两个数组的键名都是数字的话，第二个数组会附加到第一个数组后。 array_merge() 键名是相同的字符的话，则后面的数组会将前面的数组替换。 array_merge_recursive() 键名是相同的字符，则值会被合并到该字符为key的数组中。
$array1=array(
'0'=>array('id'=>1,'name'=>'one'),
);
$array2=array(
'0'=>array('id'=>2,'name'=>'two'),
);
$arr=array_merge($array1,$array2);
print_r($arr);
Array
(
[0] => Array
(
[id] => 1
[name] => one
)
[1] => Array
(
[id] => 2
[name] => two
)
) |
