Convert Array to json with json_encode - php

Question

I have an array with the output (print_r):
Array
(
[a] => 706
[b] => 194
[c] => 164
[d] => 44
[e] => 42
[f] => 41
[g] => 40
[h] => 38
[i] => 13
)
I need to convert it to a json of this format:
[{"name":"a","value":706},{"name":"b","value":194},{"name":"c","value":164},{"name":"d","value":44},{"name":"e","value":42},{"name":"f","value":41},{"name":"g","value":40},{"name":"h","value":38},{"name":"i","value":13}]
This is what I've tried but I'm just guessing and not getting the right output :
echo '[';
foreach($sortedArray as $key => $value) {
echo $dataTable = json_encode(array(
'name' => $key,
'value' => $value
), JSON_NUMERIC_CHECK);
};
echo ']';

Answer 1

$keyPair = array();
foreach($sortedArray as $key => $value) {
$keyPair[] = array('name' => $key, 'value' => $value);
}
echo json_encode($keyPair);

Try this:
$data = array(
'a' => 234, 'b' => 2343, 'c' => 23423, /* etc. */
);
$new_data = array();
foreach ($data as $k => $v) {
$new_data[] = array(
'name' => $k, 'value' => (number)$v
);
}
print json_encode($new_data);

Answer 3

Code
$arr = array(
'a' => 706,
'b' => 194,
'c' => 164,
'd' => 44,
'e' => 42,
'f' => 41,
'g' => 40,
'h' => 38,
'i' => 13);
$map_arr = array();
foreach ($arr as $k => $v)
$map_arr[] = array('name' => $k, 'value' => intval($v));
print json_encode($map_arr);
Result
[{"name":"a","value":706},{"name":"b","value":194},{"name":"c","value":164},
{"name":"d","value":44},{"name":"e","value":42},{"name":"f","value":41},
{"name":"g","value":40},{"name":"h","value":38},{"name":"i","value":13}]
