how to store multiple values for one key in php array [closed]

Answer 1

To directly answer your question, no. PHP arrays can only contain one set of data for the key.

You need to use a multidimensional array, where the value of a key is an array with keys and values, e.g.:

$array = array
  (
    "bob" => array
                    (
                      "height" => "6.0",
                      "age" => "21",
                    ),
    "joe" => array
                    (
                      "height" => "5.9",
                      "age" => "35",
                    )
  );
