按字母顺序列出数组值并带有字母标题

发布于 2024-12-10 18:15:29 字数 883 浏览 0 评论 0原文

我需要一些帮助来解决这个问题。我正在尝试创建一个函数，该函数按字母顺序输出数组中的值，但在到达当前字母的末尾后也会回显新的字母标题。例如：

A

亚马逊

美国

B

巴哈马

百慕大

C

加拿大

柬埔寨

等。

到目前为止，我可以通过重复“$result”中的代码来做到这一点，但我知道这不是一个好的做法，所以我正在寻找包含变量的东西而不是“a%”，并在每次成功运行脚本后自动递增该字母（在 Z 处停止）。

<?php
$username = "myusername";
$password = "mypsswrd";
$hostname = "localhost"; 


$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");


$selected = mysql_select_db("mydb",$dbhandle)
or die("Could not select database");

$result = mysql_query("SELECT user, name FROM users WHERE name like 'a%' ORDER BY name");
echo "A<br />";
while ($row = mysql_fetch_array($result)) {
echo "<a href=\"/artists/artist.php?user=".$row{'user'}."\">".$row{'name'}."</a><br />";
}
echo "<br />";

I need some help figuring this out. I am trying to create a function that outputs values in an array alphabetically, but also echoes a new letter title after it reaches the end of the current letter. Ex:

A

Amazon

America

B

Bahamas

Bermuda

C

Canada

Cambodia

Etc.

I can do it by repeating the code from "$result" on so far, but I understand it's just not good practice, so I'm looking for something that includes a variable instead of the "a%", and autoincrements the letter (stopping at Z), after each successful run of the script.

<?php
$username = "myusername";
$password = "mypsswrd";
$hostname = "localhost"; 


$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");


$selected = mysql_select_db("mydb",$dbhandle)
or die("Could not select database");

$result = mysql_query("SELECT user, name FROM users WHERE name like 'a%' ORDER BY name");
echo "A<br />";
while ($row = mysql_fetch_array($result)) {
echo "<a href=\"/artists/artist.php?user=".$row{'user'}."\">".$row{'name'}."</a><br />";
}
echo "<br />";

$result = mysql_query("SELECT user, name FROM users ORDER BY name");
$last = '';

while ($row = mysql_fetch_array($result)) {
    $current = strtolower($row['name'][0]);
    if ($last != $current) {
        echo strtoupper($current) . "<br />";
        $last = $current;
    }
    echo "<a href=\"/artists/artist.php?user=".$row{'user'}."\">".$row{'name'}."</a><br />";
}

$result = mysql_query("SELECT user, name FROM users ORDER BY name");
$last = '';

while ($row = mysql_fetch_array($result)) {
    $current = strtolower($row['name'][0]);
    if ($last != $current) {
        echo strtoupper($current) . "<br />";
        $last = $current;
    }
    echo "<a href=\"/artists/artist.php?user=".$row{'user'}."\">".$row{'name'}."</a><br />";
}
