I'm trying to parse a string which looks like this :
"['x','y','z',['a'],[],[['name','2'],['name','40']]]"
I would like to put everythings in an array like this :
0 => string 'x' (length=1)
1 => string 'y' (length=1)
2 => string 'z' (length=1)
3 =>
array (size=1)
0 => string 'a' (length=1)
4 =>
array (size=0)
empty
5 =>
array (size=2)
0 =>
array (size=2)
0 => string 'name' (length=4)
1 => string '2' (length=1)
1 =>
array (size=2)
0 => string 'name' (length=4)
1 => string '40' (length=2)
Is there a proper way to do it because I tried to make a bunch of functions, but at the end it's always a mess and it doesn't work.
Thats nearly a JSON String, so make it into one and from there its easy running
$nearlyJson = "['x','y','z',['a'],[],[['name','2'],['name','40']]]";
$nowItsJson = str_replace("'", '"', $nearlyJson );
$NowItsAPHPArray = json_decode($nowItsJson );
print_r($NowItsAPHPArray );
RESULT
Array
(
[0] => x
[1] => y
[2] => z
[3] => Array
(
[0] => a
)
[4] => Array
(
)
[5] => Array
(
[0] => Array
(
[0] => name
[1] => 2
)
[1] => Array
(
[0] => name
[1] => 40
)
)
)

Does anyone know how to correctly sort this array by version preserving the sub-arrays.
I have seen similar issues and solutions on stackoverflow but im not able to apply to my array.
Thanks in advance
array (size=3)
'1.23.006' =>
array (size=1)
0 => string '1' (length=1)
'2.0.0' =>
array (size=1)
0 => string '1' (length=1)
'10.0.0' =>
array (size=2)
0 => string '1' (length=1)
1 => string '4' (length=1)
I want it to be sorted like this:
array (size=3)
'10.0.0' =>
array (size=2)
0 => string '1' (length=1)
1 => string '4' (length=1)
'2.0.0' =>
array (size=1)
0 => string '1' (length=1)
'1.23.006' =>
array (size=1)
0 => string '1' (length=1)
You need to use uksort to sort your array by keys, with a custom function that calls version_compare to compare them:
$data = array('1.23.006' => array('1'), '2.0.0' => array('1'), '10.0.0' => array('1', '4'));
uksort($data, function ($a, $b) {
return version_compare($b, $a);
});
print_r($data);
Output:
Array
(
[10.0.0] => Array
(
[0] => 1
[1] => 4
)
[2.0.0] => Array
(
[0] => 1
)
[1.23.006] => Array
(
[0] => 1
)
)

How to Sort a Multi-dimensional Array by Value
(16 answers)
Closed 10 months ago.
I have this array:
I want to order it from bigger to smaller sorted by the number in the second column.
I can't get to the second one :(
array (size=72)
0 =>
array (size=2)
0 => string 'Australian SPI 200' (length=18)
1 => string '-0.055' (length=6)
1 =>
array (size=2)
0 => string 'CAC 40' (length=6)
1 => string '-0.007' (length=6)
2 =>
array (size=2)
0 => string 'DAX' (length=3)
1 => string '0.007' (length=5)
3 =>
array (size=2)
0 => string 'EuroStoxx50' (length=11)
1 => string '0.000' (length=5)
function sortByOrder($a, $b) {
return $a['1'] - $b['1'];
}
$myArray=array (array ( 'Australian SPI 200' , -0.040 ) , array ( 'CAC 40', -0.006 ) ,array ( 'DAX' ,0.009 ));
usort($myArray, 'sortByOrder');
print_r($myArray);
output
Array ( [0] => Array ( [0] => DAX [1] => 0.009 ) [1] => Array ( [0] => CAC 40 [1] => -0.006 ) [2] => Array ( [0] => Australian SPI 200 [1] => -0.04 ) )
I have an array like this
Array
(
[name] => Array
(
[0] => img/test240.jpg
[1] => img/cs1.jpg
[2] => img/cs2.jpg
[3] => img/cs3.jpg
)
[link] => Array
(
[0] => http://google.com
[1] => http://google.com
[2] => http://facebook.com
[3] => http://orkut.com
)
[order] => Array
(
[0] => 4
[1] => 1
[2] => 2
[3] => 3
)
)
I need to sort it by order WHICH IS KEY in Multidimensional array. Here is output.
