我试图将数据库的内容查看到网页中。我使用此代码：
<?php
error_reporting(0);
$host="localhost";
$username="root";
$password="";
$database="pncollege";
mysql_connect($host,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM data";
$result=mysql_query($query);
$num=mysql_numrows($result);
mysql_close();
echo "";
$i=0;
while ($i < $num) {
$email=mysql_result($result,$i,"email");
$name=mysql_result($result,$i,"name");
echo "";
$i++;
}
?>

任何人都可以帮助我并指导我在哪里犯了错误吗？我知道代码有点乱，我很抱歉。我无法弄清楚我犯了哪个错误。
答案 0 :(得分：2)
更改循环以获取每行的数组 -
while ($row = mysql_fetch_array($result)) {
$email = $row['email']; // assign this array part to a variable
$name = $row['name'];
echo $name ." " .$email . "<br />"; // echo the variables
}
// now you can close the connection, after you have used the results
mysql_close();
请stop using mysql_* functions。它们不再被维护，而是officially deprecated。请转而了解prepared statements，并考虑使用PDO it's not as hard as you think。
