Obtener el tipo de dato de una variable en PHP
Una función que nos resultará de gran utilidad a la hora de programar en PHP es la función gettype().
Con gettype() podemos conocer el tipo de dato de una variable en PHP. Pero, como te utiliza? Veamos un ejemplo:
$variable="Hola"; echo gettype($variable); //mostrara: string
Además de la función gettype(), existen otras funciones que se utilizan de forma similar a gettype(), pero sirven para comprobar si una variable es de un tipo determinado. Algunas de estas funciones son:
- is_array
- is_float
- is_int
- is_bool
- Etc.
Creo que no hace falta explicar que tipo de dato comprueba cada función!