Array
(
[name] => Array
(
[1] => img/cs1.jpg
[2] => img/cs2.jpg
[3] => img/cs3.jpg
[0] => img/test240.jpg
)
[link] => Array
(
[1] => http://google.com
[2] => http://facebook.com
[3] => http://orkut.com
[0] => http://google.com
)
[order] => Array
(
[1] => 1
[2] => 2
[3] => 3
[0] => 4
)
)
In this you can see when order is sorted name and link is also sorted according to the order. How can i do this with php.
You have to use array_map() in conjunction with sort().
If you want to preserve actual element order you have to use asort() instead sort().
Try this code:
$arr = array(
'name' => array(
0 => 'img/test240.jpg',
1 => 'img/cs1.jpg',
2 => 'img/cs2.jpg',
3 => 'img/cs3.jpg',
),
'link' => array(
0 => 'http://google.com',
1 => 'http://google.com',
2 => 'http://facebook.com',
3 => 'http://orkut.com',
),
'order' => array(
0 => 4,
1 => 1,
2 => 2,
3 => 3,
),
);
function mysort($a) {
asort($a);
return $a;
}
$arr = array_map('mysort', $arr);
print_r($arr);
Demo.
Try this, it uses array_multisort:
$array holds:
array (size=3)
'name' =>
array (size=4)
0 => string 'img/test240.jpg' (length=15)
1 => string 'img/cs1.jpg' (length=11)
2 => string 'img/cs2.jpg' (length=11)
3 => string 'img/cs3.jpg' (length=11)
'link' =>
array (size=4)
0 => string 'http://google.com' (length=17)
1 => string 'http://google.com' (length=17)
2 => string 'http://facebook.com' (length=19)
3 => string 'http://orkut.com' (length=16)
'order' =>
array (size=4)
0 => string '4' (length=1)
1 => string '1' (length=1)
2 => string '2' (length=1)
3 => string '3' (length=1)
Code:
$sort = array();
foreach($array as $k) {
foreach($k as $ind=>$val){
$sort['name'][$ind] = $array['name'][$ind];
$sort['link'][$ind] = $array['link'][$ind];
$sort['order'][$ind] = $array['order'][$ind];
}
}
array_multisort($sort['order'], SORT_ASC, $sort['link'], SORT_ASC, $sort['name'], SORT_ASC);
var_dump($sort);
Output:
array (size=3)
'name' =>
array (size=4)
0 => string 'img/cs1.jpg' (length=11)
1 => string 'img/cs2.jpg' (length=11)
2 => string 'img/cs3.jpg' (length=11)
3 => string 'img/test240.jpg' (length=15)
'link' =>
array (size=4)
0 => string 'http://google.com' (length=17)
1 => string 'http://facebook.com' (length=19)
2 => string 'http://orkut.com' (length=16)
3 => string 'http://google.com' (length=17)
'order' =>
array (size=4)
0 => string '1' (length=1)
1 => string '2' (length=1)
2 => string '3' (length=1)
3 => string '4' (length=1)
$this_arr = array(1,2,3,0);
function my_sort_2($arr, $arrangement)
{
$flag = false;
foreach($arr as $key => $val)
{
if(is_array($arr[$key]))
{
$arr[$key] = my_sort_2($arr[$key],$arrangement);
$flag = true;
}
}
if($flag == false && is_array($arr) && is_assoc($arr) === false)
{
$temp = array();
for($i = 0; $i < count($arrangement); $i++)
{
if(isset($arr[$arrangement[$i]]))
{
$temp[$arrangement[$i]] = $arr[$arrangement[$i]];
unset($arr[$arrangement[$i]]);
}
}
//$arr = array_merge($temp,$arr);
$arr = $temp;
}
return $arr;
}
Include this function below to run my own function. Also credit to #Matt Whittingham where i got this code from
function is_assoc($array)
{
$keys = array_keys($array);
return array_keys($keys) !== $keys;
}
Now let's do some sortin'... print_r(my_sort_2($arr,$this_arr)); assuming $arr contains Shan's array.
