PHP Check of SQL query for value quantities -

i have script checking values in database. there 3 instances need check for.

1) no value present 2) single value exists 3) multiple values exist

currently, have following script run first instance:

if($value){ echo ‘this showing if value exists’; }else{ echo ‘this showing if no value exists’; }

how can add check if array of values exist?

we need see code retrieves data, if have array of data use count:

if (count($value) > 1) {     // multiple values }

you may using select count in case can compare value:

if ($value["count"] > 1) {

And
