读取数据库记录，存储在数组的问题

[石头子]

$sql="select name,city,age from usertables";
$query = mysql_query($sql,$dbconn);
$record = mysql_fetch_array($query);

怎么像while($row=mysql_fetch_array($query)){

}这样列出record的数据哪？

$record数组的结构是怎样的？

$sql="select name,city,age from usertables";
$query = mysql_query($sql,$dbconn);
$record = mysql_fetch_array($query);

print_r($record);

[chinaworker]

$sql="select name,city,age from usertables";
$query = mysql_query($sql,$dbconn);

while($row=mysql_fetch_array($query)){
print_r($row);
}

[countstars]

$sql="select name,city,age from usertables";
$query = mysql_query($sql,$dbconn);
while($record = mysql_fetch_array($query))
{
$值 = $record['字段名'];
// ....
}

[feel8]

print_r($record)

$sql="select name,city,age from usertables";
$query = mysql_query($sql,$dbconn);
while($record = mysql_fetch_array($query))
{
$值 = $record['字段名'];
....
}


想看他的结构就print_r($record);
