FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package byte-buffer
Zeran ByteBuffer
A PHP library for binary data manipulation with support for multiple buffer implementations.
Introduction
Zeran ByteBuffer is a powerful library for manipulating binary data in PHP. It provides a consistent interface for working with byte arrays and binary strings, supporting operations like reading and writing integers, floats, doubles, and strings in both little-endian and big-endian formats.
The library includes two primary implementations:
ArrayBuffer: Stores data as an array of integersStringBuffer: Stores data as a string, which can be more memory-efficient
Installation
You can install the package via composer:

Type Range Limitations
The library automatically validates that values fit within their specified type ranges:
| Type | Size (bytes) | Range |
|---|---|---|
| Int8 | 1 | -128 to 127 |
| UInt8 | 1 | 0 to 255 |
| Int16 | 2 | -32,768 to 32,767 |
| UInt16 | 2 | 0 to 65,535 |
| Int24 | 3 | -8,388,608 to 8,388,607 |
| UInt24 | 3 | 0 to 16,777,215 |
| Int32 | 4 | -2,147,483,648 to 2,147,483,647 |
| UInt32 | 4 | 0 to 4,294,967,295 |
| Int64 | 8 | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |
| UInt64 | 8 | 0 to 18,446,744,073,709,551,615 |
Endianness
Most methods come in two variants:
- Standard (e.g.,
writeInt32): Uses little-endian (least significant byte first) - BE suffix (e.g.,
writeInt32BE): Uses big-endian (most significant byte first)
Which Implementation to Use?
ArrayBuffer: Better for cases where you need to manipulate individual bytes frequentlyStringBuffer: More memory-efficient for larger buffers when you primarily write and read sequentially
Both implementations share the same interface (BufferInterface), so your code can switch between them without changes.
