I have this array:
Array
(
[0] => Array
(
[tag_id] => 1
)
[2] => Array
(
[tag_id] => 3
)
[22] => Array
(
[tag_id] => 44
)
[23] => Array
(
[tag_id] => 45
)
[25] => Array
(
[tag_id] => 47
)
[26] => Array
(
[tag_id] => 48
)
)
I'd like it to look something like this so its simpler for me to loop through and insert each value into a database:
Array
(
[0] => 1
[1] => 3
[2] => 44
[3] => 45
[4] => 47
[5] => 48
)
You can use array_map.
PHP 5.3 or higher:
$callback = function($value) {
return $value['tag_id'];
};
$result = array_map($callback, $array);
Below 5.3:
function collapseTagIds($value) {
return $value['tag_id'];
}
$result = array_map('collapseTagIds', $array);
Well, you could do this:
$new_array = array();
foreach($array as $key => $value)
{
$new_array[$key] = $value['tag_id'];
}
print_r($new_array);
In your case, you have just one index on $value. If you don't want to specify the index name just do it:
$new_array = array();
foreach($array as $key => $value) {
$new_array[$key] = reset($value);
}
print_r($new_array);

I have a Multidimensional array, I need to find if array have same value of 'brand' attribute then return its id.
I tried via some array functions but it didn't work.
What I Tried:
1)
$backwards = array_reverse($attribute);
echo '<pre>';
$last_item = NULL;
$i = 0;
foreach ($backwards as $current_item) {
if ($last_item === $current_item[$i]['value']) {
echo '<pre>'; print_r($current_item[$i]['value']);
}
$last_item = $current_item[$i]['value'];
echo '<pre>'; print_r($last_item);
$i++;
}
2)
$j = 1;
$i = 0;
foreach ($attributeValues as $attributeData) {
foreach ($attribute as $value) {
if($value[$i]['value'] == $value[$j]['value']) {
echo '<pre>'; print_r($value); die();
}
$j++;
}
}
All my solution's not worked, please help.
[0] => Array
(
[0] => Array
(
[name] => brand
[value] => 54
[id] => 5251
[price] => 15000.0000
)
[1] => Array
(
[name] => model
[value] => 1200
[id] => 5251
[price] => 15000.0000
)
)
[1] => Array
(
[0] => Array
(
[name] => brand
[value] => 54
[id] => 5250
[price] => 15000.0000
)
[1] => Array
(
[name] => model
[value] => 1200
[id] => 5250
[price] => 12000.0000
)
)
[2] => Array
(
[0] => Array
(
[name] => brand
[value] => 89
[id] => 518
[price] => 100.0000
)
[1] => Array
(
[name] => model
[value] => 12
[id] => 518
[price] => 100
)
)
If [name]=>brand and [name]=>model value's of first array is same as second array's value then return [id].
You need two for loop.
$result =[];
foreach ($arr as $key => $value) {
foreach($value as $v){
$result[$v['name']][] = $v['id'];
}
}
$result = array_map("array_unique", $result); // to make it unique
print_r($result);
// if you want to check ids for brand
//print_r($result['brand']);
Output:
Array
(
[brand] => Array
(
[0] => 5251
[1] => 5250
[3] => 518
)
[model] => Array
(
[0] => 5251
[1] => 518
)
)
Demo.
EDIT
Then you can group it by name and value of it
$result =[];
foreach ($arr as $key => $value) {
foreach($value as $v){
$result[$v['name']."|".$v['value']][] = $v['id'];
}
}
$result = array_map("array_unique", $result);
print_r($result);die;
Demo.
you can use foreach and iterate through the array
$res = [];
foreach($arr as $k => $v){
if($v[0]['name'] == $v[1]['name'])
$res[$v[0]['name']] = $v[0]['id'];
}
If you want to match the index value try this
foreach($arr as $k => $v){
if($v[0]['value'] == $v[1]['value'])
$res[] = $v[0]['id'];
}
Working example
This question already has answers here:
Merge row data from multiple arrays
(6 answers)
Closed 5 months ago.
here: Transforming array values in elements of a subarray using PHP I asked quite the same, but the arrays were flatter. I tried to adapt the code, but unfortunately without success.
