What is the algorithm solve this in FPDF?

I am going to generate report by using FPDF.

My Problem Like this the horizontal data is too long to display in A4 or A3 :

V  ->  H1 ->   H2 ->    H3............>    HTotal
v1 ->   1       2       3   ..........>    1+2+3+..n
v2 ->   1       2       3    .........>    1+2+3+..n
v3 ->   1       2       3    .........>    1+2+3+..n
.......................................
Vtotal  1*n     2*n     3*n...........>    (1+2+3+..n)*n

Example

V  ->  H1  ->  H2->  H3 -> H4 ->   TOTAL
v1    1       2      3     4        10
v2    1       2      3     4        10
v3    1       2  开发者_运维技巧    3     4        10
v4    1       2      3     4        10 
VT   4        8      12    16      40

so my PDF can be output like (split the display pages)

V  ->  H1 ->  H2
v1    1        2  
v2    1        2   
v3    1        2    
v4    1        2  
VT    4        8   

V  -> H3->H4 
v1    3     4  
v2    3     4 
v3    3     4    
v4    3     4   
VT   12    16 

V  ->  TOTAL
v1     10
v2     10
v3     10
v4     10 
VT     40

so even if the data it too long I still got the data display.

Could anyone help me:

• solve this problem ?
  • or suggest to me the solution using FPDF?
  • or suggest an algorithm in PHP?

Of Course that you cant put 100 columns at a A4, but to by more space, you may like to write columns vertically, (just column headers), as i see data that you are putting at your columns are numbers, so the only issue is header of it, like TOTAL, you may write it vertically like: T O T A L
