¿Qué es PHP?

PHP es uno de los lenguajes de programación más utilizados

PHP es un lenguaje de programación y significa Hypertext Preprocessor. Es a través del lenguaje PHP, y otros lenguajes como el HTML, que podemos crear páginas web. El lenguaje PHP es de código abierto, lo que significa que se puede utilizar de forma gratuita. De hecho, PHP ha alcanzado su popularidad al liderar la tecnología de código abierto. 

Un sitio web creado con HTML es un sitio web estático. Estático significa que siempre muestra el mismo contenido. HTML (lenguaje de marcado de hipertexto) es la base del código de cualquier sitio web, y, aunque este lenguaje se ha utilizado hasta hoy, existen otros lenguajes de programación mucho más avanzados. 

Por otro lado, un sitio web dinámico es capaz de cambiar su contenido y adaptarse a sus usuarios según la manera en que estos interactúan con el sitio web. Se pueden crear sitios web dinámicos utilizando el lenguaje PHP. Los usuarios puede interactuar con el sitio web de formas complejas, como comprar un producto o escribir un mensaje: esto es posible en los sitios web dinámicos. Todas las páginas web constan de una cierta cantidad  de código HTML, que sirve para que el navegador del usuario sepa interpretar el código fuente. Aparte de eso, el resto del contenido debe ser dinámico y generado por scripts.

¿Para qué sirve PHP?

Si alguna vez has descargado los archivos para una instalación de WordPress, habrás notado que hay varios archivos con la extensión .PHP. Esto se debe a que WordPress utiliza archivos PHP y comprende el lenguaje PHP.

PHP se ejecuta en un servidor, por lo que cada vez que escribes una dirección en tu navegador, PHP trabaja en segundo plano.

Para comunicarse con un ordenador, hay que utilizar un lenguaje que este entienda. El texto, el software, se llama “código fuente”.

Uno de los lenguajes de programación más populares es PHP. Si combinas MariaDB con PHP, puedes crear sitios web de todos los tamaños. 

Los scripts PHP pueden parecer incomprensibles, pero hacen un trabajo importante. PHP se encarga de que el código fuente se transforme en las páginas web que ves, llenas de texto, imágenes y otros contenidos que los humanos, incapaces de leer el código, podemos ver y utilizar.

Ejemplos de lenguaje PHP

Hablando de WordPress: cuando deseas iniciar sesión en tu panel de WordPress, se envía una solicitud de inicio de sesión al servidor. Luego, PHP se comunica con la base de datos y la habilita. Esto te permite iniciar la sesión.

Otro ejemplo, también relacionado con WordPress, es que PHP descarga el contenido de un sitio web o de una página web que quieras visitar. Normalmente, todo el contenido se almacena en una base de datos, pero pero el lenguaje PHP se comunica con la base de datos para hacerle saber que se necesita algún contenido. 

Hosting PHP con one.com

El hosting PHP con one.com te permitirá tener un sitio web fácil de usar y avanzado. Nuestra base de datos MariaDB y PHP constituyen la combinación ideal para desarrollar sitios web variados y ricos en contenido que permiten experiencias de usuario interactivas. 

Además, puedes utilizar estas herramientas para atraer a tus clientes y asegurarte de que pasen tiempo en tu web. En particular, puedes hacer que visitar tu tienda online sea un placer.  

Tanto PHP como MariaDB están incluidos en todas las suscripciones de espacio web con one.com. 

La importancia del lenguaje PHP

Puedes crear una tienda online con PHP y MariaDB. Gracias a PHP, puedes registrar cuando alguien ha añadido un artículo a la cesta de la compra. PHP también genera el código HTML, algo de texto, y probablemente también los gráficos que te permiten ver la cesta en la página de pago. También le debemos a PHP el poder enviar una confirmación de pedido al cliente después de que este haya realizado una compra. 

Para poder utilizar PHP, necesitas una base de datos en la que almacenar todos tus datos. Por eso ofrecemos MariaDB en one.com; funcionan perfectamente juntos.

La base de datos también almacena información sobre todos los productos o servicios adquiridos. Por lo tanto, esta permite que PHP recopile la información necesaria y envíe la confirmación del pedido a los clientes.