How could I merge following arrays so the second array won't be added after the end of the first array, but each subarray of the first array will receive the correspondent values of subarrays of the second. In other words, I want to merge the subarrays. Here my example:
Array 01:
Array01 (
[0] => Array
(
[0] => 40292633
[1] => 412
)
[1] => Array
(
[0] => 41785603
[1] => 382
)
[2] => Array
(
[0] => 48792980
[1] => 373
)
[3] => Array
(
[0] => 44741143
[1] => 329
))
Array 02:
Array02(
[0] => Array
(
[0] => 3460581
[1] => 1407424B1
[2] => 951753
)
[1] => Array
(
[0] => 3484251
[1] => 1028325B1
[2] => 159357
)
[2] => Array
(
[0] => 3519102
[1] => 0586365A1
[2] => 456654
)
[3] => Array
(
[0] => 3529714
[1] => 1059876A1
[2] => 852258
))
Final array:
finalArray(
[0] => Array
(
[0] => 40292633
[1] => 412
[2] => 3460581
[3] => 1407424B1
[4] => 951753
)
[1] => Array
(
[0] => 41785603
[1] => 382
[2] => 3484251
[3] => 1028325B1
[4] => 159357
)
[2] => Array
(
[0] => 48792980
[1] => 373
[2] => 3519102
[3] => 0586365A1
[4] => 456654
)
[3] => Array
(
[0] => 44741143
[1] => 329
[2] => 3529714
[3] => 1059876A1
[4] => 852258
))
Many thanks in advance!
try this code
function merge_arrays($a1, $a2) {
return array($a1, $a2);
}
$result = array_map("merge_arrays", $a1, $a2);
foreach($result as $nr)
{
$nres[] = array_merge ($nr[0], $nr[1]);
}
Try this:
$result = array();
$keys = array_unique( array_merge(array_keys($arr1), array_keys($arr2)) );
foreach($keys as $key) {
if( !array_key_exists($key, $arr1) ) {
$result[$key] = $arr2;
} else if( !array_key_exists($key, $arr2) ) {
$result[$key] = $arr1;
} else {
$result[$key] = array_merge($arr1[$key], $arr2[$key]);
}
}
It does not assume that both arrays have the same keys.
If you'd like to use array_map, this is an equivalent solution:
$keys = array_unique( array_merge(array_keys($arr1), array_keys($arr2)) );
$result = array_map(function($key) use ($arr1,$arr2) {
if( !array_key_exists($key, $arr1) ) {
return $arr2;
} else if( !array_key_exists($key, $arr2) ) {
return $arr1;
}
return array_merge($arr1[$key], $arr2[$key]);
},
$keys);
If you're sure both arrays have the same keys, you can try this:
$result = array();
foreach($arr1 as $key => $arr1val) {
$result[$key] = array_merge($arr1val, $arr2[$key]);
}
I've an array in php something like below
Array
(
[0] => Array
(
[0] => 40173
[1] => 514081
[2] => 363885
[3] => 891382
),
[1] => Array
(
[0] => 40173
[1] => 5181
[2] => 385
[3] => 891382
)
)
Now I want to remove the parents indexes 0,1... and finally want to get all the values (only unique values).
Thanks.
One possible approach is using call_user_func_array('array_merge', $arr) idiom to flatten an array, then extracting unique values with array_unique():
$new_arr = array_unique(
call_user_func_array('array_merge', $old_arr));
Demo. Obviously, it'll work with array of any length.
$startArray = Array
(
[0] => Array
(
[0] => 40173
[1] => 514081
[2] => 363885
[3] => 891382
),
[1] => Array
(
[0] => 40173
[1] => 5181
[2] => 385
[3] => 891382
)
);
//Edited to handle more the 2 subarrays
$finalArray = array();
foreach($startArray as $tmpArray){
$finalArray = array_merge($finalArray, $tmpArray);
}
$finalArray = array_unique($finalArray);
Using RecursiveArrayIterator Class
$objarr = new RecursiveIteratorIterator(new RecursiveArrayIterator($yourarray));
foreach($objarr as $v) {
$new_arr[]=$v;
}
print_r(array_unique($new_arr));
Demo
OUTPUT:
Array
(
[0] => 40173
[1] => 514081
[2] => 363885
[3] => 891382
[5] => 5181
[6] => 385
)
$new_array = array_merge($array1, $array2);
$show_unique = array_unique($new_array);
print_r($show_unique);
array_merge is merging the array's, array_unique is removinge any duplicate values.
