QUIZ: Write a script outputting a multiplication table. No echo, functions etc.

[FractalizeR]

Hello.

 

One respected member of russian PHP forum phpclub.ru DiMA posted a good PHP brain-quiz there. I really liked it so much (after I solved it myself, not before :-) ) that I would like to share it with you here.

 

Write a script, that is printing a multiplication table (example below). The following limitations are implied:

• No PHP functions used at all (both built-in and extensions)
  
• No language constructs for outputting data used at all (like echo, print, var_dump, print_r etc (even inside variable functions). Consider they don't exist
  
• No <?= ?> tags used
  
• No HTML, no JavaScript. Consider script is run from console
  
• No file includes used (require, include, readfile etc.)
  
• Simple stupid output of the whole example at once is cosidered stupid and is not considered as solution
  

 

You can:

• Write your own functions if you like
  
• Use PHP operators and control structures you like
  

 

Output example:

2*2=4
2*3=6
2*4=8
2*5=10
2*6=12
2*7=14
2*8=16
2*9=18
3*2=6
3*3=9
3*4=12
3*5=15
3*6=18
3*7=21
3*8=24
3*9=27
4*2=8
4*3=12
4*4=16
4*5=20
4*6=24
4*7=28
4*8=32
4*9=36
5*2=10
5*3=15
5*4=20
5*5=25
5*6=30
5*7=35
5*8=40
5*9=45
6*2=12
6*3=18

8*3=24
8*4=32
8*5=40
