Help with arrays

[turkman]

Hey i'm having alot of trouble getting arrays working properly What i want to do is call a function called

generateDecks($numberofdecks) Then have it create that many decks - merge them into one array and shuffle them so they are random.

 

Then return the array. In the code below im just trying to print the array but it wont work. Also if i do return $decks

 

how do i call the function like this? $s = array(generateDecks(6));  ??

 

function generateDecks($noofdecks){
$decks = array();
for($i = 0; $i < $noofdecks; $i++){

//assign variables

$i = array( 
1 => "Ace of Hearts",
2 => "2 of Hearts",
3 => "3 of Hearts",
4 => "4 of Hearts", 
5 => "5 of Hearts",
6 => "6 of Hearts",
7 => "7 of Hearts",
8 => "8 of Hearts",   
9 => "9 of Hearts",
10 => "10 of Hearts",
11 => "Jack of Hearts",
12 => "Oueen of Hearts", 
13 => "King of Hearts",    

14 => "Ace of Diamonds",
15=> "2 of Diamonds",
16 => "3 of Diamonds",
17 => "4 of Diamonds", 
18  => "5 of Diamonds",
19 => "6 of Diamonds",
20 => "7 of Diamonds",
21 => "8 of Diamonds",   
22 => "9 of Diamonds",
23 => "10 of Diamonds",
24 => "Jack of Diamonds",
25 => "Oueen of Diamonds", 
26 => "King of Diamonds",   

27 => "Ace of Spades",
28=> "2 of Spades",
29 => "3 of Spades",
30 => "4 of Spades", 
31  => "5 of Spades",
32 => "6 of Spades",
33 => "7 of Spades",
34 => "8 of Spades",   
35 => "9 of Spades",
36 => "10 of Spades",
37 => "Jack of Spades",
38 => "Oueen of Spades", 
39 => "King of Spades",   

40 => "Ace of Spades",
41=> "2 of Spades",
42 => "3 of Spades",
43 => "4 of Spades", 
44  => "5 of Spades",
45 => "6 of Spades",
46 => "7 of Spades",
47 => "8 of Spades",   
48 => "9 of Spades",
49 => "10 of Spades",
50 => "Jack of Spades",
51 => "Oueen of Spades", 
52 => "King of Spades" );

array_merge($decks,$i);
}


print_r($decks);

You're overwriting your for loop $i with an array. Change the name of the array.

[turkman]

i dont understand?

 

The first array will be called  1 the second will be called 2 etc??

 

If i cant do that how can i get it to create a specific number of arrays and merge them?

you can use the double money sign....

function generateDecks($noofdecks){
$decks = array();
for($i = 0; $i < $noofdecks; $i++){

//assign variables

$$i = array( 
1 => "Ace of Hearts",
2 => "2 of Hearts",
3 => "3 of Hearts",
4 => "4 of Hearts", 
5 => "5 of Hearts",
6 => "6 of Hearts",
7 => "7 of Hearts",
8 => "8 of Hearts",   
9 => "9 of Hearts",
10 => "10 of Hearts",
11 => "Jack of Hearts",
12 => "Oueen of Hearts", 
13 => "King of Hearts",    

14 => "Ace of Diamonds",
15=> "2 of Diamonds",
16 => "3 of Diamonds",
17 => "4 of Diamonds", 
18  => "5 of Diamonds",
19 => "6 of Diamonds",
20 => "7 of Diamonds",
21 => "8 of Diamonds",   
22 => "9 of Diamonds",
23 => "10 of Diamonds",
24 => "Jack of Diamonds",
25 => "Oueen of Diamonds", 
26 => "King of Diamonds",   

27 => "Ace of Spades",
28=> "2 of Spades",
29 => "3 of Spades",
30 => "4 of Spades", 
31  => "5 of Spades",
32 => "6 of Spades",
33 => "7 of Spades",
34 => "8 of Spades",   
35 => "9 of Spades",
36 => "10 of Spades",
37 => "Jack of Spades",
38 => "Oueen of Spades", 
39 => "King of Spades",   

40 => "Ace of Spades",
41=> "2 of Spades",
42 => "3 of Spades",
43 => "4 of Spades", 
44  => "5 of Spades",
45 => "6 of Spades",
46 => "7 of Spades",
47 => "8 of Spades",   
48 => "9 of Spades",
49 => "10 of Spades",
50 => "Jack of Spades",
51 => "Oueen of Spades", 
52 => "King of Spades" );

array_merge($decks,$$i);
}


print_r($decks);

 

try it out...im not sure how well it will work....although i think this would fall under really bad practices...

 

Cheers! :-)

 

[turkman]

I can't try it out until i get home. However if it is considered bad practices. Could you recommend a good way of doing it?

I tried the following but all that the print_r($decks) displays is

 

Array() 

 

What am i doing wrong?

 

<?PHP

//loop cards

function generateDecks($noofdecks){
$decks = array();


//assign variables

$deck = array( 
1 => "Ace of Hearts",
2 => "2 of Hearts",
3 => "3 of Hearts",
4 => "4 of Hearts", 
5 => "5 of Hearts",
6 => "6 of Hearts",
7 => "7 of Hearts",
8 => "8 of Hearts",   
9 => "9 of Hearts",
10 => "10 of Hearts",
11 => "Jack of Hearts",
12 => "Oueen of Hearts", 
13 => "King of Hearts",    

14 => "Ace of Diamonds",
15=> "2 of Diamonds",
16 => "3 of Diamonds",
17 => "4 of Diamonds", 
18  => "5 of Diamonds",
19 => "6 of Diamonds",
20 => "7 of Diamonds",
21 => "8 of Diamonds",   
22 => "9 of Diamonds",
23 => "10 of Diamonds",
24 => "Jack of Diamonds",
25 => "Oueen of Diamonds", 
26 => "King of Diamonds",

excellent. Thanks,
