php生成rss文件求改进
我写了一个php利用DOMDocument 组件生成rss文件的代码,但是感觉太过于臃肿,想封装成一个类但是一直没成功,特来请教
生成后rss大体是这样的





1123木头
1
http://www.xxx.com
id:1,user_name:,pass:123,real_name:木头




2456小木头
2
http://www.xxx.com
id:2,user_name:,pass:456,real_name:小木头





当然代码太过于冗余



$doc = new DOMDocument('1.0','utf-8');
$doc->formatOutput = true;


//创建标签
//创建rss标签
$rss = $doc->createElement('rss');
//创建channel下面的标签
$channel         = $doc->createElement('channel');
$ctitle         = $doc->createElement('title');
$clink             = $doc->createElement('link');
$cdescription     = $doc->createElement('description');






foreach ($arr as $key => $val) {
    //创建item标签
    $item             = $doc->createElement('item');
    //创建item下的子标签标签
    $user             = $doc->createElement('user');
    $ititle         = $doc->createElement('title');
    $ilink             = $doc->createElement('link');
    $idescription     = $doc->createElement('description');
    //创建user标签
    $user_id         = $doc->createElement('user_id');
    $user_name         = $doc->createElement('user_name');
    $user_pass         = $doc->createElement('user_pass');
    $real_name         = $doc->createElement('real_name');
    /*这里是需要数据库循环调用的地方*/
    //创建内容
    //创建item下面的标签的内容
    $c_ititle = $doc->createTextNode($val['user_id']);
    $c_ilink = $doc->createTextNode('http://www.xxx.com');
    $c_idescription = $doc->createTextNode('id:'.$val['user_id'].',user_name:'.$val['user_name'].',pass:'.$val['pass'].',real_name:'.$val['real_name']);
    //创建user下面的标签的内容
    $c_user_id        = $doc->createTextNode($val['user_id']);
    $c_user_name     = $doc->createTextNode($val['user_name']);
    $c_user_pass     = $doc->createTextNode($val['pass']);
    $c_real_name     = $doc->createTextNode($val['real_name']);
    //创建item属性值
    $a_id = $doc->createTextNode($val['user_id']);


    //创建属性
    $attributes = $doc->createAttribute('id');
    /*这里是需要数据库循环调用的地方*/
    //item一级标签的元素内容继承
    $ititle->appendChild($c_ititle);
    $ilink->appendChild($c_ilink);
    $idescription->appendChild($c_idescription);
    //user一级标签的元素内容继承
    $user_id->appendChild($c_user_id);
    $user_name->appendChild($c_user_name);
    $user_pass->appendChild($c_user_pass);
    $real_name->appendChild($c_real_name);
    /*这里是需要数据库循环调用的地方*/
    //继承
    $channel->appendChild($item);
    //item一级标签的标签继承
    $item->appendChild($user);
    $item->appendChild($ititle);
    $item->appendChild($ilink);
    $item->appendChild($idescription);
    //id=1
    $attributes->appendChild($a_id);
    //
    $item->appendChild($attributes);


    //item一级标签的标签继承
    $user->appendChild($user_id);
    $user->appendChild($user_name);
    $user->appendChild($user_pass);
    $user->appendChild($real_name);
}

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

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),
