, HPP, HPPAwal, SaldoTemp, SaldoInput, Supplier) VALUES ('3', 'barang 3', '', '', '', '', '', '', '', '', '', '', '', '', '0', '', '0', '0', '0', '0', '', '', '', '', '', '0', '0', '')

下一个结果是错误的，就像从第一次结果中添加值一样

`SECOND RESULT`
INSERT INTO b_barang (Kode, Nama, Satuan, HP, PPN, Diskon, HJ, Kemasan, Margin, Saldo, TglPesan, Batmin, Batmak, HPAwal, PPNAwal, DiskonAwal, HJAwal, IsiKemasan, HPKemasan, HPKemAwal, HPPAverage, HPPAverageAwal, Jenis, HPP, HPPAwal, SaldoTemp, SaldoInput, SupplierKode, Nama, Satuan, HP, PPN, Diskon, HJ, Kemasan, Margin, Saldo, TglPesan, Batmin, Batmak, HPAwal, PPNAwal, DiskonAwal, HJAwal, IsiKemasan, HPKemasan, HPKemAwal, HPPAverage, HPPAverageAwal, Jenis, HPP, HPPAwal, SaldoTemp, SaldoInput, Supplier) VALUES ('3', 'barang 3', '', '', '', '', '', '', '', '', '', '', '', '', '0', '', '0', '0', '0', '0', '', '', '', '', '', '0', '0', '''1', 'barang1', '', '', '', '', '', '', '', '', '', '', '', '', '0', '', '0', '0', '0', '0', '', '', '', '', '', '0', '0', '')

如您所见，结果 2 中的值添加了结果 1 的值。

我该如何解决？

Answer 1

您需要做的就是每次在 while 循环中清除 $fields 和 $values 变量。当前，您正在将第二个查询添加到第一个查询，然后将第三个查询添加到第一个和第二个查询。等

while ($row = $result->fetch_assoc()) {

    // clear out these 2 variables before starting another iteration
    $fields = '';
    $values = '';

  foreach ($row as $field => $value) {
    $fields .= "$field, ";
    $values .= "'$value', ";
  }
  // remove trailing ", " from $fields and $values
  $fields = preg_replace('/, $/', '', $fields);
  $values = preg_replace('/, $/', '', $values);

  $sql = "INSERT INTO b_barang ($fields) VALUES ($values)";
  $arr[] = $sql;

}

您可能还想检查这个循环，因为它似乎是将 INSERTS 应用到服务器而不是本地数据库

foreach($arr as $a){
    // Should this line
    //$server->query($a);
    // be
    $local->query($a);
    echo $a."<br><br>";
}
