php 在線導入 mysql 大數據程序

<?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('數據庫連接失??！');

}

$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);

/*

適用情況：phpmyadmin導出的sql文件過大，無法導入到線上phpmyadmin中

把該程序和sql文件上傳到空間中，用完后刪除即可。

分享一個其他網友的方法吧，小伙伴們也可以參考下

$rate_info = file("$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";

?>
