PHP how to count the arrays values?

Question

I'm trying to count all the values in the array and check if one value was entered and if so display a certain message for it and if there was more then one value entered display a different message for it.

How will I be able to this and where should I add it to my code?

Here is the code below.

if ($array == 1){
    echo $array . " has been entered";
} else {
    echo implode(", ", $array) . " have been entered";
}

note that the check is actually redundant in this case as implode with an array of size 1 will give the desired result also. Just replace the whole thing with echo implode(", ", $array) . " have been entered"; and skip the check. — Esben Skov Pedersen

if (count($array) == 1){
        echo $array[0] . " has been entered";
} else {
        echo implode(", ", $array) . " have been entered";
}

sizeof() also does the same thing, if you prefer writing sizeof instead of count.

sizeof is just an alias to count.

count($array) gives you number of elements in the array
