This is a multidimensional recursive find function :
<?php
function GetArrKey( $findArr, $key_arr, $depth=0 )
{
if( count($key_arr) <= $depth || !array_key_exists($key_arr[$depth], $findArr) )
return NULL;
else if( count($key_arr) == $depth+1 )
return $findArr[$key_arr[$depth]];
return self::GetArrKey( $findArr[$key_arr[$depth]], $key_arr, $depth+1 );
}
?>
Using :
<?php
$findArray = array( "first_dim" => array( "first_dim_in_1" =>
array( "first_dim_in_1_val_1", "first_dim_in_1_val_2",
"first_dim_in_1_val_3" ), "first_dim_in_2" => array(
"first_dim_in_2_val_1", "first_dim_in_2_val_2", "first_dim_in_2_val_3"
) ), "second_dim" => array( "second_dim_in" => "test",
"second_dim_in_val_1"));
var_dump( GetArrKey( $findArray, array( "first_dim", "first_dim_in_2" )
) );
/*
Prints :
array( "first_dim_in_2_val_1", "first_dim_in_2_val_2",
"first_dim_in_2_val_3" )
*/
//----------------------------------------------------//
var_dump(GetArrKey( $findArray, array( "first_dim", "first_dim_in_2", 0
) ) );
/*
Prints :
string(20) => "first_dim_in_2_val_1"
*/
//----------------------------------------------------//
var_dump(GetArrKey( $findArray, array( "second_dim", 0 ) ) );
/*
Prints :
string(4) => "test"
*/
//----------------------------------------------------//
var_dump(GetArrKey( $findArray, array( "second_dim", 0 ) ) );
/*
Prints :
string(4) => "test"
*/
//----------------------------------------------------//
var_dump(GetArrKey( $findArray, array( "second_dim", 1 ) ) );
/*
Prints :
string(19) => "second_dim_in_val_1"
*/
//----------------------------------------------------//
var_dump(GetArrKey( $findArray, array( "second_dim", 1, 1 ) ) );
/*
Prints :
std_object => NULL
*/
?>
