echo "Get key1 value:". $val. "
";
//Replace data
$mem->replace (' key1′, ' This is replace value ', 0,);
$val = $mem->get (' key1′);
echo "Get key1 value:". $val. "
";
//save array
$arr = Array (' AAA ', ' BBB ', ' CCC ', ' ddd ');
$mem->set (' key2′, $arr, 0, 60);
$val 2 = $mem->get (' key2′);
echo "Get Key2 value:";
