[SOLVED] array_rand

[ki]

okay basically my problem is that my info isnt displaying.

my code:

$aFriends = array($p1->friends);
$rFriends = array_rand($aFriends, 6);
for ($i=0; $i<=6; $i++) {
echo $aFriends[$rFriends[$i]];
}

 

$p1->friends is pulled from a mysql db and has for example: 1, 3, 4, 5, 7, 9, 10, 15

 

what I wanted it to do was pull 6 random numbers from the array and its not doing that :/

any help would be appreciated

Hello ,

 

Modified your code with the following,

 

$aFriends = array($p1->friends);
$rFriends = array_rand($aFriends, 6);
for ($i=0; $i<6; $i++) {
echo $rFriends[$i];
}

 

Hope this will solve your problem.

Regards

thanks for the reply, but unfortunatly it doesnt work, i have no clue why.

ok. what is the array format you are having for which random results needs to be found..

 

Are you getting any error messages?

[ki]

okay my array would end like this:

$aFriends = array(1,2,3,4,5,6,7);
$rFriends = array_rand($aFriends, 6);
for ($i=0; $i<6; $i++) {
echo $rFriends[$i];
}

I want it to randomly choose the numbers that are found in the array.

so for example it would ed out like:

5,1,7,3,2,4

and so on

 

and no im not having any error issues

[ki]

would it actually be possible to add each random selection from the $aFriends array and make a new array entirely and implode it?

[ki]

can someone help me with this? im still getting nothing from different alterations to my code, I have no idea why its messing up like this

[ki]

okay with a bit of tampering i figured out how to do it:

 

srand((double)microtime()*1000000);
$aFriends = explode(",", $p1->friends);
foreach ($aFriends as $key => $term) {
$aFriends[$key] = $term;
}
$rFriends = array_rand($aFriends, 2);
echo $aFriends[$rFriends[0]];
echo $aFriends[$rFriends[1]];

hope that helps someone in the future
