which way will be faster ?

[miz]

ok like its like that

i got table with id,name,info,info,and,more,info

heh

now this table will be bigger and bigger with the time
can be more then 70000 rows
can be on 5000

so i thought to make new dir
with ids

empty file that will be like 55214.txt
file size : 0bytes

then in php do

PHP Code:

if (file_exsits("ids/55214.txt")
{
//query to get info from id 55214
//echo info
} else {
echo " Not Found";
} 


way 2 :

PHP Code:

$bla = selcet * from table where id=$id
if (!$bla) {
echo " Not Found";
} else {
//show info
} 


which way will be faster ??
