注:'//+' 表示为本人另外加上的注释Class TypeLink
{
var $typeDir;
var $dsql;
var $TypeID; //+ 类别ID
var $baseDir; //+ 站点根网址
var $modDir; //+ 模板目录
var $indexUrl; //+ 主页链接地址
var $indexName; //+ 主页链接名
var $TypeInfos; //+ 类目信息
var $SplitSymbol; //+ 栏目位置的间隔符号
var $valuePosition; //+ 主页 > 国内 > 两会动态 > (带连接)
var $valuePositionName; //+ 主页 > 国内 > 两会动态 > (不带连接)
var $OptionArrayList; //+ 类目下拉列表
功能一,获得某类目的链接
复制代码 代码如下:
//获得某分类连接的URL
function GetOneTypeUrl($typeinfos)
{
return GetTypeUrl();
}
//获得某个类目的超链接信息
function GetOneTypeLink($typeinfos)
{
$typepage = $this->GetOneTypeUrl($typeinfos);
$typelink = "".$typeinfos['typename']."";
return $typelink;
}
功能二,获得某类目的链接列表 如:'类目一>类目二>' 这样的形式。
复制代码 代码如下:
//islink 表示返回的列表是否带连接
//+ SplitSymbol 栏目位置的间隔符号 dede系统默认为'-'
function GetPositionLink($islink=true)
{ //+ 获得 主页链接名
$indexpage = "".$this->indexName."";
……
……
else
{
if($islink)
{
$this->valuePosition = $this->GetOneTypeLink($this->TypeInfos);
if($this->TypeInfos['reid']!=0)
{
//调用递归逻辑
$this->LogicGetPosition($this->TypeInfos['reid'],true);
}
$this->valuePosition = $indexpage.$this->SplitSymbol.$this->valuePosition;
return $this->valuePosition.$this->SplitSymbol;
}
else
{
$this->valuePositionName = $this->TypeInfos['typename'];
if($this->TypeInfos['reid']!=0)
{
//调用递归逻辑
$this->LogicGetPosition($this->TypeInfos['reid'],false);
}
return $this->valuePositionName;
}
}
}
//获得某类目的链接列表,递归逻辑部分
function LogicGetPosition($id,$islink)
{
$this->dsql->SetQuery(" SQL查询语句 ");
$tinfos = $this->dsql->GetOne();
if($islink)
{ //+ 列表带连接
$this->valuePosition = $this->GetOneTypeLink($tinfos).$this->SplitSymbol.$this->valuePosition;
}
else
{ //+ 列表不带连接
$this->valuePositionName = $tinfos['typename'].$this->SplitSymbol.$this->valuePositionName;
}
if($tinfos['reid']>0)
{ //+ 递归
$this->LogicGetPosition($tinfos['reid'],$islink);
}
}
功能三, 获得类别列表 高级搜索功能 即highsearch.php 即要用到此函数
复制代码 代码如下:
//hid 是指默认选中类目,0 表示“请选择类目”或“不限类目”
//oper 是用户允许管理的类目,0 表示所有类目
//channeltype 是指类目的内容类型,0 表示不限频道
function GetOptionArray($hid=0,$oper=0,$channeltype=0,$usersg=0)
{
return $this->GetOptionList($hid,$oper,$channeltype,$usersg);
}
function GetOptionList($hid=0,$oper=0,$channeltype=0,$usersg=0)
{
return $this->OptionArrayList;
}
//+ 为下级类目递归加上 '-'
function LogicGetOptionArray($id, $step, $oper=0)
{
}
功能四,
//获得与该类相关的类目,本函数应用于模板标记{dede:channel}{/dede:channel}中
//$typetype 的值为: sun 下级分类 self 同级分类 top 顶级分类
复制代码 代码如下:
function GetChannelList($typeid=0,$reid=0,$row=8,$typetype='sun',$innertext='',
$col=1,$tablewidth=100,$myinnertext='')
{
}
}

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
