Check if an array contains empty values

[guvenck]

I send a form via POST method, the form contains an uncertain number of fields, so I use an array (let's say email[]). After sending the form, I would like to check if the array contains empty values. Naturally,

if($_POST['email'] == "") does not work even if all the fields are empty. So, I use a foreach loop to check if the array contains empty values:


$email = $_POST['email'];
foreach ($email as $key => $value){
if ($email[$key] == ""){
echo "field contains empty value";
}
}


is there any other way to check if all the items in an array contain empty values?

you can use the empty() function. It returns true or false.

If the only thing that counts as empty is the empty string:


echo (in_array('', $array)) ? 'has empt(y|ies)' : 'no empties';

This does not work:


if(empty($_POST['Email'])) {
echo "array is empty";
}

What if I want to check if the whole array is empty?

TMTOWTDI, but:


echo (current($array) == '' && count(array_unique($array)) == 1) ? 'all empty' : 'not empty';
