This article mainly introduces how to use php code in smarty template language. It has certain reference value. Now I share it with you. Friends in need can refer to it.
With the help of two smarty internal Build function.
1. The inluce_php function is used to include php scripts in the template. If the safe mode is set, the included script must be located in the $trusted_dir path. The include_php function must set the file attribute, which specifies the included php file. The path can be a relative path to $trusted_dir or an absolute path.
For example:
{include_php file="test.php"}
Example:
load_nav.php ------------- <?php // load in variables from a mysql db and assign them to the template // 从mysql数据库中取得数据,将数据赋给模板变量 require_once("MySQL.class.php"); $sql = new MySQL; $sql->query("select * from site_nav_sections order by name",SQL_ALL); $this->assign('sections',$sql->record); ?> index.tpl --------- {* absolute path, or relative to $trusted_dir *} {* 绝对路径或 $trusted_dir 的相对路径 *} {include_php file="/path/to/load_nav.php"} {foreach item="curr_section" from=$sections} <a href="{$curr_section.url}">{$curr_section.name}</a><br> {/foreach}
2. The php tag allows php to be directly embedded in the template Script, whether to process these statements depends on the setting of $php_handling. This statement usually does not need to be used, of course, if you know this feature very well or think it is necessary to use it, you can also use it.
For example:
{php}
echo "This is the function of php's built-in function";
{/php}
Example:
{php} // including a php script directly // from the template. include("/path/to/display_weather.php"); {/php}

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
