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.

Raw random values example
Filling string by template
Let's we have a string with a pair of variable words in it. We will fill this fields with random values:
Let's make it a little more complicated:
Generators. Creating csv
Generators. Filling database and more
First of all, you can define your data manually:
If your database is too big and you want to get it fast, you can get it from sql SHOW CREATE TABLE command:
If you want it VERY fast and you don't care much about plausibility, you can fill all database tables (if any field is NULL possible, its value will be NULL with about 50% probability):
Currenty only this data types supported (feel free to ask for extanding the list or make your own contribution to the project):
- (tiny|small|medium|big)int
- decimal
- varchar
- (tiny|medium|long)text
- enum
- set (only one of available values for the row will be generated, i.e. one OR two OR three, but not one,two or one,three
- datetime/date/time/year/year(4)/year(2)
Data dependency
In real life data is dependant. Birth must be before death, sunrise time before sunset time, salary is calculating from worked hours, hourly rate, fines and so on.
This library can generate data dependant from other object attributes (for example, hired date dependant from birth date).
If you have dependencies between different objects (Authors and Books), it can be little tricky, but something about this:
Or simplier, if you test with 100 authors:
Data dependency. Nested datasets
Another way to declare dependency is nested datasets
Filling forms

Main Objects
RandData Fabric
Creates RandDataSet objects
RandData Set
Generates one random value. Atomic piece of data, may be simple (boolean, number or char) or complex, for example PersonName Object (FirstName + MiddleName + LastName) or AviaTicket Order Object (departure information, route, passenger list, status information and so on)
Tuple
Manages list of datasets. Can add dataset from PHP object or from string. Generates array of random values
RandData Generator
Manages generation process. Produces amount of random datasets (array of arrays of random values).
RandData Formatter
Buids data stream into something useful. Now it can be csv file, sql INSERT commands or JSON array.
DataSet options
All DataSet can be created from string identificator ("boolean", "string", "integer" and so on):
There also may be an optional params:
Params seperated by semicolon and name/value pairs separated by equal sign:
Value may be an array item, its item seperated by comma:
Counter
Simple counter. Generates number sequence inside string or as number. When calling by Generator object, it is incremented automatically. When calling direct or by Tuple object, you need to set counter value manually
ID
counter, cnt
Params
- tpl, template: When setted, it generates string with counter (for example, template "user_#" turns to { user_1, user_2, user_3, ... }. When missed, then usual unsigned integer will be returned { 1, 2, 3, ... }
- start: Default start value. For example, you set generator's amount property to 20, and start counter property setted to 100, then you get values { 100, 101, 102, ..., 119 }
