rand

[asmith]

$a = rand(1,100)

 

is that possible i delete the number of $a from range of the rand ?

for example

 

$a= rand(1,100)
$b = rand (1,100) // here min 1 , max 100 , but not including $a  
$c = rand(1,100) // here min1 , max 100 , but without $a and $b

Actually what do you mean ?

 

int rand ( [int min, int max] )

 

If called without the optional min, max arguments rand() returns a pseudo-random integer between 0 and RAND_MAX. If you want a random number between 5 and 15 (inclusive), for example, use rand (5, 15).

sorry i said it wrong .

i don't want rand give me repeated numbers :

 

$a = rand(1,100)

$b = rand(1,100)
while ($b == $a)
{$b = rand(1,100)}

 

that ! i was wondering maybe a specific function it has ?  and i don't need to code for that like above . it has ?

(then again  , it delete the $a from the range of the rand  , if $a was 13, then it get rand (1,100) , but without 13 included in that range,  that i don't have to check for being repeated)
