[RESOLVED] array in a function: problem

[choubix]

hello

I have a function called random_draw() stored in functions.tpl.php

random_draw() returns 4 sorted numbers of an array of 16 numbers.

in lucky.php I then include functions.tpl.php and call random_draw()

now I would like to retrieve the array and convert it to a string so I can store it in the table.

can someone help me please? the function seems to work alright by i am not lucky at all extracting the array and converting it to a string.

thanks

here is the function random_draw()

function random_draw()
{
$numbers=array(01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16);

//Get 4 unique random keys from $numbers array.
$rand_keys = array_rand($numbers, 4);

//if you want to sort the random keys
sort($rand_keys);

//print out the random numbers using the
//random keys.
foreach ($rand_keys as $k=>$v) {
return $numbers[$v];
}
}

If the draw is 01324476 (4 joined numbers) I need this string to be inserted in the table. (the 0 in 01, 02, 03 ... is important)

hope someone can help me out 🙂

thanks

You need to construct a string, not return on the first iteration of your foreach loop:

function random_draw()
{
    $numbers = range(1, 16);

// Get 4 unique random keys from $numbers array.
$rand_keys = array_rand($numbers, 4);

// If you want to sort the random keys.
sort($rand_keys);

// Construct string of joined numbers.
$draw = '';
foreach ($rand_keys as $rand_key)
{
    $draw .= str_pad($numbers[$rand_key], 2, '0');
}
return $draw;
}

hi !

thanks for the help. 🙂

It's almost perfect.
I noticed the function return 10, 20, 30.... instead of 01, 02, 03, 04...
and i need to store the values that way.

I checked the function str_pad but i dont get whether it's possible or not...

thanks
