如何分割形式[“1”，“2”，“3”]的数据并在数组中存储为[1,2,3]在PHP中

How to split the data of the form ["1","2","3"] and store in array as [1,2,3] in PHP?

I need this data in order to get or fetch data from a mysql table which is having data as id 1 data red, id 2 data blue. so that i need the data to be converted to 1 2 3 so that I can give it in query to fetch the data.

Please someone help me thanks.

Something like this will do , Run this after your while .

$int_arr = array_map('intval',$your_returned_array);

EDIT:

ok am sorry it is column value in table it is totally a string which i have to split as numbers

Do like this..

$str= '["1","2","3"]';
preg_match_all('/"(.*?)"/', $str, $matches);
print_r(array_map('intval',$matches[1]));

OUTPUT :

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
