Randomize and print 6 variables.

[sauce]

I have 12 variables var1-var12 and I'm trying to display them on the page like like this:

var3, var11, var5, var9, var12, var10

I want it to pull 6 out of the 12 and randomize them everytime the page is refreshed.

I keep running into the randomizing problem... I keep getting errors and only can get them to display this way.

var1, var2, var3, var4, var5, var6....

Any suggestions?

maybe try creating an array with rand numbers in it from 1-12

something like array[4,9,10,3,12,6]
you'll need a loop to create it then have a check to make sure that numbers arn't repeated.

Sarah is correct about arrays. Something simple like this should do:

$numbers = range(1,12);
shuffle($numbers);

for ($i=0; $i<6; $i++)
{

echo $numbers[$i]."<br>";
}

here I made it:

$ar=range(1,12); //created an array with values 1-12
shuffle($ar); // shuffles an array
for($i=1;$i<=6;$i++) { $ar2[]=${'val'.$ar[$i]}; } //creates additional array with 6 random elements from $valN
echo implode(',',$ar2); // prints it separated with comma

thought I had to make it 4 lines code because it should be separated with commas

oops, dreamcatcher wrote it faster %) but the wrong way. as I understood it should show the values of $val1-$val12 instead of just random numbers.

so use my code.
