PHP：如何将数组转换为StdClass对象？

Question

Is there a PHP function that will do this automatically?

if (is_array($array)) {
    $obj = new StdClass();
    foreach ($array as $key => $val){
        $obj->$key = $val;
    }
    $array = $obj;
}

Answer 1

Why not just cast it?

$myObj = (object) array("name" => "Jonathan");
print $myObj->name; // Jonathan

If it's multidimensional, Richard Castera provides the following solution on his blog :

function arrayToObject($array) {
  if(!is_array($array)) {
    return $array;
  }
  $object = new stdClass();
    if (is_array($array) && count($array) > 0) {
      foreach ($array as $name=>$value) {
        $name = strtolower(trim($name));
          if (!empty($name)) {
            $object->$name = arrayToObject($value);
          }
      }
      return $object; 
    } else {
      return FALSE;
    }
}

Answer 2

如果它是一维数组，则应该使用强制转换：

$obj = (object)$array;

Answer 3

This works for me

if (is_array($array)) {
$obj = new StdClass();
foreach ($array as $key => $val){

    $key = str_replace("-","_",$key) 

    $obj->$key = $val;
}
$array = $obj;
}

make sure that str_replace is there as '-' is not allowed within variable names in php, as well as:

Naming Rules for Variables

* A variable name must start with a letter or an underscore "_"
* A variable name can only contain alpha-numeric characters and underscores (a-z, A-Z, 0-9, and _ )
* A variable name should not contain spaces. If a variable name is more than one word, it should be separated with an underscore ($my_string), or with capitalization ($myString)

So, since these are permitted in arrays, if any of them comes in the $key from the array you are converting, you will have nasty errors.
