How to extract and access data from JSON with PHP?
(1 answer)
Closed 2 years ago.
Actual JSON Object
[[["पिता का नाम","Father's name",null,null,1] ,[null,null,"pita ka naam"] ] ,null,"en",null,null,[["Father's name",null,[["पिता का नाम",1000,true,false] ] ,[[0,13] ] ,"Father's name",0,0] ] ,1.0,[] ,[["en"] ,null,[1.0] ,["en"] ] ]
After doing json_decode; i am getting below result.
i want to access first value which is in Hindi(INDIAN LANGUAGE)
Array ( [0] => Array ( [0] => Array ( [0] => पिता का नाम [1] => Father's name [2] => [3] => [4] => 1 ) [1] => Array ( [0] => [1] => [2] => pita ka naam ) ) [1] => [2] => en [3] => [4] => [5] => Array ( [0] => Array ( [0] => Father's name [1] => [2] => Array ( [0] => Array ( [0] => पिता का नाम [1] => 1000 [2] => 1 [3] => ) ) [3] => Array ( [0] => Array ( [0] => 0 [1] => 13 ) ) [4] => Father's name [5] => 0 [6] => 0 ) ) [6] => 1 [7] => Array ( ) [8] => Array ( [0] => Array ( [0] => en ) [1] => [2] => Array ( [0] => 1 ) [3] => Array ( [0] => en ) ) )
You can access properties of an array by index. The index starts at 0 being the first position then 1, and so on.
$arr = ['a','b','c'];
echo $arr[0]; //Output is 'a'
echo $arr[1]; //Output is 'b'
If you have a multi-dimensional array you just access the first property of the first array and then the second property of the second array like so:
$arr = [
['a','b','c'],
['d','e','f']
];
echo $arr[0][2]; //Output is 'c'
Note: in this example, $arr[0] is the first array holding a,b & c.
In your exact example, it looks like there are 4 nested arrays, so to get the Hindi text it would be:
echo $arr[0][0][0][0];

How to Flatten a Multidimensional Array?
(31 answers)
Closed 7 months ago.
There are many references on S/O showing various methods to flatten a multidimensional recursive array (with more than two levels). I have been through dozens (and tried most) but I'm still running into an odd problem with every one I've tried. What I am getting as a result is:
Array
(
)
Array

Array
(

Array
(
[0] => 1000043
[1] => 1000045
[2] => 1000050

(
[0] => 1000030
[1] => 1000032
[2] => 1000058
[3] => 1000064
) ...
But what I'm expecting is a truly flattened single array:
Array
[0] => 1000043
[1] => 1000045
[2] => 1000050
[3] => 1000030
[4] => 1000032
[5] => 1000058
[6] => 1000064
)
The method I found on S/O is supposed to handle an "empty array" (which I assume is the problem) but I'm still getting the wrong output. Here is my code:
function array_flatten5(array $array)
{
$flat = array(); // initialize return array
$stack = array_values($array); // initialize stack
while($stack) // process stack until done
{
$value = array_shift($stack);
if (is_array($value)) // a value to further process
{
$stack = array_merge(array_values($value), $stack);
}
else // a value to take
{
$flat[] = $value;
}
}
return $flat;
}
Could someone point out what I missing here because I'm thinking it's something simple but at this point my eyes are crossed with the number of attempts I've made. Thank you for any help you can provide.
Here is the original array. It is 4-deep:
Array ( [0] => 1000043 [1] => 1000045 [2] => 1000050 ) Array ( [0] => 1000030 [1] => 1000032 [2] => 1000058 [3] => 1000064 ) Array ( [0] => 1000041 [1] => 1000059 [2] => 1000069 ) Array ( [0] => 1000021 [1] => 1000044 [2] => 1000049 [3] => 1000071 ) Array ( [0] => 1000009 [1] => 1000013 [2] => 1000015 [3] => 1000017 [4] => 1000053 ) Array ( [0] => 1000022 [1] => 1000034 [2] => 1000070 ) Array ( [0] => 1000038 [1] => 1000047 [2] => 1000055 [3] => 1000063 ) Array ( [0] => 1000019 [1] => 1000054 [2] => 1000060 [3] => 1000066 [4] => 1000068 ) Array ( [0] => 1000006 [1] => 1000014 [2] => 1000016 [3] => 1000072 ) Array ( [0] => 1000024 [1] => 1000025 [2] => 1000046 [3] => 1000061 [4] => 1000067 ) Array ( [0] => 1000028 [1] => 1000039 [2] => 1000048 ) Array ( [0] => 1000042 [1] => 1000057 ) Array ( [0] => 1000027 [1] => 1000033 [2] => 1000036 [3] => 1000037 ) Array ( [0] => 1000008 [1] => 1000010 [2] => 1000012 [3] => 1000018 ) Array ( [0] => 1000026 [1] => 1000062 [2] => 1000065 ) Array ( [0] => 1000020 [1] => 1000023 [2] => 1000031 [3] => 1000035 [4] => 1000040 ) Array ( [0] => 1000007 [1] => 1000011 [2] => 1000029 ) Array ( [0] => 1000051 [1] => 1000052 [2] => 1000056 ) Array ( [0] => 1000001 [1] => 1000002 [2] => 1000003 [3] => 1000004 [4] => 1000005 ) Array ( [0] => 1000073 )

