Random Number

[princeofpersia]

Hi Guys

 

I have a code what inserts very simple queries to database, im trying to add a random reference number for each enrty using

$reference = rand(111111111111,999999999999);

 

but each time I add an entry it gives me the same random number previously generated for previous entry

 

can you help pleasE?

Try:

 

mt_srand((double)microtime()*1000000);
$reference = mt_rand(111111111111,999999999999);

If you say you are putting multiple entries into the database, I presume you are using some kind of loop, if so is $reference set inside or out of the loop? :-)

yeah, i have solved it, I have changed the number

from

$reference = rand(111111111111,999999999999);

 

to

 

$reference = rand(11111111,99999999);

 

so less digits and it work fine, im not using loop but I have tried it few times and now it gives me different reference numbers each I add an entry,

 

thanks for you time guys
