This article describes the usage of reserved variables in PHP template engine Smarty. Share it with everyone for your reference, the details are as follows:
In Smarty, there are some reserved variables that can be used directly without the need for PHP scripts to assign them, that is, there is no need to use $_tpl->assign('var','value') to assign them.
1. Access the variables of the page request in the template
{$smarty.get.user} == $_GET['user'] {$smarty.post.user} == $_POST['user'] {$smarty.cookie.username} == $_COOKIE['username'] {$smarty.session.username} == $_SESSION['username'] {$smarty.server.REMOTE_ADDR} == $_SERVER["REMOTE_ADDR"] {$smarty.env.PATH} == $_ENV['PATH'] {$smarty.request.username} == $_REQUEST['username']
2. Access constants and system constants defined in PHP scripts in template files
{$smarty.const.__FILE__} //當(dāng)前執(zhí)行的 PHP 文件 {$smarty.const.CONST_VAR} //訪問 PHP 腳本中 define 定義的常量
3. Get the current server time in the template file
Copy code The code is as follows: {$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"} == PHP date('Y-m-d H:i:s',time())
in script4. Access of configuration files in templates
Template variables in the configuration file can be accessed through {$smarty.config.Configuration Variables}. In this case, there are two ways to access the variables in the configuration file in the template: 1. {#Configuration Variables#}; 2. {$smarty.config.Configuration Variables}, if there is a zone, the same is true.
5. Get the data captured by Smarty’s built-in function capture
The function of the capture function is to capture the data output by the template and store it in a variable instead of outputting them to the page. Any data between {capture name="foo"} and {/capture} will is stored in the variable $foo, which is specified by the name attribute. Access this variable through $smarty.capture.foo in the template. If the name attribute is not specified, the function will use "default" as the parameter by default.
6. Reserved variables $smarty.foreach
$smarty.foreach obtains some information about the foreach loop array, such as the number of arrays, incrementing by 1..., for details on the use of $smarty.foreach, please refer to the previous article "PHP template engine Smarty built-in function foreach" , foreachelse usage analysis》

The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.

1. Maximizing the commercial value of the comment system requires combining native advertising precise delivery, user paid value-added services (such as uploading pictures, top-up comments), influence incentive mechanism based on comment quality, and compliance anonymous data insight monetization; 2. The audit strategy should adopt a combination of pre-audit dynamic keyword filtering and user reporting mechanisms, supplemented by comment quality rating to achieve content hierarchical exposure; 3. Anti-brushing requires the construction of multi-layer defense: reCAPTCHAv3 sensorless verification, Honeypot honeypot field recognition robot, IP and timestamp frequency limit prevents watering, and content pattern recognition marks suspicious comments, and continuously iterate to deal with attacks.

PHP ensures inventory deduction atomicity through database transactions and FORUPDATE row locks to prevent high concurrent overselling; 2. Multi-platform inventory consistency depends on centralized management and event-driven synchronization, combining API/Webhook notifications and message queues to ensure reliable data transmission; 3. The alarm mechanism should set low inventory, zero/negative inventory, unsalable sales, replenishment cycles and abnormal fluctuations strategies in different scenarios, and select DingTalk, SMS or Email Responsible Persons according to the urgency, and the alarm information must be complete and clear to achieve business adaptation and rapid response.

PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.

Select the appropriate AI voice recognition service and integrate PHPSDK; 2. Use PHP to call ffmpeg to convert recordings into API-required formats (such as wav); 3. Upload files to cloud storage and call API asynchronous recognition; 4. Analyze JSON results and organize text using NLP technology; 5. Generate Word or Markdown documents to complete the automation of meeting records. The entire process needs to ensure data encryption, access control and compliance to ensure privacy and security.
