PHP：将字符串转换为数组

Question

I have an input string that has the following value:

"[2018-05-08][1][17],[2018-05-08][2][31],[2018-05-08][3][40],[2018-05-08][4][36],[2018-05-09][1][21]"

I want to convert this into a php array that looks something like this:

$date=2018-05-08;
$meal=1;
$option=17;

can someone help me please !

Answer 1

Simple parser for You

$arr1 = explode (",","[2018-05-08][1][17],[2018-05-08][2][31],[2018-05-08][3][40],[2018-05-08][4][36],[2018-05-09][1][21]"); // making array with elements like : [0] => "[2018-05-08][1][17]"
$arr2;
$i = 0;
foreach($arr1 as $item){
    $temp = explode ("][",$item); // array with elements like [0] => "[2018-05-08", [1] => "1", [2] => "21]"
    $arr2[$i]['date'] = substr( $temp[0], 1 ); // deleting first char( '[' )
    $arr2[$i]['meal'] = $temp[1];
    $arr2[$i]['option'] = substr($temp[2], 0, -1); // deleting last char( ']' )
    $i++;
}
