基于第一个字母显示“名字”数据

我正在尝试建立一个登录表，允许用户选择他们名字的第一个字母，然后，它将从数据库中获取所有用户，并将其输出到一个可选择的列表中，该列表允许用户选择他们的姓名，然后将他们“登录”的时间戳输入到数据库中，时间戳为单击他们的姓名时的时间戳。
现在我一直在寻找让php进入表的最佳方法，查找所有以所选字母开头的“名字”，并输出名字和姓氏。
示例：我选择“p”，因为我的名字是“pietro aretino”，然后它会给出每个成员的输出，这些成员的名字以“p”开头，还包括他们的姓氏。我在列表“pietro aretino”中找到了我的名字，我选择了它，然后它会将我的登录信息存储在数据库中，我想应该是，我的名字/姓氏和时间戳。
但是，我离题了，现在，我不知道如何让php按名字进行查找，然后输出列表
现在我有每一个按钮a-z在军事字母表（阿尔法，布拉沃等）标记，当“a”被选中时，它运行下面的“阿尔法”功能。试图弄清楚在“alpha”“bravo”“charlie”等函数中放入什么，这些函数将使php进入数据库并进行查找并输出列表。
……以下是我目前掌握的情况：

<?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($_POST['alpha'])) {
    alpha();
}
if (isset($_POST['bravo'])) {
    bravo();
}
if (isset($_POST['charlie'])) {
    charlie();
}
if (isset($_POST['delta'])) {
    delta();
}
if (isset($_POST['eko'])) {
    eko();

if (isset($_POST['hotel'])) {
    hotel();
}
if (isset($_POST['india'])) {

}
if (isset($_POST['kilo'])) {
    kilo();
}
if (isset($_POST['lima'])) {
    lima();
}
if (isset($_POST['mike'])) {
    mike();
}
if (isset($_POST['november'])) {
    november();
}
if (isset($_POST['oscar'])) {
    oscar();
}
if (isset($_POST['papa'])) {
    papa();
}
if (isset($_POST['quebec'])) {
    quebec();
}
if (isset($_POST['romeo'])) {
    romeo();
}
if (isset($_POST['sierra'])) {
    sierra();
}
if (isset($_POST['tango'])) {
    tango();
}
if (isset($_POST['uniform'])) {
    uniform();
}
if (isset($_POST['victor'])) {
    victor();
}
if (isset($_POST['whiskey'])) {
    whiskey();
}
if (isset($_POST['xray'])) {
    xray();
}
if (isset($_POST['yankee'])) {

if (isset($_POST['zulu'])) {

正如人们所说的代码有点可笑。我想和大家分享一下，希望能给大家一些启示。不想回答你的问题。事实上，我建议删除这个问题，因为我不确定它能给其他人带来多少效用。而“如何进行通配符sql搜索”显然是个愚蠢的问题。
不管怎样。。。可以浓缩为：

//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？变量是什么？一封信。你是如何呈现输出的 A 不同于你将如何解释和输出 B ? 不。所以保持干燥（不要重复）。
