如何在数组中存储mysql数据的行/列

I want to be able to store (not echo) some data that has been selected from a mysql database in a php array. So far, I have only been able to echo the information, I just want to be able to store it in an array for later use. Here is my code:

我希望能够存储（不回显）从php数组中的mysql数据库中选择的一些数据。到目前为止，我只能回应信息，我只是希望能够将它存储在一个数组*以后使用。这是我的代码：

$query = "SELECT interests FROM signup WHERE username = '$username'";
$result = mysql_query($query) or die ("no query");
while($row = mysql_fetch_array($result))
{
echo $row['interests'];
echo "<br />";
}

You could use

你可以用

$query = "SELECT interests FROM signup WHERE username = '".mysql_real_escape_string($username)."'";
$result = mysql_query($query) or die ("no query");

$result_array = array();
while($row = mysql_fetch_assoc($result))
{
    $result_array[] = $row;
}

This will basically store all of the data to the $result_array array.

这基本上将所有数据存储到$ result_array数组中。

I've used mysql_fetch_assoc rather than mysql_fetch_array so that the values are mapped to their keys.

我使用了mysql_fetch_assoc而不是mysql_fetch_array，以便将值映射到它们的键。

I've also included mysql_real_escape_string for protection.

我还包括mysql_real_escape_string以进行保护。

You can "store" it by not accessing it from the result set until you need it, but if you really want to just take it and put it in a variable…

您可以通过不在结果集中访问它来“存储”它，直到您需要它为止，但是如果您真的想要把它放在一个变量中......

$query = "SELECT interests FROM signup WHERE username = '$username'";
$result = mysql_query($query) or die ("no query");

$interests = array();
while(false !== ($row = mysql_fetch_assoc($result))) {
  $interests[] = $row;
}
