MySQL的。随机行。将行转换为PHP数组。

Question

我有一个包含四列的MySQL表submited_name, submited_URL, submited_type, uniqueID。在这张表中我有大约1000条记录。我需要选择10个随机条目。问题是我需要将选定的随机值拆分为单独的PHP数组。每列一个。我的数组应该是这样的：

$ten_random_names = array ('name26', 'name55', 'name107', ect.);
$ten_random_URL = array ('url for name26', 'url for name55', 'url for name107', ect..);
$ten_random_types = array ('type for name26', 'type for name55', 'type for name107', ect..);

Answer 1

基础知识：

$sql = "SELECT name, url, type FROM ... WHERE ... ORDER BY random() LIMIT 10"; // inefficient, but works
$results = mysql_query($sql) or die(mysql_error());

$names = $url = $types = array();
while($row = mysql_fetch_assoc($results)) {
   $names[] = $row['name'];
   $url[] = $row['url'];
   $type[] = $row['type'];
}

Answer 2

$query = "SELECT *
          FROM tablename
          ORDER BY RAND()
          LIMIT 10";
$result = mysql_query($query);

$ten_random_names = $ten_random_URL = $ten_random_types = array();
while ($row = mysql_fetch_assoc($result)) {
  $ten_random_names[] = $row['submited_name'];
  $ten_random_URL[] = $row['submited_URL'];
  $ten_random_types[] = $row['submited_type'];
}
