代码中的错误

代码（字符串）结果['密码'] 丢失 $
code $ result ['password'] = $ stmt7-＆gt; fetch（PDO :: FETCH_OBJ）; 表示将对象分配给数组中名为 password 的元素命名结果
PDO :: FETCH_OBJ 表示你得到的是一个对象，而不是一个数组

更新您发布的问题

$result['password'] = $stmt7->fetch(PDO::FETCH_OBJ);
$con5->commit();
if(password_verify($secpass,(string)result['password'])

到

$result = $stmt7->fetch(PDO::FETCH_OBJ);
$con5->commit();
if(password_verify($secpass,(string)$result->password)

再试一次

password_verify函数inxampp php mysql不能正常工作
