phpCMS 常用代码(一)
1.去掉标题限制后出现的省略号
{str_cut($r[title],36,'')}

2.格式化时间 2011-05-06 11:22:33
{date('Y-m-d H:i:s',$r[inputtime])}

3.格式化时间 2011年05月06日
{date('Y年m月d日',$r[inputtime])}

4.显示栏目名称(只是名称,不带链接)
{$catname}

5.显示栏目名称和链接(可以点击)
{$CATEGORYS[$r['catid']]['catname']}

6.外部数据源调用
{pc:get sql="SELECT * FROM pre_forum_thread" cache="3600" dbsource="discuz" return="data" num="10"}

7.调用子栏目(在栏目首页模板需要用到)
{pc:content action="category" catid="$catid" num="25" siteid="$siteid" order="listorder ASC"}{loop $data $r}
{$r[catname]} | {/loop}{/pc}

8.显示指定id的栏目名称 (例子这里catid=22)
{$CATEGORYS[22]['catname']}

9.在文章面前显示文章类别
{pc:content action="lists" catid="79" order="listorder DESC" num="14" }

{loop $data $n $r}

  • {if $TYPE[$r[typeid]][name]}[ {$TYPE[$r[typeid]][name]}] {/if}{str_cut($r[title],33,'')}

  • {/loop}{/pc}

    10.指定变量循环增长(幻灯片经常用到)
    {pc:content action="lists" catid="66" order="listorder DESC" thumb="1" num="5" }
    {php $num = 0}
    {loop $data $r}
    linkarr[{$num}] = "{$r[url]}";
    picarr[{$num}] = "{$r[thumb]}";
    textarr[{$num}] = "{str_cut($r[title],36,'')}";
    {php $num++}
    {/loop}
    {/pc}

    11.文章调用使用limit
    {pc:content action="position" posid="36" num="1" order="listorder DESC limit 1,1--" }
    其他都是跟以前一样使用
    {pc:content action="position" posid="31" order="listorder DESC" limit='1,8--'}
    {loop $data $r}
  • {str_cut($r[title],36,'')}

  • {/loop}

    {/pc}


    12.phpCMS链接查询  
               {pc:get sql="SELECT * FROM v9_news a join v9_news_data b on a.id=b.id where catid=27" cache="3600" page="$page" return="data"}
       

              
      {loop $data $key $val}         
    • {$val[title]}
    •         
      {/loop}    
        
    {if $pages}
    {$pages}
    {/if}
       {/pc}
                {$val[content]}


    13.phpCMS上一篇、下一篇
          上一篇:{$previous_page[title]}

          下一篇:{$next_page[title]}

      注意:a标签里面不能有target=“_blank”会发生错误。

    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.

    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.
