How to get Table field names at top of result array - php

Question

Here is my Sample table:
Here is My Query:
SELECT * FROM table
Result for above query is:
Array
(
[0] => Array
(
[id] => 1
[name] => a
[country] => x
)
[1] => Array
(
[id] => 2
[name] => b
[country] => y
)
)
I need to get the field names in the first element of the array.
Expected result array is:
Array
(
[0] => Array
(
[id] => id
[name] => name
[country] => country
)
[1] => Array
(
[id] => 1
[name] => a
[country] => x
)
[2] => Array
(
[id] => 2
[name] => b
[country] => y
)
)
How can I modify the Query to get this result?
Thanks in advance...

Answer 1

Display issues should generally be dealt with in application code, not SQL queries. If you have your values in an array (called $results, say), you can use this code to add the desired entry:
array_unshift($results, array_combine(array_keys($results[0]), array_keys($results[0])));
print_r($results);
Output:
Array
(
[0] => Array
(
[id] => id
[name] => name
[country] => country
)
[1] => Array
(
[id] => 1
[name] => a
[country] => x
)
[2] => Array
(
[id] => 2
[name] => b
[country] => y
)
)

SELECT 'id' id, 'name' name, 'country' country
UNION ALL
SELECT id, name, country FROM table
ORDER BY 'id' != id

Answer 3

One way to do it with array_keys, array_combine and array_unshift. If I were you I will get the SQL result as $array variable and do some processing on php side like below on query side.
<?php
$array = [['id'=>1,'name'=>'a','country'=>'x'],['id'=>1,'name'=>'b','country'=>'y']];
$keys = array_keys($array[0]);
$first = array_combine($keys,$keys);
array_unshift($array,$first);
print_r($array);
?>
