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 fixed-array-functions
Fixed Array Functions
SplFixedArrays are an implementation of a traditional, bounded array in the PHP standard library.
While they require manual resizing, they're significantly faster than regular arrays or collections when working with large sets of data.
Requirements
Currently, requires PHP 8.4 or above, and Laravel 12+.
Installation
You can install the package via Composer:
Quick Start
Fluent interface
FixedArray is best used with its fluent interface. If you're familiar with Illuminate collections, you'll feel right at home. Provide it an SplFixedArray to get started, or a standard array or collection that will be automatically converted.
Static methods
You aren't forced to use the fluent interface and can access methods directly by calling them. This is useful if you only need to do one or two operations on a fixed array.
Real-World Examples
Processing Large Datasets
Data Aggregation
Conditional Transformations
Partitioning Data
Performance Benefits
SplFixedArray offers significant performance advantages over standard PHP arrays for large datasets:
- Memory Efficiency: Uses approximately 50% less memory than standard arrays
- Faster Access: Direct memory access without hash table overhead
- Predictable Performance: O(1) access time for all operations
When to use SplFixedArray:
- Working with large datasets (10,000+ elements)
- Memory-constrained environments
- Performance-critical array operations
- Known array size at creation time
When to stick with regular arrays/Collections:
- Small datasets (< 1,000 elements)
- Dynamic sizing with frequent additions/removals
- Need associative keys or complex key types
