I have this kind of array.
Array
(
[0] => Array
(
[supplierID] => 1
[parkTypeID] => 1
[cost] => 17
)
[1] => Array
(
[supplierID] => 2
[parkTypeID] => 1
[cost] => 65
)
[2] => Array
(
[supplierID] => 2
[parkTypeID] => 2
[cost] => 30
)
)
I want to combine elements which has same value for supplierID like this. Each key name's value has set in new array's keys.
Array
(
[1] => Array
(
[1] => 17
)
[2] => Array
(
[1] => 65
[2] => 30
)
)
Try
$r = array();
foreach ($array1 as $x) {
if (array_key_exists($x['supplierID'], $r)
$r[$x['supplierID']][$x['parkTypeID']] = $x['cost'];
else
$r[$x['supplierID']] = array($x['parkTypeID'] => $x['cost']);
}
This will iterate over the initial array $array1 and create a new array $r with the desired information.
For each element in the original array we check whether supplierID exists in $r.
If so, we just append the new correlation between the parkTypeID and the cost to the existing values.
If not, we add the supplierID to $r and assign it an array with only this pair of parkTypeID and cost.
A simplified version of the above code that relies on php to initialize an unset array index to an empty array when necessary is
$r = array();
foreach ($array1 as $x)
$r[$x['supplierID']][$x['parkTypeID']] = $x['cost'];
$arr_res = array_reduce($arr, function($t, $v) {
if (!isset($t[$v['supplierID']]))
$t[$v['supplierID']] = array();
$t[$v['supplierID']][] = $v['cost'];
return $t;
} , array());

I have a multi dimensional output array with following structure :
Array
(
[0] => Array
(
[id] => 5925
[fb_id] => 123
[description] =>
[video] =>
[thum] =>
)
[1] => Array
(
[id] => 7060
[fb_id] => 2344
[description] =>
[video] =>
[thum] =>
)
[2] => Array
(
[id] => 6579
[fb_id] => 123
[description] =>
[video] =>
)
)
Here, I want to limit the sub array count to 5 for all users with same 'fb_id'. Only 5 sub arrays for each fb_id should be in final output array. Any help would be appreciable.
The original array being used here is called $original and this code will reduce it down and produce a new array called $new. Feel free to change the variable names as appropriate.
$new = [];
$count = [];
foreach ($original as $element) {
$fbid = $element['fb_id'];
if (!isset($count[$fbid])) {
$count[$fbid] = 0;
}
if ($count[$fbid] < 5) {
$new[] = $element;
$count[$fbid]++;
}
}
// New array with limited sub-arrays
print_r($new);

I have an array of objects, each object consists of an id and an organisation. It looks like this
Array (
[0] => stdClass Object (
[id] => 2 [organisation] => org1
)
[1] => stdClass Object (
[id] => 4 [organisation] => org2
)
[2] => stdClass Object (
[id] => 1 [organisation] => org3
)
)
I need to convert it into a simple associative array ([id]=>organisation,...) so the above example would look like this
Array (
[2] => org1
[4] => org2
[1] => org3
)
Greatful for any thoughts
Loop through it using a foreach statement and append it to another array.
$finished = [];
foreach($array as $arr) {
$finished[$arr->id] = $arr->organisation;
}
$result = array();
foreach($array as $arr) {
$result[$arr->id] = $arr->organisation;
}
echo "<pre>";print_r($result);

Is there any simple solution to convert php mysql result change array structure with foreach or any method ?
Current result
Array
(
[1033] => stdClass Object
(
[id] => 1033
[plugin] => kooyke
[name] => kooyduration
[value] => 13
)
[1029] => stdClass Object
(
[id] => 1029
[plugin] => kooyke
[name] => kooyendpoint
[value] => http://localhost/public/data/
)
[1030] => stdClass Object
(
[id] => 1030
[plugin] => kooyke
[name] => kooylogin
[value] => ryrtrtr68fds876fdsf876fsd87fd
)
)
Expecting result
Array
(
[kooyduration] => 13
[kooyendpoint] => http://localhost/public/data/
[kooylogin] => ryrtrtr68fds876fdsf876fsd87fd
)
the code trying to convert
foreach($result as $value){
$expresult[] = $value['value'];
}
print_r($expresult);
Bellow code blocks may help you.
$i = 0;
$last_arr = array();
$new_arr = array();
foreach($my_array as $key=>$val)
{
$new_arr[$val->name] = $val->value;
}
array_push($last_arr,$new_arr);
You can not use like $value['value'], should be $value->value because of object. And push new array your name index. Try following:
$expresult = array();
foreach($result as $value)
{
$expresult[$value->name] = $value->value;
}