Try something like this:
$new_array = array();
foreach($big_array as $sub_array) {
array_merge($new_array, $sub_array);
}
$new_array = array_unique($new_array);
(code not tested, this just a concept)
Try this:
$Arr = array(array(40173, 514081, 363885, 891382),
array(40173,5181, 385,891382));
$newArr = array();
foreach($Arr as $val1)
{
foreach($val1 as $val2)
{
array_push($newArr, $val2);
}
}
echo '<pre>';
print_r(array_unique($newArr));
Output:
Array
(
[0] => 40173
[1] => 514081
[2] => 363885
[3] => 891382
[5] => 5181
[6] => 385
)

I have an array like this and it can contain multiple values:
Array
(
[rpiid] => Array
(
[1] => 86
)
[sensor_id] => Array
(
[1] => 1
)
[when] => Array
(
[1] => 2014-02-24
)
[val] => Array
(
[1] => 000
)
[train] => Array
(
[1] => True
)
[valid] => Array
(
[1] => False
)
[button] => update
)
Of course, here there is only the number 1 each time but sometimes I have 0, 1, 2 and a value associated. This is because I get this from a GET from multiple forms.
How can I transform this array into
Array
(
[0] => Array
(
[rpiid] => 86
[sensor_id] => 1
...
Thanks,
John.
if your array is $get
$newArray = Array();
foreach($get as $secondKey => $innerArray){
foreach($value as $topKey => $value) {
$newArray[$topKey][$secondKey] = $value;
}
}
This should work
$new_array = array();
foreach($first_array as $value => $key){
$new_array[$key] = $value[1];
}
Sure you can, take a look at this small example:
$a = [ 'rpid' => [1], 'cpid' => [2,2] ];
$nodes = [];
foreach($a as $node => $array) {
foreach($array as $index => $value) {
if(empty($nodes[$index]))
$nodes[$index] = [];
$nodes[$index][$node] = $value;
}
}
print_r($nodes):
Array
(
[0] => Array
(
[rpid] => 1
[cpid] => 2
)
[1] => Array
(
[cpid] => 2
)
)
I'm having two arrays in PHP as follows:
Array1 ( [1] => Array ( [0] => 16 )
[2] => Array ( [0] => 17 [1] => 29 )
[3] => Array ( [0] => 30 [1] => 31 )
) Total Element Count: 5
Array2 ( [1] => Array ( [0] => 21 )
[2] => Array ( [0] => 22 )
[3] => Array ( [0] => 23 )
[4] => Array ( [0] => 24 [1] => 25 )
[5] => Array ( [0] => 43 [1] => 44 )
) Total Element Count: 7
I want to pair above two arrays depending on count of first array, that means, first five elements of Array2 should get mixed with Array1 with outer 1D keys remaining intact.
Output should be as follows:
Output Array( [1] => Array ( [0] => 16 [1] => 21)
[2] => Array ( [0] => 17 [1] => 29 [2] => 22)
[3] => Array ( [0] => 30 [1] => 31 [2] => 23 )
[4] => Array ( [0] => 24 [1] => 25 )
)
If you want to avoid E_STRICT warnings:
function combine(array $arr1, array $arr2) {
$ret = array();
foreach ($arr1 as $k => $v) {
if (!array_key_exists($k, $ret)) {
$ret[$k] = array();
}
$ret[$k][] = $v;
}
foreach ($arr2 as $k => $v) {
if (!array_key_exists($k, $ret)) {
$ret[$k] = array();
}
$ret[$k][] = $v;
}
return $ret;
}
If you prefer a shorter version:
function combine(array $arr1, array $arr2) {
$ret = array();
foreach ($arr1 as $k => $v) {
$ret[$k][] = $v;
}
foreach ($arr2 as $k => $v) {
$ret[$k][] = $v;
}
return $ret;
}
