ReflectionClass inspects the definition of a class, rather than running its constructor or calling its methods.
What Is Reflection::getModifierNames in PHP?
Reflection::getModifierNames() translates a reflection modifier bitmask into readable names.
Reflection::getModifierNames(int $modifiers)
Parameters:
$modifiers— Required. The modifiers argument used to configure this operation; its accepted values follow the declared PHP type.
Example 1: Understanding the Basic Behavior
<?php
$modifiers = ReflectionMethod::IS_PUBLIC | ReflectionMethod::IS_STATIC;
print_r(Reflection::getModifierNames($modifiers));
Output:
Array
(
[0] => public
[1] => static
)
Explanation: Reflection::getModifierNames() translates a reflection modifier bitmask into readable names.
Example 2: Testing Another Case
<?php
$modifiers = ReflectionMethod::IS_PROTECTED;
print_r(Reflection::getModifierNames($modifiers));
Output:
Array
(
[0] => protected
)
Explanation: The returned names depend on the modifier bits; modifiers differ for classes, methods and properties.
Practical Example: Applying the Operation
<?php
$modifiers = ReflectionMethod::IS_PRIVATE | ReflectionMethod::IS_STATIC;
print_r(Reflection::getModifierNames($modifiers));
Output:
Array
(
[0] => private
[1] => static
)
Explanation: The returned metadata may be false, null, an array, or a Reflection object depending on the requested property.
Important Behavior and Edge Cases
- The returned names depend on the modifier bits; modifiers differ for classes, methods and properties.
- The returned metadata may be false, null, an array, or a Reflection object depending on the requested property.
Comparison With Related Approaches
| Approach | When to Use It |
|---|---|
Reflection::getModifierNames | Reflection::getModifierNames() translates a reflection modifier bitmask into readable names. |
ReflectionMethod::getModifiers() | Direct method and property calls operate on objects; ReflectionClass inspects declarations and their attributes. |
Common Beginner Mistakes
| Mistake | Correct Approach |
|---|---|
| Treating metadata returned by Reflection::getModifierNames() as though it executes the reflected class member. | The returned names depend on the modifier bits; modifiers differ for classes, methods and properties. |
| Choosing ReflectionMethod::getModifiers() without checking whether it provides the same result. | Direct method and property calls operate on objects; ReflectionClass inspects declarations and their attributes. |
Key Takeaways
- Reflection::getModifierNames() translates a reflection modifier bitmask into readable names.
- The returned names depend on the modifier bits; modifiers differ for classes, methods and properties.
- The returned metadata may be false, null, an array, or a Reflection object depending on the requested property.
The examples demonstrate where Reflection::getModifierNames fits within reflection and metadata. Verify the relevant preconditions whenever you adapt the code to real data.
