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";
?>
