changing array values recursively in PHP

Question

I'm trying to change the values of an array recursevely and all the examples that I've seen in stackoverflow don't fit for what I want so far.

Basically, I want to translate a boolean to String.

foreach($this->data as $key=>$value)
{
    if (is_bool($value))
    {
        $this->data[$key] = var_export($value, true);
    }       
}

This works just in the first level of the array. Also, I've tried to change the values with array_walk_recursive with no success as well.

Thanks in advance.

Answer 1

array_walk_recursive() should do this perfectly easily

array_walk_recursive(
    $myArray,
    function (&$value) {
        if (is_bool($value)) {
            $value = 'I AM A BOOLEAN';
        }
    }
);
