对象数组互相转换

function array2object( $array ) {
  if ( is_array ( $array )) {
    $obj = new StdClass();
    foreach ( $array as $key => $val ){
      $obj -> $key = $val ;
    }
  }
  else { $obj = $array ; }
  return $obj ;
}
function object2array( $object ) {
  if ( is_object ( $object )) {
    foreach ( $object as $key => $value ) {
      $array [ $key ] = $value ;
    }
  }
  else {
    $array = $object ;
  }
  return $array ;
}

用法示例如下：

$array = array ( 'foo' => 'bar' , 'one' => 'two' , 'three' => 'four' );
$obj = array2object( $array );
print $obj ->one; // output's "two"
$arr = object2array( $obj );
print $arr [ 'foo' ]; // output's bar
