I have two array.
1st array is $newarray = ('489289', '536516', '332833', '536516')
2nd array is
$rockin = array(
'489289' => array('536516','value1'),
'332833' => array('536516'),
);
I want to delete some value of $newarray.
Suppose we are looping from $newarray
Initially 489289 is assigned value.
I want to check whether the value associated to 489289 from $rockin array (i.e. value1 or 536516) also exist in $newarray.
If there is exist 'value1' or '536516' in $newarray then, delete 489289 from array!
So in above case 489289 would be deleted (from $newarray)
AS 536516 is associated value of 489289 in $rockin array AND 536516 also exist in $newarray
Till now I have tried this code
foreach ($newarray as $group_id) {
foreach ($rockin as $myfrcikingcl) {
foreach ($myfrickingcl as $myfrickingleader) {
if($group_id==$myfrickingleader)
{
unset($newarray[$group_id]);
}
}
}
}
This is what I understood you want to do:
$newarray = array('489289', '536516', '332833', '536516');
$rockin = array(
'489289' => array('536516','332833'),
'332833' => array('536516'),
);
foreach ($rockin as $array) {
foreach ($array as $value) {
if (in_array($value, $newarray)) {
$key = array_search($array, $rockin);
$newarray = array_diff($newarray, array($key));
}
}
}
foreach ($newarray as $k => $v) {
if(is_array($rockin[$v])){
foreach ($rockin[$v] as $key => $value) {
if(in_array($value, $newarray)){
unset($newarray[$k]);
}
}
}
}
You're using $group_id as a key, but it's a value. You have to unset by key, like this:
foreach ($i = 0; $i < count($newarray); $i++) {
foreach ($rockin as $myfrcikingcl) {
foreach ($myfrickingcl as $myfrickingleader) {
if ($newarray[$i] == $myfrickingleader) {
unset($newarray[$i]);
}
}
}
}

I have 2 arrays
$array1 = array(22,193,124);
$array2 = array(array('id'=>22, 'count'=> 1), array('id'=>124, 'count'=>2));
Now I need to search in $array2 for id from $array1 and if found to increment the count value and also add to the array the one's which are not found with a count as 1 so my resulting array would be
$arr = array(array('id'=>22, 'count'=> 2), array('id'=>124, 'count'=>3), array('id'=>193, 'count'=>1));
any help would be appreciated
The current code which I tried is
if($array2){
foreach($array1 as $array){
if(in_array($array, array_column($array2, 'id'))){
$wa_array['count'] += 1;
} else {
$wa_array['id'] = $array;
$wa_array['count'] = 1;
}
}
} else {
foreach($array1 as $array){
$wa_array['id'] = $array;
$wa_array['count'] = 1;
}
}
This may be something you are looking for -
$array1 = array(22,193,124);
$array2 = array(array('id'=>22, 'count'=> 1), array('id'=>124, 'count'=>2));
foreach($array1 as $key=>$digit)
{
$keyFound = array_search($digit, array_column($array2, 'id'));
if($keyFound === false)
{
array_push($array2, ['id'=>$digit, 'count'=>1]);
}
else
{
$array2[$keyFound]['count']++;
}
}
print_r($array2);
The question is not so clear, so I will go with my understanding : You need to check if values inside the first array are in the second array. If yes, increment the count value of that second array, if not, create that element with the value of 1.
This code is not tested, hope this can help find the good solution.
foreach($array1 as $value){
searchForId($value,$array2);
}
function searchForId($id, $array) {
foreach ($array as $key => $val) {
if ($val['id'] === $id) {
$val['count'] += 1;
}else{
array_push(array('id'=>$id,'count'=>1))
}
}
return null;
}
you should loop through $array2, not $array1. Finding the value in array_column($array2, 'id') doesn't tell you the index of the array element to increment.
foreach ($array2 as &$item) {
if (in_array($item['id'], $array1)) {
$item['count']++;
}
}
Note that you have to use &$item to make this a reference to the original array element, so that modifying it will update $array2. Otherwise, $item would be a copy of the array element.
If $array1 is large, it would be better to convert it to an associative array so you can test membership more efficiently.
$array1_assoc = array_flip($array1);
Then the test in the loop becomes:
if (isset($array1_assoc[$item['id']]) {
Check this one. NOTE: But this has O(n^2) complexity.
