上面是我要改的xml文件,要修改里的4个的值和smallinfo属性,求大神帮帮忙。


回复讨论(解决方案)

这个主要涉及到xml DOM的操作吧,去看看这方面的内容吧。

用 xml DOM 

if ( file_exists ( 'out.xml' )) {     $xml  = simplexml_load_file ( 'out.xml' );      foreach ($xml->pic->list as $key => $value) {      	$attr = (array) $value->attributes ();      	var_dump($attr['@attributes']['smallinfo']);      } } else {    exit( 'Failed to open test.xml.' );}
 这个只能取到里面的值 想改里面的值建议去下个simple_html_dom或者phpQuery

$s =<<< XML<?xml version='1.0' encoding='GB2312'?><img List alt="请问怎么在php里修改xml文件?" ><pic><list path="images/01.jpg"   smallpath="images/01.png" smallinfo="黑客的局域网攻击">.html/article/hardware/008.html</list><list path="images/02.jpg"   smallpath="images/02.png" smallinfo="维护你的光驱">http://www.niutuku.com/</list><list path="images/03.jpg" smallpath="images/03.png" smallinfo="数字地球">http://www.niutuku.com/</list><list path="images/04.jpg" smallpath="images/04.png" smallinfo="网络改变生活">http://www.niutuku.com/</list></pic><rollTime fade_in="10">3</rollTime><text font="微软雅黑" size="14" bold="true" color="0xfffffff"></text></imgList>XML;$xml = simplexml_load_string($s);for($i=0; $ipic->list); $i++) {  $xml->pic->list[$i] = $i;  $t = $xml->pic->list[$i]->attributes();  $t['smallpath'] = $i;}echo $xml->asXML();

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

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.

Best PHP Performance Optimization TechniquesBest PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
