如何使用循环从数据库结果集中创建PHP中的以下数组:
Array
(
[T] => Array
(
[0] => Array
(
[id] => 1
[name] => Timer
)
[1] => Array
(
[id] => 2
[name] => Tub
)
)
[P] => Array
(
[0] => Array
(
[id] => 3
[name] => Paper
)
[1] => Array
(
[id] => 4
[name] => Puppy
)
)
)
您会注意到数组键是一个字母,它取自结果集中的“name”值。循环将是这样的:
while($result = $db->fetch($query) {
$key = $result['name']{0};
// your answer :-)
}

我觉得这样的事情应该这样做:
$sql = 'SELECT id, name FROM table';
$result = mysql_query( $sql);
$answer = array();
while( $row = mysql_fetch_assoc( $result))
{
$answer[ strtoupper($row['name'][0]) ][] = $row;
}
mysql_free_result( $result);
var_dump( $answer);
OR,更具体一点(如果您的查询返回的列数不仅仅是id
和name
):
while( $row = mysql_fetch_assoc( $result))
{
$answer[ strtoupper($row['name'][0]) ][] = array(
'id' => $row['id'],
'name' => $row['name']
);
}

$indexArray = array(); // Array from Example
while($result = $db->fetch($query) {
$key = $result['name']{0};
if(!isset($indexArray[$key])) {
$indexArray[$key] = array();
}
array_push($indexArray[$key], $result);
}

$results = array();
while($result = $db->fetch($query)) {
$key = strtoupper($result['name'][0]);
if(!isset($results[$key]))
$results[$key] = array();
$results[$key][] = $result;
}
