Smarty function---Plug-in
1) Built-in functions sysplugins are not allowed to be modified
2) Custom functions plugins can be modified
1. capture captures a piece of content but does not output it
Grammar:
{capture name=‘var’}
Contents
{/capture}
Name: Save the content to the specified variable
{$smarty.capture.var}
In templates, if a large amount of content needs to be output repeatedly, you can consider using capture to capture.
2. config_load Load the configuration file
{config_load file=”file” section=”section”}
file: Configuration file name
section: which configuration section to reference. Optional parameter
Quote syntax:
{#var#}
{$smarty.config.var}
3. foreach, foreachelse are used to traverse arrays
Grammar:
{foreach from=array key=key name=name item=content}
{foreachelse} When the array to be traversed does not have any elements, execute the statement following foreachelse
{/foreach}
From: Array to be traversed
Item: The key value traversed
Key: The key name traversed
Name: Name the foreach statement
Foreach built-in variables
$smarty.foreach.name.index: Index starts from 0
$smarty.foreach.name.iteration : Index starts from 1
$smarty.foreach.name.first: This value is true when the loop is executed for the first time
$smarty.foreach.name.last: This value is true when the loop is executed for the last time
$smarty.foreach.name.total: total number of loops
4. include refers to another template file
{include file="file" assign="var" [var ...]}
File: Template file to be imported
Assign: Save the result, but do not output it this time
[var…]: Optional parameters, passed to the template file
5. include_php Contains a php file
{ include_php file="file" assign="var" once="true|false"}
File: php file to be imported
Assign: Save the output result, but do not output it this time
Once: Whether it only contains once true: yes false: no
This function is available in smarty2.6, but it was removed in 3.0. If you still want to use this function, you can reference the SmartyBC.class.php class file
6. insert In the template, execute a php function
Grammar:
{ insert name="func" [var ...] }
Name: The name of the php function being called
[var...]: Specify parameters when calling the function. Optional parameters
Insert and include_php are the same. They are all functions in 2.6. In 3.0, this function is placed in the file SmartyBC.class.php.
Note: The name of the php function referenced by insert must be prefixed with insert_
7.if elseif else
{if}
{elseif}
{else}
{/if}
8. The escape character of { } in ldelim and rdelim templates
{ldelim}
{rdelim}
9. literal The content in the literal tag will not be parsed by smarty
{literal}
…
{/literal}
10.php You can write php code in a pair of php tags
{php}

The above introduces php-Smarty-4 (21), including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
