How to search objects to see if they contain a specific value?

Question

I have various objects that look like this:

Array
(
[0] => stdClass Object
    (
        [tid] => 18
        [vid] => 1
        [name] => test
        [description] => 
        [format] => 
        [weight] => 0
        [depth] => 0
        [parents] => Array
            (
                [0] => 0
            )

    )

[1] => stdClass Object
    (
        [tid] => 21
        [vid] => 1
        [name] => tag
        [description] => 
        [format] => 
        [weight] => 0
        [depth] => 0
        [parents] => Array
            (
                [0] => 0
            )

    )
)

Basically I need to find out weather a [name] value exists in these objects, how do I go about doing this?

Solution

To check if the name property exists in an object:

if(isset($obj->name)) {
    // It exists!
}

So, if you want to find those objects that had $name properties:

$result = array_filter($myArray, function($x) {
    return isset($x->name);
}); // Assuming PHP 5.3 or higher

Thanks. But it's the actual value I need. I have tried various things such as counting the array items and then using a for loop to check weather each name property of each object equals my value. This I think is working at the moment but if there are a lot of objects, could this get quite slow?

@Robert: That would depend on how many objects you have, but there's really no faster way to search through an unsorted list.

Is it possible to check multiple properties at a time, instead of using isset() for every property ?

@dskanth: You can pass multiple variables to isset, and it’s the same of anding them all together.
