Answer 1

我认为问题出在你的$ result函数中它应该有2个参数而你只给了一个所以你的代码应该是这样的

<?php
$connection=mysqli_connect('localhost','yourmysqlusername','yourmysqlpassword','yourmysqldatabase');
     $sql="SELECT (file,user_name,user_id,user_occupation) FROM users1";
    //you have to add $connection as 2nd parameter in $result function
        $result_set=mysql_query($connection,$sql) or die(mysql_error());
            while($row=mysql_fetch_object($result_set))
?>

Answer 2

确保首先使用mysql_select连接到数据库，然后使用mysql_select_db选择数据库。在此之后，您需要使用mysql_query启动查询。

此外，您可以mysqli_connect组合前两个步骤。见this
