Removing selected elements from array of associative arrays

Question

I have the following array of associative arrays.

$result = array(
    (int) 0 => array(
        'name' => 'Luke',
        'id_number' => '1111',
        'address' => '1544addr',
        'time_here' => '2014-04-12 13:07:08'
    ),
    (int) 1 => array(
        'name' => 'Sam',
        'id_number' => '2222',
        'address' => '1584addr',
        'time_here' => '2014-04-12 14:15:26'

I want to remove selected elements from this array such that it will look like this;

array(
    (int) 0 => array(
        'name' => 'Luke',
        'id_number' => '1111'
    ),
    (int) 1 => array(
        'name' => 'Sam',
        'id_number' => '2222',

This is the code I wrote;

    foreach($result as $value) 
    {            
        unset($value('address')  );
        unset($value('time_here')  );
    }

When I run the code, Apache web server crashed.

Can the smarter members point out what did I do wrong? Thank you very much.

Your array notation is wrong. You need to use [] See my answer — Hüseyin BABAL

Array notation is wrong, use this;

$finalResult = array();
foreach($result as $value) 
{            
    unset($value['address']  );
    unset($value['time_here']  );
    $finalResult[] = $value;
}

Here is a working demo: Demo

Thanks! I have one more problem. How do I store the truncated array to $result? The answer removes the element from $value, not $result.

I have a follow-up question. stackoverflow.com/questions/23235855/… This time, I would like to filter selected elements and not remove them. This is more tricky. I don't even know what function to start with. At least, for removal, one can use unset(). Would you be able to help?

That is because you are not accessing array correctly. Use square bracket insted of round brackets :

foreach($result as $value) 
    {            
        unset($value['address']  );
        unset($value['time_here']  );
    }

It would be better, check already answered ones before posting your answer
