将数字集合转换为数字

Question

If I have a string as : 10 20 3 4 15 6

How can I convert it to individual numbers and store it in a array?

Answer 1

PHP is very clever when dealing with types of variables. You don't need it to be an integer, it can be a string of numbers, and PHP would still treat it as integers when performing operations on them.

If you want to have each element be the numbers separated by spaces, you simply do

$array = explode(" ", "10 20 3 4 15 6");

The output of $array would then be

Array ( 
    [0] => 10
    [1] => 20
    [2] => 3
    [3] => 4
    [4] => 15
    [6] => 6
)
