Question

I have a variable called

  $core

I also have 3 other variables called

 $one, $two, $three

I need to (many times) display a random combination of these where $core is always included and 1 of the 3 other variables are included once either before or after:

eg:

 $two $core
 $core $one
 $three $core
 $core $two

I’m unsure how to get this randomness working with PHP?
A push in the right direction would be greatly appreciated.

thx

Answer 1

Hold the three variables in an array. Then call rand() between 0 and 1 to determine whether an array value or $core should be printed first. At the same time, call a random value from the array

// Array of the three vars
$arr = ($one, $two, $three);
// If 0 is chosen, print an array value then $core. 
// Otherwise print $core than an array value
echo rand(0, 1) == 0 ? $arr[rand(0,2)] . " " . $core : $core . " " . $arr[rand(0,2)];
