I suggest you use an array instead of individual scalar variables, making things much simpler:

$var = array();
$var[1] = 'foo';
$var[2] = 'bar';
$var[3] = 'fubar';
$num = rand(1,3);
echo $var[$num];

However if you did need to use scalar variables for some reason, instead of arrays, you could do so using braces:

$var1 = "something";
$var2 = "something else";
echo ${'var'.rand(1,2)};