You didn't prepare suitable array, but looking on this code you need probably just array_walk_recursive() function.
$array = [
[1, 2, 3, 4],
[[5, 6], [7, 8]],
[[[9], [10]], [11]]
];
$result = [];
array_walk_recursive($array, function ($tempV) use (&$result) {
$result[] = $tempV;
});
print_r($result);
Output:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
[9] => 10
[10] => 11
)
I have 2 PHP arrays that look like this..
$array1
--------
Array
(
[0] => Array
(
[0] => 64
[1] => Apple
)
[1] => Array
(
[0] => 22
[1] => Pear
)
[2] => Array
(
[0] => 3
[1] => Raisin
)
[3] => Array
(
[0] => 15
[1] => Grape
)
[4] => Array
(
[0] => 11
[1] => Banana
)
[5] => Array
(
[0] => 4
[1] => Orange
)
)
$array2
--------
Array
(
[0] => Array
(
[0] => 22
[1] => Pear
)
[1] => Array
(
[0] => 11
[1] => Banana
)
)
I want to merge the arrays together but put the matching items from $array2 at the top so the result would look like this...
$array3
-------
Array
(
[0] => Array
(
[0] => 22
[1] => Pear
)
[1] => Array
(
[0] => 11
[1] => Banana
)
[2] => Array
(
[0] => 64
[1] => Apple
)
[3] => Array
(
[0] => 3
[1] => Raisin
)
[4] => Array
(
[0] => 15
[1] => Grape
)
[5] => Array
(
[0] => 4
[1] => Orange
)
)
I'm not sure how to approach, should I merge the two first and then try and do some ordering, or is there a more efficient approach?
Get the 2nd array and then a rest of the 1st array
array_merge($arr2, array_udiff($arr1, $arr2, function($i1, $i2) {return $i1[0]-$i2[0];}));
Hi I am working on some array operations.
I need to convert first value of array as key and second value of array as value.
I have one variable $testArray which stores array like below.
Array
(
[0] => Array
(
[0] => Color
[1] => White on Red
)
[1] => Array
(
[0] => Depicted Text
[1] => EMPTY
)
[2] => Array
(
[0] => Depth [Nom]
[1] => 0.004 in
)
[3] => Array
(
[0] => Language
[1] => English
)
[4] => Array
(
[0] => Length [Nom]
[1] => 10 in
)
[5] => Array
(
[0] => Material
[1] => Adhesive Vinyl
)
[6] => Array
(
[0] => Mounting
[1] => Surface
)
[7] => Array
(
[0] => Width [Nom]
[1] => 14 in
)
[8] => Array
(
[0] => Wt.
[1] => 0.056 lb
)
)
Expected output :
Array
(
[0] => Array
(
[Color] => White on Red
)
[1] => Array
(
[Depicted Text] => EMPTY
)
[2] => Array
(
[Depth [Nom]] => 0.004 in
)
[3] => Array
(
[Language] => English
)
[4] => Array
(
[Length [Nom]] => 10 in
)
[5] => Array
(
[Material] => Adhesive Vinyl
)
[6] => Array
(
[Mounting] => Surface
)
[7] => Array
(
[Width [Nom]] => 14 in
)
[8] => Array
(
[Wt.] => 0.056 lb
)
)
I have already tried with array function array_keys and array_values but it won't working
Simple solution using array_map function:
$result = array_map(function($v){
return [$v[0] => $v[1]];
}, $testArray);
Assuming that structure will always be the same, you could do this:
$output = array();
foreach($testArray as $v){
$output[] = array($v[0] => $v[1]);
}
See it in action here.
I need to merge a PHP array, this array has 2 arrays into it named "targetXX", I can have 2 or more. Each target have the same keys, for each key I have an array with 2 values a and b, a is always the same in both targets, but I need to merge both B values like this:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200
[1] => 1392282200
)
[1] => Array
(
[0] => 1400
[1] => 1392282260
)
[2] => Array
(
[0] => 600
[1] => 1392282320
)
[3] => Array
(
[0] => 200
[1] => 1392282380
)
[4] => Array
(
[0] => 400
[1] => 1392282440
)
[5] => Array
(
[0] => 600
[1] => 1392282500
)
)
)
[1] => Array
(
[target] => hitcount(stats.asdf.requests, "1min")
[datapoints] => Array

