我想很多人经常会用phpmyadmin进行数据的导入与导出,但是在很多使用虚拟主机的情况下,导出没什么问题但是导入就存在很大的问题了,我想这里我也不多说了站长都会

php 在线导入 mysql 大数据程序

"; //print_r($data); $data_new=array(); $tmp=array(); foreach ($data as $line) { $line=trim($line); if(strlen($line)==0){ continue; } if(substr($line,0,2)=='--'){ continue; } if(substr($line,0,2)=='/*'){ continue; } $tmp[]=$line; if(substr($line,-1)==';'){ $query=implode('',$tmp); $tmp=array(); $data_new[]=$query; } } $mysqli=new mysqli('localhost','root','root','test'); if($mysqli->connect_errno){ exit('数据库连接失败!'); } $mysqli->query("set names utf8"); $error=array(); foreach($data_new as $sql){ $mysqli->query($sql); $r=$mysqli->error; if($r) $error[]=$r; } print_r($r); /* mysql>ALTER TABLE tbl2 DISABLE KEYS; Query OK, 0 rows affected (0.00 sec) mysql>INSERT INTO tbl2 SELECT * FROM tbl1; Query OK, 2000000 row affected (36.30 sec) Records: 2000000 Duplicates: 0 Warnings: 0 mysql>ALTER TABLE tbl2 ENABLE KEYS; Query OK, 0 rows affected (44.55 sec) */

适用情况:phpmyadmin导出的sql文件过大,无法导入到线上phpmyadmin中

把该程序和sql文件上传到空间中,用完后删除即可。

分享一个其他网友的方法吧,,小伙伴们也可以参考下

$rate_info = file("$table.txt"); print $n_s = chop($rate_info[0]); for($start=1;$start { $value=""; for ($i=$start;$i

以上所述就是本文的全部内容了,希望大家能够喜欢。
