在手動將額外的列“CAD 數(shù)據(jù)”附加到帶有表格數(shù)據(jù)的多維數(shù)組后，不幸的是，我在“CAD 數(shù)據(jù)”列之前得到了這個糟糕的 [weight] 列。我的表數(shù)據(jù)輸出截圖實際上我只是想再次刪除輸出前的整個 [weight] 列。我嘗試了幾件事，但沒有成功。Array ( [row_0] => Array ( [col_0] => Order number [col_1] => Size [weight] => 1 ) [row_1] => Array ( [col_0] => 502 1001 [col_1] => 20 [weight] => 2 ) [row_2] => Array ( [col_0] => 502 1002 [col_1] => 25 [weight] => 3 ) [row_3] => Array ( [col_0] => 502 1003 [col_1] => 30 [weight] => 4 ) ) 在我的代碼下面：<?php$rows = $element['#object']->field_product_data_table['und'][0]['tabledata']['tabledata'];$header = array_shift($rows);$attributes = array( "id" => "tablefield-0", "class" => array("tablefield"));// append CAD data columnif (array_key_exists('und', $element['#object']->field_product_step_data)) { $header[] = t('CAD data'); // make index of all entries in table $entry_row_id_index = array(); foreach ($rows as $row_id => &$row) { foreach ($row as $entry) { $entry_row_id_index[$entry] = $row_id; } } $step_files = $element['#object']->field_product_step_data['und']; // add step-file to entry to rows with corresponding order number $max_row_length = 0; foreach ($step_files as &$file) { if (array_key_exists($file['description'], $entry_row_id_index)) { $orderNumber = $file['description']; $row_id = $entry_row_id_index[$orderNumber]; $rows[$row_id][] = '<a href="#" class="step-file" data-filename="' . $file['filename'] . '" data-ordernumber="' . $orderNumber . '"></a>'; $row_length = count($rows[$row_id]); if ($row_length > $max_row_length) $max_row_length = $row_length; } } // fill rows so all have same length foreach ($rows as $row_id => &$row) { for ($i = count($row); $i < $max_row_length; $i++) { $row[] = ''; } }}?>

使用數(shù)組映射。它遍歷每個元素并創(chuàng)建新的元素數(shù)組，無論你想返回什么。在您的情況下，您希望刪除 'weight' col，因此取消設(shè)置。
$array1 = [
[
'col_0' => '123',
'col_1' => '321',
'weight' => 1
],
[
'col_0' => '123',
'col_1' => '321',
'weight' => 1
],
[
'col_0' => '123',
'col_1' => '321',
'weight' => 1
],
[
'col_0' => '123',
'col_1' => '321',
'weight' => 1
],
[
'col_0' => '123',
'col_1' => '321',
'weight' => 1
],
];
$array2 = array_map(function($element) {
unset($element['weight']);
return $element;
}, $array1);

您可以使用array_map 函數(shù)操作數(shù)組
$arr = array_map(
? ? # apply function for each array element
? ? function ($el) {
? ? ? ? # return modified array elements
? ? ? ? return [
? ? ? ? ? ? 'col_0'=>$el['col_0'],?
? ? ? ? ? ? 'col_1'=>$el['col_1']
? ? ? ? ];
? ? },?
? ? $arr
);
上面的代碼使用帶有匿名函數(shù)的 array_map 從源數(shù)組接收每個元素，操作它并返回更改的元素
