我们对数据库进行迁移的时候,用的一般都是mysqldump 或是phpmyadmin
先把某个表的数据倒出到一个 SQL 文件中,然后再用mysql 等工具来执行,以下的例子说明了如何从 SQL 文件中读出并结合成SQL语句,再上传到远和机器上去执行,免去了事先上传的麻烦。供各位参考。
<html>
<?php
$hostname="localhost";
$dbname ="dbname";
$username = "username";
$pass = "password";
mysql_pconnect($hostname, $username, $pass);
mysql_select_db($dbname);
}
?>
<head>
<title>dump datas</title>
</head>
<body>
<form name="form1" >
</form>
<?
if ($go)
{
echo " dumping data please waiting............................<BR>";
echo "your sql file:".$file_name_name."<br>";
$success=true;
$fp=fopen($file_name,"r");
$qu ='';
while ($str_len =fgets($fp,256))
{ $len=strlen($strlen);
if (substr($str_len,0,1)!="#")
{ $qu.=$str_len;
if (substr($str_len,0,4)=="DROP")
{
//echo $str_len;
$qu=substr($qu,0,strlen($qu)-2);
//echo $qu." afdf";
$re=mysql_db_query($dbname,$qu) or die(mysql_error().$qu);
if ($re) echo "drop ing table ... ...<br>"; else $success=false;
$qu="";
}
$sub_b=strlen($str_len)-4;
if (substr($str_len,strlen($str_len)-4,2)==");")
{
$qu=substr($qu,0,strlen($qu)-2);
$re=mysql_db_query($dbname,$qu) or die(mysql_error().$qu);
if ($re) echo "inserting... ...<BR>"; else $success=false;
$qu="";
