$array1 = array(

结果如下：
array(4) {
[0]=>array(3) {
["id"]=>int(5)
["name"]=>string(3) "Cos"
["age"]=>int(16)
}
[1]=>array(3) {
["id"]=>int(5)
["name"]=>string(3) "Cos"
["age"]=>int(14)
}
[2]=>array(3) {
["id"]=>int(8)
["name"]=>string(5) "Apple"
["age"]=>int(18)
}
[3]=>array(3) {
["id"]=>int(8)
["name"]=>string(3) "Bed"
["age"]=>int(17)
}
}
