Question

id:10 Ivysaur Level:5

存储在$ _POST [A]

的旁边

我正在尝试抓住id（所以10）和名称（在本例中是Ivysaur）并且我想将它们存储在会话变量中。但在我存储它们之前，我试图将它爆炸，因此可以将它分成几部分

$phoneChunks = explode("-", $_POST[A]);
echo "Raw Phone Number = $rawPhoneNumber <br />";
echo "First chunk = $phoneChunks[0]<br />";
echo "Second chunk = $phoneChunks[1]<br />";
echo "Third Chunk chunk = $phoneChunks[2]";

我正在

Raw Phone Number =
First chunk = Id:10 Ivysaur Level:5
Second chunk =
Third Chunk chunk =

我做错了什么???

Answer 1

preg_match("/id:(\d+) (.+?) Level:(\d+)/",$_POST['A'],$match);
list(,$id,$name,$level) = $match; // don't forget extra , at beginning of list!

现在，您可以使用变量$id，$name和$level来执行任何操作。祝你好运：）

Answer 2

当你的字符串中没有短划线时，你试图在短划线上爆炸。试试这个：

$phoneChunks = explode(" ", $_POST[A]);

Answer 3

试试这个：

$chunk = explode(" ", $_POST['A']);

它应该产生这样的东西：

Array
(
    [0] => id:10
    [1] => Ivysaur
    [2] => Level:5
)

Answer 4

我做错了什么???

您没有逃避$_POST['A']

$phoneChunks = explode(' ',hmtlentities($_POST['A']));
