今天犯2了 当永记 PHP TRUE == 2

今天同事测试 投票功能 始终报已投过票的提示,仔细检查了下代码,也没有发现问题出在哪里?

?

最后一行行的排查才发现 原来是 bool == 整数 这个问题

?

$str=" ";

var_dump( empty($str)? );

exit;

?


$str = "1";
var_dump($str[0]);
$str = implode('|',$str);
//var_dump($str);


exit;

$a = 1==1;
$b = 2 == $a;

var_dump($b);
br( "\$b = " . $b );

var_dump(TRUE == 2);


exit;
