The sql exported by phpmyadmin is handed over to the php program and imported into other libraries. How to achieve this? This article provides a good method for everyone. Friends in need can take a look.

The complete code is as follows.

<?php
//导入phpmyadmin导出的sql数据
//整理 bbs.it-home.org
//$file表示通过读取sql文件返回的字符串,比如$file2=file_get_contents('db.sql');

function import($file2){
$Db = new Db();
$file2=explode("\n",$file2);//将文件内容按行读入到数组

$c1=count($file2);
for($j=0;$j<$c1;$j++)
{
$ck=substr($file2[$j],0,4);//取每行的前4个字符
if( ereg("#",$ck)||ereg("--",$ck) )//去掉注释
{
continue;
}
$arr[]=$file2[$j];//将去掉注释的文件内容按行读入数组$arr,数组每个元素对应一行
}
$read=implode("\n",$arr); //重新组织文件内容到一个字符串,(按照原来分好的一行一行的)
$sql=str_replace("\r",'',$read);//去掉"\r(回车符)"

$detail=explode(";\n",$sql);
//将经上述整理过的文件内容再次按一条完整的sql语句(以;和\n分隔)导入到数组$detail,
//此时数组detail的每个元素对应一条完整的sql语句
$count=count($detail);
for($i=0;$i<$count;$i++)
{
$sql=str_replace("\r",'',$detail[$i]);//去掉每行sql中的回车符
$sql=str_replace("\n",'',$sql);//去掉换行符
$sql=trim($sql);//去掉前后空格
//现在的$sql
$Db->query($sql);
}
}
?>
