PHP Edit Value of stdClass Object

Question

I have an array called $list that returns multiple values, I'm looping through this and displaying these values. I need to edit one of the original values.

Here's the result of;

print("<pre>".print_r($list,true)."</pre>");

Array
(
    [0] => stdClass Object
        (
            [name] => Home
            [link] => /example/
        )

    [1] => stdClass Object
        (
            [name] => Items
            [link] => /example/locations/items   <-- I want to edit this value
        )

    [2] => stdClass Object
        (
            [name] => Paris
            [link] => /example/locations/paris
        )

)

The code below;

foreach ($list as $key => $item) {
    echo $item->link;
}

Produces;

/example/
/example/locations/items
/example/locations/paris

I need to edit the link value IF the name key is Items. I essentially want to remove the last URL parameter so the output looks like this;

/example/
/example/locations
/example/locations/paris

Note that it will not always be position [1] in the array, but the name value will always be Items.

How can I achieve this?

You could use array_walk, passing it a function which checked for the name key being Items and if so returning the dirname of the link key:

array_walk($list, function (&$v) { if ($v->name == 'Items') $v->link = dirname($v->link); });

Output:

Array
(
    [0] => stdClass Object
        (
            [name] => Home
            [link] => /example/
        )    
    [1] => stdClass Object
        (
            [name] => Items
            [link] => /example/locations
        )    
    [2] => stdClass Object
        (
            [name] => Paris
            [link] => /example/locations/paris
        )    
)
