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 php-config-loader
PHP Config Loader
Load configuration from JSON, PHP, YAML, and TOML files with environment variable substitution.
Requirements
- PHP 8.2+
- ext-yaml (optional, required for YAML file support)
Installation
Usage
Loading a Single File
PHP config file (app.php):
JSON config file (database.json):
Dot-Notation Access
Typed Getters
Checking Key Existence
Environment Variable Substitution
Config values containing ${VAR} are resolved from environment variables at load time. Use ${VAR:default} to provide a fallback.
Loading a Directory
Load all .php, .json, .yaml, .yml, and .toml files from a directory. Each file's basename (without extension) becomes a top-level key.
Deep Merge
Combine two configurations with deep merging. Values from the second config override the first; nested arrays are merged recursively.
Flattening Nested Config
Convert nested configuration into a flat associative array with dot-notation keys.
Configuration Validation
Validate config values against a set of rules. Rules are pipe-separated.
Supported rules: required, string, int, bool, float.
