获取值作为数组

Question

$sql=mysql_query("select cost from projectdetails");
while($row=mysql_fetch_assoc($sql))
{
    $data=$row['cost'];
}

这是我的PHP代码你能帮我解决这个问题，

$data = array("0" => 898, "1" => 1498, "2" => 1343,"3" => 1345, "4" => 1045, "5" => 1343, "6" => 987);

Answer 1

只需$data[] = $row['cost'];即可获得$data作为数组

Answer 2

试试这个：

$count = 0;
$sql=mysql_query("select cost from projectdetails"); 
while($row=mysql_fetch_assoc($sql))     { 
    $data[$count]=$row['cost']; 
    $count++; 
}

Answer 3

首先你应该使用PDO，它要好得多，试试这个

//edit for your server/database
$username = "username";
$password = "password";
$hostname = "hostname";
$dbname = "database-name";

//to connect to the database
$db = new PDO('mysql:host='.$hostname.';dbname='.$dbname.';charset=utf8', $username, $password);

然后查询非常简单

$query = "SELECT cost FROM projectdetails;";
$sth = $db->prepare($query);
$sth->execute();

$data = $sth->fetchAll();

现在你将所有的$ data作为数组，你可以遍历它，分配不同的值或任何你想要的。
