删除变量内的数组

Question

In my content management system, the variable $data outputs the following:

Array ( [name] => last_visit [value] => 1211809129 [expire] => 1558705129 [domain] => [path] => / [prefix] => exp_ [httponly] => 1 [secure_cookie] => 0 ) 
Array ( [name] => last_activity [value] => 1527169129 [expire] => 1558705129 [domain] => [path] => / [prefix] => exp_ [httponly] => 1 [secure_cookie] => 0 ) 
Array ( [name] => csrf_token [value] => e39fe1edcd0bc48a6e35985069a [expire] => 1527176329 [domain] => [path] => / [prefix] => exp_ [httponly] => 1 [secure_cookie] => 0 ) 

I need to modify the variable, removing an array, for example the second array with the 'name' of 'last_activity'.

As the arrays don't have keys, I am having trouble selecting it to delete it.

I had thought I could use unset, like:

unset($data[1]);

but this doesn't work.

How can I remove an array from the variable?

Answer 1

you could do it like this:

foreach ($data as $key => $value)
{
    if ($value['name'] === 'last_activity') {
        unset($data[$key]);
    }
}
