mysql表utf8编码,内容gbk编码的乱码转换

标签：

今天遇到一个数据库库是utf8，表也是utf8，但内容是gbk的问题，出现了中文乱码

第一步  先把所有的表copy一份，比如表名叫 user，copy一份光表结构的，叫user2；

第二步  把表中的数据转码后插入表2的表中

<?php
header("Content-type: text/html; charset=utf-8");        

function get_sql($tablename){
	$con = mysql_connect("localhost","root","root");
	if (!$con) die(mysql_error());

	mysql_select_db("bfwl",$con);
	mysql_query("set names ‘utf-8‘"); 

	$result = mysql_query("select * from ".$tablename." ");

	$txt = "";

	while($row = mysql_fetch_array($result)){
		$sql = "";
		foreach($row as $k=>$v){
			if(!is_numeric($k)){
				$v = iconv("GBK", "UTF-8", $v);
				$v = str_replace("\r\n", "<br>", $v);
				$v = trim($v);
				$v = str_replace("‘", "“", $v);
				$v = str_replace(‘"‘, "”", $v);
				$sql .= "$k=‘$v‘,";
			}
		}
		$sql = trim($sql,",");	
		$sql = "INSERT INTO ".$tablename."2 SET ".$sql.";\r\n";
		excute($sql);
		$txt .= $sql;
	}
	//file_put_contents("sql/".$tablename.".sql", $txt);	
}

function excute($sql){
	$con = mysql_connect("localhost","root","root");
	if (!$con) die(mysql_error());
	mysql_select_db("bfwl",$con);
	mysql_query("set names utf8"); 
	mysql_query($sql);
	mysql_close($con);
}

//每个表来一次
get_sql("bingzhongbiao");
get_sql("chat_record");
get_sql("juesebiao");
get_sql("meitibiao");
get_sql("net_chz");
get_sql("net_xf_biao");
get_sql("yishengbiao");
get_sql("yiyuanbiao");
get_sql("yonghubiao");
get_sql("zaixian");
get_sql("zhanzhang");
