Normalmente cuando hacemos uso de las clases seguimos la siguiente sintaxis.<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n Pero hay que darse cuenta cuantas veces hemos hecho referencia al objeto $humano<\/em><\/strong>. Ser\u00eda mucho m\u00e1s pr\u00e1ctico si llam\u00e1semos una \u00fanica vez al objeto $humano<\/em><\/strong> y luego ir pas\u00e1ndole los distintos m\u00e9todos (setNombre,<\/em> setApellidos<\/em><\/strong>…). De hecho si se ha trabajado con algunos frameworks como Laravel,<\/strong> se llama una s\u00f3la vez al objeto y luego se van concatenando los distintos m\u00e9todos que se van utilizando.<\/p>\n\n\n\n Para lograr \u00e9sto, todos los m\u00e9todos que no devuelvan valor los vamos a hacer que devuelvan un valor, que va a ser el mismo objeto, para lo cual vamos a escribir la sintaxis dentro de la funci\u00f3n return $this; <\/em><\/strong>de la siguiente manera.<\/p>\n\n\n\n Una vez que ejecutemos el m\u00e9todo setNombre()<\/em><\/strong>, el objeto vuelve a ser $humano, por lo cual ya no necesitamos llamar nuevamente al objeto humano si queremos ejecutar otro m\u00e9todo como setApellidos()<\/em><\/strong>.<\/p>\n\n\n\n Ejm<\/strong><\/p>\n\n\n\n Hacer esto se ve mucho m\u00e1s limpio y vamos a tener el c\u00f3digo mucho m\u00e1s organizado.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Normalmente cuando hacemos uso de las clases seguimos la siguiente sintaxis.
