Question

我只需要这些PHP专家的帮助。我对PHP有一点了解。我收到了此代码的PHP Fatal error: Unsupported operand types：

$ticket_item_types += array(
    val_paperworkticket => 19,
    val_disposal => 9,
    comment => 22,
    loadtime => 20,
    bbls => 23,
    disposalticketno => 46,
    load_reviewed => 31
);

Answer 1

如果键是变量，则必须在变量名之前使用$，因此它必须是：

$ticket_item_types += array(
    $val_paperworkticket => 19,
    $val_disposal => 9,
    $comment => 22,
    $loadtime => 20,
    $bbls => 23, 
    $disposalticketno => 46,
    $load_reviewed => 31
);

如果它们是字符串，则必须引用它们：

$ticket_item_types += array(
    'val_paperworkticket' => 19,
    'val_disposal' => 9,
    'comment' => 22,
    'loadtime' => 20,
    'bbls' => 23,
    'disposalticketno' => 46,
    'load_reviewed' => 31

）;

另外，请考虑带有数组的+运算符不能理解为sum运算符，而是Union运算符

+运算符返回附加到左侧数组的右侧数组;对于存在于两个数组中的键，将使用左侧数组中的元素，并且将忽略右侧数组中的匹配元素。

Answer 2

您的问题来自您的操作+ =。

如果$ ticket_item_types是一个数组，你应该使用array_push。

否则，

$ ticket_item_types = array（val_paperworkticket =＆gt; 19，val_disposal =＆gt; 9，comment =＆gt; 22，loadtime =＆gt; 20，bbls =＆gt; 23，disposalticketno =＆gt; 46，load_reviewed =＆gt; 31） ;

应该删除问题。
