As the scale and complexity of data increase, traditional batch processing and data warehouse technologies can no longer meet the needs of modern enterprises. Real-time data processing and analysis has become a goal pursued by data scientists and engineers. Apache Flink is a stream processing and computing engine that can be used for real-time data stream processing, with high throughput, low latency and fault tolerance. This article will discuss how to use Flink for stream processing and calculation in PHP development.

Apache Flink is a stream processing and computing engine that supports multiple languages ​​and APIs. It is designed to handle data streams and can process billions of data at the second level. Flink adopts a distributed stream processing model, which can process static and dynamic data at the same time, and can perform complex data processing and analysis tasks on real-time streams. In addition, Flink also supports multiple computing modes such as batch processing, machine learning, graphics processing, and complex event processing.

Although PHP is a commonly used web development language, it has weak capabilities in large-scale data processing and analysis. Therefore, a stream processing and computing engine is needed to enhance its ability to handle large-scale data. You can use Apache Flink's PHP library and use Flink's stream processing and computing capabilities in PHP, thereby enhancing PHP's ability to process large-scale data.

First you need to install Flink, which can be downloaded from Flink’s official website. Once downloaded, they can be extracted to any directory. For example, we can extract them into the /home/user/apache-flink directory.

Step 2: Install PHP application

You need to create a PHP application and install related dependencies. For example, use Composer to install PHP dependencies. You can use Composer to create a file called composer.json that contains all the required dependencies. For example:

{
    "require": {
        "flink/php-client": "^3.0"
    }
}

Additionally, the php-client dependency needs to be added to the composer.json file. For example:

"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/apache/flink.git"
    }
]

To use Apache Flink for stream processing and calculations, you need to set up a client connected to Flink. In PHP, you can create a client object using the flinkclientClient class. For example:

$client = new linkclientClient('localhost', 8081);

After the client connects to Flink, you can use the flinkJobSubmissionService API and flinkJobClient class to submit jobs and process results. For example:

$jarFilePath = '/home/user/WordCount.jar';
$jobArgs = 'input-file output-file';
$jobClient = $client->getJobSubmissionService();
$job = $jobClient->submitJar($jarFilePath, $jobArgs);
$jobStatus = $jobClient->getStatus($job->getJobID());
while (!$jobStatus->isTerminalState()) {
    sleep(1);
    $jobStatus = $jobClient->getStatus($job->getJobID());
}
$results = $jobClient->getJobResult($job->getJobID());

This code will submit a job called WordCount that reads some text from an input file and writes the results to an output file. You can obtain the job execution result by calling the getJobResult() function on the $jobClient object.

Summary

Apache Flink is a powerful stream processing and computing engine that can be used for real-time data stream processing with high throughput, low latency and fault tolerance. Using Apache Flink in PHP development can enhance PHP's ability to process large-scale data. This article provides some basic steps to use Flink’s stream processing and computing capabilities. I hope readers can learn from this article how to use Apache Flink for stream processing and computing.

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php怎么除以100保留两位小数php怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PM

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

php怎么根据年月日判断是一年的第几天php怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php怎么判断有没有小数点php怎么判断有没有小数点Apr 20, 2022 pm 08:12 PM

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

php字符串有没有下标php字符串有没有下标Apr 24, 2022 am 11:49 AM

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。
