sql文件怎么用php导入到数据库

$file_name = "d:test.sql";
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "123456";
$dbname = "test";
set_time_limit(0);
$fp = @fopen($file_name,"r") or die("sql文件打不开");//打开文件
$pdo = new PDO("mysql:host=localhost;dbname=test","root","123456");//连接数据库
$pdo->query('set names utf8');//设置编码
echo "正在执行导入操作";
while($SQL = GetNextSQL()){
if(!$pdo->query($SQL)){
echo "执行出错";
echo "SQL语句为".$SQL;
}
}
echo "导入完成";
fclose($fp) or die("can't close file");//关闭文件
mysql_close();
//从文件中逐条取sql
function GetNextSQL(){
global $fp;
$sql="";
while($line = @fgets($fp,40960)){
$line = trim($line);
$line = str_replace("////", "//", $line);
$line = str_replace("/","'",$line);
$line = str_replace("//r//n","chr(13).chr(10)",$line);
$line = stripcslashes($line);
if(strlen($line)>1){
if($line[0]=='-' && $line[1]=="-"){
continue;
}
}
$sql .= $line.chr(13).chr(10);
if(strlen($line)>0){
if($line[strlen($line)-1]==";"){
break;
}
}

}
return $sql;
}
亲测有效。。
