Laravel Lumen | get single values from array - php

Question

I have a problem for like 4 hours.
$getrank = DB::table('users')->select('codes')->orderBy('codes', 'desc')->get();
with var_dump($getrank); I see whats in the array.
So I got this:
array(6) {
[0] => object(stdClass)#62 (1) {
["codes"]=> int(584)
}
[1] => object(stdClass)#64 (1) {
["codes"]=> int(117)
} [2] => object(stdClass)#65 (1) {
["codes"]=> int(88)
} [3] => object(stdClass)#66 (1) {
["codes"]=> int(66)
} [4] => object(stdClass)#67 (1) {
["codes"]=> int(53)
} [5] => object(stdClass)#68 (1) {
["codes"]=> int(37)
}
}
But I want them seperated.
I tried a lot!
In the end I thought this could be my answer:
echo $getrank[0]['codes'];
echo $getrank[1]['codes'];
echo $getrank[2]['codes'];
echo $getrank[3]['codes'];
echo $getrank[4]['codes'];
echo $getrank[5]['codes'];
But no.
I want a ranking, and I just need the first 5 ([0]-[4]). What else can I do?
In the end I want every value as a string!

Answer 1

Ok, now by reading your comments I understand what is the result you expect.
$getrank = array_map(
function ($user) { return $user->codes; },
DB::table('users')->orderBy('codes', 'desc')->take(5)->get()
);
Does that get you what you want?

Answer 2

Just use the pluck() (or lists(), alias of pluck()) method for this.
$codes = DB::table('users')->orderBy('codes', 'desc')->take(5)->lists('codes');
echo '<pre>';
foreach($codes as $key => $code) {
echo 'code '.$key.': '.$code.PHP_EOL;
}
echo '</pre>';

You can try to add toArray(), this will convert result from database to array, so you can use the code you've provided at the end of your question
$getrank = DB::table('users')->select('codes')->orderBy('codes', 'desc')->get()->toArray();
foreach($getrank as $rank) {
echo $rank['codes'];
}
And if you want to cast codes value to string, it is just echo (string) $rank['codes'];
