• how to convert array values from string to int? 12 answers

I have a array like this:

array (size=3)
  'money' => string '16' (length=2)
  'str' => string '45' (length=2)
  'intl' => string '0' (length=1)

I want to convert string values to int like this:

array (size=3)
  'money' => int 16
  'str' => int 45
  'intl' => int 0

I tried to use foreach method:

$newuserattri=[];
foreach ($userattri as $key => $var) {
    $userattri[$key] = (int)$var;
    $newuserattri[]=$userattri[$key];
}
var_dump($newuserattri);

But that dident work, because now I dont have array value names

array (size=3)
  0 => int 16
  1 => int 45
  2 => int 0

</div>

You were actually close! You have to add them to the array with their original key like this:

$newuserattri = [];
foreach ($userattri as $key => $value) {
    $newuserattri[$key] = (int)$value;
}
var_dump($newuserattri);
