如
$array3=array("性别"=>"男","姓名"=>"不是女人");
$array4=array("性别"=>"不知道","长相"=>"很帅");
哪么，合并之后，后者将会覆盖前者，这样合并之后就变成了
Array ( [性别] => 不知道 [姓名] => 不是女人 [长相] => 很帅 )
数字型键名，或自动赋值键名，则不会产生覆盖，
如
$array1=array(1,2,3,4,5,6,7);
$array2=array(1,7,8,9,10);
合并之后，为
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 1 [8] => 7 [9] => 8 [10] => 9 [11] => 10 )
