Display MySQL Database as an array

Question

I have a MySQL database full of user information, like their username, password, email, etc.

我想要一个PHP脚本，该脚本允许我仅提取其用户名并显示为：

“ username1”，“ username2”，“ username3”

从字面上看完全一样，引号和所有。

编辑：很抱歉没有提供足够的信息。

该表名为“用户”，我要提取的字段是“用户名”，我可以将其提取并显示所有信息，我唯一的问题是内爆。

好家伙，请阅读评论

<?php // open a php tag

$dbc = mysql_connect("host", "username", "password"); // connect to database
mysql_select_db("db_name", $dbc) // select the database

$sql = "SELECT `username` FROM `users_table`"; // select only the username field from the table "users_table"
$result = mysql_query($sql); // process the query

$username_array = array(); // start an array

while($row = mysql_fetch_array($result)){ // cycle through each record returned
  $username_array[] = "\"".$row['username']."\""; // get the username field and add to the array above with surrounding quotes
}

$username_string = implode(",", $username_array); // implode the array to "stick together" all the usernames with a comma inbetween each

echo $username_string; // output the string to the display

?>
