[Sheau Wei]

I am using php version 4.3.3.
The below was my pagination code.
My problem is that when i run this code in my computer, i wall fail because of the hyperlink of the pagination not function when i click it. But when i run in other people computer, It was no problem at all. I wonder to know what wrong to my coding . Is it different version of php also reflect the output?
