Type casting using string for type

Question

I have table settings with columns: value - varchar type contains setting value and type - enum type contains variable types "int", "string", "float". How can I use string from type column to cast value to this type?

I'm trying to do it in my model but it doesn't work:

public function getValueAttribute($value){
    return ($this->type)$value;
}

You have to use the settype() function :

<?php 

$var = 42;
var_dump($var);  //  int 42
$type = 'string';
settype($var, $type);
var_dump($var);  //  string '42'

Adapted to your code snippet :

public function getValueAttribute($value){
    settype($value, $this->type);
    return $value;
}
