php数组合并并转换为json

Question

I have two arrays (below). Is it possible to convert them into json string?

Array
        (
            [0] => size
            [1] => color
        )
Array
        (
            [0] => L
            [1] => Black
        )

Output structure should be:

[
   {"name":"size","value":"L"},
   {"name":"color","value":"Black"}
]

Thanks!

Answer 1

Sure:

$array1 = array('size', 'color');
$array2 = array('L', 'Black');

$jsonArray = array();
foreach (array_combine( $array1, $array2 ) as $name => $value) {
    $jsonArray[] = array('name' => $name, 'value' => $value);
}

echo $json = json_encode($jsonArray);

This gives you

[{"name":"size","value":"L"},{"name":"color","value":"Black"}]
