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.

Random Data Library
The library is easy to get up and running quickly. It is suitable for generating random bytes or strings from a given character set. It is possible to generate arrays of arbitrary depth of nesting as well as files with large data structures
Install
Via Composer
Usage
Generation random strings
This simple functions placed in file RandomStr.php and have have no dependencies
- genRandomStr($len)
- genRabdomBytes($bytes_cnt)
- setChars(list of values from which the result will be generate)
It is easy to understand from the examples below
Generation random Arrays
The random array generation class RandomArray are extended of RandomStr.
Simple examples:
The generation of random arrays occurs in memory, so with a large number of elements (100,000 or more) it may work slowly if using non-simple models.
But, when using simple numeric keys (1,2,3...n) and simple values range 0-65535, generation time of array 1 million elements (with depth of nested 2-3 levels) is less than 1 second.
See example:
What is Generation models?
Generation random keys and values can use 4 models:
- 0 Simple model - Is the fastest, 1,2,3..n for keys and 0-65535 for values.
- 1 Numeric range model - Use mt_rand(min,max) for random keys or values.
- 2 RandomStr model - Use function genRandomStr for gen. keys or values.
- 3 User function - Use user defined function for generation keys or values.
These models are set as follows:
-
0 Simple model
-
1 Numeric range model
-
2 RandomStr model (See description of the function genRandomStr)
- 4 User function model
