php check if array values are consecutive

Question

I have an array $dice (4,7,3,6,7)

I need a way of checking if each of the values in that array are consecutive numbers.

Is there an easy method of doing this?

Answer 1

try this:

$dice = array(4,5,2,6,7);
function checkConsec($d) {
    for($i=0;$i<count($d);$i++) {
        if(isset($d[$i+1]) && $d[$i]+1 != $d[$i+1]) {
            return false;
        }
    }
    return true;
}
var_dump(checkConsec($dice)); //returns false
var_dump(checkConsec(array(4,5,6,7))); //returns true
