How to find a document by embedded item in MongoDB PHP
(1 answer)
Closed 5 years ago.
I have an ID, and I want to get all documents that has this ID in array.
How can i get all documents that:
my_ID in {recipients.ids}
I think this is something like the "opposite" to $in.
Thanks.
If I understood correctly, this should do it:
db.your_collection.find({'ids.recipients': 'the_id_you_look_for'})

This question was closed which is ok Take a look at the suggested questions. I would not have known to search what those are titled so dont just click away!.
I am not sure how to work with PHP foreach when the values it is pulling have a space in them inside the database.
Example - in the DB the following value exists and object in an array like - Number One. So I first tried:
foreach ($type as $value){
$value->Number One
};
echo $value->Number One
This above produced a string error.
I followed by using a non breaking space. Number One .
When I use this, all I get is a value of '00' which is incorrect. The value is actually '1'. So how do you handle an object in an array when there is a space in the object name as it comes from the DB?

I have this record in data base row :
a:2:
{
i:2;a:2:{s:6:"amount";d:150;s:11:"description";s:53:"value1";}
i:3;a:2:{s:6:"amount";d:1800;s:11:"description";s:53:"value 2";}
}
Is it Json or What exactly ?
And how can i extract data from it ?
I want to get each amount and description values
It's serialized data. You can use unserialize() to turn it in to an array.

I find this quite hard to explain as you can see in the title but let's say this is how my object looks like,
{
"success":true,
"objects":[
{
"name":"Stick",
"value":"wood",
"size":"large"
}...
]
}
Now I'm trying to get all the data where the objects name is Stick, so basically if it's "name" is stick it should return, name, value and size.
