php: '0' as a string with empty()

Question

I want a 0 to be considered as an integer and a \'0\' to be considered as a string but empty() considers the \'0\' as a string in the example below,

$var = \         


        

Answer 1

if ( (is_array($var) && empty($var)) || strlen($var) === 0 ) { echo $var . ' is empty'; }