My foreach loop begins at last element. I have an array $gridRows within object $grid that is currently set up like so:
$grid
gridRows
2
gridCells
1
2
3
3
gridCells
1
2
gridRow 2 has 3 gridCells in it and gridRow 3 has 2 gridCells.
However, when I iterate through it, the first foreach goes to gridRow 3 first. It still iterates over gridRow 2 but it does it second.
$gridRows = $grid->getGridRows();
foreach ($gridRows as $rowKey => $rowValue) {
$gridCells = $rowValue->getGridCells();
foreach ($gridCells as $cellKey => $cellValue) {
// do something
}
}
What gives? I tried using sort($grid, SORT_NUMERIC) but I get the same effect.
Result of print_r($gridRows):
Array (
[3] => GridRow Object (
[gridCells:GridRow:private] => Array (
[2] => GridCell Object ( ... )
[1] => GridCell Object ( ... )
)
)
[2] => GridRow Object (
[gridCells:GridRow:private] => Array (
[1] => GridCell Object ( ... )
[2] => GridCell Object ( ... )
[3] => GridCell Object ( ... )
)
)
)
It seems to being an object not an array. Use a numerically indexed array to maintain the order you want.

I've looked on this site and have found a few examples of merging arrays but to be honest, I'm not sure which one is right for me.
I am having a difficult time trying to merge these arrays. I've tried array_combine and array_merge but I am not having any luck.
What I need is a single array with the output like this:
Array
(
[0] => Array
(
[UnitNo] => 91
[Name] => Receiving
[ActivityNo] =>
[Active] => 2
[CallNo] =>
[CallStatusNo] =>
[Assigned] =>
[UnitId] => 2
)
[1] => Array
(
[UnitNo] => 83
[Name] => Shipping
[ActivityNo] =>
[Active] =>
[CallNo] =>
[CallStatusNo] =>
[Assigned] =>
[UnitId] => 1
)
)
These are the two arrays that I need to merge together based on the UnitId that should form a complete array like the one above. I just don't know how to do this. If someone could direct me a bit, I would be grateful.
// Array #1
Array
(
[0] => Array
(
[UnitId] => 2
[UnitNo] => 91
[Name] => Receiving
[Active] => 4
)
[1] => Array
(
[UnitId] => 1
[UnitNo] => 83
[Name] => Shipping
[Active] => 4
)
)
// Array #2
Array
(
[0] => Array
(
[UnitId] => 2
[ActivityNo] => 1
[CallNo] => 1
[CallStatusNo] => 1
[Assigned] => 1
)
[1] => Array
(
[UnitId] => 1
[ActivityNo] => 11
[CallNo] => 2
[CallStatusNo] => 1
[Assigned] => 1
)
)
This isn't a case where you can just use a php function and call it good - you will have to do some custom logic of your own.
This would work, but only if both $array1 and $array2 have the same items at each index.
$array1;
$array2;
$mergedArray;
for ($i=0; $i++; $i < count($array1) - 1) {
//first add all the values from array1
$mergedArray[$i] = $array1[$i];
foreach($array2[$i] as $array2Key=>$array2Value){
//now check for missing key/values that are in array2 but not in array1
if (array_key_exists($array2Key, $array1[$i]) == false) {
// the key does not exist in array1, so add it to mergedArray
$mergedArray[$i][$array2Key] = $array2Value;
}
}
}
It would be safer if your arrays were associative arrays, indexed by a unique value.