Use array_merge() to achieve this:
$newArray = array();
foreach ($myArray['target2'] as $key => $innerArr1) {
$newArray['target'][$key] = array_merge(
$myArray['target1'][$key], /* 0th and 1st index */
array($innerArr1[1]) /* 2nd index */
);
}
print_r($newArray);
Output:
Array
(
[target] => Array
(
[0] => Array
(
[0] => 333333
[1] => 13
[2] => 99
)
[1] => Array
(
[0] => 444444
[1] => 15
[2] => 98
)
[2] => Array
(
[0] => 555555
[1] => 17
[2] => 97
)
)
)

The built-in function array_merge may do the work for you. You need to merge each subarrays in fact, as the array_merge_recursive function doesn't handle indexes.
$newArray = array();
foreach ($myArray['target2'] as $key => $arr) {
$newArray['target'][$key] = array_merge($myArray['target1'][$key], $arr[1]);
}
Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
If you have more than 2 keys to merge, you can loop on the algorithm multiple times.
i have a multi dimension array with sub array having repeated values of 'eduHisRowId' like:
Array
(
[0] => Array
(
[eduHisRowId] => 4
[repOrderId] => 15
)
[1] => Array
(
[eduHisRowId] => 5
[repOrderId] => 16
)
[2] => Array
(
[eduHisRowId] => 5
[repOrderId] => 17
)
[3] => Array
(
[eduHisRowId] => 6
[repOrderId] => 18
)
[4] => Array
(
[eduHisRowId] => 7
[repOrderId] => 19
)
[5] => Array
(
[eduHisRowId] => 7
[repOrderId] => 20
)
[6] => Array
(
[eduHisRowId] => 8
[repOrderId] => 21
)
)
Now i want sort out these repeated values such that i could be able to check that the record present on index '[1] => Array' is associated with the record which is present on index '[2] => Array' & this associated relation will also be in array format like:
Array
(
[0] => Array
(
[0] => 4
[1] => Array
(
[0] => 15
)
)
[1] => Array
(
[0] => 15
[1] => Array
(
[0] => 16
[0] => 17
)
)
[2] => Array
(
[0] => 6
[1] => Array
(
[0] => 18
)
)
[3] => Array
(
[0] => 7
[1] => Array
(
[0] => 19
[0] => 20
)
)
[4] => Array
(
[0] => 8
[1] => Array
(
[0] => 21
)
)
)
where 0th index of innre mos array will contain 'eduHisRowId' value & the array on 1st index will contain 'repOrderId' values.
Thanks in advance...
Can I suggest a different solution? What about an array structure that looks like:
Array
(
[4] => Array
(
[0] => 15
)
[5] => Array
(
[0] => 16
[1] => 17
)
)
The keys are the eduHisRowId values and the value is an array of corresponding repOrderId values.
Creating this array would go like follows:
function consolidate($item, $key, $array) {
$rowId = $item['eduHisRowId'];
if(!array_key_exists($rowId, $array)) {
$array[$rowId] = array();
}
$array[$rowId][] = $item['repOrderId'];
}
$result = array();
array_walk($dataArray, 'consolidate', &$result);
$dataArray is your multidimensional array, the resulting array is in $result.
Reference: array_walk(), array_key_exists()
