This article mainly introduces the dynamic loading and paging of php and xml. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

This is watching the Pacific Network I saw in the comments that Pacific.com uses jsp as the backend language to generate xml files. Then bind the data to html. I also made one using php. The following is the source file.

-----------------xml.htm------------------

  function jump(form)
  {
 if (form.pageNum.value>parseInt(pageCount.innerHTML)) return false;
 if (form.pageSize.value>parseInt(recordCount.innerHTML)) return false;
    ShopList.src="xml.php?pageNo="+form.pageNum.value+"&pageSize="+form.pageSize.value+"&time="+(new Date()).getTime();
  }
  function pageCount_onpropertychange(form)
  {
   if (form.pageNum.value>parseInt(pageCount.innerHTML)) form.pageNum.value=parseInt(pageCount.innerHTML);
 if (form.pageSize.value>parseInt(recordCount.innerHTML)) form.pageSize.value=parseInt(recordCount.innerHTML);
    if(form.pageNum.value==1)
    {
      form.firstPage.disabled=true;
      form.previousPage.disabled=true;
    }
    else

The above php, the comments are the data I obtained by connecting to the database. Since I put it up for testing, there is no database connection, so I changed it. I have just started to understand xml, and I still don’t understand many things. Funny...

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency 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.
