Question: I am trying to search a multi-dimensional associative array and change a value after searching. Here is what my array looks like

```
 $arr=Array ( [0] => Array ( [1] => 
    Array ( [keyword] => 2014 
            [count] => 97 
            [percent] => 4.91 )))

```

So what I am trying to do is to search for keyword and if found then increase the count on that particular index where keyword was found. 

So I am trying to do something like:

```
if(in_array("2014", $arr))
{
//then add 100 to count that is 100+97

}

```

So what will be the best way to go about this. 

Note: I am trying to search a value in the array and **if found then update the value of count key on that particular index**. The last part is as important as first.

Answer: 
iterate through the dimensions of the array and change value if you found the key

```
foreach ($arr as $key => $val) {
    foreach ($arr[$key] as $keyy => $val) {
        foreach ($arr[$key][$keyy] as $keyyy => $val) {
            if($arr[$key][$keyy]['keyword'] == 2014){
                $arr[$key][$keyy]['count'] = $arr[$key][$keyy]['count']+100;
                break;
            }
        }          
    }       
}

```

hope it helps ;D
Your array

```
$arr=array( "0" => array( "1" => 
    array( "keyword" => 2014 ,
            "count" => 97, 
            "percent" => 4.91 ),
  "2"=> array( "keyword" => 2015,
            "count" => 5, 
            "percent" => 4.91 )));

```

Code 

```
foreach($arr as $key => &$val) {

    foreach($val as $mm => &$aa) {

        if("2014" == $aa['keyword']) {

            $aa["count"] =  $aa["count"]+ 100;
        }
    }
}

print_r($arr);

```
