For instance, how to convert the following array:

$array1 = array("value1" => "20", "value2" => 40, array("value3" => 60));

To:

$array1 = array("value1" => "20", "value2" => "40", array("value3" => "60"));

You can write recursive function eg.:

function strArr($inp){
    $res=array();
    foreach($inp as $k=>$v){
        if(is_array($v)) $res[$k]=strArr($v);
        else $res[$k]=strval($v);
    }
    return $res;
}
$array1 = array("value1" => "20", "value2" => 40, array("value3" => 60));

$array2 = strArr($array1);

Converting every element to a string without support for lambda functions:

array_walk_recursive($array, 'strval');

Converting every element to a string without support for lambda functions: array_walk_recursive($array, create_function('&$value', '$value = (string)$value;')); Simply strval as callback won't work.
