■配列生成：$aryOut=range(n,m)とshuffle(array)
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
    [7] => 8
    [8] => 9
    [9] => 10
)
8 6 9 7 5 3 4 1 2 10 
Array
(
    [0] => 8
    [1] => 6
    [2] => 9
    [3] => 7
    [4] => 5
    [5] => 3
    [6] => 4
    [7] => 1
    [8] => 2
    [9] => 10
)
■配列キーのランダム取得：$aryOut = array_rand(array,num)
Array
(
    [0] => cherry
    [1] => banana
    [2] => orange
)
■可変変数の配列作成：$aryOut = compact(varname1 [,varname2],array)
Array
(
    [zip] => 228
    [pref] => 神奈川県
    [city] => 横浜市
)
■配列から可変変数の作成：extract(array [,flags [,prefix]])
