php - How to explode vaules in $_GET['']=1#5#6 in php?

Question

Hi in my url i have variables stored in ../index.php?cat=1#5#8 in so on how to separate them using explode function so out put could be

arr[0]=1
arr[1]=5
arr[2]=8

Answer 1

试试explode喜欢

$arr = explode("#",$_GET['cat']);

但正如@Bora 所说#，剩余的字符串可能不会被发送，所以最好使用 '_' 代替 '#' (1_5_8_....) 并且可以像

$arr = explode("_",$_GET['cat']);

Answer 2

尝试这个：

$array=$_GET['cat'];

$result = explode("#",$array);
