在陣列上按值
將元素推送到陣列有兩種方法:array_push
和 $array[] =
該 array_push 這樣使用:
$array = [1,2,3];
$newArraySize = array_push($array, 5, 6); // The method returns the new size of the array
print_r($array); // Array is passed by reference, therefore the original array is modified to contain the new elements
此程式碼將列印:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 5
[4] => 6
)
$array[] =
使用如下:
$array = [1,2,3];
$array[] = 5;
$array[] = 6;
print_r($array);
此程式碼將列印:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 5
[4] => 6
)
