$test=1;
echo gettype($test);
if(settype($test,"integer")==$test) echo "equal";
else echo "different";
output: integer equal
---------------------------------------------------
$test=0;
echo gettype($test);
if(settype($test,"integer")==$test) echo "equal";
else echo "different";
output: integer different
Why 0 is not an integer ?
