我將變量從數組插入到AWS DynamoDB中 $ dbf [$ a] ['variable1'],$ dbf [$ a] ['variable2'] $ dbf [$ a] ['variable3'] ...適用於PHP的AWS開發工具包DynamoDB僅適用於非空變量的PutItem
對於某些$ a,只設置'variable1'和'variable2',對其他$ a設置 ,設置所有'變量#'。
下面的代碼將不起作用,因爲空值或非設置變量不允許爲 。
是否有一種方法在循環中只嘗試爲設置的變量「PutItem」?
foreach($dbf as $day)
{
$result = $client->PutItem(array(
'TableName' => 'AWIS',
'Item' => array(
'id' => array('S' => $day['id']),
'date'=> array('S' => $day['date']),
'max'=> array('N' => $day['max']),
'min'=> array('N' => $day['min']),
'pre'=> array('N' => $day['pre']),
'max_soil_temp'=> array('N' => $day['max_soil_temp']),
'min_soil_temp'=> array('N' => $day['min_soil_temp']),
'evap'=> array('N' => $day['evap']),
'veg_wetting'=> array('N' => $day['veg_wetting']),
'solar_rad'=> array('N' => $day['solar_rad']),
'ob_temp'=> array('N' => $day['ob_temp']),
'adj_min'=> array('N' => $day['adj_min']),
'chill_hours'=> array('N' => $day['chill_hours'])
),
));
}
