Turing Machine with PHP

Finnaly, i found the PHP script for the concept of Turing Machine. Thanks to igorw via gist github

So, this is the turing machine for addition, subtraction, multiplication, and division.

Usage

1. Clone this code
2. Open the file you want to try it.
3. Change the tape array in

tape = []

4. Then Run it

Explanation

1. If you want to test the code, the input tape is in unary. For example if you want to input 3 you must input 111, or 5 is 11111, etc.
2. For the operator is '+' for addition, '-' for substraction, '*' for multiplication, and '/' for division.
3. So, example, if you want to write 4+3 , you must input 1111+111 or in tape array is looks like

tape = ['1','1','1','1','+','1','1','1'];

4. important for division only. Add '#' before and after the number. Example 4/2 is #1111/11###
5. The result is the total numbers of 1 after '_' character.

Contributing

If you want to contribute to adding the concept of turing machine, I am very happy. Add to the main directory. For a turing machine file that can be developed named develope.php Thank you.
