Suresh,

After you use array_unique() to remove duplicate values, can't you 
simply use sort() to impose consecutive keys?


http://php.net/sort :

This function sorts an array. Elements will be arranged from lowest 
to highest when this function has completed.


Note: This function assigns new keys for the elements in array. It 
will remove any existing keys you may have assigned, rather than just 
reordering the keys.

[PHP] Unique Array

[Deirdre Mc Cann]

Hi

Can anyone help me? I need to produce a random and uniques array using 
numbersbetween 0 and 9. I tried to create a random array and them make it 
unique.

for ($i = 0; $i100; $i++){
$a[$i] = rand(0,9);
$test=$a[$i];
}

$ra = array_unique($test);

I keep getting an error saying $test is the incorrect type. Can someone 
please explain why this doesn't work. And does anyone know how to get a 
unique and random array, every time the page is refreshed.

Thanks
Deirdre
