Empty Array

[Anon]

Hi!

How can I test if all values in an array are empty?

Thanks for tips!

the count() function will tell you if there are no indecies the array but if you just want to check to see the values are empty:

<?
function check_empty ($array) {
$empty = true;
foreach ($array as $value) {
if ($value) {$empty = false;}
}
return $empty;
}

$array = array (
'1' => '',
'2' => '',
'3' => '',
'4' => '',
'5' => ''
);

if (check_empty ($array)) {echo 'This array has all empty values';}
else {echo 'This array has at least one non-empty value';}
?>

You can speed that up a touch (on average, by a factor of 2) by adding "break;" immediately after the "$empty = false;" - once it becomes false it's never gonna become true again, so why keep searching?
