Returns a descriptive type name, including an object class name instead of the generic word object.
What It Does
gettype() reports object rather than the specific class Unlike gettype(), this reports class names for object values; useful in diagnostic TypeError messages.
Requirements and Compatibility
Available in the PHP runtime; use PHP 8 or later for the shown typed, modern examples.
Syntax, Inputs and Results
The arguments shown below are concrete values for this function; their types and ranges matter. The example checks return data rather than assuming that every operation succeeds.
Example 1: Basic Use
Demonstrates the primary behavior.
<?php
foreach ([42, null, new DateTimeImmutable()] as $value) {
echo get_debug_type($value), "\n";
}Example 2: Another Case
Handles an alternative input or use case.
<?php
function expectString(mixed $value): string {
if (!is_string($value)) throw new InvalidArgumentException('Expected string, got ' . get_debug_type($value));
return $value;
}
echo expectString('ready');Practical Example
Puts the function into a larger practical task.
<?php
$payload = ['id' => 10];
echo 'Received: ', get_debug_type($payload), "\n";For production, apply the compatibility and edge-case limits described below.
Important Behavior and Edge Cases
Unlike gettype(), this reports class names for object values; useful in diagnostic TypeError messages.

Common Beginner Mistakes
| Mistake | Correct approach |
|---|---|
| Calling get_debug_type() without its required input or supported extension | Check the extension, supply valid arguments, and handle false or exceptions according to the function. |
| Assuming get_debug_type() guarantees a valid or safe image | Inspect the return and avoid exposing debug output to website visitors. |
| Confusing the operation with a related API | gettype() reports object rather than the specific class |
