如何添加到stdObject数组？

Question

Here is the result of print_r($object):

Array
(
    [0] => stdClass Object
      (
        [title] => Test procedures in watermelons
        [nid] => 494
        [type] => chsmanuscript
      )

    [1] => stdClass Object
      (
        [title] => How to eat cookies
        [nid] => 520
        [type] => chsmanuscript
      )
)

How can I manually add a 3rd object item in this object array? I have tried the below but it does not work:

$object[2]->title = 'test';
$object[2]->nid   = '999';
$object[2]->type  = 'chsmanuscript'

The error is: Fatal error: Cannot use object of type DatabaseStatementBase as array

Answer 1

You must first create a new stdClass object in the specific array element before you try to access it's members:

$object[2] = new stdClass();
$object[2]->title = 'test';
$object[2]->nid   = '999';
$object[2]->type  = 'chsmanuscript'

Answer 2

 $object[] = (object)array('title'=>'test', 
                   'ndid'=>'999',
                   'type'=> 'chsmanuscript');

This pushes to the array , if you need it to push at the third position, specify that in in $object[#]

Answer 3

您也可以这样做

$object[2] = (object)array('title'=>'test', 'nid'=>'999', 'type'=>'chsmanuscript');
