PHP在数组的关联数组中转换数组数组

I read a csv file and got this array $rows

Array
(
 [0] => Array
     (
        [0] => Name
        [1] => Company
        [2] => Email
        [3] => City
    )
[1] => Array
    (
        [0] => Foo
        [1] => Foo & co
        [2] => foo@mail.com
        [3] => NY
    )
[2] => Array
    (
        [0] => Bar
        [1] => Bar & co
        [2] => bar@mail.com
        [3] => Las Vegas
    )
)

I would try to transform it into an associative array by filtering only some fields contained in the first array. The result should be this

Array
(
[0] => Array
   (
    ['Name'] => Foo
    ['Company'] => Foo & co
    ['Email] => foo@mail.com
   )
 [1] => Array
 (
    ['Name'] => Bar
    ['Company'] => Bar & co
    ['Email] => bar@mail.com
 )
)

Unfortunately I tried it in various ways but without success.

$name = array_search('Name', $rows[0]);
$company = array_search('Company', $rows[0]);
$email = array_search('Email', $rows[0]);

$rows = unset($rows[0]);

$array = array();

foreach ( $rows as $r => $row ) {
    foreach ( $row as $c => $cell ) {

    if ($c == $name) { $array = array( 'name' => $cell ); }
    if ($c == $company) { $array = array( 'company' => $cell ); }
    if ($c == $email) { $array = array( 'email' => $cell ); }
    }

}

Can you give me some suggestions? Thank you
