Signs

I have 3 signs in my world and an array with to strings (test and test2). How can I randomly set the strings on the signs? Only one string with one sign. So one sign keeps empty

 

the following code will assign one of the two random strings to a one of the three random signs.

PHP:

$string = $stringArr[mt_rand(0,1)];
$signTile = $tileArr[mt_rand(0,2)];
$signTile->setText($string);


 

Lol. This only sets a random value of the array to the sign. Please read the question carefully

 

Look at what @jasonwynn10 posted carefully. You're making it sound like you know what you're doing, so why ask for help?
