This tutorial focuses on how to automate file compression and extraction (zipping and unzipping) using PHP extensions.

The principal characteristics and functionalities described are centered around the PHP ZipArchive class:

1. Benefits of File Compression

Compressing files when transferring them over the internet offers several advantages:

• Reduced Size: The total size of files is significantly lowered.

• Bandwidth Saving: Compression helps save bandwidth.

• Faster Downloads: Users benefit from faster download speeds.

• Automation: Using PHP functions eliminates the tiresome process of manual compression.

2. Core Archive Management (Opening and Flags)

To start, a new ZipArchive instance is created, followed by calling the open($filename, [$flags]) method. Key optional flags determine how the archive is handled:

• ZipArchive::CREATE: Creates a new archive if one does not exist.

• ZipArchive::OVERWRITE: Overwrites existing contents in the specified archive.

• ZipArchive::EXCL: Results in an error if the archive already exists.

• ZipArchive::RDONLY: Allows opening the archive in read-only mode (available since PHP 7.4.3).

• Using combinations (e.g., ZipArchive::OVERWRITE|ZipArchive::CREATE) allows overwriting an existing archive while simultaneously creating a new one if none is found.

3. Adding Files (Compression)

Once the archive is opened, files can be added:

• Individual Files: The addFile($filename, $localname, $start, $length) method adds a file from a given path to the archive. The $localname parameter sets the file's name inside the archive.

• Multiple Files/Directory Matching: The addGlob($pattern, $flags, $options) method is used to archive multiple files (e.g., all .pdf or .png files).

  • The $options parameter (an associative array) controls the directory structure inside the archive.

  • Options include add_path (prefixing the file's local path) and removeallpath (removing everything from the path except the file name, adding it to the archive root).

• After adding files, the close() method is called to save changes and close the archive.

4. Extracting Content

The extractTo($destination, $entries) method is used to extract archive contents:

• It can extract everything inside the archive (if the second parameter is omitted) or specific files.

• When extracting specific files, the proper path of the file inside the archive must be specified.

• The directory and file structure are preserved during the extraction process.

5. Archive Modification and Control

The ZipArchive class provides further control over the archived contents:

• Counting Files: The number of files can be counted using the count() method or the numFiles property.

• Renaming: The renameName($oldname, $newname) function changes a file's name within the archive.

• Deleting: The deleteName() method can delete an individual file or an entire directory from the archive.

4. Extensions (Widgets and Plugins)

The framework includes two types of extensions:

• Widgets (Used in a Slide): These are Vue components that can be used directly within a slide. Examples include:

  • eg-modal.

  • eg-code-block (for code highlighting, requiring the user to install and configure highlight.js).

  • eg-toggle, eg-radio-button, eg-triggered-message.

• Plugins (Used Globally in a Slideshow): These enhance slide behavior across the presentation. Examples include:

  • Presenter Plugin: Enables a presenter mode (toggled by a configurable key, default 'p') that opens two windows (parent and child) which share control and can be used for private notes.

  • Zoom Plugin: Enables the zoom functionality.

5. Customization and Development

• Theming: Users can apply pre-built themes, such as argume and gourmet, by importing the necessary CSS and wrapping the presentation template with the corresponding theme class (e.g., eg-theme-gourmet).

• API Access: Developers can customize the framework by accessing and modifying slideshow methods like nextStep, previousStep, nextSlide, and previousSlide.

• Permalinks: Although not included by default, permalinks (using hashbangs or history mode) can be easily implemented using Vue-Router to maintain slide and step state in the URL.

PeerTube is an open-source, decentralized video-sharing platform developed by Framasoft, a French non-profit organization. It is promoted as a free and decentralized alternative to Big Tech's video platforms.

Here are the principal functionalities and features of PeerTube:

Core Philosophy and Architecture

• Decentralization and Federation: PeerTube is not a single centralized platform. It allows users to create their own independent video platforms. These individual platforms connect to each other to form a big network (federation) that is both autonomous and interconnected. This decentralizes video storage and decision-making power.

• Privacy and Ethics: The platform is free, open-source, and non-commercial. It does not depend on any advertising and does not track you. It considers users as people, not products to be profiled.

• Open Source and Transparency: PeerTube is provided freely, allowing users to look under the hood of its source code (it is auditable and transparent). It can be enhanced by contributions from anyone.

• Community Support: PeerTube exists thanks to donations, with over 90% of its funding coming from public interest contributions.

• Interoperability: It is based on ActivityPub to connect with other federated tools like Mastodon.

Broadcasting and Performance

• Peer-to-Peer (P2P) Broadcasting: PeerTube uses WebRTC, a free and open-source project, to enable peer-to-peer broadcasting.

• Bandwidth Reduction: P2P reduces server bandwidth overload, especially if a video becomes viral.

Features for Viewers

• Mobile Access: A mobile app is available to discover, watch, and share videos across the entire federated network using a single interface.

• Smooth Experience: The powerful video player offers quality settings, subtitles, and full-screen mode. The experience is comfortable and respectful, working without tracking or ads.

HTTP/3 is the third major version of the Hypertext Transfer Protocol (HTTP). This protocol is the foundation of data communication on the web.

Here are the key features of HTTP/3:

1. Core Protocol and Architecture

• QUIC Protocol: HTTP/3 is built on QUIC, a modern transport protocol that runs over UDP (User Datagram Protocol). This replaces the use of TCP (Transmission Control Protocol) found in its predecessors (HTTP/1.1 and HTTP/2).

• Enhanced Reliability: It replaces TCP’s three-way handshake with faster connection setups. QUIC uses 0-RTT and 1-RTT handshakes, which reduces delay and contributes to faster connection setup.

• RFC Standard: HTTP/3 is defined in RFC 9114.

2. Performance and Efficiency

• Elimination of HOL Blocking: HTTP/3 eliminates Head-of-Line (HOL) blocking at the transport layer. Unlike HTTP/2, if a packet is lost, it only affects individual streams, meaning delays in one part do not block the rest of the website.

• Faster Start Time: It provides a significantly faster start time, making website connections begin up to 80–90% faster than HTTP/2.

• Better Performance on Weak Networks: It offers better performance on mobile and high-latency networks. It handles bad or unstable internet connections more smoothly and can recover from lost data effectively.

• Connection Migration: HTTP/3 supports connection migration, which is particularly useful for users on mobile networks.

3. Security and Compatibility

• Built-in Encryption: It includes built-in encryption. TLS (Transport Layer Security) is mandatory and is integrated directly into QUIC, specifically using TLS 1.3.

• Modern Network Compatibility: HTTP/3 works well with modern networks because it uses UDP on port 443, which is already commonly used on the internet.

• Browser Support: It is already supported by major browsers including Chrome, Firefox, and Safari.

HTTP/3 acts like a modern multi-lane highway constructed specifically for data, where individual accidents (lost packets) affect only one lane, allowing the rest of the traffic (data streams) to continue moving rapidly, unlike previous protocols where a single accident could halt the entire road (HOL blocking).
