PHP实现导入大SQL文件
对于mysql的大量数据导入导出,直接在服务器上使用命令,会很方便快捷,但是有时候我们不能总结直接调用命令来实现,此时我们可以使用一个脚本语言作为调用这个命令的中介,这里我是用的是php里面的system函数。 system使用说明: string? system ?(?string?
对于mysql的大量数据导入导出,直接在服务器上使用命令,会很方便快捷,但是有时候我们不能总结直接调用命令来实现,此时我们可以使用一个脚本语言作为调用这个命令的中介,这里我是用的是php里面的system函数。
system使用说明:
string?system?(?string?$command
?[,?int?&$return_var
?] )
command: 执行的命令
return_var: 如果return_var存在,则为执行命令完后返回的结果
函数返回的结果为命令输出的最后一行。
举例:
<?php // Outputs all the result of shellcommand "ls", and returns // the last output line into $last_line. Stores the return value // of the shell command in $retval. $last_line = system('ls', $retval); // Printing additional info echo 'Last line of the output: ' . $last_line; echo 'Return value: ' . $retval; ?>
所以如果需要通过php导入大数据,可以使用:
<?php system( "mysql -hDbhost -uDbuser -pPassword Dbname < backup.sql" ); print "导入成功" ; ?>
Dbhost 改为您的数据库服务器地址
Dbuser 改为您的数据库用户名
Password 改为您的数据库用户密码
Dbname 改为您的数据库名
backup.sql 导入的sql文件
3.在浏览器里面访问mysql.php即可完成导入,同理如果需要导出sql语句也可以使用system命令来完成,其执行的时间相对比较快。
