[Resolved] searching for NUMERIC values in an array

[perpetualshaun]

Okay... I'm passing an array of variables called $add_qty to my page. Is there a way to manipulate the in_array command to look for:

1) At least ONE value in the array at all, and
2) That all the values passed are numeric?

I know that I can use the is_numeric thing on each value if I loop through all the values in the array, but I'm wondering if there is another way to do it?

Thanks,

Shaun

not really, that's what i would do:

$array = array(1,2,3,4,5,6,7,8,9);

if (!count($array)) {echo 'the array has 0 indexes<br>';}
foreach ($array as $key => $value)
{
	if (!is_numeric($value)) {echo 'index #' . $key . ' is not numeric';}
}

Maybe, if that's all you really want...

if(count($array) > 0) {
   if(is_numeric(implode('', $array)))
      echo 'All is good';
   else
      echo 'Not all values are numeric';
}
else
   echo 'No array elements';

if(count($array)==0) echo 'empty array';
elseif(array_filter($array,'is_numeric')!=$array) echo 'Not all numeric';
else echo 'numeric-only array';
