我有一個多維數組，我需要查找數組是否具有相同的 'brand' 屬性值，然后返回其 id。我嘗試通過一些數組函數，但沒有奏效。我試過的：1)$backwards = array_reverse($attribute); echo '<pre>'; $last_item = NULL; $i = 0; foreach ($backwards as $current_item) { if ($last_item === $current_item[$i]['value']) { echo '<pre>'; print_r($current_item[$i]['value']); } $last_item = $current_item[$i]['value']; echo '<pre>'; print_r($last_item); $i++; }2)$j = 1; $i = 0; foreach ($attributeValues as $attributeData) { foreach ($attribute as $value) { if($value[$i]['value'] == $value[$j]['value']) { echo '<pre>'; print_r($value); die(); } $j++; } }我所有的解決方案都不起作用，請幫忙。[0] => Array ( [0] => Array ( [name] => brand [value] => 54 [id] => 5251 [price] => 15000.0000 ) [1] => Array ( [name] => model [value] => 1200 [id] => 5251 [price] => 15000.0000 ) )[1] => Array ( [0] => Array ( [name] => brand [value] => 54 [id] => 5250 [price] => 15000.0000 ) [1] => Array ( [name] => model [value] => 1200 [id] => 5250 [price] => 12000.0000 ) )[2] => Array ( [0] => Array ( [name] => brand [value] => 89 [id] => 518 [price] => 100.0000 )如果第一個數組的[name]=>brand和[name]=>model值與第二個數組的值相同，則返回[id]。

您可以使用foreach并遍歷數組
$res = [];
foreach($arr as $k => $v){
if($v[0]['name'] == $v[1]['name'])
$res[$v[0]['name']] = $v[0]['id'];
}
如果你想匹配索引value試試這個
foreach($arr as $k => $v){
if($v[0]['value'] == $v[1]['value'])
$res[] = $v[0]['id'];
}
