据说很多框架不用写sql语句,仅凭封装就能调用数据表的字段,这个是怎么实现的,不可思议啊,因为传统的教程都说,不通过sql语句无法操作数据库啊,这到底是怎么 回事
拒绝那种发百度里的文章的帖子。要有自己的看法
回复讨论(解决方案)
这个很好实现
写个php类 把数据库操作语句写到这个类里
然后传参调用,不知我说明白没有
类里面的各个函数代表不同的操作。
把最基础的操作拆开封装成类后直接OOP调用即可。

能举一个例子吗,比如select 这一数据库查询语句的功能,如何封装呢,简单写写意思就行,我不想了解细节,只想了解大概!
大多 php 框架都在一定程度上模拟了 ORM (对象关系映射,一种概念性的、易于理解的模型化数据的方法)的实现,但最终是翻译成 sql 指令执行的

这么 说最终还是要靠sql语句执行命令吗?能写一个翻译的句子看一下吗,简单点,只是稍微了解一下。
当然了,框架中的方法也是封装好的。归根结底,也是要执行SQL的。
function select($table,$field_array){ $field = implode(',', $field_array); $r = mysql_query("select $field from $table"); return $r;}
上面是一个简单的例子,完美的写法应该写成类,具体可以网上找下例子。
楼上取的例子好漂亮啊

The PHP Client URL (cURL) extension is a powerful tool for developers, enabling seamless interaction with remote servers and REST APIs. By leveraging libcurl, a well-respected multi-protocol file transfer library, PHP cURL facilitates efficient execution of various network protocols, including HTTP, HTTPS, and FTP. This extension offers granular control over HTTP requests, supports multiple concurrent operations, and provides built-in security features.

Laravel provides concise HTTP response simulation syntax, simplifying HTTP interaction testing. This approach significantly reduces code redundancy while making your test simulation more intuitive. The basic implementation provides a variety of response type shortcuts: use Illuminate\Support\Facades\Http; Http::fake([ 'google.com' => 'Hello World', 'github.com' => ['foo' => 'bar'], 'forge.laravel.com' =>
