            [bill_details] => 19.90
            [st_id] => 0
            [user_id] => 0

Answer 1

foreach ($array as $key => $value){
     echo "Key is $key and value is $value";
}

或

echo $array[0]['id'];

然后你可以获得key的当前值。谢谢

Answer 2

当您在数组内部使用数组时，您可以使用foreach中的foreach获取每个值，如

<?php
$bill_details[] = array("id" => 355, "bill_details" => 19.90, "st_id" => 0, "user_id" => 0,"status" => 0);
print_r($bill_details);

foreach($bill_details as $key => $value){
    foreach($value as $vala){
        echo $vala;
    }
}
?>
