get_declared_classes — Returns an array with the name of the defined classes
У цієї функції немає параметрів.
Returns an array of the names of the declared classes in the current script.
Зауваження:
Note that depending on what extensions you have compiled or loaded into PHP, additional classes could be present. This means that you will not be able to define your own classes using these names. There is a list of predefined classes in the Predefined Classes section of the appendices.

<?php

{
case Foo;
}
var_dump(get_declared_classes());
?>
Result:
array(116) {
...
[115]=> string(3) "Bla"
}The array returned by this function will be in the order the classes were defined / included / required and this order does not appear to change.
For example:
<?PHP
//define classone
class classone { }
//define classtwo
class classtwo { }
//This will show X classes (built-ins, extensions etc) with
//classone and classtwo as the last two elements
print_r(get_declared_classes());
//define classthree
class classthree { }
//...and four
class classfour { }
//Shows the same result as before with class three and four appended
print_r(get_declared_classes());
?>
Output:
Array
(
[0] => stdClass
[1] .... other defined classes....
[10] => classone
[11] => classtwo
)
and...
