Hi all,
How we avoid the duplicate value during random number generation without using unique function

Hi,

If suppose you want to get the random numbers from 1 to 5 without any duplicates means,

PHP Code:

while ( $i < 5 )
{
    $rnd = rand(1,5);
    if( !isset($tmprnd[$rnd]) )
    {
        $tmprnd[$rnd] = 'set';
        echo $rnd."<br>";
        $i++;
    }    
} 


Hope it helps.
