How can i arrange array before specific array key in PHP - php

Question

I would like to arrange Array before found a specific array key. For example
Following is array.
Array(
[0] => Array([package_name] => 10.4)
[1] => Array([final_total] => 10.4)
[2] => Array([package_name] => 10.5)
[3] => Array([package_name] => 4.5)
[4] => Array([final_total] => 15)
[5] => Array([package_name] => 15.2)
[6] => Array([final_total] => 15.2)
[7] => Array([package_name] => 8.4)
[8] => 8.4
)
And I want like array.
(
[0] => Array
(
[package_name] => array([0]=>10.4),
[final_total] => 10.4
)
[1] => Array
(
[package_name] => array(
[0] => 10.5,
[1] => 4.5
),
[final_total] => 15
)
[2] => Array
(
[package_name] => array([0]=>15.2)
[final_total] => 15.2
)
[3] => Array
(
[package_name] => array([0]=>8.4)
[final_total] => 8.4
)
)
So What i want If final_total key is found from array then set previous values(package_name) of final_total in a array.
Above example you can see there are 4 final_total key's of array so i want to set each package_name's value in a array that are previous value of final_total.
Following is my code.
This is my array
$main = array(array('package_name' => 10.4),array('final_total' => 10.4),array('package_name' => 10.5),array('package_name' => 4.5),array('final_total' => 15)
,array('package_name' => 15.2),array('final_total' => 15.2));
Code.
<?php
$newArray = [];
$newPackag=[];
$previousValue='';
$currentKey=0;
$PreviousKey=0;
$i=0;
$main_keys = array_keys($main);
foreach ($main as $key => $value) {
$curtent_item[] = isset($main[$key]['package_name']) ? $main[$key]['package_name'] : '';
$currentKey = $key;
if(#$main[$key]['final_total'] ==#$value['final_total']){
$previousValue = #$value['package_name'];
$newArray[] = $previousValue;
$myarray= array(#$main[$key]['package_name']);
if (array_key_exists("final_total",$main[$key])){
if($PreviousKey ==0){
$PreviousKey = $key+1;
}else{
$PreviousKey = $key;
}
}else{
$keys = array_keys($main);
$position = array_search($key, $keys);
echo "Curent Key =".$currentKey.'PreviousKey'.$PreviousKey.'</br>';
if($currentKey != $PreviousKey){
$nextKey = $keys[$currentKey+1 ];
}
$newPackag1[] = array('package_name'=>#$myarray);
}
$mainArray = array('package'=>$newPackag1);
}
$i++;
}
echo "<pre>NE page";print_r($newPackag1);
echo "<pre>";print_r($main);
anyone has better and correct solution. Above code which i am trying not able to get desire output.

Here is the snippet with modified data(surely will work for your case too),
$result = [];$i= 0;
foreach ($main as $key => $value) {
if (is_array($value)) {
$k = key($value);$v = array_shift($value);
($k != 'final_total' ? $result[$i][$k][] = $v : $result[$i][$k] = $v);
if($k == 'final_total'){
$i++;
}
} elseif (!empty($value)) {
$result[$i]['final_total'] = $value;
}
}
print_r($result);
Demo
Output:-
Array
(
[0] => Array
(
[package_name] => Array
(
[0] => 6.5
[1] => 9
)
[final_total] => 15.5
)
[1] => Array
(
[package_name] => Array
(
[0] => 10.5
)
[final_total] => 10.5
)
[2] => Array
(
[package_name] => Array
(
[0] => 17.1
)
[final_total] => 17.1
)
[3] => Array
(
[package_name] => Array
(
[0] => 9.8
)
[final_total] => 9.8
)
[4] => Array
(
[package_name] => Array
(
[0] => 16
)
[final_total] => 16
)
[5] => Array
(
[package_name] => Array
(
[0] => 10.5
)
[final_total] => 10.5
)
)
