Insert values in database after json_encode() - php

Question

I have two dimensional array, and I got needed result.
Now I need to insert it into db.
If the situation is [[]], that is one row in db and has specific number in db (it should start with 1).
If the situation is [[] , []], in that case values in brackets are dimension, each bracket is row, but they have the same name, for ex 2.
If there are more brackets inside [[] , [], [], []], in this case we will have 4 rows with the same name.
My database looks like
ID | DIMENSIONS | NAME
ID - auto increment
DIMENSIONS I take from below.
For ex.
[[12500,10]] - is one row, and for NAME it will have number 1.
[[12500,8],[6400,2]] - this is six element in array below. It will have two rows in database, and will have NAME 6.
echo json_encode($pak); // produces output below
"[[[12500,10]],[[12500,10]],[[12500,10]],[[12500,10]],[[12500,10]],[[12500,8],[6400,2]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[5558,10]],[[5558,10]],[[5558,8],[4600,2]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,6],[4500,4]],[[4500,10]],[[4500,10]],[[4500,10]],[[4500,10]],[[4500,8]]]"
I got stuck here, any help is appreciated.

Answer 1

We can achieve it by Recursion.
But here I didn't use recursion (Because I am not good at that)
I haven't tested properly, so please go through it carefully. let me know if it has any problem.
$data = "[[[12500,1]],[[12500,2]],[[12500,3]],[[12500,4]],[[12500,5]],[[111111,6],[22222,6]],[[6400,7]],[[6400,8]],[[6400,9]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[6400,10]],[[5558,10]],[[5558,10]],[[5558,8],[4600,2]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,10]],[[4600,6],[4500,4]],[[4500,10]],[[4500,10]],[[4500,10]],[[4500,10]],[[4500,8]]]";
$decoded = json_decode($data);
$namedArray = fix_name($decoded);
$insertArray = arrange_array($namedArray);
echo "<pre>";
print_r($insertArray);
echo "</pre>";die;
// Fix the Name first
function fix_name($decoded)
{
$number = 1;
foreach ($decoded as $key=> $value) {
$value['name'] = $number;
$insertArray[] = $value;
$number++;
}
return $insertArray;
}
function arrange_array($namedArray)
{
$insertArray = [];
foreach ($namedArray as $array) {
if (count($array) > 2) {
$name = $array['name'];
unset($array['name']);
foreach ($array as $key => $value) {
$array[$key]['name'] = $name;
}
foreach ($array as $arr) {
$insertArray[] = arrange($arr);
}
} else {
$temp['DIMENSIONS '] = $array[0];
$temp['NAME'] = $array['name'];
$insertArray[] = $temp;
}
}
return $insertArray;
}
function arrange($array)
{
$temp = [];
$temp['DIMENSIONS'] = [$array[0], $array[1]];
$temp['NAME'] = $array['name'];
return $temp;
}
Process:
First: Fix the names
Next: If count > 2 (because "name" key was added in previous function so will have minimum two )
then array in different way
else
key 0 as DIMENSIONS and key name as NAME
NOTE: There are other ways to achieve it but for quick fix I gave this.