The output is EXACTLY what you desired.
It'll search for nested array (at least intended) and see if it's in a standard numeric ordered keys (in short, not custom order - yet; and not assoc) then sort it the way you want.
Note: I know my code isn't that probably good, optimized or bug free and that's my second attempt, misunderstanding your requirements first time (see the function name?).
Well after some research i found a simple solution like this
asort($data['order']);
$keys = array_keys($data['order']);
$data['name'] = array_replace(array_flip($keys), $data['name']);
$data['link'] = array_replace(array_flip($keys), $data['link']);
$data['order'] = array_replace(array_flip($keys), $data['order']);
Although i dont want to apply array_replace and array_flip on all the keys but this is done for the time being. I will surely trying to find how i can do it with single instruction.
i have two arrays and i need to extract the values of the 2nd array depending on the value of $arr[0]["num"]
$arr = array(
0 => array(
"id" => 24,
"num" => 2
),
1 => array(
"id" => 25,
"num" => 5
)
2 => array(
"id" => 26,
"num" => 3
)
);
$array = array('1','2','3','4','5','6','7','8','9','10');
$new = array();
foreach($arr as $key){
for($i=0;$i<$key['num'];$i++){
$new[$key['id']][$i] = $array[$i];
}
}
is it possible to remove the values of the 2nd array and transfer it into a new array?
what my loop does is just copying the values from the start after each loop. i want to remove the copied values from the 2nd array.
The output should be like this:
Array
(
[24] => Array
(
[0] => 1
[1] => 2
)
[25] => Array
(
[0] => 3
[1] => 4
[2] => 5
[3] => 6
[4] => 7
)
[26] => Array
(
[0] => 8
[1] => 9
[2] => 10
)
)
I'd suggest using array_shift
$arr = array(
array(
"id" => 24,
"num" => 2
),
array(
"id" => 25,
"num" => 5
),
array(
"id" => 26,
"num" => 3
)
);
$array = array('1','2','3','4','5','6','7','8','9','10');
$new = array();
foreach($arr as $key){
for($i=0;$i<$key['num'];$i++){
$new[$key['id']][$i] = $array[0]; // *1
array_shift($array);
}
}
echo '<pre>';
print_r($new);
*1 You have to change this line as well. Since array_shift removes the first array entry, each iteration should access array[0].
Output:
Array
(
[24] => Array
(
[0] => 1
[1] => 2
)
[25] => Array
(
[0] => 3
[1] => 4
[2] => 5
[3] => 6
[4] => 7
)
[26] => Array
(
[0] => 8
[1] => 9
[2] => 10
)
)
Try this
foreach($arr as $key){
for($i=0;$i<$key['num'];$i++){
$new[$key['id']][$i] = $array[$i];
// unset previous values, in first iteration it will remove 0, 1
unset($array[$i]);
}
// reset the array keys, so for loop $i will start from 0
$array = array_values($array);
}
Output:
array (size=3)
24 =>
array (size=2)
0 => string '1' (length=1)
1 => string '2' (length=1)
25 =>
array (size=5)
0 => string '3' (length=1)
1 => string '4' (length=1)
2 => string '5' (length=1)
3 => string '6' (length=1)
4 => string '7' (length=1)
26 =>
array (size=3)
0 => string '8' (length=1)
1 => string '9' (length=1)
2 => string '10' (length=2)
I have here a nested multidimensional array:
Array
(
[merchant] => Array
(
[XML_Serializer_Tag] => Array
(
[id] => 736
[name] => Cadbury Gifts Direct
)
[prod] => Array
(
[XML_Serializer_Tag] => Array
(
[0] => Array
(
[XML_Serializer_Tag] => Array
(
[id] => 88966064
[pre_order] => no
[web_offer] => no
[in_stock] => no
[stock_quantity] => 0
)
[pId] => 608
[isbn] => 0000000000000
[text] => Array
(
[name] => 50% OFF 56g Creme Egg Minis
[desc] => 50% OFF Creme Egg Minis in a 56g bag.
