Thanks for reply, but I want to:
unset($ARR['a']['b'])
Imagine I have this:
$KEYS = array('a', 'b', 'c');
And I want to:
unset($ARR['a']['b']['c'])
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.
