The way to process raw POST data in PHP is to use $rawData = file_get_contents('php://input'), which is suitable for receiving JSON, XML, or other custom format data. 1. php://input is a read-only stream that is only valid in POST requests; 2. Common problems include server configuration or middleware reading input streams, which makes it impossible to obtain data; 3. Application scenarios include receiving front-end fetch requests, third-party service callbacks, and building RESTful APIs; 4. The difference from $_POST is that $_POST automatically parses standard form data, while the original data is suitable for non-standard formats and allows manual parsing; 5. It is recommended to use $_POST for ordinary HTML forms, and it is recommended to use original data to separate projects from front-end or external system docking.
Processing raw POST data in PHP is often used to receive data in non-standard form formats, such as JSON, XML, or other custom formats. Unlike $_POST
, which automatically parses data, the original POST data needs to be manually retrieved and processed.

Methods to get raw POST data
PHP provides a convenient input stream to read raw POST data:

$rawData = file_get_contents('php://input');
This is the most commonly used method and is suitable for most scenarios. It should be noted that php://input
is a read-only stream, and data can only be read when the request method is POST, and an empty string will be returned in the GET request.
FAQ:

-
file_get_contents('php://input')
is used but the data cannot be read: it may be that the server configuration or middleware (such as some frameworks) has read the input stream once. - Some server environments (such as using certain FastCGI configurations) may limit the use of this stream.
Application scenarios of raw POST data
Raw POST data is often used in the following situations:
- Receives JSON data sent by the front-end via
fetch
orXMLHttpRequest
. - Process data transmitted from third-party service callbacks (such as payment gateways, webhooks, etc.).
- Build API interfaces, especially RESTful type service endpoints.
For example, the front-end sends the following request:
fetch('/api/endpoint', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ name: 'John', age: 30 }) });
The backend can read and parse it in the following way:
$data = json_decode(file_get_contents('php://input'), true);
In this way $data['name']
can get 'John'
.
Difference and choice between $_POST
$_POST
is a standard form data automatically parsed by PHP and is only applicable to application/x-www-form-urlencoded
and multipart/form-data
formats. The original POST data has no format restrictions and is suitable for more flexible scenarios.
When to use $_POST
?
- The traditional way of form submission.
- The data structure is simple and does not require nested or complex types.
When to use raw data?
- Transfer using JSON, XML and other formats.
- Third-party interface calls, the data format is fixed but not necessarily a standard form.
- Want to have complete control over the data parsing process.
If it is just a normal HTML form submission, it is more convenient to use $_POST
; if it is a front-end separation project or docking with external systems, it is recommended to use the original data method.
Basically that's it. By mastering the use of php://input
, and then choosing whether to parse it into JSON or other formats according to actual needs, you can deal with most of the processing scenarios of raw POST data.

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

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.

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 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 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.
