Array data manipulations PHP - php

Question

I get from my DB data in format like this:
array(12) {
[0]=>
array(4) {
["id"]=>
string(1) "1"
["count"]=>
string(5) "78984"
["month"]=>
string(1) "6"
["hours"]=>
string(10) "10580.0833"
}
[1]=>
array(4) {
["id"]=>
string(1) "2"
["count"]=>
string(5) "64174"
["month"]=>
string(1) "6"
["hours"]=>
string(9) "6866.8333"
}
[2]=>
array(4) {
["id"]=>
string(1) "3"
["count"]=>
string(5) "31032"
["month"]=>
string(1) "6"
["hours"]=>
string(9) "3700.9167"
}
[3]=>
array(4) {
["id"]=>
string(1) "1"
["count"]=>
string(5) "91114"
["month"]=>
string(1) "7"
["hours"]=>
string(10) "11859.6000"
}
...
Each of array inside has a key: "id". It mostly look values from 1 to 3. I would like to create a new array based on this "ids" that would look like this:
array("number of unique ids") {
[0]=> "for id = 0"
array(12) {
int() count/hours
int() count/hours
int() count/hours
...
}
[1]=> "for id = 1 and so on..."
array(12){
....
}
I`ve been trying to do it like this:
$data1 = [];
$data2 = [];
$data3 = [];
foreach($data as $key => $record){
if($record['id'] == 1){
array_push($data1, $record['count']/$record['hours']);
}else if($data['id_zmiana'] == 2){
array_push($data2, $record['count']/$record['hours']);
}else{
array_push($data3, $record['count']/$record['hours']);
}
}
$raport = array_merge($data1, $data2, $data3);
And that would work, but it doesn`t look good in my opinion, beacuse what if the id change to some big number.

Answer 1

Yeah, having separate arrays for each ID is not a good idea. How about:
$raport = [];
foreach ($data as $record) {
$raport[$record['id']][] = $record['count'] / $record['hours']);
}
Simple, and straight to the point.
Haven't tested it. Next time try to use var_export() to export the data you put in your question. That way we can actually use it, without having to rewrite it completely.
