如果 money 确实是 VARCHAR 中的数字,则可以使用 cast。
试试这个:
concat_ws(pl.last_name,'-',cast(money AS unsigned)); // This is with decimals.
concat(`pl.last_name,'-',substring_index(money,',',1)) // Without decimals. If you use . i.e. the American currency notation you can substitute , with an .

您应该首先尝试 concat(pl.last_name,'-',format(money,0))
:
这是您可以使用的非常基本的 php 代码。
<?php
function selecting_data(){
$host = "host";
$user = "username";
$password = "password";
$database = "database";
$charset = "utf8";
$link = mysqli_connect($host, $user, $password, $database);
mysqli_set_charset($charset, $link);
IF (!$link) {
echo('Unable to connect to the database!');
} ELSE {
$query = "SELECT lastname, format(money,0) FROM mytable"; //Select query
$result = mysqli_query($link, $query);
while ($rows = mysqli_fetch_array($result, MYSQLI_BOTH)){
echo $rows['lastname']."<br>".$rows['money'] ;
}
}
mysqli_close($link);
}
