$routes->scope('/', function (RouteBuilder $builder) {
$builder->registerMiddleware('csrf', new CsrfProtectionMiddleware([
'httpOnly' => true,
]));
$builder->applyMiddleware('csrf');
//$builder->connect('/pages',['controller'=>'Pages','action'=>'display', 'home']);
$builder->connect('cookie/testcookies',['controller'=>'CakePHP Cookie Managements','action'=>'testCakePHP Cookie Managements']);
$builder->fallbacks();
});
Create a CakePHP Cookie ManagementsController.php file at src/Controller/CakePHP Cookie ManagementsController.php. Copy the following code in the controller file.
src/Controller/CakePHP Cookie Managements/CakePHP Cookie ManagementsController.php
<?php namespace App\Controller;
use App\Controller\AppController;
use Cake\Http\CakePHP Cookie Management\CakePHP Cookie Management;
use Cake\Http\CakePHP Cookie Management\CakePHP Cookie ManagementCollection;
class CakePHP Cookie ManagementsController extends AppController{
public $cookies;
public function testCakePHP Cookie Managements() {
$cookie = new CakePHP Cookie Management('name','XYZ');
$this->cookies = new CakePHP Cookie ManagementCollection([$cookie]);
$cookie_val = $this->cookies->get('name');
$this->set('cookie_val',$cookie_val->getValue());
$isPresent = $this->cookies->has('name');
$this->set('isPresent',$isPresent);
$this->set('count', $this->cookies->count());
$test = $this->cookies->remove('name');
$this->set('count_afterdelete', $test->count());
}
}
?>
Create a directory CakePHP Cookie Managements at src/Template and under that directory create a View file called test_cookies.php. Copy the following code in that file.
src/Template/CakePHP Cookie Management/test_cookies.php
The value of the cookie is: <?php echo $cookie_val; ?> <br> <?php if($isPresent): ?> The cookie is present. <?php else: ?> The cookie isn't present. <?php endif; ?> <br> <?php echo "The count of cookie before delete is :" .$count; ?> <br> <?php echo "The count of cookie after delete is :" .$count_afterdelete; ?>
Output
Execute the above example by visiting the following URL ? http://localhost/cakephp4/cookie/testcookies

How to use PHP to build social sharing functions PHP sharing interface integration practice
Jul 25, 2025 pm 08:51 PM
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.
How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization
Jul 25, 2025 pm 08:57 PM
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
PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy
Jul 25, 2025 pm 08:27 PM
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 calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
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.
How to use PHP to combine AI to generate image. PHP automatically generates art works
Jul 25, 2025 pm 07:21 PM
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.
PHP realizes commodity inventory management and monetization PHP inventory synchronization and alarm mechanism
Jul 25, 2025 pm 08:30 PM
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.
How to use PHP to develop AI-driven advertising delivery PHP advertising performance optimization solution
Jul 25, 2025 pm 06:12 PM
PHP provides an input basis for AI models by collecting user data (such as browsing history, geographical location) and pre-processing; 2. Use curl or gRPC to connect with AI models to obtain click-through rate and conversion rate prediction results; 3. Dynamically adjust advertising display frequency, target population and other strategies based on predictions; 4. Test different advertising variants through A/B and record data, and combine statistical analysis to optimize the effect; 5. Use PHP to monitor traffic sources and user behaviors and integrate with third-party APIs such as GoogleAds to achieve automated delivery and continuous feedback optimization, ultimately improving CTR and CVR and reducing CPC, and fully implementing the closed loop of AI-driven advertising system.
