我的基本思路是遍历数组 判断当前元素有没有名为"childs"的子数组 如果有的话 递归执行本函数
$config = array( 'root' => array( 'childs' => array( 'body' => array( 'childs' => array( 'scroller' => array( 'childs' => array( 'header' => array( 'childs' => array( 'simpleHeader' => array( 'childs' => array( 'a' => array() ) ) ) ), 'items' => array( 'childs' => array( 'fuck' => array( 'childs' => array( 'b' => array() ) ) ) ) ) ) ) ) ) ));header("Content-type:text/xml;Charset=UTF-8");$xml = new XMLWriter();$xml->openUri('php://output');$xml->startDocument('1.0', 'UTF-8');$xml->setIndent(true);function writeXml($array){ global $xml; foreach($array as $key => $value){ $xml->startElement($key); if( isset($value['childs']) && is_array($value['childs']) && count($value['childs']) > 0 ){ writeXml($value['childs']); } $xml->endElement(); } $xml->endDocument(); $xml->flush();}writeXml($config);
为什么生成的xml不对? items跑到了外面 如图
回复讨论(解决方案)
if 判断的逻辑问题,你再仔细看看
php SPL里面有递归器,写起来简单点
把
$xml->endDocument();
$xml->flush();
移出 writeXml 函数,最后执行
....writeXml($config);$xml->endDocument();$xml->flush();
把
$xml->endDocument();
$xml->flush();
移出 writeXml 函数,最后执行
....writeXml($config);$xml->endDocument();$xml->flush();
感激不尽 我一直以为逻辑有问题 纠结了半天 结果问题居然出在这
整体封装成函数
function writeXml($array, $xml=null){ if(! $xml) { header("Content-type:text/xml;Charset=UTF-8"); $xml = new XMLWriter(); $xml->openUri('php://output'); $xml->startDocument('1.0', 'UTF-8'); $xml->setIndent(true); writeXml($array, $xml); $xml->endDocument(); $xml->flush(); }else { foreach($array as $key => $value){ $xml->startElement($key); if( isset($value['childs']) && is_array($value['childs']) && count($value['childs']) > 0 ){ writeXml($value['childs'], $xml); } $xml->endElement(); } }}调用 writeXml($config);

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
