我想要得到的是删除 Rest 字段中的重复值,但我想分配/保留其原始日期。元素:
array (size=413)
0 =>
array (size=5)
'Date' =>
array (size=1)
0 => int 1588520980
'Rest' => 123abc
1 =>
array (size=5)
'Date' =>
array (size=1)
0 => int 1588520981
'Rest' => qwe123
2 =>
array (size=5)
'Date' =>
array (size=1)
0 => int 1588520983
'Rest' => qwe123
我试过了,但没用
public function find_repeats($arr)
{
foreach(array_column($arr, 'Rest') as $ckey=>$value) {
$keys = array_reverse(array_keys(array_column($arr, 'Rest'), $value));
foreach ($keys as $v) {
if ($ckey != $v && isset($arr[$v]))
{
$arr[$ckey]['Date'][] = $arr[$v]['Date'][0];
unset($arr[$v]);
}
}
}
return $arr;
}
这是此操作后表格的外观
array (size=413)
0 =>
array (size=5)
'Date' =>
array (size=1)
0 => int 1588520980
'Rest' => 123abc
1 =>
array (size=5)
'Date' =>
array (size=1)
0 => int 1588520981
1 => int 1588520983
'Rest' => qwe123
感谢帮助!:)
