maybe something like this if you are willing to get rid of your weird array
dimension delimiters (you can use a dot for that for example, see below)
$a = array(
"a" => array(
"b" => array(
"c" => array(
"d" => array(
"e" => array(
"f" => 1
)
)
)
)
)
);
function coolFunction( array $array, $search, $separator = '.' )
{
if ( empty( $array ) ) {
return false;
}
if ( strlen( $search ) === 0 ) {
return false;
}
$dimensions = explode( $separator, $search, 2 );
$dimension = array_shift( $dimensions );
if ( isset( $array[$dimension] ) ) {
// no more dimensions to search
if ( empty( $dimensions ) ) {
return $array[$dimension];
}
// more dimensions to search but we can only go further if
// the current dimension value is also an array
if ( is_array( $array[$dimension] ) ) {
return coolFunction( $array[$dimension], $dimensions[0] );
} else {
return false;
}
} else {
return false;
}
}
var_dump( coolFunction( $a, "a.b" ) );
var_dump( coolFunction( $a, "a.b.d.e.c" ) );
var_dump( coolFunction( $a, "a.b.c.d.e.f" ) );
var_dump( coolFunction( $a, "a.b.c.d.e.f.g" ) );