$array1 = [22,193,124];
$array2 = [['id'=>22, 'count'=> 1], ['id'=>124, 'count'=>2]];
foreach ($array1 as $value) {
$isFound = false;
foreach ($array2 as &$item) {
if ($value == $item['id']) {
$item['count']++;
$isFound = true;
continue;
}
}
if ($isFound == false) {
$array2 [] = ['id'=>$value, 'count'=> 1];
}
}
var_dump($array2);
Tried using array_values but it only temporary.
controller
foreach($rows as $key => $value)
{
array_values($value);
//dd shows the key changes to [0], [1], [2] and so on
}
You can do it like this,
$rows = array_map(function($v){return array_values($v);}, $rows);
Something like this should work:
$new = [];
foreach($rows as $key => $value)
{
array_values($value);
$sub = [];
foreach ($value as $subKey => $subValue) {
$subKey = $key;
$sub[$key] = $subValue;
}
$new[$key] = $sub;
//dd shows the key changes to [0], [1], [2] and so on
}
Then return $new instead of $rows.
Since you're using laravel you can also do:
$rows = collect($rows)->map(function ($value) {
return Arr::accessible($value)?collect($value)->values()->all():$value;
})->all();
If you are trying to change the associative array to an indexed array, do this:
$array = array_values($array);
I have foreach loop like:
foreach($attributes as $key => $value)
{
$option[] =["$value->name"=>"$value->value"]; //it is like ["color"=>"red"]
}
I want to merge $option[0], $option[1] and so on.... How to merge that ?
I tried:
for($i=1;$i<$count;$i++)
{
$option = array_merge($option[0],$option[$i]);
}
If you want a merged version, try this (you need only 1 loop):
$merged_options = array();
foreach($attributes as $key => $value)
{
$option[] =["$value->name" => "$value->value"];
$merged_options[$value->name] = $value->value;
}
This code should hopefully loop through each of your current arrays and reconstruct it to a multi-dimensional array.
foreach($attr as $k=>$v):
$temp = array();
$i = 0;
while(count($k) != $i):
array_push($temp, $k[$i] => $v[$i]);
$i++;
endwhile;
array_push($attr, $temp);
endforeach;
Hope it helped.
Why not you use something like this:
foreach($attributes as $key => $value)
{
$option[$value->name] =$value->value;
}
I found a way to search my multidimensional array and output the result and it works, however it only finds the first match and stops. If I have more than one match in the array I want to be able to show them all.
My array looks like this (the first layer of keys goes from 0, 1, 2 etc):
Array
(
[0] => Array
(
[mydevice] => blahblah
[ipadd] => 10.10.10.209
[portnum] => 16040
)
function searcharray($value, $key, $array) {
foreach ($array as $k => $val) {
if ($val[$key] == $value) {
return $k;
}
}
return null;
}
$myoutput = searcharray($ptn2, mydevice, $newresult);
I can then echo the results using something like $newresult[$myoutput][mydevice].
However if I have more than one entry in the array with a matching data in the 'mydevice' key it doesn't return them (just the first one).
That is because return breaks the function. You could use something like this:
function searcharray($value, $key, $array) {
$result = array();
foreach ($array as $k => $val) {
if ($val[$key] == $value) {
$result[] = $k;
}
}
return $result;
}
Now you will always get an array as result - empty if nothing was found. You can work with this like this e.g.
$mydevicekeys = searcharray($ptn2, "mydevice", $newresult);
foreach ($mydevicekeys as $mydevicekey) {
// work with $newresult[ $mydevicekey ]["mydevice"]
}
So add the results to an array :)
function searcharray($value, $key, $array) {
$res = array();
foreach ($array as $k => $val) {
if ($val[$key] == $value) {
$res[] = $key;
}
}
return $res;
}
I'm trying to fill an array with my foreach loop, but I don't get it to work. What am I doing wrong?
$a = array();
$activities = Project::getProjectnames($_DB, $projectnaam);
if(!empty($activities)) {
foreach($activities as $k => $v) {
$a .= array_fill($v['name']);
}
}
All I get back is the string Array...
you're concatenating a string there. You need to push the item into the array.
foreach($activities as $k => $v) {
$a[] = $v['name'];
}
