property_exists
PROPERTY_EXISTS(3) 1 PROPERTY_EXISTS(3)
property_exists - Checks if the object or class has a property
SYNOPSIS
bool property_exists (mixed $class, string $property)
DESCRIPTION
This function checks if the given $property exists in the specified class.
Note
As opposed with isset(3), property_exists(3) returns TRUE even if the property has the value NULL.
PARAMETERS
o $class
- The class name or an object of the class to test for
o $property
- The name of the property
RETURN VALUES
Returns TRUE if the property exists, FALSE if it doesn't exist or NULL in case of an error.
NOTES
Note
Using this function will use any registered autoloaders if the class is not already known.
Note
The property_exists(3) function cannot detect properties that are magically accessible using the __get magic method.
