Create new array depending on key - php

Question

My array is like that:
Array
(
[0] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 1
[tran_name] => private
[tran_image] => 1251961905A1.jpg
[type] => car
[troute_id] => 10
)
[1] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 2
[tran_name] => express
[tran_image] => bus3.jpg
[type] => car
[troute_id] => 13
)
[2] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 3
[tran_name] => MyanmarTrain
[tran_image] => Burma-Gorteikviaduct.jpg
[type] => train
[troute_id] => 16
)
[3] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 4
[tran_name] => Ayeyarwaddy Cruise
[tran_image] => boat-ChutzpahToo1.jpg
[type] => cruise
[troute_id] => 22
)
)
I want to change that array like that depending on key['type']. If array key['type'] are same, I want to change array like that:
Array
(
[car] => Array(
[0]=>Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 1
[tran_name] => private
[tran_image] => 1251961905A1.jpg
[type] => car
[troute_id] => 10
),
[1] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 2
[tran_name] => express
[tran_image] => bus3.jpg
[type] => car
[troute_id] => 13
)
),
[train]=>Array(
[0] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 3
[tran_name] => MyanmarTrain
[tran_image] => Burma-Gorteikviaduct.jpg
[type] => train
[troute_id] => 16
)
[cruise]=>Array(
[0] => Array
(
[des_id] => 1
[des_name] => bagan
[tran_id] => 4
[tran_name] => Ayeyarwaddy Cruise
[tran_image] => boat-ChutzpahToo1.jpg
[type] => cruise
[troute_id] => 22
)
)
)
)
what I mean is that if key['type'] is car, I want to create car array or if the type is train I want to create train array or if the type is cruise I want to create cruise array. I don't know how to loop the array. Anyone please help me. Thanks a lot!

Answer 1

Here's a simple way to do it: loop over the data, and just append to the subarray matching the type value:
// starting data
$starting_array = array (
0 => array (
'des_id' => 1,
'des_name' => 'bagan',
'tran_id' => 1,
'tran_name' => 'private',
'tran_image' => '1251961905A1.jpg',
'type' => 'car',
'troute_id' => 10
),
1 => array (
'des_id' => 1,
'des_name' => 'bagan',
'tran_id' => 2,
'tran_name' => 'express',
'tran_image' => 'bus3.jpg',
'type' => 'car',
'troute_id' => 13
),
2 => array (
'des_id' => 1,
'des_name' => 'bagan',
'tran_id' => 3,
'tran_name' => 'MyanmarTrain',
'tran_image' => 'Burma-Gorteikviaduct.jpg',
'type' => 'train',
'troute_id' => 16
),
3 => array (
'des_id' => 1,
'des_name' => 'bagan',
'tran_id' => 4,
'tran_name' => 'Ayeyarwaddy Cruise',
'tran_image' => 'boat-ChutzpahToo1.jpg',
'type' => 'cruise',
'troute_id' => 22
)
);
// initialize the result array
$result = array();
// loop over the starting array
foreach($starting_array as $entry) {
// make sure the result array has a key matching this item's type
if(!array_key_exists($entry['type'], $result)) {
$result[ $entry['type'] ] = array();
}
// add this item to the result array
$result[ $entry['type'] ][] = $entry;
}
// this is just for testing, so you can verify the output matches your desired result
echo "<pre>";
var_dump($result);
echo "</pre>";

Try this:
<?php
$tempArr = Array
(
Array(
"des_id" => 1,
"des_name" => "bagan",
"tran_id" => 1,
"tran_name" => "private",
"tran_image" => "1251961905A1.jpg",
"type" => "car",
"troute_id" => 10
),
Array
(
"des_id" => 1,
"des_name" => "bagan",
"tran_id" => 2,
"tran_name" => "express",
"tran_image" => "bus3.jpg",
"type" => "car",
"troute_id" => 13
),
Array
(
"des_id" => 1,
"des_name" => "bagan",
"tran_id" => 3,
"tran_name" => "MyanmarTrain",
"tran_image" => "Burma-Gorteikviaduct.jpg",
"type" => "train",
"troute_id" => 16
),
Array
(
"des_id" => 1,
"des_name" => "bagan",
"tran_id" => 4,
"tran_name" => "Ayeyarwaddy Cruise",
"tran_image" => "boat-ChutzpahToo1.jpg",
"type" => "cruise",
"troute_id" => 22
)
);
$resultArr = array();
foreach($tempArr as $tempKey=>$temp)
{
if(!array_key_exists($temp['type'], $resultArr))
{
$resultArr[$temp['type']] = array();
}
$resultArr[$temp['type']][] = $temp;
}
echo '<pre>';
print_r($resultArr);
?>
This is working fine .....
