PHP的结果集和ASP的记录集就只是叫法上的不同吗

Jun 23, 2016 pm 02:16 PM

我觉得PHP的结果集和ASP的记录集是一样的,它们都是内存中的一个虚表,都有一个指针指向当前记录。

就只在它们上面有些操作不同而已

PHP
每次输出记录后记录集指针可自动向下移动一条,结果集可自动关闭
ASP
需要手动使用rs.movenext将记录集指针移动到下一条,记录集必须手动关闭
ASP有BOF和EOF属性,PHP没有

不知我理解得对不对,希望大家能够补充或纠正哦

怎么没有人对这个帖子感兴趣吗

记录集 RecordSet 是 ADODB 的一个组件
结果集 result 是一个资源号
虽然两者都代表查询的结果,但他们是完全不同的两个东西

但是从实现的功能上看,它们基本是一样的吗

两个资源的类型不一样,但是实现的功能一样
php 的mysql_fetch_array,就是移动
参考如下代码
$result = mysql_query("SELECT id, name FROM mytable");

    while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
        printf ("ID: %s  Name: %s", $row[0], $row[1]);
    }

但是从实现的功能上看,它们基本是一样的吗
从实现的功能上看,基本一样。都是循环取结果集数据。

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
