PHP Searching multidimensional associative array - php

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 1

you can use that code:
$arr = Array(
0 => Array(
1 => Array(
'keyword' => 2014,
'count' => 97,
'percent' => 4.91
)
)
);
foreach ($arr as &$arr1) {
foreach ($arr1 as &$arr2) {
if (2014 == $arr2['keyword']) {
$arr2['count'] += 100;
}
}
}
unset($arr2, $arr1);
Result:
array(1) {
[0]=>
array(1) {
[1]=>
array(3) {
["keyword"]=>
int(2014)
["count"]=>
int(197)
["percent"]=>
float(4.91)
}
}
}

Answer 2

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

Answer 3

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);
