Re: [PHP] check if any element of an array is not "empty"

hi,
as a result of one calculation I'm receiving an array where elements
could be 0 or date (as string yyyy-mm-dd hh:ii:ss).
I have to check if any of elements of the array is "date" or if all
elements of the array is 0?

If I try array_sum($result) I'll get 0 no matter what (0 + $string = 0).

I know I can do something like:
foreach($result as $value)
{
if ($value !=0)
{
$alert = true;
}
}

or

if (in_array($result, '-'))
{
$alert = true;
}


but I was thinking if there is the function does that.


i don think theres a function for that; and to be performance conscience, if
just one occurrence of a date is all you need to know its not all 0's then
break out of the loop once youve found that.

foreach($result as $value)
{
if ($value !== 0)
{
$alert = true;
break;
}
}