)
[uri] => Array
(
[awTrack] => http://www.awin1.com/pclick.php?p=88966064&a=67702&m=736
[awThumb] => http://images.productserve.com/thumb/736/88966064.jpg
[awImage] => http://images.productserve.com/preview/736/88966064.jpg

[mImage] => http://www.cadburygiftsdirect.co.uk/images/thumbs/0001084.png
)
[price] => Array
(
[XML_Serializer_Tag] => Array
(
[curr] => GBP
)
[buynow] => 0.31
[store] => 0.00
[rrp] => 0.00
[delivery] => 0.00
)
[cat] => Array
(
[awCatId] => 437
[awCat] => Chocolate
[mCat] => Full Range
)
[brand] =>
[valFrom] => 0000-00-00
[valTo] => 0000-00-00
[comAmount] => 0.00
)
The segment loop afterwards.
So...
[1] => Array
[2] => Array
[3] => Array
etc...
I need to find the names of the attributes of each array segment.
So I have used this recursive loop:
private function recursive_array($old_array, $new_array = array()) {
foreach ($old_array as $key => $value) {
if (is_array($value) && $key < 1) {
$new_array = $this->recursive_array($value, $new_array);
} else {
if ($key < 1) {
$new_array[] = $key;
}
}
}
return $new_array;
}
This is the output:
array
0 => string 'id' (length=2)
1 => string 'name' (length=4)
2 => string 'id' (length=2)
3 => string 'pre_order' (length=9)
4 => string 'web_offer' (length=9)
5 => string 'in_stock' (length=8)
6 => string 'stock_quantity' (length=14)
7 => string 'pId' (length=3)
8 => string 'isbn' (length=4)
9 => string 'name' (length=4)
10 => string 'desc' (length=4)
11 => string 'awTrack' (length=7)
12 => string 'awThumb' (length=7)
13 => string 'awImage' (length=7)
14 => string 'mLink' (length=5)
15 => string 'mImage' (length=6)
16 => string 'curr' (length=4)
17 => string 'buynow' (length=6)
18 => string 'store' (length=5)
19 => string 'rrp' (length=3)
20 => string 'delivery' (length=8)
21 => string 'awCatId' (length=7)
22 => string 'awCat' (length=5)
23 => string 'mCat' (length=4)
24 => string 'brand' (length=5)
25 => string 'valFrom' (length=7)
26 => string 'valTo' (length=5)
27 => string 'comAmount' (length=9
What it is also picking up is the top nested array:
[XML_Serializer_Tag] => Array
(
[id] => 736
[name] => Cadbury Gifts Direct
)
This is just details for the entire feed not the individual segments.
I need a way of filtering out the top nested array but bear in mind that the details are dynamic so the name of the keys can change from one feed to the next
Maybe this?
$riter = new RecursiveIteratorIterator(New RecursiveArrayIterator($array));
foreach ($riter as $key => $val) {
if ($riter->getDepth() > 1) {
echo "$key => $val\n";
}
}
by default, RecursiveIteratorIterator only visits leaf nodes(the deepest levels down every path). getDepth() can be used to make sure were a minimum depth. I'm not sure if 1 is the correct number, but anyway...
use array_shift to pop off the first element of the array
