Question

我正在尝试构建一个允许用户选择其名字的第一个字母的登录表，然后它将从数据库中获取所有用户并将其输出到可选择列表中，然后允许用户选择他们的名字，然后输入他们“登录”到数据库的时间，并带有他们点击他们名字的时间戳。

现在，我一直停留在使PHP进入表中的最佳方法上，并查找所有以所选字母开头的“名字”，并输出First_Name和Last_Name。 / p>

示例：我选择“ P”，因为我的名字是“ Pietro Aretino”，然后它给我其First_Name以“ P”开头并包括其姓氏的每个成员的输出。我在“ Pietro Aretino”列表中找到了我的名字，选择了它，然后它还将我的登录信息也存储在数据库中，我的名字/姓氏和时间戳也将存储在该数据库中。

但是，我离题了，目前，我不确定如何让PHP按名字进行查找，然后输出列表

现在，我的每个按钮A-Z都标有军事字母（字母，Bravo等），当选择“ A”时，它将在下方向下运行“字母”功能。试图弄清楚将什么放入“ alpha”，“ bravo”，“ charlie”等函数中，这些函数将使PHP进入数据库并进行查找并输出列表。

...这是我到目前为止所拥有的：

<?php
$servername = "localhost";
$username = "*********";
$password = "*********";
$dbname = "********** ";

//Create Connection
global $CONNECTION;
$CONNECTION = new mysqli($servername, $username, $password, $dbname);
//Check Connection
if ($CONNECTION->connect_error) {
    die("Connection To MySQL Database Failed With the Following Error: " . $connection->connect_error);
}
global $SQL; 
$SQL = "SELECT first_name, last_name FROM ppSD_member_data";
global $RESULT; 
$RESULT = $CONNECTION->query($SQL);
if (isset($_POST['alpha'])) {
    alpha();
}

    bravo();

正如人们所说的那样，代码有点荒谬。我只是想分享一下，希望能教给您一些东西。并不是真的想回答您的问题。实际上，我建议只是删除问题，因为我不确定它可以为他人提供多少实用程序。而且“如何进行通配符SQL搜索”显然是一个重复的问题。

无论如何...可能会浓缩为：

//example.com?search_letter=A

$pattern = isset($_REQUEST('search_letter')) ? $_REQUEST('search_letter') : null;

if (empty($pattern)) {
    die('missing search paramter');
}

$pattern = $pattern . '%';
$sql = 'SELECT * FROM users WHERE first_name LIKE ?';

$sth->execute([$pattern]);
$results = $sth->fetchAll();

有什么变化？什么是变量？一封信。您呈现A的输出的方式与解释和输出B的方式是否有所不同？不，所以请保持干燥（不要重复自己）。
