php简单对象与数组的转换

最近用到一些简单的对象与数组的相互转换的问题，采用递归写了两个方法如下

function arrayToObject($e){
if( gettype($e)!='array' ) return;
foreach($e as $k=>$v){
if( gettype($v)=='array' || getType($v)=='object' )
$e[$k]=(object)arrayToObject($v);
}
return (object)$e;
}

function objectToArray($e){
$e=(array)$e;
foreach($e as $k=>$v){
if( gettype($v)=='resource' ) return;
if( gettype($v)=='object' || gettype($v)=='array' )
$e[$k]=(array)objectToArray($v);
}
return $e;
}
