将stdClass对象转换为php中的关联数组

Question

I need to convert this array

Array ( 
[0] => stdClass Object 
     ( [title] => primo ) 
[1] => stdClass Object 
     ( [title] => secondo )) 

to

Array ( 
[primo] => primo
[secondo] => secondo ) 

Tried different options, including typecast, still not found the correct solution

Answer 1

Use json_encode() and json_decode()

$arr = json_decode(json_encode($yourObject), TRUE);

json_decode() 's second parameter is set to TRUE .

Function definition:

mixed json_decode ( string $json [, bool $assoc = false [, int $depth > = 512 [, int $options = 0 ]]] )

That will convert your object into an associative array.

Answer 2

Finally I did it this:

$options = array('' => '<select>');
$results = $query->execute()->fetchAll();
foreach($results as $id => $node) {
  $value = $node->title;
  $options[$value] = $value;
}

Thanks for all your answer

Answer 3

Check this code please, I haven't debugged it...

$array = array_values($array);
$new_array = array();
foreach($array as $row){
   $new_array[$row['title']] = $row['title'];
}

Answer 4

$final_array = array();

foreach ($items as $item)
{
    $final_array = array_merge($final_array, json_decode(json_encode($item), true);
}

Where $items is the name of your array. Should go through your array of objects, convert that object to an associative array, and merge it into the $final_array

Answer 5

Simply use array_walk like as

$result = array();
array_walk($arr,function($v)use(&$result){ 
      $result[$v->title] = $v->title;
});
print_r($result);

Answer 6

To blindly answer the title of the thread, you can achieve object conversion to an associative array by simply casting it:

$array = (array) $object;

However, in the discussed example, rudimentary operations can help generate the desired data structure without using any built-in function:

$array = [];
foreach ($arrayOfObjects as $object) {
    $title = $object->title ?? null;
    if (!is_null($title)) {
        $array[$title] = $title;
    }
}
