## Condicionales
|
||
|
|
|
||
|
|
Los condicionales en PHP se escriben usando la sintaxis `if` , `elseif` , `else` . El uso de condicionales le permite realizar diferentes acciones dependiendo de las diferentes entradas y valores proporcionados a una página en tiempo de ejecución. En PHP, los condicionales a menudo se denominan estructuras de control.
