Convert string values of associate array to integer

Question

I got an array as follows.

I need to convert the values as integer

array:17 [
  0 => array:2 [
    "c" => "gmail"
    "co" => "12"
  ]
  1 => array:2 [
    "c" => "dddd"
    "co" => "2"
  ]
  2 => array:2 [
    "c" => "mmmmm"
    "co" => "2"
  ]
  3 => array:2 [
    "c" => "dsf"
    "co" => "2"
  ]
  4 => array:2 [
    "c" => "aaaa"
    "co" => "1"
  ]
  5 => array:2 [
    "c" => "bbbb"
    "co" => "1"
  ]
  6 => array:2 [
    "c" => "ccc"
    "co" => "1"
  ]
  7 => array:2 [
    "c" => "yopmail"
    "co" => "1"
  ]
  8 => array:2 [
    "c" => "yahoo"
    "co" => "1"
  ]
]

I need to convert all values of the key co to integer ,where currently they are string.

Is this is the way to use the foreach,which didn't give me correct output

 foreach($getDashboardDetails as $getDashboardDetails)
    {
        $getDashboardDetails['co']=(int)$getDashboardDetails['co'];
    }

Hope Someone can help

The problem with your solution is that you can't use the same var name for the foreach item. Rename the variable after 'as' and use the renamed variable inside. — René Beneš

I think the for loop is more what are you looking for as you want to change the initial array.

for($i=0;$i<=count($getDashboardDetails)-1;$i++) {
    $getDashboardDetails[$i]["co"] = (int)$getDashboardDetails[$i]["co"];
    $i++;
}

Or you can use foreach with a key-value pair on both dimensions, but I don't find it neccessary.

This might help you on your way(assuming $getDashboardDetails is the source array):

foreach($getDashboardDetails as $key => $value) {
    foreach($value as $key1 => $value1) {
        if ($key1 === "co") {
            $getDashboardDetails[$key][$key1] = (int)$getDashboardDetails[$key][$key1];
        }
    }
}

Use below code to get it, your foreach is in incorrect foam.

$new_array = array();
foreach($getDashboardDetails as $key=>$value)
{
    $new_array[$key]=array("c"=>$value['c'], "co"=>(int)$value['co']);
}

Now you have $new_array with expected results.
