PHP Transform multiple objects into one array - php

Question

Whilst trying to transform multiple objects and put them into one array I unfortunately get a array-in-array result.
The objects I would like to transform:
array(2) {
[0]=>
object(stdClass)#104 (1) {
["name"]=>
string(4) "Paul"
}
[1]=>
object(stdClass)#105 (1) {
["name"]=>
string(5) "Jenna"
}
}
My PHP:
for ($i=0; $i < count($readers) ; $i++) {
$json = json_encode($readers[$i]); // 1
$data = json_decode($json, TRUE); // 2
$arr = array();
array_push($arr, $data); // 3
}
The outputs:
// 1
{"name":"Paul"}{"name":"Jenna"}
-
// 2
Array
(
[name] => Paul
)
Array
(
[name] => Jenna
)
-
// 3
Array
(
[0] => Array
(
[name] => Paul
)
)
Array
(
[0] => Array
(
[name] => Jenna
)
)
Desired Outcome
I would like to have everything merged into one array. The key is the index and the value is the name.
Array
(
[0] => Paul
[1] => Jenna
)

Answer 1

Loop through the array of objects ($arr) and compile the final array ($finArr) with the $val->string value. Try this:
$finArr = array();
foreach ($arr as $key => $val) {
$finArr[] = $val->string;
}

Answer 2

You can simply iterate through the array of readers, pull out the name of each reader, and add each of their names to a numerically indexed array as you desire.
$names = array(); // Initialize.
foreach($readers as $reader) {
if (!empty($reader->name)) {
$names[] = $reader->name;
}
}
print_r($names); // To see what you've got.
Array
(
[0] => Paul
[1] => Jenna
)

You have to extract key also from array. And declare $arr = array() outside foreach
$arr = array();
for ($i=0; $i < count($readers) ; $i++) {
$data = $readers[$i]->name; //change this line
array_push($arr, $data); // 3
}
print_r($arr);
Another way is you can simply use array_column()
$arr = array_column($readers,"name");
print_r($arr);
