Hangman Source Code: PHP

0

By Graphix on Mar 12th, 2010 10:18 pm

Hey everybody,

Lately I have written the game Hangman in many different languages (C, JavaScript, Java and PHP so far). Here is the code snippet for PHP! It uses a words file, on the bottom of this post you will see a small example of a few words. The source code for other languages can be found here on DaniWeb and on my new website: [URL snipped].

You can adjust the words file in the getWord() function (line 21). The words need to be separated by a |. Words files can be found can be found here . By default, the images made by Symbol Webdesign will be used. If you want to change the imagesource, adjust the HTML part.
