php 在线导入 mysql 大数据程序
<?php header("content-type:text/html;charset=utf-8"); error_reporting(E_ALL); set_time_limit(0); $file='./test.sql'; $data=file($file); echo "<pre>"; //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<($start+$n_s-1);$i++) { $tmp = str_replace("&&jimmy&&"," ",chop($rate_info[$i])); $value .= "'".addslashes($tmp)."',"; } $tmp = str_replace("&&jimmy&&"," ",chop($rate_info[$start+$n_s-1])); $value .= "'".$tmp."'"; $query = "insert into $table values (".$value.")"; print mysql_error(); mysql_query($query); print $start." "; } print "ostart"; ?>
