- Vamos a realizar un recorrido de un array asociativo de varios niveles.
- Realizaremos un estudio del array y luego lo recorreremos
- Dado un fichero que contiene un array asociativo
- El array contiene información de cantantes y de cada cantante su nombre, su década y canciones que tiene
- Se trata que trabajes en dos aspectos que se complementas
- Entender y explicar el contenido del array, es decir si es asociativo o indexado y los indices que tiene. Si una posición es un array a su vez procedemos a explicarlo igualmente
- Posteriormente lo recorreremos mostrando información de los cantantes y para cantante sus canciones
- Para hacer esta parte facilito un pequeño css y consistiría en aplicar el div cantante y el div canciones
- Ficheros
Artista.pdf Este fichero es un css para el ejercicios

- A partir de él podemos mostrar la siguiente imagen que describe el aray
- Observamos que en primera instancia tengo un array asociativo de 6 índices cuyos valores son
185711, 32841, 84062, 84430, 84221, 118504
- Cada posición tiene como valor un array asociativo de 4 posiciones cuyos índices tiene los valores
name decades link canciones
- La posición name directamente tiene un valor string que es el nombre del artista
