FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

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.

Please rate this library. Is it a good library?

Informations about the package spacetime

SqrtSpace SpaceTime for PHP

Memory-efficient algorithms and data structures for PHP using Williams' √n space-time tradeoffs.

Paper Repository: github.com/sqrtspace/sqrtspace-paper

Installation

Core Concepts

SpaceTime implements theoretical computer science results showing that many algorithms can achieve better memory usage by accepting slightly slower runtime. The key insight is using √n memory instead of n memory, where n is the input size.

Key Features

External Sorting: Sort large datasets that don't fit in memory
External Grouping: Group and aggregate data with minimal memory usage
Streaming Operations: Process files and data streams efficiently
Memory Pressure Handling: Automatic response to low memory conditions
Checkpoint/Resume: Save progress and resume long-running operations
Laravel Integration: Deep integration with Laravel collections and queries

Quick Start

Examples

Basic Examples

See examples/comprehensive_example.php for a complete demonstration of all features including:

Memory-efficient arrays and dictionaries
External sorting and grouping
Stream processing
CSV import/export
Batch processing with checkpoints
Memory pressure monitoring

Laravel Application

Check out examples/laravel-app/ for a complete Laravel application demonstrating:

Streaming API endpoints
Memory-efficient CSV exports
Background job processing with checkpoints
Real-time analytics with SSE
Production-ready configurations

See the Laravel example README for setup instructions and detailed usage.

Performance Considerations

Chunk Size: The default √n chunk size is optimal for most cases, but you can tune it:
Compression: Enable for text-heavy data, disable for already compressed data:
Storage Location: Use fast local SSDs for external storage:

Framework Integration

Laravel

Symfony

For a complete Symfony integration example, see our Symfony bundle documentation.

Troubleshooting

Out of Memory Errors

Reduce chunk size:
Enable more aggressive memory handling:
Use external storage earlier:

Performance Issues

Check disk I/O speed
Enable compression for text data
Use memory-based external storage:

Checkpoint Recovery

Requirements

PHP 8.1 or higher
ext-json
ext-mbstring

Optional Extensions

ext-apcu for faster caching
ext-redis for distributed operations
ext-zlib for compression
