Could you relay which type of PHP5 Features we need to modify to make this work with php4? I don't expect you to list this exact coding, just kinda pass along which features will not work in less than php5 so we can look at recoding those features?
Thanks,

Hi,
I used PHP5 syntax throughout, like public and protected and __construct.
That will be easy to change. Then, I think you will need a few & to make sure you get references to objects instead of copies.
I think that would be all you need to make it work on PHP4.
Let me know if you have any problems! |

I have tried to cconvert this PHP5 to PHP4 by changing the constructor to the function with the same class name, $this->solver = new Solver(); to $solver = new Solver(); and removed all the function access types but still it is giving the following error. Could you please have a look it once and let me know where I have gone wrong and if possible can you please also give PHP4 version for this.

Thanks in advance

Hi,
I took a quick look also, it is a bit of a problem because I do not have a PHP 4 system. Anyway, just doing the changes you said is not enough. It is also necessary to assign by reference all classes. I will take a look at it this weekend, and let you know. |

OK. I did a PHP4 version. It turned out to be far from trivial.
Because the package was using complex arrays of objects and a lot of foreach, using references all over did not help. Therefore I rewrote part of the package to use arrays with numbers (which indicated the number-fields in the array) instead of arrays of number-field objects.
You can find the complete set of scripts needed in the sudoku4 subdirectory. |

Hi,
I think you must ask the webmaster, Manuel Lemos to do this.
By the way, you should not have had this error message. Must be sometihng particular with your path settings? |
