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

Conversion of php multi-layer arrays and objects
The purpose of conversion of multi-layer arrays and objects is very simple. Convenient to handle the conversion of multi-layer arrays and objects in WebService
Simple (array) and (object) can only handle single-layer data, but cannot do anything about multi-layer array and object conversion.
The object can be converted into an array at one time through json_decode(json_encode($object), but there will be problems when encountering non-utf-8 encoded non-ascii characters in the object, such as gbk Chinese, not to mention the performance of json_encode and decode It is also worth doubting

The code below:

Copy the code The code is as follows:

 

function objectToArray($d) { 
if (is_object($d)) { 
// Gets the properties of the given object 
// with get_object_vars function 
$d = get_object_vars($d); 
} 

if (is_array($d)) { 
/* 
* Return array converted to object 
* Using __FUNCTION__ (Magic constant) 
* for recursive call 
*/ 
return array_map(__FUNCTION__, $d); 
} 
else { 
// Return array 
return $d; 
 } 
} 

function arrayToObject($d) { 
if (is_array($d)) { 
/* 
* Return array converted to object 
* Using __FUNCTION__ (Magic constant) 
* for recursive call 
*/ 
return (object) array_map(__FUNCTION__, $d); 
} 
else { 
// Return object 
 return $d; 
} 
} 

// Useage: 
// Create new stdClass Object 
$init = new stdClass; 
// Add some test data 
$init->foo = "Test data"; 
$init->bar = new stdClass; 
$init->bar->baaz = "Testing"; 
$init ->bar->fooz = new stdClass; 
$init->bar->fooz->baz = "Testing again"; 
$init->foox = "Just test"; 

// Convert array to object and then object back to array 
$array = objectToArray($init); 
$object = arrayToObject($array); 

// Print objects and array 
print_r($init); 
echo "n"; 
print_r($array); 
echo "n"; 
print_r($object); 
 ?>
