php add some value on specific location in multidimensional array - php

Question

I have array like this
Array ([0] => Array ( [user_id] => 21 [email] => momod#modara.com [brand] => Array ( [0] => GOFUEL_W [1] => GOFUEL_USD_W ) ) [1] => Array ( [user_id] => 22 [email] => hemisphere#modara.com [brand] => Array ( [0] => GOFUEL_W ) ) [2] => Array ( [user_id] => 23 [email] => madoka#modara.com [brand] => Array ( [0] => GOFUEL_W [1] => GOFUEL_USD_W [2] => GOFUEL_BGD_W ) ) )
i want to locate user_id 22 and put this value "GO_FUEL_SGD_W" on brand, what should i do, so the view of array will look like this
Array ([0] => Array ( [user_id] => 21 [email] => momod#modara.com [brand] => Array ( [0] => GOFUEL_W [1] => GOFUEL_USD_W ) ) [1] => Array ( [user_id] => 22 [email] => hemisphere#modara.com [brand] => Array ( [0] => GOFUEL_W => [1] =>GO_FUEL_SGD_W ) ) [2] => Array ( [user_id] => 23 [email] => madoka#modara.com [brand] => Array ( [0] => GOFUEL_W [1] => GOFUEL_USD_W [2] => GOFUEL_BGD_W ) ) )

Answer 1

Just use loop:
foreach($array as &$item)
{
if(array_key_exists('user_id', $item) &&
$item['user_id']==22 &&
array_key_exists('brand', $item) &&
!in_array('GO_FUEL_SGD_W', $item['brand']))
{
$item['brand'][] = 'GO_FUEL_SGD_W';
}
}

Answer 2

A simple foreach loop will do the job:
foreach($myarray AS &$subarray) {
if($subarray['user_id'] == 22) {
$subarray['brand'][] = "GO_FUEL_SGD_W";
break;
}
}

Answer 3

You will need to iterate over the array and look for the element you're searching for.
foreach ($array as &$element) {
if ($element['user_id'] != 22)
continue;
$element['brand'][] = "GO_FUEL_SGD_W";
break;
}
With continue; all elements will be skipped, who have $element['user_id'] != 22 (and so none of the code after the continue; will be applied to them!).
Also it will end the loop once the requested element is reached and modified, thanks to break;.

Answer 4

$array= //your array;
foreach($array as $x){
if($x['user_id']=='22'){
$x['brand'][]='GO_FUEL_SGD_W';
break;
}
}
