PHP Phar extension advancement: creating lightweight executable files

PHP The Phar extension is a powerful feature of PHP that can be used to package multiple files into a single executable file. In this article, PHP editor Baicao will introduce how to use Phar extension to create lightweight executable files. By studying the content of this article, readers will learn the basic usage and advanced techniques of Phar extensions, and how to effectively use Phar extensions to simplify the application deployment and distribution process. Let's explore the magic of Phar extensions together!

$phar = new Phar("my_app.phar");

You can then add files and directories using the addFile() method:

$phar->addFile("main.PHP");
$phar->aDDDirectory("includes");

Finally, build the Phar archive using the buildFromIterator() method:

$phar->buildFromIterator(new RecursiveDirectoryIterator("src"));

Set metadata You can set the metadata of a Phar archive using the setStub() and setSignatureAlGorithm() methods:

// 设置 Phar 入口文件
$phar->setStub("<?php Phar::mapPhar(); include "main.php"; ?>");

// 设置签名算法
$phar->setSignatureAlgorithm(Phar::SHA1);

Signature Phar Archive To make Phar archives more secure, you can sign the archive using the sign() method:

$phar->sign("my_key.pem", "my_cert.pem");

Distribution and Deployment Once you create a Phar archive, you can distribute and deploy it by copying the files to the target server or using a package manager such as Composer.

Execute Phar Archive To perform a Phar archive on linux and MacOS systems, use the following command:

php my_app.phar

On a windows system, use the following command:

php.exe my_app.phar

advantage Advantages of using Phar extensions include:

• Lightweight and portable, no additional dependencies required
• Easy to distribute and deploy, just copy a file
• Enhanced security, archive integrity can be verified through signatures
• Support compression to reduce archive size

limit The Phar extension also has some limitations:

• Not supported in some shared hosting environments
• The performance overhead is slightly higher than directly executing PHP scripts
• For large applications, management can become complex

Best Practices Best practices when creating and using Phar archives include:

• Use Phar archives as standalone applications rather than integrating them into existing applications
• Keep the Phar archive relatively small and include only necessary dependencies
• Use accurate metadata to describe the content and purpose of the Phar archive
• Consider using signatures to enhance security
• RegularlyTesting Phar archives to ensure they are working properly
