Different way to convert object to array using PHP - php

Question

When use this code:
$array=(array)$yourObject;
The properties of $yourObject convert to index an array, but how can convert as one array, these means, the $yourObject be one index of $array and I echo $array[0] for access through object?!
Another way for question, please see this sample code:
<?php
$var1 = (string) 'a text';
$var2 = (array) array('foo', 'bar');
$var3 = (object) array("foo" => 1, "bar" => 2);
//It's OK.
foreach((array)$var1 as $v) {
echo $v."<br>";
}
echo "<hr>";
//It's OK.
foreach((array)$var2 as $v) {
echo $v."<br>";
}
echo "<hr>";
//It's NOT OK. I want through $var3 in output as an array with one index!
foreach((array)$var3 as $v) {
echo $v."<br>";
}
echo "<hr>";
?>
Other way:
I want use a variable in foreach but I not sure about type this, I want working foreach without error for any type variable (string, array, object,...)
For example I thinks must I have this sample output for some this types:
Output for $var1:
array
0 => string 'a text' (length=6)
Output for $var2:
array
0 => string 'foo' (length=3)
1 => string 'bar' (length=3)
Output for $var3:
array
0 =>
object(stdClass)[1]
public 'foo' => int 1
public 'bar' => int 2
And the end I sure the foreach return current result without error.

You mean to wrap your object inside an array?
$array = array($yourObject);
As mentioned by mc10, you can use the new short array syntax as of PHP 5.4:
$array = [$yourObject];
