PHP - 使用文本字符串中的键创建数组

Question

I have simple text string, it is looking like that:

30143*1,30144*2,30145*3,30146*5,30147*5

And i have to transform this text string to array with this structure:

Array ( [0] => Array ( [product] => 30143 [qty] => 1 ) [1] => Array ( [product] => 30144 [qty] => 2 ) [2] => Array ( [product] => 30145 [qty] => 3 ) [3] => Array ( [product] => 30146 [qty] => 4 ) [4] => Array ( [product] => 30147 [qty] => 5 ) )

Is it even possible and if so how?

I found this:

$myString = "9,[e-mail],8";
$myArray = explode(',', $myString);
print_r($myArray);

But this is only creating the array with no keys and wtih example there is no way to get the qty key with *.

Thanks in advance!

Here you go. You need to iterate through all the 30143*1 items. array_map do this job for you.

function getPieces($val) {
    $pieces  = explode('*', $val);
    return ['product' => $pieces[0], 'qty' => $pieces[1]];
}

$str = '30143*1,30144*2,30145*3,30146*5,30147*5';
$result = array_map('getPieces', explode(',', $str));

var_dump($result);

OUTPUT:

array (size=5)
  0 => 
    array (size=2)
      'product' => string '30143' (length=5)
      'qty' => string '1' (length=1)
  1 => 
    array (size=2)
      'product' => string '30144' (length=5)
      'qty' => string '2' (length=1)
  2 => 
    array (size=2)
      'product' => string '30145' (length=5)
      'qty' => string '3' (length=1)
  3 => 
    array (size=2)
      'product' => string '30146' (length=5)
      'qty' => string '5' (length=1)
  4 => 
    array (size=2)
      'product' => string '30147' (length=5)
      'qty' => string '5' (length=1)
