📝▶️ Create and run a PHP file
Create file: touch hola.php
Content of hola.php:
<?php
echo "Hola Mundo PHP\n";
PHP can be run in 2 ways: as a system file, which makes it useful for local scripts—you could replace bash scripts, for example—and in a web server. PHP already comes with an embedded server, but it’s more common to use it with Apache or Nginx.
Run locally:
php hola.php
Embedded server:
php -S localhost:8000
🟦 Basic example in PHP
What it does:
- Defines the name of the query parameter.
- Gets the query parameter value from the URL.
-
$_GETis used to access query parameters. -
htmlspecialcharsis used for security, to prevent XSS attacks by converting special characters like<and>into HTML entities.
-
- It draws the value received through the query parameter inside the
<h1>tag.
📝 Create file: touch index.php
▶️ Content of index.php:
<?php
$paramName = 'username';
$textoRecibido = isset($_GET[$paramName])
? htmlspecialchars($_GET[$paramName])
: "No se ha proporcionado un nombre.";
?>
<!DOCTYPE html>
<html lang="es">
<head>
<meta charset="UTF-8">
<title>Mensaje Recibido</title>
</head>
<body style="text-align: center">
<h1>Nombre de usuario en la URL: "<?php echo $textoRecibido; ?>"</h1>
