Get first element in PHP stdObject

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

much easier:

$firstProp = current( (Array)$object );

Correct:

$videos= (Array)$videos;
$video = $videos[0];

$videos->{0}->id worked for me.

Since $videos and {0} both are objects, so we have to access id with $videos->{0}->id. The curly braces are required around 0, as omitting the braces will produce a syntax error : unexpected '0', expecting identifier or variable or '{' or '$'.

I'm using PHP 5.4.3.

In my case, neither $videos{0}->id and $videos{0}['id'] worked and shows error :

Cannot use object of type stdClass as array.
