There are several ways to find keys in Redis: use the SCAN command to iterate over all keys by pattern or condition. Use GUI tools such as Redis Explorer to visualize the database and filter keys by name or schema. Write external scripts to query keys using the Redis client library. Subscribe to keyspace notifications to receive alerts when key changes.

How to find keys in Redis

There are a variety of ways to find keys in Redis, depending on your specific needs and the tools available.

1. Manual command: SCAN

The SCAN command allows you to iterate over all keys in the Redis database by schema or specific conditions. The syntax is as follows:

 <code>SCAN cursor [PATTERN] [COUNT] [TYPE]</code>
  • cursor : A marker indicating where to start scanning.
  • PATTERN (optional): The key pattern to match.
  • COUNT (optional): The number of keys returned per iteration.
  • TYPE (optional): The type of key to return (for example, string, list).

2. Using the Redis Explorer GUI

If you use GUI tools such as Redis Explorer, you can easily visualize your database and find specific keys. These tools usually provide search functionality that allows you to filter keys by name or pattern.

3. External scripts

You can use external scripts (such as Python or Ruby) to write code to connect to Redis and query the key. This requires the use of Redis client libraries such as redis-py or hiredis.

4. Use keyspace notifications

Redis provides keyspace notifications that allow you to subscribe to notifications about key changes in the database. You can use this feature to receive alerts when the key is updated, deleted, or created.

Example: Use the SCAN command to find keys

 <code>redis> SCAN 0 MATCH mykey* 1) (integer) 0 2) 1) "mykey1" 2) "mykey2" 3) "mykey3"</code>

This command returns all keys that match the pattern "mykey*" and resets the cursor to 0.

How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization 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 calls AI intelligent voice assistant PHP voice interaction system construction 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.

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 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.

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.

Use Seaborn's jointplot to quickly visualize the relationship and distribution between two variables; 2. The basic scatter plot is implemented by sns.jointplot(data=tips,x="total_bill",y="tip",kind="scatter"), the center is a scatter plot, and the histogram is displayed on the upper and lower and right sides; 3. Add regression lines and density information to a kind="reg", and combine marginal_kws to set the edge plot style; 4. When the data volume is large, it is recommended to use "hex"

To build a PHP content payment platform, it is necessary to build a user management, content management, payment and permission control system. First, establish a user authentication system and use JWT to achieve lightweight authentication; second, design the backend management interface and database fields to manage paid content; third, integrate Alipay or WeChat payment and ensure process security; fourth, control user access rights through session or cookies. Choosing the Laravel framework can improve development efficiency, use watermarks and user management to prevent content theft, optimize performance requires coordinated improvement of code, database, cache and server configuration, and clear policies must be formulated and malicious behaviors must be prevented.

PHP development user permission management monetization PHP permission control and role management PHP development user permission management monetization PHP permission control and role management Jul 25, 2025 pm 06:51 PM

User permission management is the core mechanism for realizing product monetization in PHP development. It separates users, roles and permissions through a role-based access control (RBAC) model to achieve flexible permission allocation and management. The specific steps include: 1. Design three tables of users, roles, and permissions and two intermediate tables of user_roles and role_permissions; 2. Implement permission checking methods in the code such as $user->can('edit_post'); 3. Use cache to improve performance; 4. Use permission control to realize product function layering and differentiated services, thereby supporting membership system and pricing strategies; 5. Avoid the permission granularity is too coarse or too fine, and use "investment"
