Those arrays have to be perfectly parallel for this to work. In other words if regels means regulations then they have to be in the same place in the corresponding arrays. Right now regulations is the fourth word in the Qword array, but regels is the fifth in the answer array. I'm a little bit handicapped by not understanding the language, but they don't look parallel to me.

I'll need to look at it a little bit more later when I have more time, but it won't work unless the arrays are perfectly parallel.

Ok, here's an example using 20 words and answers. I made a few changes: I used the round() function to determine the percent, I changed the way the asked variable was storing the numbers by adding spaces around the number so that "10" would be stored as " 10 " and then searched it looking for the number surrounded by spaces so that it wouldn't mistake 10 for 1 or 0, and I set the upper limit of the random generator as count($Qword-1) so that it will change automatically as you edit the list. Since arrays start counting from 0, an array with 20 strings will have the first element as 0 and the last as 19. In other words the last word in the array will be one less than the total number returned by count() since arrays start from 0 and not 1.

You will still need to edit these arrays to make them parallel. I can't because I don't know the language, but I'm pretty sure they don't match correctly. The first word in the answer array must be the correct translation for the first word in the Qwords array and so on.

Depending on how php is setup it may or may not add a backslash before any single quotes you have in your words when they are passed to the evalution form. If you want to prevent them from showing up onscreen when echoing them surround them with the stripslashes function (echo stripslashes($q) for example) It might be best to avoid the quotes entirely if you can.

Another potential problem is the use of special character like the umlaut (I think that's the correct name for the two little dots over a vowel anyway). Unless you are sure that your user will enter those character exactly as they are in your answer it might be best to avoid them.

If the script times out when running the full lists you may have to break it down into 4 or 5 quizzes of 20-25 words each, but I was able to run the full list of 115 without timing out, so I don't think it will.
