网上关于PHP BOT程序的实例还是很少的,前段时间也是业务需求,开始接触此类程序,很有意思。所谓BOT实际上是模拟GET或POST,去action一些程序,实现一些自动化处理,当然这个东西是双刃剑,可别使坏就好。
PHP实现BOT有多种方式,个人比较喜欢HttpRequest,一来比较OO,而来编写简单方便。以下是class对应的function,还有一些examples。
function可以直接点击进入PHP官方的API,有意的朋友进去逛逛;方法名称很直观,不多解释。。
Example #1 GET example
代码
<p class="sycode"> <? php $r = new HttpRequest( ' http://example.com/feed.rss ' , HttpRequest :: METH_GET); $r -> setOptions( array ( ' lastmodified ' => filemtime ( ' local.rss ' ))); $r -> addQueryData( array ( ' category ' => 3 )); try { $r -> send(); if ( $r -> getResponseCode() == 200 ) { file_put_contents ( ' local.rss ' , $r -> getResponseBody());}} catch (HttpException $ex ) { echo $ex ;} ?> </p>
这个example模拟get去请求一个rss订阅器,还addQueryData这样的GET查询参数,然后执行send,发送此GET请求当getResponseCode是200时,也就是BOT成功时,把get请求返回的response的html存入本地的文件中。
Example #2 POST example
代码
<p class="sycode"> <? php $r = new HttpRequest( ' http://example.com/form.php ' , HttpRequest :: METH_POST); $r -> setOptions( array ( ' cookies ' => array ( ' lang ' => ' de ' ))); $r -> addPostFields( array ( ' user ' => ' mike ' , ' pass ' => ' s3c|r3t ' )); $r -> addPostFile( ' image ' , ' profile.jpg ' , ' image/jpeg ' ); try { echo $r -> send() -> getBody();} catch (HttpException $ex ) { echo $ex ;} ?> </p>
这个example模拟POST去请求一个PHP文件,POST不是通过addQueryData这样的function,而是通过addPostFields来设置模拟的输入表单,然后执行send,把POSt请求返回的response的html echo到PHP当前页面中。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
