PHP中怎么使用password_hash()加密

//查看哈希值的相关信息array password_get_info (string $hash) //创建hash密码string password_hash(string $password , integer $algo [, array $options ]) //判断hash密码是否特定选项、算法所创建boolean password_needs_rehash (string $hash , integer $algo [, array $options ]  boolean password_verify (string $password , string $hash)//验证密码

$password = 'password123456';//原始密码$hash_password = password_hash($password, PASSWORD_BCRYPT);//使用BCRYPT算法加密密码if (password_verify($password , $hash_password)){   echo "密码匹配";}else{     echo "密码错误";}
