HomeBackend DevelopmentPHP TutorialSummary of destoon secondary development templates and calling syntax_PHP tutorial

1. Template storage and calling rules

The template is stored in the system template directory, a directory under the template directory
For example: template/default/ is a set of templates

Template files have a .htm extension and can be stored directly in the template directory
For example template/default/index.htm
It can also be stored in a subdirectory of the template directory
For example: template/default/member/index.htm

In PHP files, use template syntax as

<&#63;php
 include template('index');
&#63;>

or

<&#63;php
 include template('index', 'member');
&#63;>

If the current default template system is default, then:

<&#63;php
 include template('header');
&#63;>

means using template/default/header.htm template file

<&#63;php
 include template('header', 'member');
&#63;>

means using template/default/member/header.htm template file

These.name.php in the template directory is the configuration file of the template alias. The template alias can be modified in the background template management.

The cache file after template parsing is saved in the cache/tpl/ directory, with the extension .tpl.php

2. Template syntax

1. Contain template : {template 'header'} or {template 'header', 'member'}

{template 'header'} is parsed as

<&#63;php
 include template('header');
&#63;>

means using template/default/header.htm template file

{template 'header', 'member'}

is parsed as:

<&#63;php
 include template('header','member');
&#63;>

means using template/default/member/header.htm template file

2. Variable or constant representation:

Variable {$destoon} is parsed as:

<&#63;php
 echo $destoon;
&#63;>

The constant {DESTOON} is parsed as:

<&#63;php
 echo DESTOON;
&#63;>

For arrays, the standard writing method should be, for example, {$destoon['index']}, which can be abbreviated as {$destoon[index]}. The template will automatically add quotation marks when parsing.

3. Function {func_name($par1, $par2)}

{func_name($par1, $par2)} is parsed as

<&#63;php
 func_name($par1, $par2);
&#63;>

4. PHP expression {php expression}

{php expression} is parsed as

<&#63;php
 expression 
&#63;>

5. Conditional statement {if $a=='b'} do A {/if} or {if $a=='b'} do A {else} do B {/if } or {if $a=='b'} do A{elseif $b=='c'} do C {else} do B {/if}

{if $a=='b'} do A {/if} is parsed as

<&#63;php
 if($a=='b') {
 do A
 }
&#63;>

{if $a=='b'} do A {else} do B {/if} is parsed as

<&#63;php
 if($a=='b') {
 do A 
 } else {
 do B
 } 
&#63;>

{if $a=='b'} do A {elseif $b=='c'} do C {else} do B {/if} is parsed as

<&#63;php
 if($a=='b') {
 do A 
 } else if($b=='c') {
 do C
 } else {
 do B
 } 
&#63;>

6. LOOP loop {loop $var $v}...{loop} or

{loop $var $k $v}...{loop}

{loop $var $v}...{loop} is parsed as

<&#63;php
 if(is_array($var)) {
 foreach($var as $v) {
 ... }
 }
&#63;>

{loop $var $k $v}...{loop} is parsed as

<&#63;php
 if(is_array($var)) {
 foreach($var as $k=>$v) {
 ... }
 }
&#63;>

3. Special usage

1. Variables or expressions can be annotated with HTML , for example is still parsed as ( Such comments can be automatically filtered)

2. You can write PHP code directly in the template . Directly writing PHP code is compatible with the DESTOON template syntax.

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
