When using templates, you will encounter such a problem: it is troublesome to display paging information, and multiple templates have paging blocks.
For example:
---20 records in total, current 3/5 pages Home Page Previous Page Next Page Last Page GO-----
Friends who have encountered this problem for the first time are considering When solving this problem, it seems that everyone is thinking about how to use PHP to implement it, but no matter how you design it, there are two options: 1. Use nested loops to implement it
2. It uses n multiple judgments to do
but it is still troublesome in the end, and server-side resources are used during parsing.
Why not use javascript instead of php! ! ! ! , this can reduce the amount of code in the php script, and can also leave the work of parsing paging to the client itself. However, debugging JavaScript may be more troublesome.
The most important thing is that it can simplify the pain of parsing templates when displaying pagination.
The following is a template parsed by an itx template tool that supports pear.
Where and represent a block, {recordcount} Such similar strings are variables.
----------------list.tpl--------------------------

Copy code The code is as follows:
//Other html code



> ;




//Other html code
--------------------page.js------ ------
//--------------- 20 records in total, current 3/5 pages Home Page Previous Page Next Page Last Page GO---- ---------------
//recordCount = 20;
//show = 20
//pageCount = 5;
//pageNow = 3;
//pageStr = "?page=_page_";
//document.write(showListPage(recordCount, show, pageCount, pageNow, pageStr));
function showListPage0(recordCount, show, pageCount, pageNow , pageStr){
if(pageCountif(pageNowstr = '
total records, current'+pageNow+'/'+pageCount+' page';
if(pageNowstr + = "Home";
else
str += " Homepage ";
if(pageNowstr += " Previous page";
else
str += " Previous page ";
if(pageNow>=pageCount)
str += " Next page";
else
str += " Next page ";
if(pageNow>=pageCount)
str += " Last page";
else
str += " Last page ";
str += "Jump topage";
str += "
";
return str;
}
function pagego0(pageGo,pageNow,pageCount,pageStr){
if(pageGo>=1 && pageGowindow.location = pageStr.replace("_page_", pageGo);
}

Also This method can be used even without templates, and it is still a good paging solution. Just replace strings like {recordcount} with the value of a variable.

How can you check if a PHP session has already started?How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
