Re: [PHP] Array references - how to unset() ?

[Martin Zvarík]

AHA !!!

OMG... how come I did not see that!?

Instead this:
$array =& $array[$final];
unset($array);

This:
unset($array[$final]);


3 AM in the morning... that must be the reason! .)

Thanks.

This is possible. You're just not giving enough consideration to your exit strategy :)

<?php

function unset_deep( &$array, $keys )
{
    $final = array_pop( $keys );

    foreach( $keys as $key )
    {
        $array = &$array[$key];
    }

    unset( $array[$final] );
}

$value = array
(
    'a' => array
    (
        'b' => array
        (
            'c' => 'C',
            'd' => 'D',
            'e' => 'E'
        ),
    ),
);

$keys = array('a', 'b', 'c');
unset_deep( $value, $keys );

print_r( $value );

?>

Cheers,
Rob.
