数组与对象相互转化

本文实例讲述了php对象和数组相互转换的方法。分享给大家供大家参考。具体分析如下：

这里定义2个php匿名对象和数组相互转换的函数，代码如下：

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

对象转化为数组
$conn=mysqli_connect('localhost','root','','cf');
$sql="select * from dis where id=81";
$rs=mysqli_query($conn,$sql);
$s=$rs->num_rows;
var_dump($rs);
echo '<br><br>';
echo $s;
echo '<br><br>';
function object_to_array($obj) {
$obj = (array)$obj;
foreach ($obj as $k => $v) {
if (gettype($v) == 'resource') {
return;
}
if (gettype($v) == 'object' || gettype($v) == 'array') {
$obj[$k] = (array)object_to_array($v);
}
}

return $obj;
}

$array=object_to_array($rs);
var_dump($array);
echo '<br><br>';

$conn=mysql_connect('localhost','root','');
mysql_query('set names utf8');
mysql_query('use cf');
$rs=mysql_query('select count(*) from dis where id=81',$conn);
var_dump($rs);
