PHP现有下面的数组，
$data = array (
array (
'entity_id' => '880',
'sku' => '100088',
'name' => 'Tablet PC 512MB RAM 8GB Memory Wi-Fi Camera(Black)',
'price' => '117.8300',
'item' => array (
array (
'attribute_id' => '103',
'frontend_label' => 'Meta Title',
'value' => NULL,
),
array (
'attribute_id' => '972',
'frontend_label' => 'Features',
'value' => '131,201,129',
),
array (
'attribute_id' => '992',
'frontend_label' => 'Battery capacity',
'value' => '5500mAh',
),
),
),
)
怎样修改attribute_id = 972的value值呢，把131,201,129换成其它的值。谢谢！

foreach($data as &$item){ foreach($item['item'] as &$v){ if($v['frontend_label']== 'Features') $v['value'] = '123,123,123'; } }foreach($data as &$item){ foreach($item['item'] as &$v){ if($v['frontend_label']== 'Features') $v['value'] = '123,123,123'; } }foreach ($data['item'] as $k => $v){
if($v['attribute_id'] == 972){
$data['item'][$k]['value'] = '131,201,129';
}
}
若数组确定： $data['item'][2]['value']='131,201,129'; 若数组不确定： foreach($data['item'] as $k=>$v){ if($v['attribute_id'] == '972'){ $data['item'][$k]['value']='131,201,129'; } }引用来自“祺爸PiscDong”的答案
