Answer 1

Not sure quite what your question is here (please clarify by editing your post).
Your output does not look like a Php array. More like JSON.
When you say remove indexes, could this be from having non sequential 0 counted indexes?
See below:
<?php
$people =
[
[
'name'=>'fred',
'family'=>'flintstones'
],
[
'name'=>'barney',
'family' => 'rubble'
],
[
'name'=> 'wilma',
'family' => 'flintstones'
]
];
var_dump(json_encode($people));
unset($people[1]);
var_dump(json_encode($people));
var_dump(json_encode(array_values($people)));
Output:
string(116) "[{"name":"fred","family":"flintstones"},{"name":"barney","family":"rubble"},{"name":"wilma","family":"flintstones"}]"
string(88) "{"0":{"name":"fred","family":"flintstones"},"2":{"name":"wilma","family":"flintstones"}}"
string(80) "[{"name":"fred","family":"flintstones"},{"name":"wilma","family":"flintstones"}]"
You can use array_values to reindex arrays before encoding to JSON to 'remove' those indexes, and turn into a list of objects.

Answer 2

json_encode() : Returns the JSON representation of a value
echo json_encode($a);

Answer 3

Question
Your array already has the correct dimensions, just run json_encode($array); over it and you will have the result you're looking for.
If you want to use an associative array, you'll have to be a bit more creative:
$result = [];
foreach($array as $index) {
$result[$index['firstName']] = $index;
}
var_dump($result);
Result:
Array
(
[Hadi] => Array
(
[firstName] => Hadi
[lastName] => Pratama
[age] => 22
)
[Jefri] => Array
(
[firstName] => Jefri
[lastName] => Ronaldo
[age] => 21
)
[Rizky] => Array
(
[firstName] => Rizky
[lastName] => Aulia
[age] => 20
)
)
