按位不起作用

Question

我正在使用其中一个脚本

<?php
$num1 = 33554432;
$num2 = 975827238;
if($num2 & $num1){
echo "Yes";
}else{
echo "No";
}
?>

问题是当它应该为no时它回应是,任何回应都会被赞赏

Answer 1

33554432 & 975827238是33554432,这不是零,所以不,它不应该是

  97582723810 = 1110100010100111110001001001102
&  3355443210 = 0000100000000000000000000000002
-----------------------------------------------
   3355443210 = 0000100000000000000000000000002
