Mongo DB $or query in PHP
提问by Andrew
I can't figure out for the life of my to select from a collection with the orparameter. It's not working at all for me and I can't really find any documentation on it for php.
我一生都无法从带有or参数的集合中进行选择。它对我来说根本不起作用，我真的找不到任何关于 php 的文档。
Here is my example code that doesn't return anything even though they exist in the collection:
这是我的示例代码，即使它们存在于集合中，也不返回任何内容：
$cursor = $products->find(
array(
'$or' => array(
"brand" => "anti-clothes",
"allSizes" => "small"
)
)
);

The $or operator lets you use boolean or in a query.
You give $or an array of expressions, any of which can satisfy the query.
You provided only one element in the array. Use:
您只提供了数组中的一个元素。用：
find(array('$or' => array(
array("brand" => "anti-clothes"),
array("allSizes" => "small")
)));
