简单的PDO连接和选择

Posted 2021-02-23

This is the basic code that you need to know to connect and list data with PDO.
Don't use de old method (mysql_connect and mysqli_connect) to connect and interact with databases.

<?php
/* Connection string */
$db = new PDO('mysql:host=localhost;dbname=YOUR_DB_NAME', 'root', 'YOUR_DB_PASSWORD', array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
 
$stmt = $db->prepare('select * from your_table');
$stmt->execute();
 
// Get all records
$result = $stmt->fetchAll();
 
echo '<pre>';
print_r($result); // Show a data array with results
