Need help converting this Python to PHP

Postby Nib » Thu Mar 27, 2014 12:53 pm

Well, I am a total Python Newbie but know PHP very well, I wanted to create a website that would help people to generate Word crosswords, hence after a little web search I found this Python Code which I need help in converting to PHP> I tried myself but failed as I know nothing about Python, I also tried an online conversion tool, but without any luck, so if anyone here can help me convert the following code to PHP, it will be highly respected. Heres the code:

Code: Select all
import random, re, time, string
from copy import copy as duplicate
 
class Crossword(object):
    def __init__(self, cols, rows, empty = '-', maxloops = 2000, available_words=[]):
        self.cols = cols
        self.rows = rows
        self.empty = empty
        self.maxloops = maxloops
        self.available_words = available_words
        self.randomize_word_list()
        self.current_word_list = []
        self.debug = 0
        self.clear_grid()
 
    def clear_grid(self): # initialize grid and fill with empty character

        temp_list = []
        for word in self.available_words:
            if isinstance(word, Word):

            else:

What part of it is giving you trouble?
What part don't you understand?

I highly doubt anyone is gonna translate the whole thing to PHP for you.
Friendship is magic!
