This array could be looped through and data could be retrieved. As you are saying its not working I have added the following code to illustrate how it works right from generating the array for you.
// generating an array like you gave in the example. Note that ur array has same value
// for all the ids in but my example its having different values
$arr = array();
$init = new stdClass;
$init->id = 252062474 ;
$arr[] = $init;
$init = new stdClass;
$init->id = 252062475 ;
$arr[] = $init;
$init = new stdClass;
$init->id = 252062476 ;
$arr[] = $init;
print_r($arr);
The above array is same as yours
Array ( [0] => stdClass Object ( [id] => 252062474 )
[1] => stdClass Object ( [id] => 252062475 )
[2] => stdClass Object ( [id] => 252062476 )
)
Now the following code will loop through and get the data as
foreach($arr as $key=>$val){
echo $key.' ID is :: '.$val->id;
echo '<br />';
}
The output will be
0 ID is :: 252062474
1 ID is :: 252062475
2 ID is :: 252062476
