I encountered a tricky problem when developing a PHP project that requires high concurrency processing: how to implement asynchronous programming in PHP to improve program responsiveness and efficiency. Traditional synchronous programming methods seem unscrupulous when handling a large number of requests, resulting in slow response of programs and even timeout errors. I tried multiple methods, but none of them worked until I discovered the powerful tool library of React/Async.
React/Async is an asynchronous tool library designed for ReactPHP. It provides rich asynchronous control flow management functions to help developers better handle asynchronous operations. Its core idea is to implement asynchronous programming through Promise, avoiding traditional nested callbacks and chain calls, making the code clearer and easier to read.
Installing React/Async with Composer is very simple, just run the following command:
<code>composer require react/async:^4.3</code>
Here are some examples of using key functions:
-
async() and await() functions : These two functions are the core of React/Async, which allow you to write synchronous code in an asynchronous environment. For example:
<code class="php">Loop::addTimer(0.5, React\Async\async(function () { echo 'a'; React\Async\await(React\Promise\Timer\sleep(1.0)); echo 'c'; })); Loop::addTimer(1.0, function () { echo 'b'; }); // 輸出順序為"a"(0.5秒), "b"(1.0秒), "c"(1.5秒)</code>
With
async()
andawait()
, you can easily manage the execution order of asynchronous operations, avoiding the problem of callback hell. -
coroutine() function : This function allows you to use generators to implement asynchronous operations, making the code structure clearer. For example:
<code class="php">React\Async\coroutine(function () { $browser = new React\Http\Browser(); try { $response = yield $browser->get('https://example.com/'); echo $response->getBody(); } catch (Exception $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; } });</code>
With
coroutine()
you can handle asynchronous operations like writing synchronous code, greatly improving the readability and maintenance of the code. -
Parallel and Serial Execution : React/Async provides
parallel()
andseries()
functions, allowing you to execute a set of asynchronous tasks in parallel or serial. For example:<code class="php">React\Async\parallel([ function () { return new Promise(function ($resolve) { ... }); }, function () { return new Promise(function ($resolve) { ... }); }, ])->then(function (array $results) { ... });</code>
These functions allow you to choose parallel or serial execution tasks when needed, and flexibly manage the execution process of your program.
With React/Async, my PHP project became more efficient when handling high concurrent requests, with significantly reduced response time and significantly improved user experience. The advantage of React/Async is that it simplifies the complexity of asynchronous programming and provides powerful control flow management functions, allowing developers to focus more on the implementation of business logic.
In short, React/Async is a very practical tool library that not only solves the asynchronous programming difficulties I encountered in my PHP project, but also greatly improves the performance and maintainability of the program. If you are also troubled by asynchronous programming problems in PHP projects, try React/Async, which will bring unexpected results to you.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

The duration of the airdrop dividend is uncertain, but the LayerZero, StarkNet and ZK ecosystems still have long-term value. 1. LayerZero achieves cross-chain interoperability through lightweight protocols; 2. StarkNet provides efficient and low-cost Ethereum L2 expansion solutions based on ZK-STARKs technology; 3. ZK ecosystem (such as zkSync, Scroll, etc.) expands the application of zero-knowledge proof in scaling and privacy protection; 4. Participation methods include the use of bridging tools, interactive DApps, participating test networks, pledged assets, etc., aiming to experience the next generation of blockchain infrastructure in advance and strive for potential airdrop opportunities.

The coordinated rise of Bitcoin, Chainlink and RWA marks the shift toward institutional narrative dominance in the crypto market. Bitcoin, as a macro hedging asset allocated by institutions, provides a stable foundation for the market; Chainlink has become a key bridge connecting the reality and the digital world through oracle and cross-chain technology; RWA provides a compliance path for traditional capital entry. The three jointly built a complete logical closed loop of institutional entry: 1) allocate BTC to stabilize the balance sheet; 2) expand on-chain asset management through RWA; 3) rely on Chainlink to build underlying infrastructure, indicating that the market has entered a new stage driven by real demand.

Crypto market value exceeded US$3 trillion, and funds mainly bet on seven major sectors. 1. Artificial Intelligence (AI) Blockchain: Popular currencies include FET, RNDR, AGIX, Binance and OKX launch related trading pairs and activities, funds bet on AI and decentralized computing power and data integration; 2. Layer2 and modular blockchain: ARB, OP, ZK series, TIA are attracting attention, HTX launches modular assets and provides commission rebates, funds are optimistic about their support for DeFi and GameFi; 3. RWA (real world assets): ONDO, POLYX, XDC and other related assets, OKX adds an RWA zone, and funds are expected to migrate on traditional financial chains; 4. Public chain and platform coins: SOL, BNB, HT, OKB are strong

Yes, Web3 infrastructure is exploding expectations as demand for AI heats up. Filecoin integrates computing power through the "Compute over Data" plan to support AI data processing and training; Render Network provides distributed GPU computing power to serve AIGC graph rendering; Arweave supports AI model weights and data traceability with permanent storage characteristics; the three are combining technology upgrades and ecological capital promotion, and are moving from the edge to the underlying core of AI.

The most popular tracks for new funds currently include re-staking ecosystems, integration of AI and Crypto, revival of the Bitcoin ecosystem and DePIN. 1) The re-staking protocol represented by EigenLayer improves capital efficiency and absorbs a large amount of long-term capital; 2) The combination of AI and blockchain has spawned decentralized computing power and data projects such as Render, Akash, Fetch.ai, etc.; 3) The Bitcoin ecosystem expands application scenarios through Ordinals, BRC-20 and Runes protocols to activate silent funds; 4) DePIN builds a realistic infrastructure through token incentives to attract the attention of industrial capital.

Yes, the altcoin rebound may indicate that a new bull market has begun, but entry should be cautious. 1. Market sentiment has recovered, and the trading volume of altcoins on platforms such as Binance, Ouyi, and Huobi has surged, and funds have flowed into the AI, Layer2, and GameFi sectors; 2. The counterfeit rebound shows the characteristics of the early bull market, Bitcoin has stabilized, hot spot rotation has accelerated, and new projects have frequently been launched; 3. Whether to enter the market needs to be judged based on investment strategy: long-term investors can gradually build positions in leading projects, short-term traders can pay attention to opportunities in active currency bands, and try new coins in small positions to avoid chasing highs; 4. In the future, we need to observe whether Bitcoin can break through the previous high, the flow of funds on the three major platforms, the Fed's policies and on-chain activity and other key indicators to judge the sustainability of the market.

In the ever-changing virtual currency market, timely and accurate market data is crucial. The free market website provides investors with a convenient way to understand key information such as price fluctuations, trading volume, and market value changes of various digital assets in real time. These platforms usually aggregate data from multiple exchanges, and users can get a comprehensive market overview without switching between exchanges, which greatly reduces the threshold for ordinary investors to obtain information.
