我正在使用 SQL 檢索表單數據并使用 PHP 顯示它。這些字段顯示為qualification_0和qualification_type_0，唯一改變的值是數字，所以我想將這些值分組到一個數組中，然后我可以將其顯示到正確的輸入中。用戶可以刪除輸入，因此數字不會總是遞增 1，但總是成對發送?，F在數據顯示為：Array( [qualification_0] => Karate [qualification_2] => Test [qualification_type_0] => Course [qualification_type_2] => Certificate)目標我正在努力實現以下目標：Array( [0] => Array ( [qualification_0] => Karate [qualification_type_0] => Course ) [1] => Array ( [qualification_2] => Test [qualification_type_2] => Certificate ))我的代碼數據庫/PHP： public function getAllSelfDevelopments() { global $wpdb; $table_name = $wpdb->prefix . "usermeta"; $result = $wpdb->get_results( " SELECT meta_key, meta_value FROM $table_name WHERE user_id = $this->user_id AND meta_key LIKE 'qualification%' ", ARRAY_A ); return $result; }查詢結果：Array( [0] => Array ( [meta_key] => qualification_0 [meta_value] => Karate ) [1] => Array ( [meta_key] => qualification_2 [meta_value] => Test ) [2] => Array ( [meta_key] => qualification_type_0 [meta_value] => Course ) [3] => Array ( [meta_key] => qualification_type_2 [meta_value] => Certificate ))試圖： $self_developments = $candidate->getAllSelfDevelopments(); $self_developments_arr = []; foreach($self_developments as $value){ $self_developments_arr[$value['meta_key']] = $value['meta_value']; } $self_dev = []; foreach($self_developments_arr as $key => $value){ if(strpos($key, $key[-1]) !== FALSE && !in_array($key, $self_dev)){ $self_dev[] = [ $key => $value ]; } }任何幫助將不勝感激。

這應該可以幫助您實現目標。它涉及正則表達式的一些高級用法。
//Load in meta data
$self_developments = $candidate->getAllSelfDevelopments();
//Create container for results
$results = [];
foreach($meta_values as $meta) {
//Create Named matching groups that go into $matches. See PHP docs for details.
preg_match('/(?P<key>.+)_(?P<index>\d+)/',$meta['meta_key'], $matches);
//Use our index value to act as a guide to place our data. If the index does not exist, make it an empty array.
//Otherwise, merge in our existing data with the new data.
$results[$matches['index']] = array_merge($results[$matches['index']] ?? [], [$meta['meta_key'] => $meta['meta_value']]);
}
//if you want to re-index the array.
$results = array_values($results);
應該輸出：
Array
(
[0] => Array
(
[qualification_0] => Karate
[qualification_type_0] => Course
)
[2] => Array
(
[qualification_2] => Test
[qualification_type_2] => Certificate
)
)
或者，如果您選擇重新編制索引：
Array
(
[0] => Array
(
[qualification_0] => Karate
[qualification_type_0] => Course
)
[1] => Array
(
[qualification_2] => Test
[qualification_type_2] => Certificate
)
)

這個解決方案可以解決嗎？
$array = [
'qualification_0' => 'Karate',
'qualification_2' => 'Test',
'qualification_type_0' => 'Course',
'qualification_type_2' => 'Certificate',
];
foreach ($array as $key => $value) {
preg_match('~(.+)_(\d+)~', $key, $match);
${$match[1]}[$match[2]] = $value;
}
$result = array_combine($qualification, $qualification_type);
print_r($result);
它會輸出：
Array
(
[Karate] => Course
[Test] => Certificate
)
