INTRODUCCIÓN A PDOY SQL
● Bases de Datos
● Sistemas manejadores de
BasesDatos
● SQL
● mysqli y otraslibrerías
● PDO

CONEXIÓNPDO
<?php
try {
$pdo = new PDO("mysql:host=localhost;
dbname=cursophp";
"root","");
$pdo->setAttribute(PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION);
} catch(Exception $e) {
echo $e->getMessage();
}
?>
<html>
<head>
<title>Base de Datos</title>
</head>
<body>
<div class="container">
<h1>Base de Datos</h1>
<ul>
<li>
<a href="list.php">Lista de Usuarios</a>
</li>
<li>
<a href="add.php">Añadir Usuario</a>
</li>
</ul>
</div>
</body>
</html>
<?php
$dbHost =
'rdsindentirmysql.crqhpy7ee5r1.sa-
east-1.rds.amazonaws.com';
$dbName = ‘upa2';
$dbUser = ‘admin';
$dbPass = 'Sistemas2020';
try {
$pdo = new
PDO("mysql:host=$dbHost;dbname=$dbName
", $dbUser, $dbPass);
$pdo->setAttribute(PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION);
} catch(Exception $e) {
echo $e->getMessage();
} index.php config.php

INSERTAR DATOS CONPDO ● HTML Form
● $_GET, $_POST
<?php
require_once 'config.php';
$result = false;
if (!empty($_POST)) {
$name = $_POST['name'];
$email = $_POST['email'];
$password = md5($_POST['password']);
// Validate
$sql = "INSERT INTO users(name, email,
password) VALUES (:name, :email,
:password)";
$query = $pdo->prepare($sql);
$result = $query->execute([
'name' => $name,
'email' => $email,
'password' => $password
]);}?>
add.php
<html><head><title>Bases de Datos
Agregar</title></head><body>
<h1>Agregar Usuario</h1>
<a href="index.php">Inicio</a>
<?php
if ($result) {
echo '<div class="alert alert-
success">Success!!!</div>';}?>
<form action="add.php" method="post">
<label for="name">Nombre</label>
<input type="text" name="name"
id="name"><br>
<label for="email">Correo</label>
<input type="text" name="email"
id="email"><br>
<label for="password">Clave</label>
<input type="password" name="password"
id="password"><br>
<input type="submit" value="Guardar" >
</form></div></body></html>

LEER DATOS CONPDO
<?php
require_once 'config.php';
$queryResult = $pdo-
>query("SELECT * FROM
users");
?>
<html><head>
<title>Bases de Datos Listar</title>
</head><body>
<h1>Listar Usuarios</h1>
<a href="index.php">Inicio</a>
<table class="table"><tr>
<th>Nombre</th>
<th>Correo</th>
<th>Editar</th>
<th>Borrar</th></tr>
<?php
while($row = $queryResult-
>fetch(PDO::FETCH_ASSOC)) {
echo '<tr>';
echo '<td>' . $row['name'] . '</td>';
echo '<td>' . $row['email'] . '</td>';
echo '<td><a href="update.php?id=' .
$row['id'] . '">Editar</a></td>';
echo '<td><a href="delete.php?id=' .
$row['id'] . '">Borrar</a></td>';
echo '</tr>';
}?></table></div></body></html>

ACTUALIZAR DATOSCON PDO
<?php
include_once 'config.php';
$result = false;
if (!empty($_POST)) {
$id = $_POST['id'];
$newName = $_POST['name'];
$newEmail = $_POST['email'];
$sql = "UPDATE users SET name=:name,
email=:email WHERE id=:id";
$result = $query->execute([
'id' => $id,
'name' => $newName,
'email' => $newEmail
]);
$nameValue = $newName;
$emailValue = $newEmail;
} else {
$id = $_GET['id'];
$sql = "SELECT * FROM users WHERE id=:id";
$query->execute([
'id' => $id
]);
$row = $query->fetch(PDO::FETCH_ASSOC);
$nameValue = $row['name'];
$emailValue = $row['email'];
}
?>

ACTUALIZAR DATOSCON PDO
<html><head>
<title>Bases de Datos Actualizar</title></head>
<body><div class="container">
<h1>Actualizar Usuarios</h1>
<a href="list.php">Atrás</a>
<?php
if ($result) {

}?>
<form action="update.php" method="post">
